    The inverter will need at least 3X the fridge's rated running load in surge capability to start the motor. Low frequency are much better at this than lightweight High frequency. Don't believe the hype HF inverters are shyte compared to LF. Cheaper to manufacture and ship that's what the propaganda is really about.
    Can't all be buying fancy ones like the one you have. :P


    Ya can if ya pick up a used wan. I've no problem with €600 fridges when they're €150


    I have sockets in the old van but were only wired to the 240 hookup.
    I have a mind for a switched system which goes to 240 when plugged in but switches over to the inverter when the power is unplugged.


    There's a few ways to do this of varying complexity and expense.


    A manual ChangeOver is probably the cheapest and easiest.

    Kraus and Naimer make the best changover cam switches and bargain used ones pop up on ebay all the time.



    You can Double Up on sockets but this is a bit untidy.


    534413.jpg



    You can use a 2PDT or 3PDT relay but it's very cowboy and might cost ya an inverter if it goes wrong which is a reasonable possibility when running inductive loads like a fridge. My van is setup this way but my inverter is only a wee 300VA that mostly powers a toothbrush.



    You can make an interlocking system with Relays and delay timers this is the best affordable automated way.

    Remember don't put the battery charger on the changeOver!!!

    There's two more methods as well come to think of it. If the inverter is big enough to power everything you will ever use then you can just make everything (except the battery charger) an inverter only outlet and size the mains charger to indirectly power everything through the inverter.

    If yer going high end inverter-combi charger then the transfer is automatic and built in.

    Back to work after a weekend sabbatical last week. Time away made me forget how rank this van was when I bought it.

    I took out the headliner and the plastics on the A & B pillars to give them a clean.
    They're black with dirt and need a good scrub. As expected there was a load of filth behind the plastic on the B pillar too.
    I also have a reversing camera to fit, so I can do this before the liner goes back in.

    IMG-20201205-145616.jpg

    IMG-20201205-150742.jpg

    I also took out the seatbelts. The drivers one needs a good ironing since it's all twisted, and the passenger one looks bolloxed. it won't allow the belt to pull out now, only inwards and the roll is full.


  • Registered Users, Registered Users 2 Posts: 6,260 ✭✭✭Buford T Justice


    Figured I'd start the interior behind the drivers seat. Since the seatbelt mechanism is out, I stuffed the B pillar with some recycled plastic to get some insulation. Stopped at the bottom opening, since I don't want to foul on the belt mechanism when it's backin.

    I ran a 20mm2 cable for power to this opening from the back of the van inside flexi conduit. This kit came with glands so inside the panel there's a gland where the conduit is fixed and screwed through the hole that was drilled. Doing this now so I can install a panel on the wall now and have it insulated and donezo so to speak.

    I'm sure Sir Liam will tell me that the cable is under rated, but at €18 a meter for 40mm2 I said I'd go with the smaller dimension. It's inside conduit so I can always replace it in the future easily if I need to.


    IMG-20201205-155145.jpg

    IMG-20201205-155150.jpg

    Also, hat tip to Liam, I've bought 15m of that led light for something like €15 euro, and should be here before I'm ready to do anything with the lighting so that's a win.

    I've asked about the shipping on the b2b charger before I low ball them. At this point I'll either buy this one or keep with the split charge that i already have and do a retro fit at a later time

    Nope. :confused:
    Yer putting the battery too far away from the alternator instead! :pac:




    but at €18 a meter for 40mm2 I said I'd go with the smaller dimension.
    €10 €7.50 per m of 35mm²

    Make offer €150 + shipping to ireland in comments.
    ;)


    I'll buy that other wan so..let me kno if you want it in the Spring it'll be 25% extra...mate's rates :D;)

    Is that Pro-Nautic the same as the Sterling charger? I stuck a few bucks of a bid on it anway


  • Posts: 5,238 ✭✭✭ [Deleted User]


    I suspect it's better, I was going to buy it just to look inside...I'm a bit over 12v tho, really haven't much other use other than flipping it so I'll let her go fer ya. Sterling are using low build quality and cheap components in theirs. Sterling had a 2 year warranty, Promariner had a 5 year. Sterling painted the terminal cover red and went 5 year warranty a coupla years back.
    Drop yer final bid in the last 5 seconds, helps prevent bidding wars and people only bid to beat the bid, it's a much more profitable tactic.

    They shared the blueprints. Promariner seem to spend the money on reliability whereas Sterling invest it in warranty and BS.

    She's a good one. Well worth €140 even when yer done with it. No such thing as a third-hand product...:pac:

    RE: the far away battery, if you're using a B2B anyway you can put the battery in the trailer on that cable.


  • Posts: 5,238 ✭✭✭ [Deleted User]


    Oh and it works as a PSU too so you can not have a battery and still power up to 20A of stuff with it.


  • Registered Users, Registered Users 2 Posts: 6,260 ✭✭✭Buford T Justice


    Built a frame around the drivers side window today. It took an exceptionally long time to do - one of the more fiddlier jobs really. I imagine it'll make all the difference in the end. I mean honestly, it's almost as if I saw someone else to this before and copied it.

    Since the timber I used is 2 x 1, I had to add additional strips to it to fill out the dimensions needed. Added to that, I made the genius move of not bringing my chisels or box of screws with me so I ended up bodging with whatever screws I could find to do the job

    I added a self adhesive draught excluder to the bit sitting against the window.

    IMG-20201206-151215.jpg

    You can't see because of the darkness but the frame is only over the black sections of the glass so I can still get them tinted if I want to at a later stage

    IMG-20201206-171255.jpg



    There is a considerable amount of condensation built up on the roof, so it's dripping down whenever I move the van. Confuses the situation wit regards to leaks, though if it was leaking the floor would be soaked after a shower which doesn't happen. I might pick up a cheap de-humidifier and get it dried out, since it's only going to keep building up in the cold.


  • Registered Users, Registered Users 2 Posts: 6,260 ✭✭✭Buford T Justice


    I also borked the passenger side seat belt. It wound back on itself too far when I took it out and wouldn't come out again. I thought I'd be smart and open it and have a look to see if I could fix it..





    Yeah......





    Lucky for me I have two spare in the old van.

    Added some insulation to the panels. Its 100 mm insulation. Used spray glue at the top of the panels to hold the insulation up to prevent sagging over time.. and y'know...... gravity. I also waxoyled the bottom of the interior panels as I was at it, primarily since I had it left over and it couldn't hurt right?

    IMG-20201212-151428.jpg


    Have added vapour barrier over the insulation as it seems to be the done thing these days.

    IMG-20201212-174702.jpg

    Used a completely original idea of getting a router to smarten up the edges of the window frame so it would looks smart.

    Finished product so far. I have to run conduit and stuff for wiring at the back and I don't necessarily want to fix the panels in as of yet. Still the electrical ins and outs to figure out.
    I may start with the bed and the toilet next, depends on my mood I guess.

    Fitted the reversing camera today. Not because its a priority or anything, but since the roof liner is going back in this week it makes sense to hide the wiring loom while I'm at it. There's no power to it yet. I want to see if there a wire in the dash that can tell me if the van is in reverse to switch the camera on yet. I know it's at the gearbox, not sure if it makes it all the way into the dash

    IMG-20201212-134709.jpg

    IMG-20201213-135904.jpg

    The cable is too short to reach into the back door. I initially thought I'd just cut and solder in some wire to extend it, but then I figured I couldn't be arsed with it since I can buy an extender for €7. No point in making needless work for myself.

    I started to look at the passenger seat today too. The old base I have is from a transit, but an older model one. Ideally I wanted the new base to fit in the same holes that the one from the existing base seat had since they're already threaded with bolts.

    Sadly it didn't happen - the bolt holes don't match.

    I got my thinking cap on to see what I could do and since the old bench seat is scrap, I cut the base off it with the plan to re-use it. There was already on lateral piece of steel in the frame and I just needed another one but didn't have one... Or did I? As luck would have it the seat is made of the same tubular steel that the base is, so I cut the seat open and took a bar from it. Needs some welding and painting and we're all good. I'll tackle this welding myself, since it doesn't require any sort of finessing or that. It's ok if it looks like vomit.

    Base all cut down.
    IMG-20201213-155802.jpg

    New piece in situ
    IMG-20201213-155809.jpg

    Mock fit of the base sitting on top. It will need a piece cutting out of it so it doesn't obscure the bolt holes but it looks as though it'll be a straight forward enough build

    Question:

    If I have this split charge relay in the first instance, will this charger when plugged in also charge the starter battery if the voltage from the charger rises above 13.3 volts, or is it purely a one way operation?


  • Registered Users, Registered Users 2 Posts: 73,477 ✭✭✭✭colm_mcm


    Pretty sure that one doesn’t do that.


  • Posts: 5,238 ✭✭✭ [Deleted User]


    Ya misst the German B2B didn'tcha!? tsk tsk! €100! 60A! :rolleyes:

    Ah yersh that's bidirectional...and fairly shyte. It'll work as you say with your charger but if the vehicle is regen it'll cause you heartache and it's a bottleneck device made of bubblegum.

    Smartbank + a relay/contactor is a much more wholesome alternative. They're about £22 +P&P from over the pond outtov NHS ambulances


  • Posts: 5,238 ✭✭✭ [Deleted User]


    PS that charger is a 3 battery output pilgrim.

    I did. They wanted €40 to ship and payment via bank transfer only. Add that to the fact that they had 0 feedback (or maybe 1) put me off. Seemed a bit too dodge with no protection.

    On the plus side, AddressPal emailed me to say they've got the charger so that's on its way.


  • Registered Users, Registered Users 2 Posts: 6,260 ✭✭✭Buford T Justice


    Tried my hand at welding this evening. Figured it's not panel steel so I couldn't cock it up too much

    Once I got into it and used proper welding gloves it was a lot easier to get a decent bead going

    IMG-20201215-213538.jpg

    Though I knew it wouldn't be long before I ballsed something up. I planned to leave the bar I was welding in back far enough so as not to obscure the bolt hole. Naturally I was covering it slightly. So I cut the bar, hammered it down a bit and welded it back up. Jobs a Good'un

    IMG-20201215-204542.jpg

    Also welded the fixing point in for the seat belt to bolt into.

    IMG-20201215-213554.jpg

    That seems perfectly normal to me. Ze Germans are uncompromising about insuring their parcels. +€20 for that and not worth arguing about.
    £323 box for <€150 you'll be hard pushed find better.
    Speaking of dodgey...I'll sell ya my 120A for €150+P agus P...:pac:





    Re: the feedback. Person is selling off oddities this close to Xmas for quick cash, not entirely suspicious. Besides I usually find the Germans only sell pristine condition gear.


    I've bought €2.5k inverters from zero feedback sellers for £550. That's running my house right now.


  • Registered Users, Registered Users 2 Posts: 6,260 ✭✭✭Buford T Justice


    Sir Liam put me on to a b2b charger that I managed to pick up for a steal on ebay. Actually, credit where it's due he also managed to find me a 20A Battery bank charger for a song too.

    I bought it this morning after talking to the seller & had the delivery address as parcel motel. Very efficient seller shipped it earlier today, and I got notified. Estimated delivery the 26th of December to Parcel Motel address.

    Around 3 hours later, I get an email from ParcelMotel advising that they will no longer accept deliveries to ParcelMotel in NI from the 28th of December

    So.... depending on how things go, this box may or may not get to parcel motel in time and they (say) they'll refuse to accept deliveries from the 28th.
    Poor form from ParcelMotel - Parcel wizard contacted me in November to say they were closing their drop shipping location.


    The wait is on!


  • Posts: 5,238 ✭✭✭ [Deleted User]


    Stole it is right! Jaysus, not many bigger ones. Maybe I'll put a punt on thuther wan...hrmm...

    Er...well fingers crossed but I've been waiting 3 weeks for some stuff to make it to the Uk addresspal depot (still operating post brexit) in my closing down sale trolley dash.

    If they return it to the seller request addresspal or use parcelforce or someat and you might get hit for import duty which won't be much.

    Nice negotiating, I thought it was ending Monday.

    The lead he chewed through with a blunt badger is the ground and comes fused from factory (because they underwire it and use the chassis ground to supplement it).

    Let me know what guage it is and I'll recommend a fuse. The stock blade fuses melt the holders, Mega fuses are much better. The input and output need 80A fuses too.

    The rest is in the manual. Don't be lazy, wire the sense leads too they're important.
    If the fan bearing is any way questionable or it doesn't spin when you power it up then replace it.

    Well wear.


  • Registered Users, Registered Users 2 Posts: 6,260 ✭✭✭Buford T Justice


    Oddly, the docs say nothing about a fuse on the ground, only on both sides of the 12v. I'm not disagreeing with you, I'm just one of those guys who reads the manual...

    Thankfully fixing that bodge is easy enough.


    And you say people don't listen to you........


  • Posts: 5,238 ✭✭✭ [Deleted User]


    That's because it's a factory bodge fly lead. The fuse is fitted at the factory because the ground is way undersized and if the chassis ground from the engine battery is lifted it'll ignite without it.

    I really don't know why they do it. If they're that tight over a few grams of copper then why bother..give us a stud so we can do it right. They're an odd bunch, the hardware does work but it's not worth the asking price by a long shot...the build quality isn't great.
    Not that they'll ever admit it. I've tried explaining it to them. They want to be like Victron...that cracks me up...I told them aim higher.

    Here's the pic of mine.

    I think; Ask, Listen, Then do what they were going to do in the first place anyway is more normal.



    That's why I only do live-aboards or bigger, they've already bought into the marketing, realised it was hollow and are prepared to pay for solutions that actually meet specification.

    I finished the passenger seat earlier in the week, but since it was dark I didn't bother with any photos at the time.

    IMG-20201219-140352.jpg

    Notice that the seat belt is fixed to the bottom of the bracket. As it would happen there are mounting points on the swivel bases for seatbelts and they're the same thread as the existing ones, so I've moved the mount to there. Its a pity I didn't see that earlier in fairness, as I wouldn't have bothered welding the bracket to the base that I did earlier.

    I also noticed that the B2B charger that I bought has a temperature sensor for the device, so I suddenly had a need for additional cables where I had run the cable previously. Since I had flexi conduit and glands left over I ran another length of it with two runs of two core cable inside.

    IMG-20201219-152958.jpg

    I cut a hole in the bottom of the B pillar so I could properly feed the cables through and out at the bottom of the pillar via glands.

    Yeah it almost works except undermined by not doing their research.
    Use it because it's better to have it but the compensation is half of what it needs to be and the maximunm output of the unit is limited so it stops compensating below 5°C on the flooded battery profile.
    You'd think they'd do better for a £360 box wouldn't ya?
    Probably wasn't anything left in the budget after the warehouse rent and warranty claims were factored. :rolleyes:


    They don't really design hardware so much as copy what's already on the market or rebadge things.

    The temp sensor goes on the house battery by the way which I'm guessing lives at the end of the red cable with the B2B?
    You could stick it on the van shell. It just wants to be heat sinked to a metal lump in the same environment. Sure the battery is more accurate but lump of lead or internal body tin...usually the same temperature.

    Nice touch with the anti chaff grommits, a lottov people don't and regret it. Don't forget the seat base.
    Screwfix do bags of 100s of rubber wans for peanuts.



    PS. when I'm opening up access like that if you only cut three sides and bend it, it's much easier to repair after.

    Aah, up there for thinking......

    Though I deliberately wanted to plate over the hole. The welder I have will burn through the steel if you're not careful, and though I'm ok with welding heavier steel I'm not skilled with lighter stuff. It was easier to do that rather than to try and bridge the gap and risk burning it through


  • Posts: 5,238 ✭✭✭ [Deleted User]


    TIG country stuff that light. Always the last machine people pick up.

    Santa's bringing me a 180A inverter stick welder. Looking forward to it. Too many jobs around here I'd do if I could only melt metal together myself. Bittovan expensive habit...I won't be happy until I have a multi-process machine.

    I reckon I can power the welder with my truck. :cool:

    Wouldn't worry too much about the extra cables, fiver says you'll use 'em for something.

    So this is interesting.

    Where is this coming from I wonder?
    Its not a leak at the top of the glass since it's not running down the glass on the inside, and after the weather we've been having it's not a lot of moisture to correspond with a leak.

    There is a 2x1 baton behind this join sandwiching it together, but it's behind the vapour barrier. I wonder should the barrier be behind the batons.

    The only other thing I can think of is there was a few drips of water on the back of the barrier when I took the panel off to re-run wires. It could be those drops have hit the screw and run out through to the front, though I'm not completely convinced.

    I did a dry run of the layout today. Marked out the depth of the bed and using 1 meter for the toilet (since that's what the last one was) and I put the seat in front of it. There's some things to notice.

    IMG-20201228-161018.jpg

    There seems to be ample space between the drivers seat and the back seats to have a table in the middle though it's dubious as to if it can be fixed to the side of the van because of the window. Maybe, maybe not. Added bonus, the seats seem to all be the same height.


    IMG-20201228-161036.jpg

    It's also occurred to me that the cables I've run are directly in the line of the cassette door when it comes to removing the cassette. I'll need to mingle around that when it comes time.

    I built the boxes to cover the wheel arches so they can be insulated. They won't be fixed in place just yet, but I needed them in order to have dimensions to be able to lay timbers on the floor of the van for the bed.

    This came today, my new battery charger. It's larger than I imagined it would be, so here's a remote beside it for scale

    My B2B charger that I stole bought on ebay was delivered to parcel motel on the 23rd December, before their brexit cutoff date but as of yet I've not had any notification from them. I'm hoping it's due to volume but I fear it could be a lost cause.

    So I need some advice here, in particular from people who know more than I do (you know who you are).

    Bearing in mind this van will only be used a number of times a year and not as a permanent live aboard thing I don't want to go completely crazy on batteries.

    I've settled myself on two house batteries. I know I can get heavy duty batteries from my local motor factors for around €120 (ie starter batteries for a transit), but in looking around I can get two 110AH 'Leisure' batteries for €130 each, and free delivery from here

    Is it worth my while getting the leisure batteries, or will the starter ones that I can get do?

    Shiney. Wanna take it apart so we can see what's inside? :o

    Don't give up so easy.
    Use this "find my parcel"
    Enter the original british tracking number. Most private sellers just ignore the virtual address identifier code. As with a lottov things if they don't understand it then it's probably not relevent. You can ask the seller for the tracking number if you can't find it.

    Those "leisure batteries" are starting batteries with expensive stickers, if you want genuine ones then try here


    I'm rockin' Crowns and I'm here after 5 years as a 6month annual live-aboard.

    Battery Odometer: 11300Ah since install.

    People say you need a leisure battery because it gives you 300 more cycles. Those same people kill it after 20. The problem is the charger not the battery but people never fix the charging system they just throw batteries at it and then complain they're junk.


    You oughta be fine for 5 years easy with whatever you choose, the use yours will see as long as you keep them charged/get solar.


    I'm playing with LiFePO4 atm....what a waste of money..:rolleyes:

    Those batteries are too expensive for me at the minute. I'm not against them if they're the right job, but not in this phase of the build.

    That being the case, locally I can get a 70AH for €100 + VAT, but for an extra €9 each including free delivery I can get these, so I'm assuming I can get a total of 220AH at 12V?
    The latter would be a better option?

    In terms of now long I get out of them / keeping them charged. In the case of Longer term storage in the winter will the ProMariner charger keep them topped up at minimal energy usage once the batteries are charged?

    I also phoned parcel motel today and by fluke they actually answered the phone. The knew what I was looking for straight away. It was shipped but the seller never put my PMID on the label. It's in Dublin now so waiting on it to be shipped to my local locker.

    The bigger battery sounds better value.

    I'm an advocate of the phrase "Don't go half bitch!" ...Nobody'll respect you.
    Meaning if you want cheap, go cheap!
    Leisure batteries are rebadged starting batteries. If you want a true traction battery they don't come in 12v unless you go AGM.

    So going with a cheap a$$ engine staring battery rated to 80% plated capacity after 300 x 100% depletion cycles.
    When you think most people use a camper 12 weekends a year and get 2 years outtov the battery that's at most less than 100 50% cycles...so the batteries aren't failing from use and what they are failing from a good one won't do any better.

    Next on the hitlist. 80% depth of discharge is fine. 30% more runtime and 30% less cycles. Compared to 50%. All the graphs agree.
    Next, next thing is alternator efficiency. The lower the state of charge is the higher the alternator output so if you discharge the battery to 20% you can charge it back up to 50% in about half the time as if you went 60% to 90%.

    Next, next, next thing is a battery is not as valuable as a solar panel. The battery does not "make" power. Save money on the battery and spend it on the solar.
    Solar has a resale value, will reload a battery on the go and lasts 30 years.

    As regards keeping the battery topped up yes the ProMariner is about 20 times better than that other yolk you have for this. It's very good at maintenence you can leave it on 24/7 and it will cost I'd say <€0.20 a day in lecky.
    I think solar's much better for this purpose too but either will do.


    You'll need to periodically water a battery on that Sterling B2B every so often so try to find one with serviceable caps.


    The last next thing; you mentioned a 2kW inverter. You can't run that off less than 200kg of traction lead it can't give the surge. But an engine starting battery can. Don't expect either to run it for very long.

    For me, this isn't a one off job, so i'll be doing things like solar in phase 2. I'd like solar but I don't need it as yet - I want a van that we can use this year within budget, given the current situation. I can sex it up once its on the road.

    Given your advice I'm thinking of using a 240V under counter fridge, as you say it's far more efficient. Do I need a 2KW inverter? No, I don't suppose I do - but I'd need an inverter of some sorts to run the fridge plus some ancillaries... ie a phone charger, tv that sort of thing. As for a kettle I have gas for that. Mind my last van we only had 240 when we had sore power and we never missed it.

    So I'd need an inverter that could keep going while parked up with no shore power, but not for weeks on end either. I think 2KW is over engineering. How does 500W sound, or what would be preferable?

    D'oh! I sawr a beauty of a yellar Xantrex 1kW go two week ago I was gonna tell ya about but reckoned you wanted bigger.


    Er yeah 2kW is mad in a van with gas, I'd fit 600Ah beside it.


    You'll want a 1kW with a sleep function for the fridge because them compressors are tough to start.


    Tvs and USB come in 12v and running them off an inverter has horrendous efficiency. Add a DC-DC reg for a 12v/24v etc telly to give a stable output instead of charging voltages or inefficient rectified sine waves

    My kids have fairly big tablets, so an actual tv may not be a thing - more likely to use them for netflix or whatever, and they're already suitable for 12v.

    £5 for USB QC3.0 these days

    Don't put small loads on an inverter and you can double your range.

    I've looked at some arbitrary under counter fridges online and I can only find the annual consumption in KWH for them. How many watts roughly would they use per hour, and would there be much power loss due to it?


  • Posts: 5,238 ✭✭✭ [Deleted User]


    A decent fridge between 150Wh and 500Wh a day depending on ambient temperature, condenser cooling & ventilation, fridge insulation, refrigerant remaining in the system and the frequency at which you open it.

    The inverter on consumption can be 720Wh (Sterling Poower) to 12Wh (Studer SI with a low load sleep function) a day or anywhere in between.

    I think those Yeller Xantrex have a sleep function, if it's adjustable even better. Dunno...rtfm..

    This arrived today. The ground cable is 4mm thick.

    Lovely Sterling, nice work. :rolleyes:
    32A cable on a 50A appliance.



    30A fuse so if it's 80°C insulation.
    40A if it's 105°C


    If you've regen set it to regen. Otherwise, ignition switched. If you use automatic it'll create a feedback loop on mains charge or solar split charge.


    Most performance setting with highest water consumption = Open Lead Acid
    AGM 1 = least battery maintenence
    Sealed = in between.
