    Neozeds were causing so many problems on gold shield homes that the NSH had to be stuck onto a separate fuse

    The esbn fuse became the consumers main over current for a time

    Still plenty of installs out there with esbn as their main fuse

    Yup, and many with 6 or 10sq tails.

    Im not buying into this idea of fitting temp and smoke monitoring into main boards

    It's simply not needed on modern boards unless you've determined that the loading is causing an increased risk of overheating

    If that was a concern i would be removing the risk factor ie; the loading, not monitoring for smoke and heat

    And you're still only monitoring a single location albeit one with the likely greatest risk

    Youre saying that you will have probably the safest main board in the country because you're monitoring heat and smoke potentially caused by the 14kw loading

    Makes no sense

    If you were monitoring smoke and cutting power you'd probably be as well off have any of the interconnected alarms cut power to 14kw load rather than a single standalone alarm

    You might be able to place an alarm at locations such as the connected equipment depending on the location suitability

    These measures are being put in place regardless of load. If I wasn't drawing the load I am, I would still be doing the same thing.

    What heat and smoke caused by a 14kw loading, there is none?

    I've seen consumer units with loads no greater than an oven melt, If temp sensors had been installed, then the load would be removed before becoming a problem. My smoke detectors are interlinked too btw.

    This comment right here shows that you're out of touch with modern technology, I'm monitoring at any location I feel has a risk, at the inverter, Oven, shower, board, etc.

    Hi All

    Have been reading the treads and doing some research. Looking for 30kwh battery and hybrid (two string) inverter. Got a quote below, would ye mind taking a look and see what you think? The shipping is had to stomach. Any thoughts and other options. (Not going DIY)

    It's going to be circa 250kg in weight for the battery alone so the shipping cost from China reflects that.

    The cost of the kit itself is reasonable but hard to know the build quality without knowing the brand. The warranty isn't worth the paper it's written on.

    P.s. you might want to remove your eircode.

    My 15kWh battery from Gobel was €1600, plus €600 DDP plus €100-ish for credit card payment so I’d have some protection. Your quote is pretty close to that. Bear in mind shipping includes import duties, etc.

    Seplos with batteries from fogstar seems to be similar price or cheaper. What's the advantage of your route ? It doesn't appear on face value to be a better option?

    do you know, I never even looked - I assumed from all the talk of seplos and fogstar and nkon that these were all diy kits. Just had a quick glance there now and equivalent battery is GBP 2500 though?

    I worked out b class stuff for around 1800 euro ex shipping. It's a bit confusing what an extra 6 or 700 hundred euro is getting people here for the purpose of home storage. Are people over purchasing?

    You've one guy posting about regret but what's the real details as to why

    Guys looking at getting a bench charger to use on the Seplos (new when it arrives and existing), would the attached be suitable, I know it only does upto 5A but if inverter is used to charge battery upto say 98% then use the charger to do the top balance?

    That's a fair question, but at the time my comparison was against €2200 for an additional 5kWh battery from my PV installer so €2300 for 15kWh seemed pretty decent. There were also differences in cycles guaranteed, 10,000 vs 6,000. And I'm fitting into an attic space so I was a little uncomfortable with "B-grade" (maybe not so much now with further knowledge gained). I probably could've gotten cheaper and maybe I've over-spec'ed but I'm happy enough with my decision.

    No, worries . Just trying to understand people's thought processes. And value for money versus usability.

    Reducing monthly bills, having back up option when the grid drops out and value on investment to ensure it wont be a decade to get the return back need to be considered. Every house consumes differently so the sums need to be done. My plan is to ensure to have a good inverter which can take more panels if/when changed out (new panels will have increased out put) and add 10/15Kwh battery and scale year by year keeping a keen eye on technology

    Typically you wont be swapping your panels, the efficiency is only getting incremental gains year on year with new panels, the size of the panel is increasing to get more output. Chances of you swapping panels installed in 2025 by 2030 and making that cost back are slim to none

    I don't think you got the point of my post. It was about brand and battery type. Rather than a high level view of why someone would opt for home storage.

    There's been a few streams of inconsistent pricing. So people may be over spending unnecessarily. Devil's in the details.

    Have shipping sorted. Can get it picked up and delivered down south for an extra €80 which is cheaper and easier than driving for 8 hours. For those in the know do you reckon the v4 kit is worth the extra 100 pounds.

    Guys, picked up the Seplos yesterday back in Dublin now let the build begin, I have the Fogstar video and of course our own Ghost's video's also so I should be ok, if I get stuck I'll no doubt be posting.

    I've scanned all the QR codes on the batteries and all look well Eve power Jingmen July this year, I've measured all the voltages all are 3.28V.

    Should keep me off the vino tinto Christmas Day.

    Bought it in the Fogstar Black Friday sale last month, £1450 V4 with 314Ah EVE grade A cells and shipping to Northern ireland, £30 to collect, I have income in sterling so no exchange costs, seems like good value to me 16KwH, was looking at €2200 to add a 5.3KwH WECO to existing install, figure build Seplos get the sparks to connect and disconnect the two WECO's flog them should be a grand or so in pocket…..hopefully.

    Massive problems in holyhead are impacting all other shipping routes as hauliers pivot around that route.

    Maybe the run on the 280 cells is much bigger than the 314, mine was not supposed to be till January but got the mail week before last saying it was on the way..happy days, just need to get it built now.

    I am going to add a 10 kw Libbi battery to my existing 6 kw system . I am told that i need to upgrade my inverter so the quote is this

    Givenergy 5 kw inverter and 10 kw libbi battery

    Price €5450

    Does that sound reasonable ?

    Any input much appreciated

    Do you currently have a givenergy inverter?

    Why libbi?
