In this mode are the panels live or disconnected. My understanding with most backup setups is that the panels are still disconnected in a power outage as well thus your only operating on battery and to be honest i think its designed that way - eg in a fire, firemen disconnect you from mains and also knocks out fire safety switches supplying DC power coming from panels.
With a switch like Garo was suggesting means your manually reneabling the full/partial board and also the fire safety switches thus you can run on battery and PV
Yes that's what I meant. When there is a powercut you inverter will automatically stop sending power through the normal A/C output and will instead send power through the EPS/backup output. But if the backup output is connected back to the main board then it is connected to the mains. If instead, your electrician has created a dedicated circuit that only has power through the backup (and is thus without power when the mains are on) then you are ok.
Yea, when I built I put in one of those big Schneider boards so plenty of room to move stuff around. Otherwise a mini board will do the same job.
The panels are live and only live circuit comes directly from the inverter AC/backup socket.
I have 4 new isolators also insisted on by the sparks so everything can be shut off if needs be.
ESB require this cert which proves the machine will not send power back into the grid in event of power outage.
The hybrid inverters are the job and even while I was installing the suppliers weren't 100% of their full functionality but yea they can fully power the house & battery via panels on a sunny or bright day and power the essentials via battery in the evening.
The point being missed is that for the SEAI grant they require the fireman Switch - which is a contactor on the DC panels.
That is enabled using AC from the grid- in the majority of installs that is fed from the AC isolator of the inverter, so if you shut off the grid AC (either by switching the isolator or the grid going down) to the inverter, the fireman switch is disconnected, thus the panels are disconnected and you are on Battery power only. nothing to do with the anti- islanding of the inverter.
You may not have a fireman's switch. - thus you don't have that issue.
How the house handles that changeover is a whole different discussion.
This starting to go off track lads/lady's.

Indeed. Could a mod move all the posts from samdeluxjones' 31-07-2021 1:15PM post to this to the othe thread? Thanks
Have a quote for house retrofit program that includes, insulation, Air to Water pump, 2kw PV system + some other measures.
Price options for going bigger on on the PV system:
Upgrade to:
4kw system -> 1200 extra
4kw system w/ battery-> 3200 extra
6kw system -> 2400 extra
6kw system w/ battery-> 4400 extra
Leaning towards a 6kw system with no battery & assess adding a battery down the road when the FIT starts.
Or should i put the battery in now while I still have grant access?
6.75kw system, that includes 18 panels, 6kw Inverter, 5kw battery and Energy Diverter(free).
Based on our high consumptions they have designed system of 6.75 kw so that it can reduce the electricity bill up to 80%.
Nett of grant 10,500.
That's ott on the price by about 20%. That free divertor is very very expensive.
The other quote was 12000.
Holy hell. Pm sent
My personal view is battery now as there is some form of a grant available and go for the most amount of panels you can afford.
Get a few more quotes for the larger setup, im sure the lads/lady's will happily send on a few references.
Could somebody please PM me some reasonable places to get a few quotes from. I am in the Mid-West.
Also, what kind of system should I be looking for (200sqr m well insulated house, probably not much space on the roof due to 5 Velux windows but we have a detached garage with a lot of roof space and no windows there).
Many thanks for any feedback.
Every page here should start with a note with the guide
€1000 per kWp of panels after grant is the MAX that you should be paying.
Sure you can get about 2.5kWp from solar as a service for €2400
Hi, I have a call back from them on Monday and just want to know is it a good starting point? As in can you add on to the system easily in the future and are they good value or would I be better off waiting and getting a bigger set up in about 6-9 months? Any info appreciated.
If you're willing to pay upfront for extra panels a deal can be done.
Thanks, I'm just trying to see the options for adding what I can in the future so i'm not stuck with something not suitable. I have other priorities to do before I could just buy a good system outright for now.
We got 9 panels. Paid for 2 upfront and the rest over 10 years.
Didn't get the eddi. It's too expensive from them and I don't think we'd have enough excess to justify it.
Same as that, got an extra free panel and paid for another extra panel off solar as a service upfront. Then got an edii myself on eBay for good price as way too expensive off them paying monthly.
Adding afterwards is only really worthwhile if you can DIY. It's very simple really, and the roof brackets are possibly the most difficult part.
SaaS is perfect for a DIYer. Gets you signed up with ESB Networks, and gets you a certified install, ready to just add extra panels and possibly a DIY battery
wow very nice...information.......
Go as big as you can afford, get 3 quotes and references, I'm a fit and forget type of person. Yes i could do the DIY but i couldn't be arsed.
If you want the name of the company I used just PM me.
With brexit it's a cheap to buy one here.
Got a quote of 4700 after grant for 3.8kw with an Eddi
Are people really getting quotes of 1000 a kw ?
You're being robbed.
I paid 3200 for 3.24kw and an Eddi will only cost you about 500 to buy yourself.
They're charging 500 for eddi alright it's the rest that's expensive so
I wouldn't say this is being robbed but is a bit on the high side. Is your install any way complicated? Are the panels being split on two sides of the roof? Is the cable run long? For that price - and without a battery - I would be looking for a few more panels. If they throw in 2-3 more panels free then it's beginning to look good.
Thanks,Install should be straightforward, no issues , 11 panels seems to be max on that face of roof as its a hip roof , that quotes was for 10 panels
Your best bet is to go with SaaS for 7 panels and negotiate the additional 3. In 3 months time, you can always just buy out the deal and fully own it, or get the 7 panels from them for 2400, and DIY the last 3 panels after buying it out
It seems that there is a mix of people buying systems outright, or using solar as a service. Why choose one over the other. Can anyone please direct me to a list of benefits and downfalls for both?
