Solar PV battery options

DIY, so no subsidy, so no inspection? Just make sure you can not export more than 6kW

Thinking of picking up another 16 LifePo looks like the price after coupon is €1477,41, not sure if it will get much cheaper than that? What do people think?

Would love to order the longer seplos voltage reading cables too for peace of mind, any idea if you can order just that?

No grant no. DIY; apart from electrical work done by a registered electrician (just adding a new circuit to the consumer unit and giving me a cert for that).

ESB NC6 form submitted also. So I’m all good for FIT too. No need to get SEAI involved.

Who would be doing an inspection?

Posted this in the Solar for Dummies thread, along with a couple of queries, but as this is a specific battery thread it might be more appropriate here. I was talking with an installer about installing a 5kwh battery and his strong preference is to install 2x 2.5kwh batteries instead as this would be a more scaleable option allowing increases in 2.5kwh increments in future rather than in 5kwh increments. Dont see the point myself as I would like to increase to 15kwh of battery over next couple of years so end up with 3x5kwh batteries. Is there any disadvantage to going with 2.5 kWh as against 5kwh batteries in this context?

Thanks, that's what I was thinking. It's actually dryness batteries but I think they are pretty similar. He did argue that if was was adding batteries in future, it would be easier to work with lighter 2.5kwh especially as I'm considering putting them on brackets attached to a concrete wall to safe on space. Ultimately however it will, be the same weight per kWh and that's the important metric. Did anyone put batteries on a wall and what kind of brackets did you use? Is it even advisable?

I have 10kWh of huawei on the wall. Used the optional wall bracket they have. I think it’s 6 16mm bolts. It’s solid. Supports up to 15kwh of battery and the controller per bracket. Some of the other manufacturers support wall mounting out of the box.

Can't get anywhere close to that price for 10kw Huawei in Ireland from what I'm looking to buy (midsummer), could you pm supplier if ok? nearest I could get is that Spanish website at €7k delivered

@Pavlova lova €7287.75 - From midsummer.ie including VAT and delivered. The prices they display publicly are inflated. You need to contact them and setup an installer account to see the real price.

@unkel the value for money is unquestionably better with DIY; it’s just that it’s beyond most people in terms of time and effort. I got my 10k huawei battery for 6500 (before recent price hikes). I’m satisfied I can hit 5-6Y ROI with my setup. I did DIY install all the gear; so I didn’t pay anything extra over the wholesale price which helps.

I have been looking at the PWOD site just now checking prices and the best I have seen so far for 4x16x200aH Calb is €5885.92 at checkout. Actually I only priced for 16x (@ €1471.48). On these ones the comments indicated in one case 130aH vs nominal 200aH. The more expensive Calb from PWOD quotes a nominal 190-200aH....although I supect they do not actually measure the capacity at all. Their grading of 'A', 'Brand New' or 'no grade' seems to to be ad-hoc at best.

Is there another link or discount code to get closer to €5k or is it only during a sale? Is there any method to deciphering their system at all?

In case it of any use to others....here is a spread-sheat of my efforts so far on pricing with PWOD.

Is it ok to add links to the product you ordered?

Just the 200Ah CALBS from PWOD, the link changes all the time, so old links often don't work or are out of date. See @graememk's advice. Check often.

Better to pay in USD. And the price in your link, €1469 is pretty much the "normal" price. Deal prices are more in the €1300-1350 range these days. Just checked my bank account and I actually paid €1351 two weeks ago

I'm scoping and speccing a system and in the course of getting storage prices. I was offered the below options inclusive of delivery and duties (DDP) from a German warehouse. Might be of use to other folk here as a guide. Price from Chinese supplier "Sunway Solar"

They do include VAT and shipping. It was quoted to me as DDP.

Price was quoted over email, I'd been in touch to price up DIY Vs local supplier.

No link to the price quoted but the website is http://www.sunwaypv.com/

I used the contact form there and some email back and forth led to the prices above. They seem to be clearing their imports via Germany so it's covered for VAT when delivered.
