Solar PV battery options

What model of dyness are they? I'd be interested in a least one when they are avaliable, if compatible with my own.

Answering couple of different posters here:

In fairness it’s a lot less money; but a huge additional investment of time and effort to get a DIY battery working and keep it running with no guarantees about the capacity of the battery’s that you are sourcing from a variety of shady Chinese suppliers.

Huawei 10k battery will set you back 7200 that’s with 21% vat paid to a reputable irish supplier.

To the other poster If you’re happy to go with a low voltage battery from some other manufacturers you could get 10kw in the region of 4000-5000 again that’s including vat at 21% from an irish supplier.

6kw solis hybrid is 1600.

6kw huawei hybrid is 1350; just incase your wondering.

both prices including VAT already.

Ive seen the prices; in that regard it’s night and day. I just personally would not feel comfortable buying from a seller that is known to be misleading customers about the capacity of its product. The hobby aspect of it is cool, I would like to do it myself in the future to expand above the 10-15kwh that I have will have; but for the primary storage / emergency backup I'd rather pay for something out of the box. I watch a lot of youtube stuff, and I can see the amount of effort that is required if/when something goes wrong.

There is no longer any grant for battery storage in Ireland, so thats a moot point.

How fast can you charge your 40kwh? It's a savage amount of storage.

I'm fairly sure that I will need to buy an additional 5kwh module to bring me to 15kwh total to be able to get what I want out of it. This would put me nowhere near being able to run a ASHP or infrared panels to heat the home, but for most other general use it will allow me to load shift. I think more panels is what I wanna do next... 7.4Kwp seems small.

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.
