Going off grid :)

Probably one for Rick but here goes

It looks like I might have scored a grant to get solar panels and inverter.
This is for my REWORX shop. It's my upcycling, reclaimed and bespoke interiors project, more of that again.
4kw system
The idea is to try and store as much as possible in batteries and use that to run my lighting displays in the shop.
Pretty much all of them are LED
Anyway, it's 24v and I guess I'll need many 1000 s of amp hours

What do I look for ? Budget is max £1200
Thankyouplease

Is that budget for pv panels, batteries and inverter? bit on the low side, youwill not get much for that sort of money, but why the inverter if you are running nothing but lights? Rick

£1200 is the bit we have for the batteries

Just checked the spec
Briefly: 3kw inverter charger with built in mppt solar controller.
ac/dc isolators, consumer unit and ac input and outputs
12 x 320w solar panels

I would need some reliability data for an all in one box inverter/charger(from the mains) and solar controller (also a charger) is the inverter pure sign wave, Rick

The batteries are a bit dear for 5 year old, Rick
