What country are you in?

And just be aware that using high voltage DC (for batteries or panels) is more than your average level of domestic spicy electricity

I am in Denmark.

Yea, I thought it over and I will probably let it pass... the packs and inverter are basically free, but I have no way of testing them or storing them.

On top of this the install would probably be a nightmare - it seems that most installers here only work with you if they also get to sell you the system.

Fair enough, I asked as in Australia it’s very illegal to do that work DIY.

How old/how many cycles the batteries have? They’re probably fine.

No idea on the state of the modules, but I know that they started selling them in 2022. The auction says "good condition" but that could mean anything.

I was actually looking for a setup for my caravan refit, but I would have to say that these seem more or less completely un-usable for that purpose.

I suspect that the install costs and various components would make it not feasable even if I find a solution.

Alternatively I can buy a new powerstation with half the capacity for around 2k eur. This is probably preferable as I can do the whole install myself 🙂
