Hello and thank you both!
Yes! Dala. He reads messages. I should try reaching him.
Yes! Bluetti. Hah, that is exactly why I was asking.
But they only deliver 1 type of voltage, so I'd have to decide between (possible) car-charger at 110 or home-use at 230.
For solar-re-charging, I need a specific one, because I have a big 24V panel. Only the AC200MAX
(for 2000+ moneys) and the affordable AC50S
will charge from panels with that voltage.
The big one delivers 2kw+, so that would be really nice and work okay with 230x6A- but expensive and heavy. But the small one will only deliver 300W on 230V - interestingly also on 110V, so double the Amps!
Hm. I might just shell out for the 2kw / 2kwh Bluetti for a proper home-backup and proper reserve-battery for the road. However 2200€ vs 450€ is quite an investment.
Thanks for thinking with me and cheers!
