The stalemate had to be ended either way, I was becoming angry about myself.

I ordered the Bluetti / PowerOak AC200P and 3x 200W solar panels for 3200 coins.

Possible that I will need cable extensions, which should not be a problem.

Having a loggia in the oblique roof, I can lay out the three solar pads (2,0 x 0.5 m each) on the roof tiles if needed and have them close to a good angle towards the sun. Its the west side, fully sunlight hit he panels from early noon time on.

I plan connection cables holes to be drilled through the (wooden) sidewall, so that the unit can stay inside my flat even when beign attached to the panels. The panels are mobile, can be folded to bags 50x50 cm, 6 kg each. My solar setup options are not totally ideal, but solid, I estimate. And in the case of cases I could use a meters-long extension cable and set the panels up in the backyard garden two floors below me.

I will post experiences with solar charging in these autumn and winter season conditons. It might be of interest for others, too.

BTW, no Li-ion battery (danger of fire), but a LiFePO battery. Very durable: minimum 3500 charging-rechargign cycles. It can be charged via solar panels, wallmount, parallel with both (2.5 hours only!), generators, and via car batteries without needing inverters or any additonal equivalent (due to 12V in cars). Simultaneously consuming and charging is possible, too. 13 discharging options and connection mounts. The versatility is already inbuild, and I think that was an important point for me, it reduces the chance for falling victim to bad surprises.

The only setback: its not truely fully outdoor/weatherproof, the battery must be protected. I know it, and assessed it, and decided its not decisive for me. The thing weighs 27 kg anyway, so you do not carry it around. Plus 18 kg solar panels.
