About six months ago I bought an Anker set - a portable battery pack and some folding panels. A buddy of mine got basically the same thing, but Ecoflow. He lives in a condo, has a balcony, and can hang his panels there to charge the pack; my options are a little more constrained (3 story house with a couple hundred sq ft concrete "yard", with light blocked most hours of the day by the next house.)

I haven't gotten much use out of my set, but his plan was to run his desktop off it, which sounded very doable. All in all probably not quite the same as Germany (I guess their kits don't need a battery or plug into the wall or something).

The idea of large numbers of big lithium battery packs constantly charging or discharging in apartment buildings is a bit scary to me. Perhaps if they are contained in a fire-proof housing?

The good thing is that many of these are lifepo4, which largely mitigates the risk.
