Thank you for the details. We have district heating here and no EV, that makes a big difference! We use about 15MWh of district heating each year but less than 2MWh of electricity. Our house is from the 70s, but have decent insulation, could be better though

I’m curious, do you know how much you use for heating, cooling and the EV? I supposed those are the big differences to my household.

Interesting. They could supply my household for 20 years on a full charge. I’m missing a count on how many households they can supply with sun power during the night. Also how does this hold up vs. kinetic storage? (pumping water uphills) Seen from a global perspective storing power in li-ion seems bonkers, since it would probably drive lithium prices up to a point where it’s no longer economically viable, but ofc. they sit on much of the supply chain over there…

I get what you’re saying, but still… why did they put an OLED screen on it?
- Comment on Can this be charged 5 months ago:
Thank you all for the responses. I ended up ordering a replacement battery, since i intend to sell the unit and don’t want to pass on a ‘pig in a poke’. Had the voltage been a little higher i would probably have attempted to recharge it.

And also: is a depleted battery more likely to short circuit and overheat?
- Comment on Can this be charged 5 months ago:
Thank you for the elaborate response. Does this seem reasonable: Charging voltage 5 * 3,3v = 16,5v, charging current limit 100mA? And then put the whole thing in the garden? Would you take breaks?
