Hi,
I’m looking for a cheap electric car. But, I already have a homemade solar panel system that generate ~1kwh, and I have a ~1k5 inverter.
I saw the Dacia Spring, but it charges at 2.3kw. Is there a way to charge it at lower w ?

AFAICT the lowest valid current signal is 6 amps. So by your old-world thinking, the lowest possible charge rate is 1.4kW or 6 amps at 230/240V.
However, you may be able to achieve sub-1kW charge rate thanks to Japan, Taiwan and far-flung former colonies which use 100-120V for small circuits. It depends what your car will tolerate.
6A @ 120V is 720 watts. 8A @ 120V is 960 watts.
However, if you can’t make that work, you can use a small-ish battery for borrow/refill - charge the battery to 70% then turn on the EVSE and charge the car at 1.5 kW (making up the extra 0.5 kW from the battery) until the battery is at 30%, lather rinse repeat. This will produce a very stable “works in all weather” charging experience - on a sunny day it will run 2/3 duty cycle, but on a cloudy day it’ll run 1/4 duty cycle etc. At least one person on this sub has already done it.
