This is not UL so it has to be off grid. That said still good value if you don't know where to start. Suitable for maybe a 600 sq ft cabin.

Yes! But I would guess only slowly or in a pinch.

A 120v EV adapter will pull 1000-1200w, which this would easily feed for hours. Which you'll need as it might take 50 hours to charge the normal 20->80%. In common ev terms that's about 3 miles per hour of sunlight. If you drive <15 miles per day it should work great!

240v Level 2 chargers pull 7-11kW. You'd probably want 13-15kW of panels if you don't live at a mid latitude in a flat field to push that.

I'm in NC with an EV capacity of 80kWh, and this week 16kW of panels on my roof just barely kept up with running a 7kW EV charger and modest household loads. In the full day they made about 60kWh, but the problem is modulating the charger to get the best out of that.

Can't you grid tie this to charge from the grid and connect NEM 14-50 to it for level 2?

This is a split phase inverter so you'll get 240vac. 20kwh batteries+solar will easily get you L2 rates.

If you are interested in this combo, make sure that you understand how the software works for the inverter. This is a ~$1000 inverter and you have a few options for that kind of money. I built an ecoworthy set (batteries+inverter). Manually the set works for me but the software/app does not work with the inverter properly. The inverter is the 5000w all in one (the little brother of this 10000w all in one). Many people were suggesting to pay third party software called "solar assistant" which is extra cost and requires raspberry pi.

Make sure you know what you are getting into before buying the combo. Their batteries work fine.

Mechanically yes, but without UL or other common listings it may be harder to pass inspection for grid tie and/or net metering.

I was also evaluating this based on my panels in NC latitudes and needing to charge a vehicle reliably 365 days/year. I get 2MWh in a summer month that sinks to 750kWh in the winter. You can approximate your delta with a solar irradiance calculator online.

If you're at a latitude where you get close to nominal year round with minimal losses to wires or cold batteries in the garage this is perfect. For me and my EV shooting for full off grid I'm not sure it's quite enough.

Smaller car, closer to nominal output, this can be a great setup or perfect for somewhere you have grid power to back it up

Can this split phase inverter charge 120AC from outlet and output 240V NEMA 14-50?

Yeah but an EV battery is ~65 Kilowatt hours and this is 10 Kilowatt hours. So we are talking less than a quarter tank on backup power
