The inverter is what changes the current from DC to AC so you can use electricity from the panels to power your home and devices. EV home chargers use AC.

How does a solar panel charge a battery?

With solar panels, we can charge batteries, and batteries usually have 12V, 24V, or 48V input and output voltage. It is the job of the charge controller to produce a 12V DC current that charges the battery. Open circuit 20.88V voltage is the voltage that comes directly from the 36-cell solar panel.
