Our previous electric car was a VW Golf converted to electric with a 120 volt battery. I have 5 PV panels arranged in series that I could plug directly into the car and charge it directly from the PVs as the output voltage of the panels fairly well matched the charging curve of the batteries--as the battery voltage increased, the current output of the PVs dropped significantly, down to an allowable trickle charge rate for the batteries. However, the microinverters on the other PVs that I have allow them to produce a higher wattage output because of the MPPT function of the inverters, and they are also giving e usable power whenever the sun is shining, not just when the car was plugged in, as the other inverters did. I came to the conclusion that it was more efficient overall to reconnect the 5 panels that had been used to charge the Golf, using microinverters, and have them feed into our home system also, and the end result, even considering inverter losses and charger losses, would overall be more efficient. Still need to find time to do that, though.
