If you intend to charge an EV with a standalone (off grid) or emergency backup power solar system. It's important to consider the technology that's used in the inverter. High frequency, transformerless inverters provide a much lower surge capacity and a shorter life expectancy than heavy duty, low frequency, transformer-based inverters. Additionally. high frequency, transformerless inverters do not provide any galvanic isolation between its DC boost stage circuitry and its AC output which can allow high amperage DC current to pass through to your EV's onboard charger and damage it. You may be able to use a high frequency inverter to charge an EV short term, but it would just a matter of time before the MOSFETs or IGBTs in this inverter fail and you can kiss your EV's onboard charger goodbye. A much better and safer choice if you want to charge your EV with solar is to use an inverter or power station that uses low frequency, transformer-based technology in its design. Low frequency inverters can handle high surge loads for at least 3x their continuous rated capacity and they can do this repeatedly, without sustaining damages to their MOSFET transistors, for minutes, rather than the milliseconds that a high frequency inverter offers. And because low frequency inverters use a transformer, they provide galvanic isolation which protects your EV's charger. That's why the big-name brand inverter manufacturers like Schneider Electric, Outback Power, Sigineer Power, Magnum Energy and Victron Energy and others, all use a low frequency topology in their design.
In Australia where we only drive 33km on average per day it's easy with many sunny days. One good day of solar can power an EV for at least five days of driving. 5kWx6 hours gives 30kWh. 15kW/100km(best case). Average daily drive of 33.2km gives you 6 days of driving.
