The only one that comes to my mind now is the onboard generator from the Ford F250 hybrid or the F150 Lighting. These go straight from 300-400Vdc In to either 120/240Vac Out. But are CAN controlled, so CAN messages would have be hacked and a dealership to sell you the unit alone. Sent from

Hey Rob.. Hopefully you recover quickly and ready for that EV project. With regards using the 240W solar to charge the HV battery; that may not be that easy if you want to do that Straight DC to DC: - First you will need to have an efficient DC-DC step-up converter from 20-40Vdc into
