GEM Electric Cars - Solar Charging

I have a 2002 GEM e4 and would like to charge it with PV Solar Panels.
I have an 80vDC, 272amp solar source.
This should be adequate for the 72v GEM system.
To charge, I’m projecting that I would plug directly to the Control and not go through an inverter to convert solar DC to AC to plug into the GEM inverter that converts AC to DC.
Any help out there. Thanks.
