[RE-wrenches] Golf Cart as temporary off-grid PV

[Nick A Lucchese]

Not sure what the golf cart fleets are these days but decades ago as a youngster I worked at a course where all the EZ-GO’s were 36v nominal with all Trojan T-105’s. Also uncertain if still available or not but years ago the first Cybo inverters I purchased were also intended for 36v nominal battery banks. Perhaps George and the team still offer that model. It’s obviously a different type of architecture and I didn’t have any luck with the 4 amp 36v charger on the inverter’s AC output that was promoted but surely you could figure your means of charging with perhaps a Flexmax or similar. I had some issues with the hot water heater model but the off grid model consistently performed it’s inverting function assuming there was a fan or some sort of resistive or inductive load to keep the inverter awake. The only other 36v inverter I can think of was the Heart Transverter which was a big loss for a few of us.

Best of luck Jason, Nick

Does anyone have any ideas on a good way to do something like this? The battery would need to be able to be unplugged of course (not under load I hope!) It's mostly DIY'ers trying to cobble together a solution for a small critical load panel for their home.
