Most carts run at 48vdc these days. They either have eight 6 volt
batteries, or six 8 v batteries. I would think that would make a good
match for power backup with a 4kw range inverter like the Magnum MS4448.

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.

Every now and then I get questions here in the land of hurricanes and golf
courses about using golf carts as the battery bank for a permanently mounted
grid-tie home PV system in a backup scenario. 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.
The idea is becoming more popular as people hear about using EVs for home
backup. I'd like to get ahead of it and maybe even offer a solution that's
safe, legal, and functional.
