I have an idea, that I have no idea if it would work. We have an off grid power system, but we are not completely off grid yet. We built a tractor shed which has 72 12 volt solar panels on in banks of 4 for a 48 volt system (we bought the panels used for $10 each). There are four panels in the system that are not producing enough energy, so we shut down that group as they were dragging down the production of all the other banks of panels. My husband came up with the idea of bringing a wire down from them and wiring them to plug into the golf cart for charging, using the charge controller that is already on the golf cart to regulate the power to the batteries. We may end up using the plug in end of the AC charger so we can plug it directly into the system when we park it. My question is, can we use it dual purpose? Can we wire a light into the wiring going down to the golf cart that would pull power from the golf cart batteries as long as it is plugged in? We need a light for the tractor shed for working at night. It would be totally cool if that was an option.

Absolutely Sherry, id love to help If you have specifics.

You can use appropriate wire and a quick release like an anderson connector to connect to a dc sub panel for distribution to lighting or a 36v inverter inside the shed. or you could mount the inverter onboard the cart and have a mobile power supply for say, an electric chainsaw or other use and just use a male-male extension cord to plug mobile inverter power into an ordinary household outlet that is the feed in point for a couple lights and an outlet or two, wired as any other building would be.

If you use dc direct, shop for rv H-4 led replacements that will tolerate 36 volt down to 24v nominal. Great lumens and efficiency at a low cost the dc way. Of course there will be a quick release for pv and one for dc or ac power to the building electric in both cases
