[RE-wrenches] Solar Golf Cart

[Foxfire Energy]

We clutched on LFP batteries because we see temps down to -30-40F.. And avoided large panels thinking smaller panels were more robust and could stack for higher a VOC.

I was going to agree and say going to lithium battery is actually a big boost in efficiency due to the high weight reduction.

Scott direct mounted the 60-cell module and used the Genesun controller that is a boosting controller.

I also did a similar project and I mounted the leftover 60-cell module to the roof with IronRidge XR10 rail to give a bit more compliance over bumpy trails. I also used the Genesun controller.

I love the Vatrer 36V battery, You can get a 48V (51.2V) version as well…

There are other brands of great batteries that drop in… especially if you have a SawzAll.

Has anyone done a conversion with a solar panel to replace the entire roof of a golf cart?

I would love to get some tips on that. I'm surprised a quick search did not bring up a lot of kits.
