edit: yep and Genasun makes it : https://genasun.com/all-products/sol...st-controller/
Though still with the rather slow charging factor we have mentioned. About the only use is as a slight range extender for a cart by mounting a PV module on the cart.Last edited by ButchDeal; 04-26-2018, 04:47 PM.OutBack FP1 w/ CS6P-250P http://bit.ly/1Sg5VNHComment

Yes sir Genasun GVB8, but it requires a 24 volt panel to charge a 48 volt battery. Now that may sound great to folks, but at the end of the day is not much help at all. A golf cart efficiency is roughly 150 wh/mile. A 100 watt panel mounted on a cat pointing straight up on a bright sunny day out in the sun all day from sun up to sunset at best can only generate 300 watt hours usable. A whopping 1 to 2 mile range extender. A gold cart battery is 48 volts @ 225 AH or 10.8 Kwh so adding 300 wh is like peeing on a forest fire.Comment

I charge my 36 volt golf cart from the genason Paid $186 2 years ago It is slower than the 120 V golf cart Charger But for me I am off grid it works just fineComment

You are exactly right I gave up golfing a long time ago Gets my wife and I around R5 acres with no issuesComment

Sounds like something I plan on for our 2.5 acres. Although for me it would be cheaper just to charge the carts batteries from the grid instead of building a solar rig.Comment

I am trying to design an off-grid golf cart charging station. I am using PVsyst to help me design the system. My preference is not to add batteries to the system
The load:
(8) 6v battery trojan t-105
It connects to 220v AC source
The car has an onboard AC/DC charger
I will be using around 12 PV 300 watt solar panel and 3kw inverter with AC input range from 120
12 x 300 watt panels = 3600 watts. Plenty to recharge in a few hours like Sun Up to noon depending on how deeply you discharge the batteries. 8 x 6 volt x 225 AH batteries = 10.8 Kwh. Assuming you limit discharge to 50%, you can easily recharge in half a day. All that is required is a 80 Amp MPPT Charge Controller. You would connect the output of the Charge Controller directly to the batteries and bypass the carts built-in charger. It will not hurt the charger.
Question is can you give up the cart for half a day during maximum sun to recharge? If not you are SOL with the above plan.Last edited by Sunking; 05-01-2018, 12:18 AM.MSEE, PEComment
