Coralee said We have started a solar/mico hydro golf cart project. It is not finished, but all the parts have been purchased.
both the outback flexmax and the midnite solar classic will support 36 volt charging directly to the cart battery bank. The outback 60 amp would do up to 2400 watts of solar. So 4 strings of 2 panels each of 60 cell 300 watt panels...

I need to know (lots of stuff cause I am just learning this stuff lol) how many watt / voltage panels do I need I thought maybe a 36 volt mppt charge controller with a plug in connector to hook it up to the golf cart (not exactly sure how to do that part either ) and then I plan on hooking up an inverter (how big an inverter would be best also) so I can use my cart as a solar backup generator. Ive been doing alot of research on this and everything out there assumes you want to mount a panel on your roof and use a low watt / voltage panel. Please help Thanks for your time.
bob, you could mount the array on the ground, the charge controller on the cart, a disconnect swith and a connector to the solar feed. Plug into the panels when you need them. The alternative is panels, chargecontroller, seperate batteries, inverter, regular 120 volt charger... going straight to the cart batteries is easier. so a single say 270-300 watt panel on a rack, with one of these units here: https://www.solarevsystems.com/solar-kits/mppt-solar-charge-controller-36v48v

Solar Panels = Battery Bank Capacity / 4 = 8.6KWH/2 = 2.25KW or about 2KW solar array
Amount of solar panels = 2000W/333W = 6 solar panels (each for $250 for 350W)
Charge Controller = 60A (60A x 40V = 2500W)
Now just connect the charge controller to your output of your battery bank that connects to your vehicle
Yeah, but does being a ninja come with a dental plan? And what about this tiny ad?
