I have a Genasun 36 volt charger on my golf cart boosting from a Kyosera 245 panel (26.9vm 29 voc) on the roof of the cart. Works perfectly. I'm starting year 12 running this rig with solar only. I originally had 3 85 watt Sunwize panels on it and about 3 years ago I decided I didn't like the water dripping between the panels when it rained and had an orphan 245 so order the Genesun which lives under the seat next to the batteries.
