Some of the RV20 charge controls were made by Specialty Concepts in California ((818)-998-5238) and some were made by GoSolar in Victoria, Canada. If it is a GoSolar version you should throw it away. Shell sold everything they had to us about 5 years ago. We tossed the GoSolar units and sold the Specialty Concepts one at very low prices. If it is a Specialty Concepts unit, it will have a square pot at the bottom of the circuit board on the back. Counter-clockwise lowers the voltage. They were originally set to charge to 14.4 volts. That is safe for most sealed batteries considering there will be some voltage drop in the wiring. There is no feature for equalization to worry about with sealed batteries.

Fellow Wrenches,

Does anyone have a manual for an old Shell Solar RV20 PV charge controller? Or know where I can get a copy. I searched the web without success. I'd like to know if the charge settings are adjustable for sealed batteries.

Thanks,

Randy Brooks
