Solar charger fuse ? On/off switch? April 01, 2023, 05:54:08 pm 2002 RB '''Does anyone know if there is an on/off or fuse for the old HELIOTROPE RV-30 charge controller. 'Long story short", the controller was showing 16 volts..bouncing to 17 (Battery Volts) in the sun. I don't keep the LDaze parked in the sun..just happened to be there briefly...so I moved it out of the sun immediately. Disconnected controller and in the process created some sparks. Now the new controller will show nothing and the battery+/- show nothing with a multimeter on it. The multi shows about 20 to 21 volts when connected to PV -/+. Not having bought this LD new (no owners manual) is there a fuse I have blown? Help appreciated.

There should be an added, inline fuse, usually with a tape label with"Solar" on it.Amazon.com: MCIGICM 12 AWG Inline Fuse Holder with 30A ATC/ATO Blade Fuse, 5...Larry As an Amazon Associate Lazy Daze Owners' Group earns from qualifying purchases.

Unfortunately, I didn't catch on until it had ruined an expensive set of batteries.

Re: Solar charger fuse ? On/off switch? Reply #5 – April 01, 2023, 08:48:39 pm The power center with the brown fold down cover, has 110VAC circuit breakers on the left hand half and 12 DC. fuses on the right hand side. In the RB floorplan near the oven I think. Others have posted pictures and the added loose solar fuse is adjacent to the hard in place fuses. Battery Disconnect Switch and Solar panel fuse Your older 2002, if it hasn't been upgraded, will look a little different than this picture. You have a Parallax converter. This picture is of a newer version with the two green 30A fuses. RonB

The 30-amp Buss circuit breaker is also used as a switch when working on the electric system.Larry
