My battery is totally dead, can I somehow get the renogy charger to start charging? The controllers display is dead, my meter shows the panels are putting out substantial power, the RV battery is dead (6V)

The controllers display is dead, my meter shows the panels are putting out substantial power, the RV battery is dead (6V) I believe that the controller will not attempt to charge a battery when it's that depleted. And that's probably a good thing, too. Dumping current into a completely dead battery is risky. And, without enough voltage to run the controller, it can't do its job properly/reliably. You'll probably need to bring the battery voltage up to the minimum specification required by the controller by other means before it will begin charging it. |

Your battery is completely dead, your controller will not bring it back. But....that only means that you need a charger that can bring a "dead battery" back. That will cost about 300.00, I do have one hooked up in my RV, but you can buy a new battery for under that and not let it go dead again. You might be able to take it somewhere, but then they will just try to sell you a new battery. If you go to the new battery route, make sure you get a high AH battery.

Hello Chgray,
Our charge controller do require the battery to have some charge in it to be able to power on and in turn regulate the voltage and charge the battery. I would recommend putting a charge on the battery from an outside source and reconnecting the controller.

Can u not put the panels straight to the battery enough to get some charge and then hook the controller back up?

Can u not put the panels straight to the battery enough to get some charge and then hook the controller back up? yes, the panels will operate at batt voltage, the purpose of a controller is to limit the voltage to avoid overcharging, you should monitor batt voltage if you hook a panel directly to a batt. |

Yea I was thinking about my system that's putting out 80v plus I don't think that would be a good idea?  ? LOL |

it puts out 80v cuz the controller! without one it will match to the batt voltage and waste lots of watts!
so instead of 5A x 80v its 5A x 12v. later 5A x 13 ... you become the controller to disconnect before it gets too hi
