Help - MPPT 25a Charge Controller

[JArcher2023]

Tonight I removed my battery on my 2022 21BHE and was replacing my one battery with two batteries running parallel. I hooked the batteries up and now the charge/fault LED indicator will not light up, the sealed battery LED will light up for about 30 seconds and go off. Before I change batteries it worked fine. Just because it’s dark out they LED’s should still light up correct?

What is the brand and model of your MPPT charger?

Verify your connection. Make sure positive and negatives are connected properly.

Brand is a Furrion MPPT 25a.

Here are some suggestions for trying to get that controller back on line.

1. Double check that all wires are installed in the correct location and are tight.
2. Make sure the RV battery disconnect is turned on. The battery disconnect may or may not be wired into your circuitry depending on build specifications.
3. Find all fuses, circuit breakers, and/or switches in your solar charging system's wiring and make sure they are functioning properly.
4. If you still haven't found the issue, disable the solar panel connection/charging by covering the panels with cardboard, working at night, or turning off a disconnect switch. Then disconnect the MPPT battery connections. Then reconnect the battery connections and re-energize the panels. (This is a hard reboot).

Hey JArcher2023, So the lights do all go out at night. I found this out this summer. Once the controller has no solar energy input, it goes into EcoMode. It is in the manual but as usual with Furrion it is poorly explained. As you experienced, as soon as the controller as solar energy input again it turns on. It is a feature to save on the energy, as to keep on it would need to draw from the battery.
