How Would Go Power Solar AE-6 Wire to 2025 Grand Design 337RLS
Updated 10/27/2025 | Published 03/25/2025
Question:
I’m installing 3 60 Amp MPPT solar controllers and panels into my 2025 Grand Design 337RLS. I’m confused about the battery +/- and the load +/-. My RV came with one 60 Amp MPPT, but I’m replacing it with 3 GoPower MPPT’s. I know to connect the RS485 connectors, and to do the main/slave configuration. My RV has a circuit board that has 3 inputs labeled ‘solar prep”. The circuit board has one battery input, one converter/charger input, and the 3 solar prep inputs. I don’t want to send the power to the same circuit board 2 ways, and overload something . Do I take the load +/- to the circuit board, and the battery +/- to the battery?

Hey Guy, so the solar chargers that come with the Go Power Solar AE-6 All Electric System with 3 MPPT Solar Controllers # 342-75011 are designed to run straight to the battery. The solar prep circuits on your converter are probably solar chargers themselves so you would not need to utilize them and instead would just want to route the Go Power chargers straight to the batteries.
