Question:
My rig came with a GoPower 200 Watt solar panel and a GP-MMPT-10 Controller. My battery pack is the 200Amp Hour Lithium Reliable Power System. Since I will be solely boondocking, year-round, Id like to bulk up my solar system. My roof has space for an additional 200 Watt panel. Will I need to upgrade to the GP-MMPT-30 Controller or the GP-MMPT-60?

Hey Carly, thanks for all of the information. Since you're only adding another 200 watt solar panel with the Go Power Overlander Expansion Kit item # 34282182, all you need is the 30 amp Go Power MPPT Solar Charge Controller item # GP32QR.
