A powerful 960W solar charging system with an 800Ah AGM battery bank and battery monitor give this motorhome energy independence. When parked for long periods, three of the 160W solar panels can be tilted toward the south to maximize solar production. The Magnum BMK (Battery Monitor Kit) uses a shunt to measure current and communicates battery status to the existing ME-RC50 inverter/charger monitor. The Victron charge controller in the system core conveys solar charging status to a smart phone. Unless these clients need to run their air conditioner for several hours, they won’t have to worry about plugging into shore power.
