The Magnum Energy MMS1012-G
 is a 1000-watt, 12-volt pure sine wave inverter with a 50-amp, 4-stage Power Factor Corrected (PFC) battery charger, a 20-amp automatic transfer relay, a built-in GFCI outlet, and a 3-foot AC cord. It is part of the MMS Series and is designed for mobile applications with smaller power needs, such as in RVs, boats, and cabins. Key features Pure sine wave output: This provides clean, stable power suitable for sensitive electronics.
  • Built-in PFC battery charger: The 50-amp, 4-stage charger uses power more efficiently than a standard charger, drawing 25–30% less AC current from a generator.
  • Automatic transfer relay: A 20-amp transfer relay automatically passes power through the inverter when you connect to shore power or a generator.
  • Standard AC connections: The MMS1012-G version features a 3-foot AC plug-in power cord for input and a dual GFCI outlet for AC output. This distinguishes it from the hardwired MMS1012 model.
  • Battery profiles: Using an optional remote control, you can set charging profiles for various battery types, including Lithium Iron Phosphate (LFP), Gel, Flooded, and AGM.
  • Safety features: The inverter includes multiple safety and protection features, such as low/high battery voltage protection, over-temperature protection, and current overload protection.
  • Efficient cooling: Its die-cast aluminum base acts as a heat sink, and it is fan-cooled for superior performance in confined spaces.
  • Mobile-ready: The unit is ETL Listed to UL/cUL 458 for mobile use and has isolated input/output neutrals.
  • Warranty: The MMS series is backed by a two-year parts and labor warranty.
  • Included accessory: A 15-foot battery temperature sensor is included.
