Freedom 20D losing one circuit after overload indicates internal breaker or output relay failure. Internal breakers may look fine but fail closed. Open unit to locate and test internal protection devices. Replacement parts available through Xantrex or specialty suppliers.
The Magnum MS 2812 is only a 30A charger, not 50A, despite being a quality unit. For true 50A charging, consider the Progressive Dynamics PD9260C or Aims 3000W units under $1000, or bite the bullet on a higher-end Victron or Magnum 50A model.
While Xantrex no longer repairs the RV3012GS inverter, several third-party companies specialize in rebuilding these units. Alternative solutions include compatible inverters from AIMS Power, Go Power, and Magnum Energy that don't require complete system overhauls.
Replace failing MS2012 with Victron MultiPlus, Xantrex Freedom XC, or larger Magnum model. Check battery voltage under load first - weak batteries cause similar symptoms.
Generator shutdown causes voltage drop that trips inverter into fault. Common with AGS systems. Solutions include adjusting transfer switch timing, inverter sensitivity settings, or generator governor. May need to reset inverter after each AGS cycle.
