Your modified sine wave Xantrex 758 likely caused the hair dryer malfunction due to waveform incompatibility with sensitive electronics. While some devices work fine with modified sine wave inverters, modern residential refrigerators, computers, and electronics require pure sine wave power to prevent damage and ensure proper operation.
Yes, you can remove inverter/charger and install standalone battery charger. Much less expensive than replacement inverter. Check if inverter includes transfer switch - you may need to address that. IOTA or Progressive Dynamics chargers work well.
House battery at 11.2V is critically low. Connect shore power immediately to charge via the Xantrex built-in charger. Investigate why solar and normal charging failed.
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.
Common RV components with red lights include LP detector, CO detector, surge protector, and inverter. Red typically indicates fault or alarm. Check for model numbers to identify and post photo for specific help.
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.
For your 2021 Winnebago View 24D, a Victron MultiPlus 12/2000/80 or 12/3000/120 would be excellent replacements for your fried Xantrex inverter. You'll need to rewire the connections and can ditch the old remote panel for Victron's VictronConnect app monitoring.
