Circuit board replacement for Magnum Energy MS Series inverter/chargers. The FET (Field Effect Transistor) board enables the low-frequency topology that converts DC battery power into pure sine wave AC output for RV applications. Designed to work seamlessly with MS2812 and compatible units, this board handles the core switching and voltage conversion in mobile, backup, and off-grid power systems.

Replace if your inverter exhibits intermittent output, humming, or failure to charge. Installation requires disconnecting battery terminals and unmounting the old board.

• Compatibility: MS2812 Power Inverter
• Topology: Low frequency
• Efficiency rating: 90%
• 3-year manufacturer warranty
