The RC7-GS inverter charger can properly charge 105Ah AGM batteries using the 125Ah setting, as AGM charging is voltage-based, not capacity-dependent. Generator start issues typically stem from wiring problems or incorrect DIP switch configurations.
Keep your RV generator running reliably with this comprehensive maintenance and troubleshooting guide for Onan, Generac, and Cummins units.
Modern AGS systems are designed to handle starting with AC load. Built-in delay lets generator warm up before transfer switch engages. Old advice about no-load starts applied to older systems. Your AGS setup for pet comfort is fine.
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.
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.
