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.
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.
An inverter beeping three times and shutting off typically indicates low voltage under load, overheating, or overcurrent protection activation. While your batteries show 12.8V at rest, they may drop significantly under load due to poor connections, battery degradation, or undersized wiring.
An E1 error on your MPPT solar controller typically indicates a battery over-voltage condition or wiring fault. This comprehensive guide shows you how to diagnose and fix the issue safely, including when professional help is needed.
A lithium battery showing 20% but not accepting charge typically indicates a BMS protection mode activation. Try disconnecting all power sources for 30 minutes, then reconnect to reset the BMS before checking connections and charging sources.
Most RV solar systems range from 200-800 watts using 12V panels wired in parallel with PWM or MPPT controllers. Wire gauge depends on amperage and distance, with 10-12 AWG typical for most installations.
Dual purpose lithium batteries work for coach use but dedicated deep cycle lithium is better for house banks. Dual purpose compromises between starting and cycling. For RV house batteries, deep cycle LiFePO4 provides better value and cycle life.
Even with disconnect switches engaged, phantom loads and battery self-discharge can drain RV batteries during storage. Installing battery maintainers, using master disconnect switches, and addressing phantom loads will solve this issue.
Your Progressive Dynamics converter needs either a lithium-compatible charge wizard upgrade (PD9160ALV) or complete replacement with a modern lithium-capable charger like the AIMS or Progressive Dynamics PD9200 series.
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.
Low amp charging from solar panels is typically caused by loose connections, incorrect controller settings, or battery issues rather than a bad controller. Start by checking all wiring connections and battery voltage before replacing the charge controller.
LiFePO4 lithium batteries like the Dyness can replace lead acid batteries, but you'll likely need to upgrade your converter/charger to a lithium-compatible model. The BMS protects the battery from overcharging and provides longer life with faster charging.
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.
Install low voltage disconnect relay in line feeding Ecoflow alternator charger. Victron Battery Protect or similar cuts power at set voltage. Set disconnect at 12.8V for LiFePO4 to stop at about 20% remaining capacity.
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.
