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.
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.
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.
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.
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.
Protect alternator from lithium battery high current draw using DC-DC charger for current limiting or temperature-controlled relay. DC-DC charger is best solution. Direct connection without protection risks alternator failure.
For three 400W panels (1200W total), you'll need an 80-100 amp MPPT controller. Calculate by dividing total wattage by battery voltage, then add 25% safety margin.
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.
A lithium battery manager relay protects lithium batteries from overcharging by disconnecting them from the alternator when not needed. Installation involves wiring the relay between your alternator/converter and battery bank with proper fusing and control circuits.
Yes, you need a DC-DC charger to safely charge your lithium battery from your truck's alternator. Installing one between your truck's charge line and battery will prevent alternator damage and provide optimal lithium charging.
12V fridges draw 3-6 amps and your tow vehicle should provide enough charging through 7-way connector. Check voltage at trailer while towing - should see 13.5V+ if charging properly.
Keep boost switch wiring separate from DC-DC charger circuit. Add dedicated chassis battery charger or use DC-DC second output for trickle charging. Boost switch remains for emergency use.
