Expert guide to RV 12V DC electrical systems. Covers batteries, wiring, voltage monitoring, and system upgrades.
Expert guide to RV 12V DC electrical systems. Covers batteries, wiring, voltage monitoring, and system upgrades.
Master your RV electrical system from house batteries to shore power. Covers 12V DC, 120V AC, inverters, and charging.
Troubleshoot house batteries dying while on 50 amp shore power. Diagnose converter, breakers, and connections to restore proper charging.
Keep your RV generator running reliably with this comprehensive maintenance and troubleshooting guide for Onan, Generac, and Cummins units.
When your RV converter runs but won't charge batteries, the issue is usually a faulty converter charging section, blown fuse, or bad battery connections. Start by checking the DC fuses and testing voltage output from the converter.
Most RV heat pumps draw 12-16 amps when running, well within your 30-amp service capacity. However, you'll need to manage other electrical loads to avoid tripping breakers when the heat pump cycles on.
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.
Essential guide for Ford E-Series Class C motorhome chassis covering suspension, maintenance, and common issues.
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.
Underhood generators and idling work but check local idle regulations. Extended idling wastes fuel and causes engine wear. Solar, generators, or DC-DC chargers are better long-term solutions.
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.
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.
When your Dometic RV fridge ignites perfectly on AUTO but fails when manually switched to gas mode, the issue is typically a faulty ignition control module or loose wiring connections. The control board may be sending conflicting signals between manual and automatic operation modes.
Your Dometic 12V compressor refrigerator likely isn't getting adequate power from your batteries. Check battery voltage under load, inspect connections for corrosion, and ensure your battery bank can handle the high amp draw required for the compressor.
