RV Inverter Repair in Dillsburg, PA
No 120-volt power off battery, or an inverter that keeps faulting.
Mobile service
The inverter turns battery power into household power for your outlets, television, and residential refrigerator. When it quits, the coach still works on shore power, so people often do not notice until they are off the grid.
Most inverter calls come down to four things: low battery voltage under load, undersized or corroded DC cabling causing a voltage drop, a failed transfer relay so the unit never switches sources, or a genuinely dead unit. Overload shutdowns from running an air conditioner or a hair dryer through an inverter that was never sized for it are common too.
We test the DC side before we condemn the inverter, then repair, reconfigure, or replace and re-cable to the correct gauge and fuse rating.
Signs you need this
- No power at the inverter-fed outlets while off shore power
