The Converter/Charger is the heart of your RV's electrical system. Installing a modern multi stage converter is the single most important upgrade you can do for your RV.

Premature converter failures are usually caused by power surges and voltage spikes from RV campgrounds, portable and onboard generators, lightning strikes, etc and the power converter, inverter or transfer switch (if installed) is the first to absorb the surge. We highly recommend protecting your electrical system with a RV Surge Protector For complete protection from ALL adverse power conditions, consider a Power Protection System
