RV converter not charging batteries? We test output voltage, replace diode boards, and upgrade to modern multi-stage converters. Mobile service in SW Florida.

Your RV converter takes 120V AC shore power and converts it to 12V DC to charge batteries and power your 12V systems. A failing converter means dead batteries, dim lights, and non-functional 12V accessories. Sun Coast RV Service diagnoses converter issues quickly with precision voltage testing.
Older single-stage converters can overcharge and boil batteries. We often recommend upgrading to Progressive Dynamics or WFCO multi-stage converters that provide proper bulk, absorption, and float charging. This extends battery life significantly, especially important for Florida's heat which already stresses batteries.
