# RV Electrical, Solar, and Generator Repair in Chino

> OCRV Center diagnoses and repairs RV electrical systems, installs lithium and solar, and services Onan and Cummins generators across Chino. Electrical diagnostics start around $285 and solar or lithium installs scale with the system.

An electrical gremlin is maddening because the symptom and the cause often sit far apart, a dead outlet tracing back to a corroded ground bays away. We work the 12-volt house side and the 120-volt shore side, chase faults to the component, and install upgrades like lithium and solar that fit how you camp. Chino owners bring electrical work to our Yorba Linda shop.

## 12-volt and 120-volt diagnostics and repair

Coaches run two power worlds and problems cross between them. The 12-volt side feeds lights, pumps, and controls from the house batteries, while the 120-volt side handles outlets and larger loads from shore or generator power through a transfer switch. We test each circuit, find the fault, and repair it rather than swapping parts and hoping.

- 12-volt house circuit diagnostics and repair
- 120-volt shore power and outlet repair
- Transfer switch and shore power troubleshooting
- Converter and charger replacement
- Fuse block, breaker, and wiring repair

## Solar, lithium, and inverter installs

Upgrades only pay off when the system is sized to your use. We install rooftop solar with an MPPT controller, swap tired lead batteries for a lithium bank, and add or replace an inverter so you can run 120-volt loads off the batteries. Every install is wired cleanly and matched to your existing shore and charging setup.

- Lithium house battery bank upgrades
- Inverter and converter install and replacement
- Battery monitor and shunt wiring
- Shore power cord and inlet repair

## Frequently asked questions

### Can you install solar and lithium on my RV?

Yes. We size the system to how you camp, install the panels, MPPT controller, inverter, and lithium bank, and wire it to work with your existing shore and charging power. A good install matches the system to your real power use, not just bolting panels to the roof.

### Why do my RV lights or outlets keep cutting out?

Intermittent 12-volt lights usually trace to a corroded ground or a loose connection, while outlets that drop out often point at the converter, transfer switch, or a tripped breaker. Because the cause can sit far from the symptom, we test the circuit end to end, find the actual fault, and repair it instead of guessing.

### What is the difference between a converter and an inverter?

A converter turns 120-volt shore power into 12-volt to run your house system and charge the batteries, while an inverter does the opposite, turning battery power into 120-volt for outlets and larger loads. Many coaches need both, and we install and repair each.
