Inverter & Optimizer Replacement

The inverter plays a central role in converting the electricity produced by a solar array into power your home can use. When an inverter develops an error, malfunctions, or goes offline, solar production is directly affected. Module-level optimizers can also reduce production when an individual unit stops operating correctly.

Rehab Solar provides inverter and optimizer diagnosis and replacement throughout San Diego County. We work with your existing solar equipment, the inverter software, and the manufacturer to find the source of the problem and identify the right replacement component when replacement is needed.

Diagnosing Inverter and Optimizer Problems

An inverter problem may appear as an error message, an offline system, irregular production, or missing production altogether. Optimizer problems can be less obvious, because the rest of the solar system keeps operating while the affected panel produces less than expected.

Because several solar issues can create similar symptoms, we first confirm which component is responsible. That may include reviewing monitoring information, inverter reporting, system errors, and the operation of related equipment. If you don’t yet know what is causing your solar problem, our system troubleshooting service is the best place to begin.

Replacing Failed Solar Equipment

Once the problem is diagnosed, Rehab Solar helps file for replacement components and performs the inverter or optimizer replacement on site. After the new component is installed and connected, our technician checks the system to confirm it is fully operational.

• Review inverter errors and available system monitoring information.
• Identify whether an inverter, optimizer, or another issue is causing the problem.
• Determine the correct replacement component.
• Remove and replace the affected inverter or optimizer.
• Check system operation after the replacement is complete.

If your system has other damaged or worn components beyond the inverter or optimizers, visit our maintenance and repair page. For general information about how solar energy systems work, the U.S. Department of Energy is a helpful resource.
