Solar Inverter Diagnose & Repair

Solar Inverter Diagnose & Repair

Solar inverters can stop working for a variety of reasons. Why? Simply put, the generation and transmission of electricity is a complicated business. For a century, this process was standardized as much as possible. Now with solar, we are condensing that huge process down to one location – your home. And every home is different. In many ways, getting a solar inverter to work properly with your solar panels and home is a custom business. Perhaps your home or system (or the two in conjunction with each other!) need the settings on your inverter set to particular parameters. Maybe you have a particularly heavy energy load in your house that throws your AFCI sensor off every time it turns on. The possibilities are endless. And the last thing you want when your inverter is down and your losing money every minute, is someone guessing as to what the problem is. This is when you need a professional trained in a systematic way to determine problems with solar systems – not just someone relying on experience (or their lack thereof!). This is when you need a Solar Service Electrician.

Most inverters have dozens if not hundreds of potential fault codes describing different scenarios where the inverter has to temporarily stop working for one reason or another. The trick is being able to understand the fault code and start working to remove the problem and the code. This is a complicated and often times tedious process that usually involves the manufacturer. Whoever your solar inverter manufacturer is will normally require an electrician on site taking specific measurements for them in order to nail down the root issue. This is not a task for an unlicensed or inexperienced person. They will be facing hundreds of volts of electricity in the face the entire time. Throughout this process someone trained to systematically diagnose root issues is invaluable. Furthermore, inverter fault codes often emanate from problems on the roof. Here are just a few examples of underlying issues that cause inverters to go into fault mode: power outages, power surges, ground faults, arc faults, lightning storms, high humidity, water in electrical components, blown connections on the roof, software out of date, heavy rain storms, micro-inverter issues, optimizer issues, improperly sized strings, dirty panels, low voltage from solar, high voltage from solar, improper terminations at the inverter, improper terminations on the DC side of the system, critter damage to solar panel wires, and hail damage to solar panels.

Whatever the issue is with your inverter, Solar Service will diagnose it, and repair it one way or another. If it turns out you do need a new inverter or inverter component, we will work with your manufacturer to issue you a new one under your warranty and handle all of the logistical coordination as well as the install.
