Solar Inverter Repair in Peoria, AZ

Solar Inverter Repair comes up often in Peoria, and the reason is simple: the inverter does the hard electrical work, often mounted on a garage wall or the side of the house in full afternoon sun. Panels have no moving parts and can last decades. The inverter converts their direct current into alternating current every sunny hour, and it is packed with electronics that age faster when they run hot.

What fails inside an inverter

Most string inverters use electrolytic capacitors, and those have a life expectancy on the order of a decade. Heat shortens it. Larger inverters also use cooling fans that pull in dust, and in the West Valley that dust is never far away. When a part gives out, you may see an error code, a red or orange status light, a blank display, or an inverter that runs in the morning and shuts down every afternoon when it gets hot.

Inverter types we work on

• String inverters: one central unit, usually on an outside wall, that handles a string of panels
• String inverters with optimizers: a central inverter paired with small optimizers under each panel, common on SolarEdge systems
• Hybrid inverters: units that also manage a home battery

If your system uses microinverters under every panel, see our microinverter page. That is a different repair.

Repair or replace?

Some inverter problems are fixable without new hardware: a tripped AC breaker, a blown fuse in the combiner, a loose terminal, a failed communication card or outdated firmware. Others mean the power electronics inside have failed. For most residential string inverters, that means replacing the whole unit rather than opening up the circuit boards.

Before we price a new inverter, we look for the warranty. String inverters often carry 5 to 10 years from the manufacturer, and some owners bought extensions. If the date on the label or the paperwork says it is covered, we help you start a claim with the manufacturer.

When the replacement is a different model

If the original inverter is discontinued, the new one has to match the array's voltage and current, fit the existing wiring and meet current electrical code. Changing the inverter model can need a City of Peoria electrical permit and an update to your interconnection agreement with APS or SRP. Check with the city for your address; any permit step belongs on the written estimate.

Where you place the new one matters

If the old inverter sat on a west-facing wall in direct sun, we talk with you about moving the replacement to a shaded wall or adding a shade cover where the manufacturer allows it. Running cooler protects the electronics and reduces heat-related shutdowns on the hottest afternoons.

What it costs you to wait

A dead string inverter means the entire array produces nothing. Under the export rules APS and SRP use today, every kilowatt-hour your panels do not make is one you buy back from the utility at retail. A summer without a working inverter adds up quickly.
