PV Inverter Warranty

What is a solar inverter warranty?

Here’s a breakdown of solar inverter warranties by major manufacturers: When you choose Enphase microinverters, you’re backed by the Enphase warranty, which gives you 25 years of coverage—matching the lifespan of most solar panels. That means your entire solar system is protected long-term.

How long do inverter warranties last?

Inverter warranties vary by manufacturer and inverter type. String inverters typically come with 10-12 years of warranty coverage, whereas microinverters and power optimizers are often covered for 25 years.

Do inverters have extended warranties?

Some manufacturers offer extended warranties for an additional cost, but coverage varies. While a standard inverter warranty typically covers defects and failures, extended warranties may extend coverage for parts, but not always labor or service costs. Some manufacturers provide refurbished replacements instead of new units.

Does a string inverter have a warranty?

Most string inverters come with a 5- to 12-year warranty, though some manufacturers offer extended warranty options for added protection. Since a string inverter failure affects multiple solar panels at once, it can cause significant system downtime. Some warranties cover replacement costs, but labor and shipping fees may not always be included.

Does moving a solar inverter void a warranty?

This isn't common, but remember that moving your equipment and re-installing solar inverters in a new location will likely void your warranty. Look for mentions of wires and cables in your terms. Many companies don't provide warranty coverage for these – even if they supply that equipment.

Do inverter warranties cover labor?

Parts vs. labor: Many inverter warranties cover only the replacement part, meaning you’ll have to pay out of pocket for labor and service fees. Some extended warranties may include labor coverage, reducing your overall repair costs.
