4 FAQs about Regarding the warranty regulations for solar inverters

Do solar inverters come with a warranty?

String inverters typically come with 10-12 years of warranty coverage, whereas microinverters and power optimizers are often covered for 25 years. Labor and shipping expenses are generally not included in solar inverter warranties, but some of the strongest brands will cover one or both of these costs.

How long is a power inverter warranty?

Usually, inverter manufacturers offer a standard warranty period of 10 years for string inverters, whereas module-level power electronics (MLPEs) like microinverters or power optimizers offer 25-year warranties. In the case of an extended warranty period, few manufacturers allow you to purchase extra warranty time for their products.

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.

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.
