4 FAQs about How long is the warranty period of 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.

How long does a solar inverter last?

While the warranty terms for inverters themselves vary, warranties for communications equipment (which allow the inverter to connect to other devices like solar panels and battery systems) are typically capped at 5 years for both string inverters and microinverters.

What factors affect the warranty period of an inverter?

Inverter Type: The warranty period is influenced by the type of technology used. For instance, microinverters have longer warranties when compared to string inverters.
