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.
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.
For the ‘To 2+*3’, ‘To 5+*5’, ‘To 5+*10’, ‘To 5+*15’ ‘To 5+*20’ years extended warranty, it includes 2 to 5 years limited warranty which comes with the inverter product by default and 3 to 20 years extended warranty which covers hardware costs (including spare parts or unit to fix the issue at GOODWE’s sole discretion), excluding any other costs.
2 years *limited warranty for off-grid inverters including EO series. 25 years limited warranty for RSD 2.0 Receiver and 10 years limited warranty for RSD 2.0 Transmitter-PLC. 5 years limited warranty for accessory product including ABD, MPD, ATD, STS.
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.
The warranty terms vary for different types of inverters. For example, string inverters have a 12 to 20-year warranty whereas microinverters and power optimizers come with a 25-year warranty.
