The standard product warranty of SolarEdge inverters can be extended to 20 or 25 years, depending on the inverter model. The RMA process is quick and generally SolarEdge will ship a replacement device within 48 hours, provided the reported defect is covered by the product warranty. The warranty extension is available after a one-time payment and must be purchased from SolarEdge within 24 months of inverter shipment. The inverter warranty extension only applies to the inverter itself and does not apply to the built-in communication modules.
