We will keep down time to a minimum by shipping a replacement device as soon as possible, generally the same day as your call or online request. Should our inverter need replacement, we will provide you with an upgrade containing the latest technology. We will even exchange discontinued inverters with a new model where technically feasible. SMA technology is continuously evolving. With our unique future-proof guarantee, your customer can be assured his or her replacement device will perform as well as, or better than, when it was first installed.


If your eligible inverter is within warranty, it will be replaced at no cost. The SB1100U, SWR1800U, SWR2100U, SWR2500U, SB3300U, SB3800U, and SB6000U are currently eligible for the SMA upgrade program. SMA will even dispose of your old inverter properly in order to comply with electronic waste disposal laws.
