SMA — inverter efficiency loss
SMA inverters have a typical lifespan of 15 years. As with any inverter, efficiency loss and component degradation are expected as the unit ages. Watch for error codes, unexpected shutdowns, and output below rated capacity.
Inverter efficiency loss is a known issue for SMA inverters. This doesn't mean it will affect your system — but it's worth monitoring.
Inverter efficiency loss details
Degradation or malfunction in the inverter reducing DC-to-AC conversion efficiency. Often indicated by error codes or unexpected shutdowns.
Self-check tip:
Check your inverter display for error codes or red/amber warning lights. Compare current output to the inverter's rated capacity.
