SMA Solar Technology, a German-based company founded in 1981, is a leading global distributor of solar power solutions. Their inverters are highly regarded for reliability, making them popular in the Australian market. This guide will explore the most common error codes of SMA inverters, their causes, and recommended corrective measures. Error Code 101, 102, 103 – Grid Fault Message: The grid voltage or impedance is too high, leading to disconnection from the utility grid. Cause: Check grid voltage within the permissible range. If outside range, contact the grid operator for adjustments. Correction: Ensure proper grid conditions. If a problem persists, contact SMA Service. Error Code 202, 203, 205 – Grid Fault Message: Grid disconnection due to utility grid issues, damaged AC cable, or low grid voltage. Cause: Check circuit breaker, AC cable, and country data settings. Ensure grid voltage is within limits. Correction: Address issues with connections, settings, or contact grid operato
