GoodWe error 28ETU: DSP communication failure
GoodWe inverter alarm 28ETU usually indicates a communication fault between the inverter’s DSP components. This can happen due to intermittent external factors such as magnetic interference or may point to a faulty internal component.
When this occurs, the inverter may fail to operate correctly or report status inaccurately.
