Emiter EM-HWM1-SZR ATS Board (Huawei M1, IP65)

The Emiter EM-HWM1-SZR automatic transfer switch (ATS) board is designed to work with Huawei SUN2000 M1 series three-phase inverters. The device ensures a continuous power supply to single-phase backup loads during normal grid operation and in the event of a grid failure.

The Emiter EM-HWM1-SZR connection board is a solution dedicated exclusively to Huawei SUN2000 hybrid inverters with a power range of 3 to 10 kW. The integrated switching automation guarantees power supply to backup circuits from an energy storage system or PV generator with a switching time of approximately 2 seconds. Backup load protection is provided by a residual current breaker with overcurrent protection (RCBO B16 30 mA). The enclosure design ensures an IP65 protection rating, allowing for safe installation in diverse environmental conditions.
