Emiter EM-HWL1-SZR ATS Panel (1-phase, Huawei L1)

The Emiter EM-HWL1-SZR Automatic Transfer Switch (ATS) panel is designed to work with single-phase Huawei L1 series inverters. The device provides an uninterrupted power supply to backup loads, utilizing energy stored in the battery system or from ongoing photovoltaic module production.

The Emiter EM-HWL1-SZR ATS connection panel enables the power supply of a dedicated single-phase backup circuit in photovoltaic installations. It is fully compatible with Huawei SUN2000 inverters in the power range of 2 to 3.68 kW. The switching automation guarantees the continuous operation of connected loads during both standard grid operation and grid failures. The IP65 enclosure protects internal components from the negative effects of outdoor conditions.

Key features
