Single-Phase ATS Switchgear 16 A for Huawei SUN2000 L1 Hybrid Inverter
Single-phase ATS (Automatic Transfer Switch) switchgear for photovoltaic systems with storage, designed for the single-phase hybrid inverters of the L1 series (Huawei SUN2000-2KTL…3.68KTL-L1). In the event of a grid failure it automatically switches the supply of the priority loads over to the backup output of the inverter, powered by the battery and the photovoltaic generator, and restores the grid connection when the grid returns.
Switching takes about 2 seconds by means of two interlocked contactors (25 A K1/K2) that guarantee double separation from the grid during island operation, as required by the connection rules. The backup circuit is protected by a B16 30 mA RCBO, for a maximum output current of 16 A (about 3.68 kW). The switchgear has an IP65 protection rating and is suitable for TN-S and TN-C-S systems.
Key features
Automatic switching in about 2 secondsWhen the grid fails the switchgear transfers the priority loads to the backup output of the inverter and returns them to the grid once it is restored, without any manual intervention.
Double separation from the gridThe two interlocked 25 A K1/K2 contactors guarantee separation on both conductors during island operation.
B16 30 mA RCBO protectionThe backup circuit is protected by a residual current circuit breaker with overcurrent protection, curve B, 16 A and a 30 mA residual current threshold.
Up to 16 A outputMaximum backup current 16 A at 230 V, equal to about 3.68 kW of priority loads that can be supplied when the grid is absent.
IP65 wall-mounted enclosureIP65 protection rating, wall mounting, 3 × M20 and 1 × M16 cable glands, terminals up to 6 mm² for inverter, grid, backup and communication.
Compatible with TN-S and TN-C-S systemsDesigned to operate on TN-S and TN-C-S distribution systems, with an operating temperature from -20 to +40 °C.
