Collection: Backup Box / ATS

Automatic transfer boards and backup boxes, the accessory that turns a storage installation into a true UPS: a 16A single-phase ATS for the Huawei SUN2000 L1, the three-phase Huawei SmartGuard-63A-T0 Backup Box with EMMA-A02 module, the three-phase SolarEdge Home Backup Interface at 3x100A in IP65 and Sigenergy C&I gateways up to 180kW.

Without this device most hybrid inverters will not feed the house during a power cut: you need a transfer that physically disconnects from the grid within a few milliseconds, otherwise the inverter stays in anti-islanding and shuts down.

They are chosen on the current of the line switched and on the inverter model.
