FoxESS EPS-BOX TP V2 Three-Phase Backup Box 32A for H3 Inverters
The FoxESS EPS-BOX TP V2 is the three-phase transfer switchgear that enables the emergency power supply (EPS) function in systems with FoxESS H3 and AIO H3 hybrid inverters. In the event of a grid failure, the box automatically separates the system from the public grid and transfers the priority loads to the backup output of the inverter, then returns them to the grid when the supply is restored.
It is installed on the wall between the meter and the priority load board and handles up to 32A per phase on the EPS side and 25A per phase on the grid input, on 3L/N/PE 230/400V, 50/60Hz systems. The PC+ABS enclosure with IP65 protection rating and natural convection cooling allows it to be used even in harsh environments, in residential and small commercial applications.
