FoxESS EPS-BOX PRO Three-Phase Backup Box 63 A for H3 Inverters
The FoxESS EPS-BOX PRO is the enhanced version of the three-phase transfer switchgear for the emergency power supply function in systems with FoxESS H3, AIO H3 and H3 Smart hybrid inverters. Compared with the standard version it handles up to 63 A per phase both on the input from the inverter and on the output to the priority loads, and is therefore suitable for large homes and small commercial users with high backup power.
It is housed in a sturdy metal enclosure with IP65 protection rating, for wall installation indoors or outdoors, with natural convection cooling. It integrates an RS-485 communication interface for connecting the energy meter, which is required to manage the exchange with the grid and self-consumption. In the event of a blackout it isolates the system from the grid and keeps the loads connected to the backup output supplied.
