It is a high-voltage DC combiner box that merges up to 3 battery towers into one protected DC output for battery-to-inverter ESS wiring.
The supplied datasheet lists 750 V DC maximum operating voltage, 60 A rated current, 50 A maximum output current, and 6 kV impulse voltage.
The supplied datasheet does not clearly state an IP rating. Outdoor or exposed installation suitability should therefore be confirmed before use.
