The EPS-Box TP from FoxESS is an additional accessory that can be installed with FoxESS three-phase energy storage systems. The EPS-Box TP is used to automatically disconnect the local power grid from the distributor's network while switching the main circuits to the back-up supply provided by the EPS connector on the unit. The unit is fully unmanned and is powered by either the distribution network or the EPS circuit. It is made up of two disconnectors connected together to switch the circuits connected to it without collision.
