Liebert ESU 3 Phase
Liebert ESU is single / three phase output, bi-directional inverter system. ESU operates in parallel with the grid utility. Solar Photovoltaic panels convert solar energy into electrical energy as DC power. This DC power is used to charge the batteries through a charge controller and also used for the load through inverter. Additional energy is exported to the grid.
