Always using the cheaper energy from the utility grid, and saving money everyday. 

Off-peak hour:  charge from the gird
Peak hour:  discharge to the loads

When you choose load shifting mode, you can use cheaper power by Copia. The Copia inverter will charge battery at off-peak hour when the electricity price is low, and the discharge to meet your home energy needs at peak hour when the electricity price is how. In this case, you can always use the power at lower price.
Still,  the EPS will work when there is an outage.
