1. ESS introduction & features
When using a grid-tie inverter, it is connected to the AC output as well. When grid power is available, the battery will be charged with power from both the grid and the PV. Loads are powered from PV when that power source is available. Feed-in is optional and can be enabled or disabled depending on local regulations.
