3. Introduction
3.1 Basic Instruction
The VTAC hybrid inverters are designed to increase energy independence for
homeowners. Energy management is based on time-of-use and demand charge
rate structures, significantly reduce the amount of energy purchased from the
public grid and optimize self-consumption.

The Self-Use mode is for the regions with low feed-in tariff and high electricity
prices. The energy produced by the PV system is used to optimize
self-consumption needs. The excess energy is used to recharge the batteries,
any remaining excess is then exported to the grid.
