warnings and precautions may lead to device malfunction or damage.

3. Introduction
3.1 Basic Instruction
The Afore AF-DH series 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.

Introduction 04
The Time of Use mode is designed to reward customers who do their part to
reduce demand on the electric grid, particularly during peak usage periods. Use
most of your electricity from PV energy and during off-peak time periods, and you
could significantly lower your monthly bill.
When select 0 W under P_Feed menu, the inverter will export zero energy to the
grid.
When select xx W under P_Feed menu, the inverter will export customized
energy to the grid.
