Page 6: Introduction
Introduction 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. -
Page 7: Time Of Use
Introduction Note: Advance Setting 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. 3.2.2 Time of Use 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. - Page 8 Introduction Note: After select AC charge, the AC will also charge the battery when the PV is low or no PV. B. Forced discharge 4 periods of time discharge setting Energy flow: Battery and PV → Load → Grid C. Forbidden Discharge 4 periods of time discharge setting, the battery will be charged firstly.
