  • Page 6: Introduction

    Introduction 3. Introduction 3.1 Basic Instruction The Afore AF-SLP 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 Introduction Energy flow: PV → Load → Battery → Grid 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.
  • Page 8 Introduction 3.2.4 Maintain The Maintain mode is suitable for situations where the battery capacity is small, and the battery is charged and discharged at the specified power. Warning: Energy flow: The Maintain mode is only PV → Load → Grid → Battery available for some inverter.

  • Page 9: Time Of Use

    Introduction 3.2.6 ExtEms ExtEms mode requires customized external control accessories that can remotely control the operation of the inverter. It is not recommended to use it without professional personnel. 3.2.7 PeakShave In PeakShave mode, the charging and discharging of the battery are controlled by setting the AC power to reduce the peak load of the power grid.
