3. Introduction
3.1 Basic Instruction
The Afore AF-SL-0 AC Coupled 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.

This mode applies to situation that with low feed in subsidy and high electricity
price.
1. Solar energy supply to the local load and charge to the battery first.
2. The excess power export to the public grid.
3. The wind turbines can be connected to the PV.
4. When off gird and the power is lacking, the generator will be turned on
automatically.

Introduction
05
3.2.2 Charging First
Priority: Battery > Load > Grid
This mode applies to situation with frequent power outages. When the public
grid is off, enough energy can be supplied to the local load by the batteries.
Battery will be charged first, and discharge energy for the local load when the
grid is off. It would be charged automatically.

3.2.3 Command charge and discharge
This mode the charging and discharging power operates according to the set
parameters.
Within the power range that the battery can accept, run according to the set
parameters, otherwise run the charge and discharge command according to the
upper and lower limits of the battery.
3.2.4 External EMS dispatch
This mode power of charging and discharging is controlled by external EMS
communication commands, which is suitable for occasions with centralized
EMS.
To meet the power of EMS charging and discharging, the residual energy is fed
back to the grid.
Priority: Battery charge command > Load > Grid

Introduction 06
3.2.5 EPS
3.2.6 Timed charge and discharge
When the grid is suddenly off or abnormal, inverter will change to off grid status
automatically. Energy from PV system and battery will supply the local load.
There are 4 types of timed charge and discharge control, each of which can be
set for 3 time periods respectively. It operates according to these four types
within the set time period, and resumes operation in the setting mode of
3.2.1~3.2.4 after the time expires.
3.2.6.1 AC Charge
During the set time period, the battery is charged with the set power. When the
PV power is not enough, the power is drawn from the grid until the set SOC is
reached, and the timing charging function is stopped.
3.2.6.2 Force Charge
During the set time period, the battery is charged with the set power, and the
power is only drawn from the PV, not from the grid, and the timing charging
function is stopped after the set SOC.
3.2.6.3 Force Discharge
During the set time period, discharge the battery with the set power until the set
SOC stops the timed discharge function.
3.2.6.4 Forbid discharge
During the set time period, the PV power will give priority to the charging, not
the load1.

Before connecting, a separate AC breaker between individual inverter and AC
input power is necessary. This will ensure the inverter be securely disconnected
during maintenance and fully protected from current of AC input.
An extra AC breaker is needed for On-Grid connection to be isolated from grid
when necessary. Below are requirements for the On-Grid AC-breaker.
•
Connect DC protector or breaker first before connecting.
• emove insulation sleeve 11mm(0.5 inch) length, unscrew the bolts, insert the
AC input wires according to polarities indicated on the terminal block and
tighten the terminal screws.
Note:
Qualified electrician will be required for the wiring.
The AC terminal contains “GRID” and “EPS”, GRID for load, and EPS for
emergency load.
