1.About This Manual
1.1 Scope of Validity
This manual mainly describes the product information, guidelines for installation, operation,
maintenance and troubleshooting. And this manual applies to Afore AF-DH series hybrid
inverters.
Please keep this manual stored carefully and accessible at any time.
Contents may be updated due to product development, the latest version can be acquired via
www.aforenergy.com.
1.2 Target Group
This manual and the tasks described are for qualified electricians.
2.Safety Guidance
2.1 Safety Instruction
All the work on AF-DH series should be carried out by qualified electricians. Children will not
access to the inverter.
The PV (Photovolatic) modules and the hybrid inverters should be connected to the ground
separately in order to protect property and persons.
Do not touch cover until five minutes after disconnecting PV panels, battery, the grid, and
generator to avoid electric shock.
To reduce the risk of injury, do not touch the hot cover, heat sink at the back of the hybrid
inverter or surfaces nearby while inverter is operating.
Do not use the inverter for other purposes that not described in this manual.
Both the inverter and associated transport packaging are mainly made of recyclable raw
materials. Please ensure that the used device and relevant accessories have been disposed
of in accordance with applicable regulations.
Packed with EPE foam and carton, the inverter should be placed upwards and handled
carefully during delivery. Pay attention to waterproof.
Alternative applications, modifications to the inverter are not recommended. Installation of
components that is not authorized by Afore New Energy will make the warranty claims
invalid.

2.2 Symbols
AF-DH series hybrid inverters strictly comply with relevant safety standards. Please read and
follow all the instructions and cautions before installation, operation and maintenance.
3.Introduction
3.1 Basic Instruction
AF-DH series hybrid inverters, when work with batteries can significantly reduce the energy that
purchased from the public grid and optimize self-consumption.

５
1. Solar energy system can work without PV or Battery.
2. Off-grid application is available.
3. With anti-feed-in (default value 0).
3.2 Operation Modes
3.2.1 Self- use
A. Normal Mode
Priority: Load > Battery > Grid
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.
B.Stabilize the Power of the Grid
In special self-use mode, the power needs to be fed in/exported from the grid stably with a
target value(default value 0), thus keeping grid-friendly in some areas.

６
3.2.2 Timing Charging
This mode applies to situation with peak-valley electricity price. Battery can be charged during
off-peak hours.
The charging and discharging time can be set flexibly, it also allows to set whether charge from
the grid or not.
3.2.3 Selling First
Priority: Load > Grid > Battery
This mode applies to situation with high feed in subsidy.
1. Solar energy supply the local load first, then export to the public grid.
2. The excess energy will be charged into the battery.

７
3.2.4 Backup 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.
3.2.5 Emergency Charging
When the voltage or SOC (state of charge) of the battery is below the safe value, battery will be
charged in priority until to the safe value.
The energy of the battery will be taken from the public grid and PV system. When the public grid
is off, the battery can only be supplied by PV system.

８
3.2.6 EPS
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.
4.Installation
4.1 Pre-installation
Check the equipment before installation to make sure whether the packaging and components
are lost or damaged, if it is, please contact local distributor directly for support.

4.1.3 Mounting Location
AF-DH series hybrid inverters are designed for indoor and outdoor installation (IP65), make sure
the mounting location meets the following conditions :
Inverters should be installed on a solid surface
Inverters should be away from flammable materials, the television antenna or antenna
cable
The mounting structure can support the weight of the inverter.
The ambient temperature should be within -25℃~ 60℃.
Please AVOID direct sunlight, rain exposure, snow laying up and lightning
