3.4.3 Generator mode
I. Generator access function (dry contact control)
In the off grid mode, when the battery is discharged to the under voltage alarm point, HPS sends a relay
signal to start the DG and enter DG mode. The generator will supply power to load; at the same time,
HPS stops supplying power to the load and only charges the battery.
1. When PV power is greater than the charging power, PV power is only used to charge the battery; the
DG only supplies the load.
2. When PV power is less than the charging power, PV supplies priority to battery; DG supplies power to
the load and optionally charges the battery.
3. When the battery is charged to "SOC upper limit" or "floating charge current limiting point"
(depending on the battery type), the inverter sends a signal to stop the DG and switch to off grid mode.
4. When there is no power grid, the DG can be directly connected to the power grid end of the inverter;
when there is power grid and DG neither, it needs to be used with ATS.
See Chapter 7.2.4 for details of setting SOC upper limit and floating charge current limiting point.
3.4.4 PV mode
1. When utility is unavailable, turn on the knob without clicking the LCD power-on key, HPS will start to
enter PV mode, then PV only charges the battery and will not invert AC output.
2. When utility is unavailable, manually start the LCD screen in PV mode, then inverter enters off grid
mode.
3. In the off grid mode when discharged to the battery low voltage alarm point, inverter will stop DC/AC
converting and automatically switch to PV mode. When battery is charged to the set voltage(single PV to
off-grid), it automatically switches to off grid mode.
4. When the power grid returns normal, inverter automatically switch to grid tie mode.
See Chapter 7.2.4 for details on charge change to offline.
3.4.5 Automatic on/off grid switch
Operate logic: when the power grid is normal, cut the grid automatically, otherwise when the power grid
is abnormal, cut off the grid automatically.
3.4.6 Fault mode
When the inverter fails, the contactor on AC and DC sides will immediately disconnect andshut down the
inverter, so as to ensure the system safety. At this time, the inverter will continuously monitor whether the
fault is eliminated, If not, it will maintain the fault state; after eliminated, it will restart automatically.
3.4.7 Permanent failure mode
When the invertrer has a serious fault, the contactor on AC and DC sides will immediately disconnect and
enter a permanent fault state to ensure safety of the system. When permanent fault is detected three
times in a row, all switches will be disconnected. For example, the IGBT module of the inverter is faulty.
When inverter enters this permanent failure mode, please do not repair it without permission. You should
contact the personnel of the local dealer or call Shenzhen Atess Power Technology Co., Ltd. for help.
When temperature gets too high, output power of the inverter will decrease,
which is normal. However, if this happens frequently, check the cooling surface of
the inverter or place it in a place with good ventilation condition. If the fan gets
dirty, please clean the dust on it. If there is any problem inside the inverter, please
contact the professional service department for help.

When paralleling two HPS models, DB9 communication line is used to connect the parallel interfaces
of two models. One of the two parallel interfaces on the control board can be selected as the reserved
interface.
when two HPS are used in parallel.
As Parallel function is a special customized function, users cannot parallel the models on their
own. The parallel equipment shall not be changed to stand-alone without authorization.
ATESS is not responsible for the consequences caused by not operating as required.
When the system needs to be connected to utility grid and gemerator at the same time, an ATS is
required to be used together with HPS, which is mainly used to switch between the utility and generator.
2. The main wiring of ATS and HPS is ATS internal panel power line, CAN communication line and AC
power line.
Wiring diagram is shown as below:
5.6 ATS wiring

Wiring instructions:
1. PV modules can be separated or shared. When separating, PV configuration of the two units should be
same as much as possible.
2. In order to reduce the circulation loss, it is recommended to share the battery. When it is a lithium
battery with BMS, both computers need to communicate with BMS.
3. The two HPS supply load together, The load terminals of the two paralleled units are connected before
connecting to load, and the length from combination point of the two HPS to the load terminals must be
the same.
4. The two HPS share the utility grid or generator. When require to switch between these two power
source, it shall be used with ATS. The installation method is the same as that of single unit installation.
5. The parallel system has a special parallel communication line, which directly connects the parallel ports
of the two machines, and the line is provided by ATESS; Pay attention to interference, and avoid strong
electricity when routing.
6. In order to ensure the communication quality, please install the two computers at the same location to
reduce the communication transmission distance, and the complimentary line of parallel communication is
only 5 meters long.
Operation mode:
The paralleled HPS operation mode is the same as when it works in single unit.
The system can select parallel backup function.
No backup:
1. When off-grid, the paralleled inverter must be started and shut down at the same time. When starting
up, two units shall be started together, Start unit 1, it can only enter the parallel to off-grid mode (no AC
output), and then can enter the off-grid mode together after unit 2 is started; after unit 1 enters the fault
state, unit 2 shall enter the parallel to off-grid mode (no AC output), and then enter the off-grid mode
together after unit 1 is started.
2. When the inverter in off-grid operation needs to switch into on-grid mode, all inverters need to be
ready, and then enter on-grid mode at the same time. It is not allowed that one machine running in on-
grid mode, and the other in off grid mode.
Backup:
1. When off-grid, the paralleled inverter does not need to be started and closed at the same time. It can
operate in the single off network mode, and disconnect and access from the parallel at any time.
2. When the energy storage controller in off grid operation needs to be connected to the grid, it does not
need all the energy storage controllers to be ready to enter into the grid connection mode, but only needs
to meet the grid connection conditions to be connected to the grid.
3. One machine is not allowed to operate in grid connected mode and one machine operates in off grid
mode.
Description of backup enable selection:
When the load power exceeds the maximum load power of the single energy storage controller, it is not
recommended to use the backup function, otherwise the overload of the energy storage controller will
often lead to shutdown, and the load will be completely powered off.
