electrical equipment, the relevant safety instructions must be observed before any operation on the
equipment. Improper operation may lead to serious injury or property damage.
!
Due to product version upgrading or other reasons, the document content will be updated from
time to time. If there is no special agreement, the document content cannot replace the safety
precautions in the product label. All descriptions in this document are for guidance only.
Please read this document carefully for products and precautions before installing the equipment.
Professional and qualified electrical technicians who shall be familiar with the relevant standards
and safety specifications of the project site must carry out all equipment operations.
Insulation tools and personal protective equipment shall be used to ensure personal safety during
inverter operation. Electrostatic gloves, wrist strap and antistatic clothing shall be worn when
contacting with electronic devices to protect the inverter from electrostatic damage.
Equipment damage or personal injury caused by inverter not installed, used or configured in
accordance with the requirements of this document or corresponding user manual is not within
the responsibility scope of equipment manufacturer.
Please use the DC wiring terminals provided with the box to connect the inverter DC cable. If other
types of DC wiring terminals are used, serious consequences may be caused, and the equipment
damage caused thereby is not within the scope of the equipment manufacturer.
The solar array (solar panel) will have DC high voltage.
PV panel used with inverters must have IEC 61730 class A rating or other equivalent standard
class.
Make sure good grounding of component frame and support system.
Do not ground the PV array positive (+) or negative (-) as this may cause serious damage to the
inverter.
Make sure that the DC cables are firmly connected without looseness after connection.
Use a multimeter to measure the positive and negative electrodes of the DC cable. Make sure
that the positive and negative electrodes are correct, no reverse connection occurs and the
voltage is within the allowable range.
Do not connect the same PV string to multiple inverters, or the inverter may be damaged.
In order to reduce the risk of fire, the inverter connected circuit requires an overcurrent protection
device (OCPD). DC OCPD shall be installed according to local requirements. All PV power
supplies and circuit conductors shall have disconnect connections in accordance with NEC
Article 690, Part II.

PV string output does not support grounding. Before connecting PV string to inverter, please make
sure that the minimum insulation resistance to ground of PV string meets the minimum insulation
impedance requirements (R=maximum input voltage/30mA).
Make sure that the DC cables are firmly connected without looseness after connection.
Use a multimeter to measure the positive and negative electrodes of the DC cable and ensure that
the positive and negative electrodes are correct without reverse connection, and the voltage is
within the allowable range.
Do not connect the same PV string to multiple inverters, otherwise the inverter may be damaged.
Please make sure that the maximum short circuit current and maximum input voltage of each
MPPT are within the allowable range of the inverter.
Please make sure that the positive electrode of the PV string is connected to the PV port+of the
inverter, and the negative electrode of the PV string is connected to the PV port - of the inverter.
Please prepare your own PV input cable. Recommended specification:

In order to ensure that the inverter and the grid can be safely disconnected from the grid in case of
abnormal conditions, please connect the AC switch on the AC side of the inverter. Multiple
inverters cannot be connected to one AC switch at the same time. Please select proper AC switch
according to local regulations.
Please prepare the AC output cable. See the figure for the recommended specification:
If multi-core copper wire is selected, supporting crimping terminal shall be used for assembly. It is
forbidden to directly press multi-core copper wire into the connector.
5.3.4 Connecting AC cable
Residual current monitoring unit (RCMU) is integrated in the inverter. When the inverter detects
leakage current greater than the allowable value, it will quickly disconnect from the grid.
During wiring, the AC cable is completely matched with "L1", "L2", "L3", "N" and grounding port of
AC terminal. If the cable is connected improperly, the equipment will be damaged.
Make sure that the core is completely inserted into the terminal hole without exposure.
Ensure that the cables are firmly connected, otherwise the terminal may be overheated and the
equipment may be damaged when the equipment is operating.

ASN three-phase inverter can meet the requirements of zero power export through one intelligent
meter and three CTs. It can be set as separate phase control and three-phase sum control as required.
Taking 12kW model as an example:
Single-phase independent control: three-phase on grid power is independently adjusted. For example,
if the load of L1/L2/L3 phase is 1kW/4kW/8kW respectively, then the output power of L1/L2/L3 will be
1kW/1kW/1kW respectively (the maximum single-phase on grid power of 12kW model is 4kW). The
remaining power required will be purchased from the grid.
Total power control: sum regulation of three-phase grid-connected power. If L1/L2/L3 phase load is
1kW/4kW/8kW respectively, then L1/L2/L3 output power will be 4kW/4kW/4kW respectively (12kW
model single-phase maximum grid connection power is 4kW). The remaining power required will be
purchased from the grid.

At the AC switch between the inverter and the power grid, measure the voltage at the power
grid side with a multi-meter, and confirm that the power grid voltage is at the working power of
the inverter Allowable pressure range.
Close the AC switch between inverter and utility/national grid.
Set "DC SWITCH" on the inverter to "ON".
Observe the inverter LED indicator and check the inverter operation status.

Watch out:
To ensure that the inverter works properly, please use the AUXSOL application program to complete
the inverter parameter setting.
!
Watch out:
Please also obtain the operating instructions of the communication rod from the official website, to
set the contents more consistent with the application scenario.
6.4 Power off the equipment
When operating and maintaining the inverter, please turn off the inverter for treatment. Live
operation of the equipment may cause damage to the inverter or electric shock.
After the inverter is powered off, it will take a certain amount of time for internal components to
discharge. Please wait until the equipment is fully discharged according to the required label time
requirements.
Disconnect the AC switch between the inverter and the utility/ national grid.
At the AC switch between the inverter and the utility/ national grid, measure the voltage on the
power grid side with a multi-meter to confirm that the power has been cut off.
Observe the inverter LED indicator, and confirm to enter standby.
Set "DC SWITCH" on inverter to "OFF".

cable, communication module and protective earth wire.
Remove the inverter from the back cladding.
Remove the back cladding.
Properly save the inverter and ensure that the storage conditions meet the requirements if the subsequent
inverter is still put into use.
If the inverter cannot be used anymore and needs to be scrapped, please dispose according to the electrical waste
disposal requirements of the inverter country/region.
The inverter shall not be treated as household garbage.
Please troubleshoot according to the following methods. If the troubleshooting methods cannot help you, please
contact the after-sales service center.
When contacting the after-sales service center, please collect the following information for quick solution.

blocking the fan and affecting the operation of the inverter.
Check whether the tightness of the equipment inlet hole meets the
requirements. If the gap is too large or not sealed, it shall be re-closed.
Turn on and off the DC switch for 10 times continuously to ensure the
normal function of DC switch.
Check whether the electrical connection is loose, whether the cable
appearance is damaged and whether there is copper leakage.
