Selecting the Mounting Area
Considering the following points before selecting where to install:
Please select a vertical wall with load-bearing capacity for installation, suitable for installation on concrete
or other non-ammable surfaces, installation is shown below.
Install this inverter at eye level in order to allow the LCD display to be read at all times.
The ambient temperature is recommended to be between -40~60ºC to ensure optimal operation.
Be sure to keep other objects and surfaces as shown in the diagram to guarantee sucient heat dissipa-
tion and enough space to remove wires.
This Hybrid Inverter is designed for outdoor use (IP65), DO NOT install the inverter in the following
areas:
Areas with high salt content, such as the marine environment. It will deteriorate the metal parts and
possibly lead to water/dampness penetrating the unit.
Areas lled with mineral oil or containing splashed oil or steam, such as those found in kitchens. It will
deteriorate plastic parts of the unit, causing those parts to fail or allowing water/damp to penetrate the
unit.
Areas that generate substances that adversely aect the equipment, such as sulphuric gas, chlorine gas,
acid, or alkali. These can cause the copper pipes and brazed joints to corrode and fail to conduct
electricity reliably.
Areas that can cause combustible gas to leak, which contains suspended carbon-bre or ammable
dust, or volatile inammable such as paint thinner or gasoline.
Areas where there may be gas leaks and where gas may settle around the unit as this is a re risk.
Areas where animals may urinate on the unit or ammonia may be generated.
High altitude areas (over 2000 metres above sea level).
Environments where precipitation or humidity is above 95%
Areas where the air circulation is too low.
Please AVOID direct sunlight, rain exposure, snow laying up during installation and operation. Before con-
necting all wires, please take o the metal cover by removing screws as shown below:

Choose the recommended drill head (as shown below pic) to drill 4 holes in the wall, 82-90mm deep.
1. Use a proper hammer to t the expansion bolt into the holes.
2. Carry and hold the inverter, ensure the hanger aims at the expansion bolt, and x the inverter on the
wall.
3. Fasten the screw head of the expansion bolt to nish the mounting.
WARNING
Risk of injury (Heavy Object).
Remember that this inverter is heavy so users must be careful in handling the unit during installation
especially when mounting or removing from a wall.
Mounting the Inverter
WARNING
For proper air circulation to dissipate heat, allow a clearance of approx. 50cm to the side and approx.
50cm above and below the unit. And 100cm to the front.
Install the indoor unit on the wall where the oor height is higher than 1600mm.
For proper heat dissipation, allow a clearance of approximately 500mm to the side, 500mm above and
below the unit, and 1000mm to the front of the unit.

SINGLE PHASE HI 10/12kW | User Manual15
Battery Connection
For safe operation and compliance, a separate DC over-current protector or disconnect device is required
between the battery and the inverter. Switching devices may not be required in some applications, but
over-current protectors are still required. Refer to the typical amperage in the table below for the required
fuse or circuit breaker size.

WARNING
All wiring/connecting must be performed by qualied personnel. Before making the nal DC
connection or closing the DC Breaker/disconnection device, ensure the inverter unit is wired
correctly. A reverse-polarity connection on the battery will damage the inverter.

SINGLE PHASE HI 10/12kW | User Manual16
Please follow the below steps to implement battery connection:
Please choose a suitable battery cable with the correct connector which can well t into the battery
terminals.
Use a suitable screwdriver to unscrew the bolts and t the battery connectors in, then fasten the bolt
with the screwdriver, ensuring the bolts are lightened with a torque of 24.5 N.m in a clockwise direction.
Make sure the polarity at both the battery and inverter is correctly connected.
In case of children touching or insects entering the inverter. Please make sure the inverter connector is
fastened to a waterproof position by twisting it clockwise.
WARNING
Reverse Polarity.
Before making the nal DC connection or closing DC breaker/disconnect, be sure positive (+) must
be connected to the positive (+) and negative (-) must be connected to the negative (-). A reverse
polarity connection on the battery will damage the inverter.

Connecting the AC
Before connecting to the grid, a separate AC breaker must be installed between the inverter and the grid,
and also between the backup load and the inverter. This will ensure the inverter can be securely disconnect-
ed during maintenance and fully protected from over current. For the 10/12kW model, the recommended
AC breaker for backup load is 100A. For the 10/12kW model, the recommended AC breaker for grid is 100A.
There are three terminal blocks with “Grid” “Load” and “GEN” markings. Please do not misconnect the input
and output connectors.
GEN/AUX Generator connection.
GRID This works like a conventional grid-tied inverter. It is both an input and output
connection for non-essential load and supply.
LOAD Connection of essential loads such as lighting, security systems, and internet.
Model Wire Size Cable (mm2 ) Torque Value (Max.)
10kW / 12kW 4AWG 21.1 1.2N.m
WARNING
All wiring must be performed by qualied personnel. System safety and ecient operation need to
use appropriate cable for AC input connection. To reduce the risk of injury, please use the recom-
mended cable below.
Please follow the steps below to implement GRID, LOAD, and GEN port connections:
1. Before making Grid, Load, and Gen port connections, make sure to turn o the AC breaker or
disconnector rst.
2. Remove a 10mm sleeve from each wire, unscrew the bolts, insert the wires according to the polarities
indicated on the terminal block and tighten the terminal screws. Ensure the connection is complete.
3. Then, insert AC output wires according to the polarities indicated on the terminal block and tighten the
terminal. Make sure to connect corresponding N wires and PE wires to related terminals as well.
4. Ensure the wires are securely connected.
5. Appliances such as air conditioners are required at least 2-3 minutes to restart because it requires
enough time to balance refrigerant gas inside the circuit. If a power shortage occurs and recovers in a
short time, it will cause damage to your connected appliances. To prevent this kind of damage, please
check with the air conditioner manufacturer if it is equipped with a time-delay function before installa-
tion. Otherwise, this inverter will trigger an overload fault and cut o output to protect your appliance,
but sometimes it still causes internal damage to the air conditioner
