3.2 Mounting instructions
Installation Precaution
This Smart Hybrid inverter is designed for outdoor use(IP65), Please make sure the
installation site meets below conditions:
Not in direct sunlight
Not in areas where highly flammable materials are stored.
Not in potential explosive areas.
Not in the cool air directly.
Not near the television Antenna or antenna cable.
Not higher than altitude of about 2000 meters above sea level.
Not in environment of precipitation or humidity (>95%)
Please AVOID direct sunlight, rain exposure, snow laying up during installation and
operation. Before connecting all wires, please take off the metal cover by removing
screws as shown below:
Consider 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-flammable surfaces, installation is shown below.
Install this smart inverter at eye level in order to allow the LCD display to be read at
all times.
The ambient temperature should be between -25~60℃to ensure optimal
operation. Be sure to keep other objects and surfaces as shown in the diagram to
guarantee sufficient heat dissipation and have enough space for removing wires.

≥500mm
For proper air circulation to dissipate heat, allow a clearance of approximate 50cm to the
side and approximate 50cm above and below the unit. And 100cm to the front.
Mounting the smart inverter
Remember that this smart inverter is heavy! Please be careful when lifting out from the
package. Choose the recommend drill head (as shown in below pic) to drill 4 holes on the
wall, 52-60mm deep.
1. Use a proper hammer to fit the expansion bolt into the holes.
2. Lift the smart inverter and hold it, make sure the hanger aims at the expansion bolt, then
fix the smart inverter on the wall.
3. Fasten the screw head of the expansion bolt to finish the mounting.

3.3 Battery connection
For safe operation and compliance, a separate DC over-current protector or disconnect
device is required between the battery and the smart inverter. In some applications,
switching devices may not be required but over-current protectors are still required. Refer
to the typical amperage in the table below for the required fuse or circuit breaker size.

Please follow the steps below to connect the battery:
1. Please choose a suitable battery cable and the correct cable lug that can fit the battery
terminals.
2. Use a suitable screwdriver to unscrew the bolts and fit the battery cable lug in, then
fasten the bolt by the screwdriver, make sure the bolts are tightened with torque of 24.5
N.m in clockwise direction.
3. Make sure polarity at both the battery and smart inverter is correctly connected.
For 8kW model, battery connector screw size: M10
4. To prevent children touching or insects going into the smart inverter, please make sure
the smart inverter connector is fastened to waterproof position by twisting it clockwise.
Installation must be carried out with care.
Before making the final DC connection or closing DC breaker/disconnect, be
sure positive (+) must be connect to positive (+) and negative (-) must be
connected to negative (-). Reverse polarity connection on battery will damage
the smart inverter.
Connecting the battery with a suitable cable is important for safe and efficient
operation of the system. To reduce the risk of injury, refer to Chart 3-2 for
recommended cables.
All wiring must be performed by a professional.

3.4 Grid connection and backup load connection
Before connecting to grid, please install a separate AC breaker between smart inverter and
grid. Also, it is recommended that you install an AC breaker between backup load and smart
inverter. This will ensure that the smart inverter can be securely disconnected during
maintenance and fully protected from over current. For the 8kW model, the recommended
AC breaker for backup load is 20A.
There are three terminal blocks with "Grid" "Load" and "GEN" markings. Please do not
misconnect input and output connectors.
All wiring must be performed by a qualified personnel. It is very important
for system safety and efficient operation to use appropriate cable for AC input
connection. To reduce risk of injury, please use the proper recommended
cable as below.

Please follow below steps to implement AC input/output connection:
1. Before making Grid, load and Gen port connection, be sure to turn off or disconnect AC
breaker.
2. Remove insulation sleeve 10mm length, unscrew the bolts, insert the wires according to
polarities indicated on the terminal block and tighten the terminal screws. Make sure the
connection is tight.

3. Then, insert AC output wires according to polarities indicated on the terminal block and
tighten the terminal. Be sure to connect corresponding N wires and PE wires to related
terminals as well.
4. Make sure the wires are securely connected.
5. Appliances such as air conditioner are required at least 2-3 minutes to restart because it is
required to have enough time to balance refrigerant gas inside of circuit. If a power
shortage occurs and recovers in short time, it will cause damage to your connected
appliances. To prevent this kind of damage, please check with the manufacturer of the air
conditioner, if it is equipped with time-delay function before installation. Otherwise, this
smart inverter will trigger overload fault and cut off output to protect your appliance but
sometimes it still causes internal damage to the air conditioner
3.5 PV Connection
Before connecting to PV modules, please install a separately DC circuit breaker between
smart inverter and PV modules. It is very important for system safety and efficient
operation to use appropriate cable for PV module connection. To reduce risk of injury,
please use the proper recommended cable size as below.

To avoid any malfunction, do not connect any PV modules with possible current
leakage to the smart inverter. For example, grounded PV modules will cause
current leakage to the smart inverter. When using PV modules, please be sure
PV+ and PV- are not grounded
It is requested to use PV junction box with surge protection. Otherwise, it will
cause damage on smart inverter when lightning occurs on PV modules.
