Installation Precaution
This Hybrid inverter is designed for outdoor use(IP65), Please make sure the installation site
meets below conditions:
Please AVOID direct sunlight, rain exposure, snow laying up during installation and
operation. Before connecting all wires, please take o the metal cover by removing
screws as shown below:
· 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%)
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-flammable 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 recommeded to be between -40~60℃ to ensure optimal operation.
· Be sure to keep other objects and surfaces as shown in the diagram to guarantee sucient
heat dissipation and have enough space for removing wires.

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.
Mounting the inverter
Remember that this inverter is heavy! Please be careful when liing out from the package.
Choose the recommend drill head(as shown in below pic) to drill 4 holes on the wall,
82-90mm deep.
1. Use a proper hammer to fit the expansion bolt into the holes.
2. Carry the inverter and holding it, make sure the hanger aim at the expansion bolt,fix the
inverter on the wall.

For safe operation and compliance, a separate DC over-current protector or disconnect device is
required between the battery and the 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.

For 7.6KW/8KW model, battery connector screw size: M10
Please follow below steps to implement battery connection:
1. Please choose a suitable battery cable with correct connector which can well fit into the
battery terminals.
2. Use a suitable screwdriver to unscrew the bolts and fit the battery
connectors 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 inverter is correctly connected.
Connecting the battery with a suitable cable is important for safe and ecient
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 person.
4. In case of children touch or insects go into the inverter, Please make sure the inverter
connector is fasten to waterproof position by twist it clockwise.
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 inverter.
Installation must be performed with care.

3.4 Grid connection and backup load connection
Please follow below steps to implement AC input/output connection:
Chart 3-3 Recommended Size for AC wires
· Before connecting to grid, please install a separate AC breaker between inverter and grid. Also,
it is recommended that installs an AC breaker between backup load and inverter.This will ensure
the inverter can be securely disconnected during maintenance and fully protected from over
current. The recommended of AC breaker is 40A for 5kw and 63A for 8KW.
· 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 ecient operation to use appropriate cable for AC input
connection. To reduce risk of injury, please use the proper recommended cable
as below.

1. Before making Grid, load and Gen port connection, be sure to turn o AC breaker or
disconnector first.
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 complete.

3. Then, insert AC output wires according to polarities indicated on the terminal block and tighten
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 manufacturer of air conditioner if it is equipped with
time-delay function before installation. Otherwise, this inverter will trigger overload fault and
cut o output to protect your appliance but sometimes it still causes internal damage to the air
conditioner
Before connecting to PV modules, please install a separately DC circuit breaker between
inverter and PV modules. It is very important for system safety and ecient operation to
use appropriate cable for PV module connection. To reduce risk of injury, please use the
proper recommended cable size as below.
Chart 3-4 Cable size
Be sure that AC power source is disconnected before attempting to wire it to the
unit.
To avoid any malfunction, do not connect any PV modules with possible current
leakage to the inverter. For example, grounded PV modules will cause current
leakage to the inverter. When using PV modules, please ensure the PV+ & PV- o
f solar panel is not connected to the system ground bar.
It is requested to use PV junction box with surge protection. Otherwise, it will
cause damage on inverter when lightning occurs on PV modules.

3.5.1 PV Module Selection:
3.5.2 PV Module Wire Connection:
When selecting proper PV modules, please be sure to consider below parameters:
1) Open circuit Voltage (Voc) of PV modules not exceeds max. PV array open circuit voltage of
inverter.
2) Open circuit Voltage (Voc) of PV modules should be higher than min. start voltage.
3) The PV modules used to connected to this inverter shall be Class A rating certified according
to lEC 61730.
Please follow below steps to implement PV module connection:
1. Remove insulation sleeve 10 mm for positive and negative conductors.
2. Suggest to put bootlace ferrules on the end of positive and negative wires with a proper
crimping tool.
3. Check correct polarity of wire connection from PV modules and PV input connectors. Then,
connect positive pole (+) of connection wire to positive pole (+) of PV input connector. Connect
negative pole (-) of connection wire to negative pole(-)of PV input connector. Close the switch
and make sure the wires are tightly fixed.
