Installaon Precauon
This Hybrid inverter is designed for outdoor use(IP65), Please make sure the installaon site
meets below condions:
Please AVOID direct sunlight, rain exposure, snow laying up during installaon and
operaon. Before connecng all wires, please take off the metal cover by removing
screws as shown below:
· Not in direct sunlight
· Not in areas where highly flammable materials are stored.
· Not in potenal explosive areas.
· Not in the cool air directly.
· Not near the television Antenna or antenna cable.
· Not higher than altude of about 2000 meters above sea level.
· Not in environment of precipitaon or humidity(>95%)
Considering the following points before selecng where to install:
· Please select a vercal wall with load-bearing capacity for installaon, suitable for installaon
on concrete or other non-flammable surfaces,installaon is shown below.
· Install this inverter at eye level in order to allow the LCD display to be read at all mes.
· The ambient temperature should be between -25~60℃ to ensure opmal operaon.
· Be sure to keep other objects and surfaces as shown in the diagram to guarantee sufficient
heat dissipaon and have enough space for removing wires.

For proper air circulaon 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.
Mounng 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,
52-60mm 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.
3. Fasten the screw head of the expansion bolt to finish the mounng.

For safe operaon and compliance, a separate DC over-current protector or disconnect device is
required between the baery and the inverter. In some applicaons, switching devices may not
be required but over-current protectors are sll required. Refer to the typical amperage in the

Please follow below steps to implement baery connecon:
1. Please choose a suitable baery cable with correct connector which can well fit into the
baery terminals.
2. Use a suitable screwdriver to unscrew the bolts and fit the baery connectors in, then
fasten the bolt by the screwdriver, make sure the bolts are ghtened with torque of
24.5 N.M in clockwise direcon.
3. Make sure polarity at both the baery and inverter is correctly connected.
Connecng the baery with a suitable cable is important for safe and efficient
operaon 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.
3. In case of children touch or insects go into the inverter, Please make sure the inverter
connector is fasten to waterproof posion by twist it clockwise.
Before making the final DC connecon or closing DC breaker/disconnect, be sure
posive(+) must be connect to posive(+) and negave(-) must be connected to
negave(-). Reverse polarity connecon on baery will damage the inverter.
Installaon must be performed with care.

3.4 Grid connecon and backup load connecon
1. Before making Grid, load and Gen port connecon, be sure to turn off AC baeaker or
disconnector first.
2. Remove insulaon sleeve 10mm length, unscrew the bolts, insert the wires according to
polaries indicated on the terminal block and ghten the terminal screws. Make sure the
connecon is complete.
Please follow below steps to implement Grid, load and Gen port connecon:
Chart 3-3 Recommended Size for AC wires
· Before connecng 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 for the load port is 20A for 8kw, 32A for 10kw and
32A for 12KW. The recommended of AC breaker for the grid port is 63A for 8kw, 63A for 10kw
and 63A for 12KW.
All wiring must be performed by a qualified personnel.It is very important for
system safety and efficient operaon to use appropriate cable for AC input
connecon. To reduce risk of injury, please use the proper recommended cable
as below.

3. Then, insert AC output wires according to polaries indicated on the terminal block and ghten
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 condioner are required at least 2-3 minutes to restart because it is
required to have enough me to balance refrigerant gas inside of circuit. If a power shortage
occurs and recovers in short me, it will cause damage to your connected appliances. To
prevent this kind of damage, please check manufacturer of air condioner if it is equipped with
me-delay funcon before installaon. Otherwise, this inverter will trigger overload fault and
cut off output to protect your appliance but somemes it sll causes internal damage to the air
condioner
Before connecng to PV modules, please install a separately DC circuit breaker between
inverter and PV modules. It is very important for system safety and efficient operaon to
use appropriate cable for PV module connecon. 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 aempng to wire it to the
unit.
To avoid any malfuncon, 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 be sure NO grounding.
It is requested to use PV juncon box with surge protecon. Otherwise, it will
cause damage on inverter when lightning occurs on PV modules.

2. Switch the DC lsolator OFF.
3. Assemble PV input connector to the inverter.
Safety Hint:
Please don’t connect PV array posive or negave pole to the ground, it could
cause serious damages to the inverter.
Safety Hint:
Before connecng inverter, please make sure the PV array open circuit voltage is
within the 1000V of the inverter.
GFDI fault:
Before the inverter starts to connect to the grid, the inverter will first
detect the impedance of PV + to ground, and the impedance of PV-
to ground. If any of these impedance values is less than 33 kΩ, the
inverter will not connect to the grid and will report an error
F04 on its LCD.At the same me, the buzzer will sound.
Safety Hint:
Before connecon, please make sure the polarity of the output voltage of PV
array matches the “DC+” and “DC-” symbols.

The steps to assemble the DC connectors are listed as follows:
a) Strip off the DC wire about 7mm, disassemble the connector cap nut (see picture 5.3).
b) Crimping metal terminals with crimping pliers as shown in picture 5.4.
c) Insert the contact pin to the top part of the connector and screw up the cap nut to the top
part of the connector. (as shown in picture 5.5).

Warning:
Sunlight shines on the panel will generate voltage, high voltage in series may
cause danger to life. Therefore, before connecng the DC input line, the solar
panel needs to be blocked by the opaque material and the DC switch should
be 'OFF', otherwise, the high voltage of the inverter may lead to life-
threatening condions.
