Please follow below steps to implement baery connecon:
1. Please choose a suitable baery cable with correct connector which can well fit into the
baery terminals.
2. Use a suitable screwdriver to unscrew the bolts and fit the baery connectors in, then
fasten the bolt by the screwdriver, make sure the bolts are ghtened with torque of
24.5 N.M in clockwise direcon.
3. Make sure polarity at both the baery and inverter is correctly connected.
Connecng the baery with a suitable cable is important for safe and efficient
operaon 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 posion by twist it clockwise.
Before making the final DC connecon or closing DC breaker/disconnect, be sure
posive(+) must be connect to posive(+) and negave(-) must be connected to
negave(-). Reverse polarity connecon on baery will damage the inverter.
Installaon must be performed with care.

3.4 Grid connecon and backup load connecon
1. Before making Grid, load and Gen port connecon, be sure to turn off AC baeaker or
disconnector first.
2. Remove insulaon sleeve 10mm length, unscrew the bolts, insert the wires according to
polaries indicated on the terminal block and ghten the terminal screws. Make sure the
connecon is complete.
Please follow below steps to implement Grid, load and Gen port connecon:
Chart 3-3 Recommended Size for AC wires
· Before connecng 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 operaon to use appropriate cable for AC input
connecon. To reduce risk of injury, please use the proper recommended cable
as below.

3. Then, insert AC output wires according to polaries 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 condioner 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 condioner if it is equipped with
me-delay funcon before installaon. Otherwise, this inverter will trigger overload fault and
cut off output to protect your appliance but somemes it sll causes internal damage to the air
condioner
Before connecng to PV modules, please install a separately DC circuit breaker between
inverter and PV modules. It is very important for system safety and efficient operaon to
use appropriate cable for PV module connecon. 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 aempng to wire it to the
unit.
To avoid any malfuncon, 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 juncon box with surge protecon. 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 posive or negave pole to the ground, it could
cause serious damages to the inverter.
Safety Hint:
Before connecng 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 connecon, 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 connecng 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 condions.
