⚫Please follow below steps to implement battery connection
1. Remove insulation sleeve 18 mm for positive and negative cables based on recommended
stripping length.
2. Connect all battery packs as units requires. It’s suggested to use recommended battery
capacity.
3. Insert battery cable flatly into battery connector of inverter and make sure the bolts are tightened
with torque of 2-3 Nm. Make sure polarity at both the battery and the inverter/charge is correctly
connected and the battery cables are tightly screwed to the battery connector.
CAUTION
⚫For safety operation and regulation compliance, it’s requested to install a separate DC over-
current protector or disconnect device between battery and inverter. It may not be requested
to have a disconnect device in some applications, however, it’s still requested to have
over-current protection installed. Please refer to typical amperage in below table as required
fuse or breaker size.
WARNING
⚫All wiring must be performed by a qualified personnel.
⚫It's very important for system safety and efficient operation to use
appropriate cable for battery connection. To reduce risk of injury,
please use the proper recommended cable, stripping length (L2)
and tinning length (L1) as shown on the right.

CAUTION
⚫Do not place anything between the flat part of the inverter terminal Otherwise, overheating
may occur.
⚫Do not apply anti-oxidant substance on the terminals before terminals are connected tightly.
⚫Before making the final DC connection or closing DC breaker/disconnector, be sure positive
(+) must be connected to positive (+) and negative (-) must be connected to negative (-).
WARNING
⚫Installation must be performed with care due to high battery voltage in series.

⚫Please follow below steps to implement AC input/output connection
1. Before making AC input/output connection, be sure to open DC protector or disconnector first.
2. Remove insulation sleeve 10mm for six conductors. And shorten phase L and neutral
conductor N 3mm.
3. Insert AC input wires according to polarities indicated on terminal block and tighten the terminal
screws. Be sure to connect PE protective conductor ( ) first.
→Ground (yellow-green) L→LINE (brown or black) N→Neutral (blue)
CAUTION
⚫Before connecting to AC input power source, please install a separate AC breaker between
inverter and AC input power source. This will ensure the inverter can be securely
disconnected during maintenance and fully protected from over current of AC input. The
recommended spec of AC breaker is 50A.
⚫There are two terminal blocks with “IN” and “OUT” markings. Please do NOT mis-connect
input and output connectors.
WARNING
⚫All wiring must be performed by a qualified personnel.
⚫It’s 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 size
as below.

4. Then, insert AC output wires according to polarities indicated on terminal block and tighten
terminal screws. Be sure to connect PE protective conductor ( ) first.
→Ground (yellow-green) L→LINE (brown or black) N→Neutral (blue)
5. Make sure the wires are securely connected.
CT Connection
Inverter will not only provide power to the backup load connected but also give power to the home
load connected. If PV power is insufficient, it will take grid energy as supplement. The inverter will
not sell power to grid. In this mode, a CT is needed. The installation method of the CT please refer
to the chapter. The external CT will detect power flowing back to the grid and will reduce the power
of the inverter only to supply the local load, charge battery and home load.
WARNING
⚫Be sure that AC power source is disconnected before attempting to hardwire it to the unit.
CAUTION
⚫Be sure to connect AC wires with correct polarity. If L and N wires are connected reversely,
it may cause utility short-circuited when these inverters are worked in parallel operation.
⚫Appliances such as air conditioner are required at least 2~3 minutes to restart because it’s
required to have enough time to balance refrigerant gas inside of circuits. 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 manufacturer of air
conditioner if it’s equipped with time-delay function before installation. Otherwise, this
inverter/charger will trig overload fault and cut off output to protect your appliance but
sometimes it still causes internal damage to the air conditioner.

PV Module Selection
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. battery voltage.
CAUTION
Before connecting to PV modules, please install separately a DC circuit breaker between
inverter and PV modules.
WARNING
All wiring must be performed by a qualified personnel.
It'’ 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.
NOTICE
⚫When the reading of the load power on the LCD is not correct, please reverse the CT arrow.
⚫The external CT will become available after finishing setting program 12 of F0 group.
