Please follow below steps to implement battery connection:
1. Assemble battery ring terminal based on recommended battery cable and terminal size.
2. Connect all battery packs as units requires. It’s suggested to connect at least 100Ah capacity battery for
1-3KVA model and at least 200Ah capacity battery for 4KVA/5KVA model.
NOTE: Please only use sealed lead acid battery or sealed GEL/AGM lead-acid battery.
3. Insert the ring terminal of 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 ring terminals are tightly screwed to the battery terminals.

CAUTION!! Do not place anything between the flat part of the inverter terminal and the ring
terminal. Otherwise, overheating may occur.
CAUTION!! Do not apply anti-oxidant substance on the terminals before terminals are
connected tightly.
CAUTION!! 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: Shock Hazard
Installation must be performed with care due to high battery voltage in series.
AC Input/Output Connection
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 10A
for 1KVA, 20A for 2KVA, 32A for 3KVA, 40A for 4KVA and 50A for 5KVA.
CAUTION!! 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.
WARNING! 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.
Suggested cable requirement for AC wires
Please follow below steps to implement AC input/output connection:
1.
2.
3.
Before making AC input/output connection, be sure to open DC protector or disconnector first.
Remove insulation sleeve 10mm for six conductors. And shorten phase L and neutral conductor N 3 mm.
Insert AC input wires according to polarities indicated on terminal block and tighten the terminal screws. Be
sure to connect PE protective conductor (
→Ground (yellow-green)
L→LINE (brown or black)
N→Neutral (blue)
) first.
4. Then, insert AC output wires according to polarities indicated on terminal block and tighten terminal screws.
Be sure to connect PE protective conductor (
→Ground (yellow-green)
L→LINE (brown or black)
N→Neutral (blue)
) first.

CAUTION: Important
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.
CAUTION: 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.
Please follow below steps to implement PV module connection:
1.
2.
Remove insulation sleeve 10 mm for positive and negative conductors.
Check correct polarity of connection cable from PV modules and PV input
connectors. Then, connect positive pole (+) of connection cable to positive
pole (+) of PV input connector. Connect negative pole (-) of connection
cable to negative pole (-) of PV input connector.
3. Make sure the wires are securely connected.
Final Assembly
After connecting all wirings, please put bottom cover back by screwing two screws as shown below.
