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.
WARNING: Shock Hazard
Installation must be performed with care due to high battery voltage in series.
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
(-).
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.
