3.3.2 Lithium Battery Connection
If choosing lithium battery for 48V Model, you are allowed to use the lithium battery only which have configured.
There're two connectors on the lithium battery, RJ45 port of BMS and power cable.
Please follow below steps to implement lithium battery connection:
1. Assemble battery ring terminal based on recommended battery cable and terminal size (same as Lead acid, see
section Lead-acid Battery connection for details) .
2. Insert the ring terminal of battery cable flatly into battery connector of inverter and make sure the bolts are
tightened with torque of 2-3Nm. Make sure polarity at both the battery and the inverter/charge is correctly connected
and ring terminals are tightly screwed to the battery terminals.
3. Connect the end of RJ45 of battery to BMS communication port of inverter.
4. The other end of RJ45 insert to battery comm port.
Note: if choosing lithium battery, make sure to connect the BMS communication cable between the battery and the
inverter. You need to choose battery type as “lithium battery”
3.3.3 Lithium battery communication and setting
In order to communicate with battery BMS, you should set the battery type to “LI” in Program 5. Then the LCD will
switch to Program 36, which is to set the protocal type. There are several protocals in the inverter. Please get
instruction from the supplier to choose which protocal to match the BMS.
1. Connect the end of RJ45 of battery to BMS communication port of inverter
Make sure the lithium battery BMS port connects to the inverter is Pin to Pin, the inverter BMS port pin assignment
shown as below:

3.4 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 32A
for 3KVA, 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.

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 with manufacturer of air conditioner that if it’s equipped with time-delay function before
installation. Otherwise, this off grid solar inverter will trigger overload fault and cut off output to protect your
appliance but sometimes it still causes internal damage to the air conditioner.
3.5 PV Connection
CAUTION: Before connecting to PV modules, please install separately a DC circuit breaker between inverter
and PV modules.
