(RS485 & CAN) are provided with the package.The battery side plug is
already crimped, the inverter side please refer to inverter's manual for
the pin definition.

STEP-4:
Hang the battery over the bracket, move the battery close to it,
lower the battery, and make sure the 2 mounting bars on the back
are fixed well with the 2 grooves on the bracket.
Drill holes with electric drill, make sure the holes are deep enough
(at least 50mm) for installation, and then tighten the expansion
tubes.

Press and hold the Power button for more than 2s, the battery light
will flash once, then the LED will light up in turn, and when the top most
running light flashes fast for about 10 times, it means that the system
parallel programming is successful and the battery is running normally.

After installing the fixed battery,
measure the voltage of the positive and negative terminals of
the battery with a multimeter to
determine whether there is a
voltage output, and if so,
STEP-2:
Plug the 2 plugs (to short pin1

Parallel mode：
Note: Different model of batteries cannot be mixed in one system,
any further questions related to the battery versions please
contact our technical team at [email protected].
Connect the ground wire of each battery.
Lead-acid function：
Battery capacity (Ah)
In the above two modes, when operating according to the
corresponding steps, the communication harness between the
battery and the inverter is not connected, and the battery enters
the lead-acid function by default; Both stand-alone mode and
parallel mode have lead-acid function.
When the battery uses the lead-acid function, the matching
inverter needs to be set to lead-acid mode as well, and the
following parameters need to be set on the inverter:
Charging voltage (V)
Charging protection voltage (V)
Float voltage (V)
Maximum charging current (A)
Discharge cut-off voltage (V)
Maximum discharge current (A)
Forced charging voltage (V)
Battery internal resistance (mΩ)
Note: Under the lead-acid function, the battery does not
communicate with the inverter, and the inverter will not display the
SOC information of the battery.
Note: Parallel mode supports up to 4 batteries in parallel.
