6.4 Battery Connection
Charging & discharging system of X3-Hybrid series inverter is designed for
high-voltage lithium battery.
Before choosing battery, please note the maximum voltage of battery can not
exceed 500V and the rated voltage of battery can not exceed 400V, and the
battery communication should be compatible with X3-Hybrid inverter.
.
Before connecting to battey, please install a nonpolarized DC breaker to make sure
inverter can be securely disconnected during maintanance.

Step2. Insert the stripped cable up to the stop ( negative cable for DC plug(-) and
positive cable for DC socket(+) are live). Hold the housing on the screw
connection.
Step3. Press down spring until it clicks audibly into place.(it must be possible to
see the fine wire strands in the chamber)
Step1. Choose the 9 AWG wire and strip the cable to 15mm.
Communication interface bewteen inverter and battery is CAN with a RJ45
connector.

Note！
The battery communication can only work when the battery BMS is
compatible with the inverter.
Step4. Tighten the screw connection(tighten torque:2.0Nm)
