Warning 1.Before assembling the DC connector, make sure that the cable polarity is
correct.
Warning 2.Use a multimeter to measure the voltage of the DC input string, verify the
polarity of the DC input cable, and ensure that each string voltage is within 1000V.

Inverter battery connection
Lithium battery connector assembly
procedures
The following principles must be considered when making battery connection:
1) Disconnect the AC breaker on the grid side.
2) Disconnect the breaker on the battery side.
3) Turn the inverter DC switch to the “OFF” position.
4) Make sure the maximum input voltage of battery is within the inverter limitation
(180~750V). For 2.3kWh LFP module, the operation voltage range of each battery
module is 60V~87.6V, so usually suggested to series connected 3 to 8 modules.
2) Peel off the DC cable insulation sleeve
for 7 mm.
1) Select an appropriate DC cable.
3) Use a flathead screwdriver to open the
clamping bracket in the connector
.
4) Insert the stripped DC cable to the
battery connector deep enough and toggle
the clamping bracket to make sure it tightly
locked with the stripped cable.
