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
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 3.84kWh LFP module, the
operation voltage range of each battery module is 60V~87.6V, so usually suggested to series connected 3 to 8 modules for
M-TECH Energy Butler Series.
7) Insert the positive and negative connectors into the inverter DC input terminals respectively, and a "click" sound represents the
assembly in place.
6) Use an open-end wrench to screw the nut to the end to ensure that the terminal is well sealed.
