Warning: Before making the battery connector, please make sure the polarity of the cable is correct.

Warning: Use a multimeter to measure the voltage of the battery pack and make sure the voltage is within the inverter 
limitation and the polarity is correct.

AC output connector connection

The following principles must be considered when making AC output connection.

1) An independent AC breaker is required in both inverter on-grid and back-up output side, and any loads cannot be connected 
with inverter directly.

2) Before making the connection of AC cable, please confirm all DC & AC power source are disconnected from the inverter.

3) The M-TEC Energy Butler three-phase high voltage hybrid inverter applies to the three-phase power grid with a voltage of 
230/400V and a frequency of 50/60Hz.

AC connector assembly procedures

The recommended AC cable and AC breaker for M-TEC 10kW three-phase hybrid inverter are as shown in the table.

6) Insert the positive and negative connector into the inverter battery terminals respectively, and a “click” sound represents the 
assembly in place.
