3.2 Positive/Negative wires of storage battery
There is no reverse connection protection for the input, check if the Positive and Negative are
connected correctly before connecting, or the inverter may be damaged!

3.3 AC device
1) The device has two AC output interfaces. Connect the load device to the following 3P terminals if
the power of a single load device is higher than 70% of the rated power, defined as follows:
Single strand copper wire with a wire diameter less than 4 mm

is recommended;
Add soldering tin to the wiring place to make it integral and insert it into the corresponding hole if
multiple strands of wire are used;
Please connect the ground wire first, then the fire wire L and zero wire N.
Stop the inverter to remove the wiring, then use a sharp tool to insert the small hole above the interface
and pull out the connecting wire by force.

2) The inverter is equipped with a standard American-Standard terminal, as shown in the drawing below,
with a maximum current capacity of 20A.
When the battery voltage is higher than the input voltage of over-voltage protection, turn off the AC output, and
the fault indicator lamp and buzzer will prompt; When the battery voltage is lower than the input voltage (1V)
of over-voltage protection, the AC output is recovered.
Step 4: Start the inverter
4.1 Close the circuit breaker at the inverter's DC input terminal or the fuse at the battery;
4.2 Short circuit the inverter's external switch contact interface (short-circuited for factory);
4.3 Set the inverter's mode switch to ON to start the inverter output: The running indicator is always green,
and AC power output is normal;
4.4 Close the circuit breakers on the AC load line, turn on the AC load one by one, and check the operating
status of the inverter and the load;
4.5 If the fault indicator is red with a buzzer alarm after starting the inverter, please turn off the load and
inverter and refer to Common Problems and Solutions for troubleshooting. Repeat the preceding steps after
the fault is rectified.

Although the inverter has an input of overvoltage protection, the input voltage of the 12 V system shall not be
higher than 20 V; The 24 V system input voltage shall not be higher than 35 V, otherwise, the inverter may be
damaged.

When the battery voltage is lower than the input voltage of low-voltage protection, turn off the AC output, and
the fault indicator lamp and buzzer will prompt; When the battery voltage is higher than the input recovery
voltage of low-voltage protection, the AC output is recovered.

The AC output has three automatic recoveries for inverter's overload protection (the first time delay is 5S,
the second time delay is 10s, and the third time delay is 15s). The AC output will not automatically recover
at the fourth time until restarting the inverter after checking the device and removing the faults.
