Grid (Utility) Connection
5.1 Preparation
NOTE1:
to install a separate circuit breaker for safety consideration. Please use 250VAC/40A
circuit breaker between inverter and AC utility.
NOTE2: The overvoltage category of the AC input is III. It should be connected to the
power distribution.
Although this inverter is equipped with 250VAC/40A fuse, it’s still necessary
Before connecting to AC utility, please install a separate AC circuit breaker between
inverter and AC utility. This will ensure the inverter can be securely disconnected
during maintenance and fully protected from over current of AC input.
WARNING!
appropriate cable for grid (utility) connection. To reduce risk of injury, please use
the proper recommended cable size as below.
It's very important for system safety and efficient operation to use

5.2 Connecting to the AC Utility
Overview of AC Connection Socket
Step 1: Check the grid voltage and frequency with an AC voltmeter. It should be the
same to “VAC” value on the product label.
Step 2: Turn off the circuit breaker.
Step 3: Remove insulation sleeve 10 mm for three conductors. And shorten phase L
and neutral conductor N 3 mm. Refer to chart 1.
Step 4: Connect wires according to polarities indicated on terminal block. Be sure to
connect PE protective conductor ( ) first.

Step 5: Make sure the wires are securely connected.The reference tightening torque
is 0.82 N.m.
5.3 Connecting to the Generator
Step 1: Check the generator voltage and frequency with an AC voltmeter. It should
be the same to “VAC” value on the product label.
Step 2: Turn off the circuit breaker.
Step 3: Remove insulation sleeve 10 mm for three conductors. And shorten phase L
and neutral conductor N 3 mm. Refer to chart 1.
