Fault code display:
Step 1: Check the following requirements before commissioning:
Correct wire connection.
Ensure all breakers in Line wires of load side are open and each Neutral wire of
each unit is connected together.
Step 2: Turn on each unit and set “enable parallel for output” on SolarPower or
SolarPower Pro. And then, shut down all units.
Step 3: Turn on each unit.
NOTE: Master and slave units are randomly defined. Warning 02 is AC GRID voltage
low.
Step 4: Switch on all AC breakers of Line wires in AC input. It’s better to have all
inverters connect to utility at the same time. If not, it will display fault 82 in
following-order inverters. However, these inverters will automatically restart. If
detecting AC connection, they will work normally.
