Powering On the SUN2000:
Before turning on the AC switch between the inverter and the power grid, use a multimeter to check that the AC voltage is within the specified range.
Procedure
Step 1 Turn on the AC switch between the inverter and the power grid.
Step 2 Turn on the DC switches at the bottom of the inverter chassis.
Step 3 (Optional) Measure the temperatures at the joints between DC terminals and connectors using a point-test thermometer.
To ensure that the DC terminals are in good contact, check the temperatures at the joints between DC terminals and connectors after the SUN2000 has been running for a period of time. Ensure that the temperature rise does not exceed 40°C.
Step 4 Connect with SUN2000APP as advanced user and check the inverter status
