System Power-On
Precautions
- Wear personal protective equipment and use dedicated insulated tools to avoid electric shocks or short circuits.
When LED2 is steady green (meaning that the inverter is grid-tied), do not turn on any DC switch. Otherwise, the inverter may be damaged because the insulation resistance is not detected.
- Before the equipment is put into operation for the first time, ensure that the parameters are set correctly by professional personnel. Incorrect parameter settings may result in noncompliance with local grid connection requirements and affect the normal operations of the equipment.
- Before turning on the AC switch between the inverter and the power grid, check that the AC voltage is within the specified range using a multimeter.
- If the solar inverter has not been running for more than half a year after being mounted, it must be checked and tested by professionals before being put into operation.
- Do not turn the DC switch to the unloaded position
.
- When the system is powered on or running, do not place obstacles (such as cables) to block the rotation of the handle or manually hold the handle. Otherwise, the DC switch cannot be automatically disconnected.
.Procedure
- Turn on the AC switch between the inverter and the grid.
- Set DC SWITCH 1 (MAIN SWITCH) at the bottom of the SUN2000 chassis to ON. When you hear a click sound, the switch is ON.
- Check the status of LED 1. If it is steady green, set DC SWITCH 2 and DC SWITCH 3 to ON.
