6 System Operation
This chapter describes the SUN2000 power-on and initialization process.
6.1 Checking Before Power-On
To ensure normal SUN2000 operation, check the SUN2000 before powering it on.
Before powering on the SUN2000, check that:
1. The SUN2000 is installed correctly and securely.
2. The PGND cable is securely connected.
3. All AC output power cables are securely connected.
4. All DC input power cables are securely connected.
5. Idle DC input terminals are protected with sealing caps.
6. Idle USB and RS485 ports are blocked with waterproof plugs.
6.2 Powering On the SUN2000
Power on the SUN2000 after electrical connections are completed.
Procedure
Step 1 Switch on the AC circuit breaker between the SUN2000 and the power grid.
If Step 2 is performed before Step 1, the SUN2000 reports a fault about abnormal shutdown
on the LCD. Start the SUN2000 only after the fault is automatically rectified. This takes a
default clearance time of 1 minute. The clearance time can be modified using LCD or the
network management software running on a PC connected to the SUN2000.
The monitoring panel is activated only after power is supplied to the DC or AC side.
