Maintenance

8.1 System Power-Off

Precautions

WARNING

After the SUN2000 powers off, the remaining electricity and heat may still cause

electric shocks and body burns. Therefore, put on protective gloves and begin

operating the SUN2000 five minutes after the power-off.

Procedure

Step 1 Send a shutdown command on the app.

Step 2 Turn off the AC switch between the SUN2000 and the power grid.

Step 3 Turn off the DC switch at the bottom of the SUN2000.

Step 4 (Optional) Install the locking screw for the DC switch.

Figure 8-1 Installing the locking screw for the DC switch

Step 5 Turn on the DC switch between the PV string and the SUN2000 if there is any.
