After the SUN2000L is powered off, the remaining electricity and heat may still cause
electric shocks and body burns. Therefore, put on protective gloves and operate the
SUN2000L 5 minutes after the power-off.
If the SUN2000L is connected to the battery, ensure that a shutdown command is sent
from the app. Power off the system after the SUN2000L has shut down. If no shutdown
command is sent from the app, the SUN2000L will shut down after the power grid is
powered off. Then, the SUN2000L will wait for 1 minute and restart (not grid-tied) to
charge the battery, which poses the risk of turning off the DC switch with power.
