Check Item
If the AC is on and the battery is off, the SUN2000 will report a Battery Abnormal alarm.
If the DC switch is not turned on within 1 minute after the AC is powered on, the
SUN2000 will report a Device Abnormal alarm and will start normally only after the DC
switch is turned on.
If there is a power grid outage, the SUN2000 will assume a power-off state regardless of
whether sunlight is sufficient or a battery is configured. The LEDs will turn off.
