BACKUP MODE 1
Both AC input and PV input are absent. The backup power to load comes only from
battery. The backup time is determined by the capacity of battery.
BACKUP MODE 2
AC input is absent and PV power
is present, if PV power
is not enough to support
loads completely. The insufficient power is covered by battery.
The larger the PV power, the less consumption from battery and therefore the
longer backup time.
BACKUP MODE 3
AC input is absent and PV power
is present, if PV power
is strong enough,
it will
to not
only support the load but also charge the battery.
As long as the PV power persists, the load can be powered continuously without
consuming power from battery.
