(Keep the Battery at a certain SOC and only use it during power outage):
Backup SOC Setting Range: From Battery “Overdischarge SOC” to 100%
PV Power Using Priority: Battery>Load>Grid
Load Support Priority: PV>Grid>Battery
Battery Charging Power comes from PV.
(If “Charging from Grid” is allowed, it can also come from Grid)
*The “Backup Mode” is not applicable for Lead-acid batteries.

NOTE:
Unless specially required, it is suggested to keep the "Charging from Grid"
as "Allow". If it is set to "Not Allow", the battery force charging logic will be
affected and may lead to a fully discharged battery.

5.6.5.3 Battery Wakeup

.
This function should be activated only after the installation
In the case of a low battery
voltage shutdown, the inverter will shut-down. This setting can be enabled, so when the
inverter detects PV or grid it wakes up the battery.
This function conflicts with the battery
reverse polarity protection( If the installer connects cables with wrong polarity the inverter
,
can protect itself from damage).To avoid the possible damage during installation do not
,
activate battery wakeup function before finishing the first commissioning.
