It can work with several kinds of lead acid batteries such as flooded type, AGM type,
GEL Type.
When it works with lead acid batteries, please set Capacity Type accordingly.

Press wake up button then a low voltage will be generated on the battery port to wake up
the battery. After the wake-up command succeeds, the battery will continue to be charged
according to the normal charging logic.

This function can meet the demand to quickly charge up the battery.
It only takes effect when the grid is valid, and the grid and PV will quickly charge the
battery with the maximum current.
For lead-acid batteries, the charging stops when the float voltage stops, and exits from
force charge.
For lithium batteries, the charging stops at the maximum SOC, and exits from force charge.

The following is the setting of battery parameters. For different lithium batteries,
the inverter has been set with the optimal battery configuration, and it is recommended
that customers do not modify it without authorization.
For lead-acid batteries, the installer should set it according to the battery type.

Description
Max Charge Curr
Max Grid Chg Cur
Force Curr.Set
Min SOC Set
Max charge current set.
Max charge current set to be charged from grid.
When the battery is discharged to the force SOC, the inverter
will continue to be force charged with this value.
The minimum SOC, the default is 20%, when there is grid
power, the battery will stop discharging when it is set to this
value. If there is a load, PV will charge the battery, and the
grid will supply power to the load.
If the charge form PV+GRID is set, the grid power will also
charge the battery at the same time. The battery has been
charged until it reaches max.SOC. After reaching max SOC,
if there is a discharge trigger condition, it can be discharged.
If there is no discharge trigger condition, it will keep charging.
Max SOC Set
Max discharge SOC set.
Force SOC Set
The value is less than Min SOC Set, and the default is 10%.
When the value is set, the force charge will be automatically
activated, and the battery will be forcely charged according to
the maximum charging current, until it reaches the MIN SOC,
and then the force charge will be exited.
Batt under Volt
The lowest discharge voltage. In the case of off-grid, if the
PV does not drive the load, the PV+ battery has been placed
in Batt_under. After reaching under, if there is PV, the PV is
loaded enough, and the PV is loaded. If the PV is not enough
to load, an error will be reported. If there is no PV, the battery
will provide screen/communication, knowing that the cut-off
voltage of deep discharge is reached, and trigger the
mechanical deep discharge protection.
Batt over Volt
Protect the maximum charging voltage value.
When this value is reached, stop charging the battery.
