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.

Are you sure?
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.

Are you sure?
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.

Display 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.

Max charge current set.
Maximum current setting for charging from grid.
When the battery is discharged to the force SOC, the inverter
will continue to be force charged with this value.
When there is grid power, the battery discharges to Batt_low,
and the battery stops discharging. 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 is charged
until batt-high. After charging to batt-high, if there is a
discharge trigger condition, it can be discharged. If there is
no discharge trigger condition, it will keep charging.
Batt High Volt
Maximum charge cut-off voltage. When the battery starts
charging from low to high, the battery will not be discharged
to supply power to the load.
Force Volt Set
This value is less than Batt low Volt ,default value is 10% ,
When the value is reached, the force charge will be
automatically activated, and the battery will be charged
according to the force charge current value until it reaches
Batt_low.

Three-stage charging: Float value constant voltage charging,
you can exit when you meet any charging needs.
Three-stage charging: from the beginning of charging to
charging to the Bulk voltage value (the time period is T),
the system keeps charging at this value for a duration of 10T,
after 10T, the voltage drops to the Float voltage value, and
the Float value is constant voltage charging.
You can exit when you meet any charging demand.
Display Description
