INVT BD Series User Manual

Introduction Introduction
3.2 Work Modes
BD series inverter provides multiple work modes based on different
requirements.
Work modes: Self-use (without PV Power)
When no PV supplied, battery will
discharge for local loads firstly, and
grid will supply power when the battery
capacity is not enough.
EPS Status
When the grid is off, system will supply
emergency power from PV or battery to supply
the home loads. (Battery is necessary in
EPS mode.)
Work modes: Feed in Priority
Priority: load>grid>battery
This mode applies the area that has high
feed-in tariff and export control.
The PV generated power will be used to
supply the local loads firstly, then export
to the public grid. The redundant power will
charge the battery.
Work modes: Back up mode
Priority: battery>load>grid
This mode applies the area that has frequent
power outages. And this mode ensures the
battery will has enough energy to supply when
the grid is off
.
In this mode battery will be charging
forcibly in the setting time and will never
be discharged when the grid is on, and it
also allows to choose whether charge from
the grid or not.
Work modes: Self-use (with PV Power)
Priority: load>battery>grid
This mode applies the area that has low
feed-in tariff and high energy price.
The power generated from PV will be used to
supply the local loads firstly, then to
charge the battery. The redundant power
will export to the public grid.
Work modes: Force time use
Priority: battery>load>grid(when charging)
Priority: load>battery>grid(when discharging)
This mode applies the area that has
electricity price between peak and valley.
User can use off- peak electricity to charge
the battery.
The charging and discharging time can be
set flexibly, and it also allows to choose
whether charge from the grid or not.
