Introduction
Work mode: Feed-in priority
The Feed-in priority mode is suitable for areas
with high feed-in tariffs, but has feed-in power
limitation.
① When the power of PV is sufficient
The power generated from PV will be used to
supply the local loads firstly, and the excess
power will feed-in to the grid.
PV＞Load, PV
②
The power from PV and battery will be used to
supply the local loads.
If the power is still not enough, the remaining
power will be taken from the grid.
(PV Load, PV + Battery + Grid
③ Without PV power
The power from battery will be used to supply
the local loads firstly. If the battery power is not
enough, the remaining power will be taken
from the grid. The inverter will enter into the
standby state.
(PV=0, Battery+Grid
Work mode: Backup mode
Priority: battery > load > grid
This mode applies to regions with frequent
power outages. This work mode will ensure the
battery
outage.
In this work mode, the battery will be charged
at the set time and will never discharge when
the grid is on ou can also choose whether to
charge from the grid or not.

Work mode: Time of Use mode
The Time of Use mode applies to areas that have
different electricity prices depending on the day,
time and season.
Priority: load > battery > grid (when discharging)
Priority: battery > load > grid (when charging)
The power generated from PV will be used to
supply the local loads first, then proceed to
charge the battery bank. The excess power will
be exported to the public grid.
Charges the battery during two available
charging windows from PV or grid (if enabled),
then functions as in Self-use mode
Work mode: Demand Mode
The demand mode is suitable for the areas with
high Critical Peak Pricing or areas with limited
capacity of distribution transformers.
In this mode, battery discharges during two
discharge windows to limit demand charge (if
enabled) (Similar to Time of Use mode but on
Demand Mode the system will allow grid
consumption up to a threshold limit defined by
the user.)
