Peak Shaving Mode
For on-grid status, there are four work modes: Self Use, Feed-in
Priority, Backup and Manual and Peak Shaving Mode.
Self Use
The self use mode is suitable for areas with
low feed-in subsidies and high electricity
prices.
The power of PV will supply the loads rst,
and surplus power will charge the battery,
then the remaining power will feed into
the grid.
Feed-in priority
The feed-in priority mode is suitable for
areas with high feed-in subsidies, but has
feed-in power limitation.
The power of PV will supply the loads rst,
and surplus power will feed into the grid,
then the remaining power will charge the
battery.
The backup mode is suitable for areas
Backup mode
with frequent power outages.
This mode will maintain the battery
capacity at relatively high level, to
ensure that the emergency loads can
be used when the grid is off.
Same working logic with "self use"
mode.

Manual
This work mode is for the after-sales team to do after-sales maintenance.
Manual mode, there are three options to choose from: forced
charging, forced discharge, stop charging and discharging (grid-
connected power).

The D-A period is the battery charging period during which discharging is not
allowed and the PV will charge the battery rst for peak shaving. The ChargeFromGrid"
setting determines whether or not to charge from the grid. When "ChargeFromGrid"
is set to "Disable", the battery cannot charge from the grid; when "ChargeFromGrid" is
set to "Enable" and the actual battery SOC is less than "Max_SOC", the battery will
charge from the grid at no more than "ChargePowerLimits" power.
In the A-B and C-D periods, if the power of loads does not exceed "PeakLimits",
the PV will charge the battery rst. When the battery is fully charged, the PV will
charge loads, and the surplus power will feed into the grid. If the power of loads
exceeds "PeakLimits", the PV and battery will discharge energy for loads and thus
reduce the amount of energy purchased from the grid.
In the B-C period, the battery does not discharge. The PV will charge the battery
to the "Reserved SOC" rst and then supply power for loads, with the surplus
power feeding into the grid. Charging the battery rst in these periods is storing
energy for the peak shaving.
* If there are requirements for zero output from the inverter, the PV output will be
limited.
