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 or loads, with
the surplus power feeding into the grid. Charging the battery rst in these
peiods is storing energy for the peak shaving.
Peak shaving mode is set for leaving out peaks in electricity use.
Peak shaving mode
* If there are requirements for zero output from the inverter, the PV output will be
limited.
