Manual
This work mode is for the after-sales team to do after-sales maintenance.
For off-grid status, there is only one work mode: EPS (Off-grid).
Priority: Loads > Battery > Grid
The back-up mode is suitable for areas
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.
* For the above three work modes, when the power of PV is insufficient
to supply the loads, the battery will supply the loads. If the battery is
insufficient, then the grid will supply the loads.
EPS (Off-grid)
①
②
Priority: Loads > Battery
In case of power failure, the system will
supply EPS loads through PV and battery.
(The battery must be installed, and EPS
loads shall not exceed battery’s max.
output power.)
The power of PV will charge the loads rst,
and surplus power will charge the battery.
Note:
The battery will stop discharging when SOC=min SOC. But due to
battery self consumption, sometimes SOC may < min SOC.
For on-grid status, if the battery SOC ≤ (min SOC-5%), the inverter will
take utility energy to charge battery SOC back to (min SOC+1%).
For off-grid status, if the battery SOC ≤min SOC, the inverter will be
unable to enter EPS mode (the battery will be unable to discharge
unless SOC is back to 31%.)
Peak shaving mode is set for leaving out peaks in electricity use.
Peak shaving mode
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.
