System Switch
d) “System Switch” can be selected from “ON” or “OFF”.
“ON” means the inverter is on working condition and is the default status.
“OFF” means the inverter stops delivering all power, but the LCD remains on.

c-6) ARC-Detection
There are two options: YES or NO. An AFCI module is inside of the inverter. When an
arc fault occurs in the DC circuit, the inverter will shut down and the Fault message
will be displayed which can only be removed manually. Please check the DC cables
and connections to identify the source of possible arcing. Then select "Reset ARC"
and "YES", the inverter will restart.
The "self test" is a manual test function.
When the "self test" function is enabled, the arc detection self test function will be
carried out.

Demand Mode
For “Demand Mode”, there are some parameters can be set.
DisChgPwrThr: This is the power threshold obtained from the grid, the
range is 0W to 6000W, the default is 2000W.
ThrRate: This is the ratio of adjust the threshold. It works in conjunction
with the power threshold obtained from the grid. The range is 1% to
100%, and the default is 95%.
DisChgStartTimeP1: The starting time of the discharge period P1, and
the default is 7:00.
DisChgEndTimeP1: The ending time of the discharge period P1, and the
default is 9:00.
DisChgStartTimeP2: The starting time of the discharge period P2, and
the default is 17:00. The starting time have to be later than the ending
time of discharge period p1.
DisChgEndTimeP2: The ending time of the discharge period P2, and the
default is 19:00.
ChargeMaxCapP3: The charging capacity that required by the period P3.
The range is 10% to 100%, and the default is 50%.
ChgFlagP3: It can be set Enable or Disable. If it’s Enable, when the
current battery capacity is lower than the ChargeMaxCapP3, the battery
will be charged from the grid.
PowerLimitP3: This is used to limit the charging power of the period P3.
The range is 0W to 6000W, and the default is 3000W.
Divide the day (in military format (24H)) into four periods, as shown below:
2. On the period 3 (P3), the battery can be charged and can not discharge,
through judging whether to set the ChgFlagP3 and whether the current
battery power is greater than the ChargeMaxCapP3; When the battery power
is lower than the ChargeMaxCapP3 and the ChgFlagP3 is Enable, the battery
will be charged from the grid; an upper limit can be set for the PowerLimitP3
at this stage.
3. The battery can only discharge during the period 1 (P1) and the period 2
(P2). The battery will discharge when the power from the grid is greater than
the DisChgPWRTHR.
4. The battery can only be charged in the period 4 (P4), when the PV power
priority to provide the load supply, and then to charge the battery, if there is
surplus PV power, it will feed in the grid.
