Micro-grid (PV-ESS-DG Power System):
A generator is connected to the GEN port:
If the grid power is normal, the WIT inverter will work in the grid-tied mode:
1. If the power generated by the grid-tied inverter is sufficient to support the loads,
the surplus power will be used to charge the battery;
1. The solar power of the WIT inverter is supplied to the loads first, and the surplus
power is sent to charge the battery.
2. If the power generated by the grid-tied inverter is insufficient, the WIT inverter
will supply the solar power to the loads, and direct the surplus power to charge
the battery.
If the grid power is abnormal, the WIT inverter will work in the off-grid mode:
3. If the solar power of the WIT inverter is insufficient, the battery will discharge to
power the loads.
2. If the solar power of the WIT inverter is insufficient, the battery will discharge to
power the loads.
4. The battery will stop discharging when the SOC is lower than the cutoff
threshold and it will draw the grid power to support the loads.
4. If charging from the DG is enabled, the DG will charge the battery.
3. When the battery SOC is lower than the preset diesel generator startup
threshold, the DG will start automatically to generate power;
5. When the battery SOC is higher than the preset diesel generator shutdown
threshold, it will disconnect the DG, and shut down the DG.

User-defined dry contact:
After enabling the user-defined DI port and inputting the DI signal, it will carry out
the AC active power and power factor according to the corresponding DI
instructions.
Note:
1. The User-defined dry contact and DRMS share the same port.
2. Only one DI signal can be input at the same time.
7.2.3 Fault Mode
The intelligent control system of the WIT Inverter monitors and adjusts the system
status in real time. When the WIT Inverter detects an alarm, the corresponding
status light will turn red and the OLED will display the alarm. When the WIT
Inverter detects a fault, the system status indicator and the corresponding status
light will turn red and the OLED will display the fault. After the fault or alarm is
cleared, the system recovers and all status indicators will be steady green.
NOTE: For details about faults and alarms, please see 9.2 Troubleshooting.
7.2.4 Shutdown Mode
When the battery SOC is lower than the discharge cutoff SOC and the PV string
output power does not meet the requirements for grid-tied power generation, the
WIT Inverter will automatically shut down. In shutdown mode, the inverter still
consumes a bit energy (PV>Grid>Battery) to wait to start up again when the
operating requirements are met.
NOTE:
When the DC input voltage is less than or equal to 150Vdc or the battery voltage is
lower than 600V, the WIT Inverter enters the shutdown mode automatically.
