7.2 Working Mode Introduction
7.2.1 Standby Mode
In this mode, the machine will not run and is in a waiting state. At this time, the converter will continue to accept instructions or detect system parameters, and when conditions permit or settings are changed, the system will try to enter the working mode state.

7.2.2 Default Operating Mode
The default operating mode of LSP100K is as follows:

  1. The about output terminal outputs to the photovoltaic inverter according to the default 12 channels of 100kW, and the Vin input terminal performs MPPT tracking on the input photovoltaic string and tracks the maximum photovoltaic power generation energy sent to the battery.
  2. When the PV input energy is greater than 100kW (the default output power of PVout), the excess energy will be stored in the battery, and the battery capacity will increase.
  3. When the energy input by PV is less than 100kW (the default output power of PVout), the excess energy will be discharged from the battery, and the capacity of the battery will decrease.
  4. As in article 2 above, if it continues until the battery is fully charged, the system will automatically reduce the PVin input power to a basic equilibrium state with the PVout output power, and maintain a power output of 100kW.
  5. As in article 3 above, if it continues until the battery discharges, the system will automatically reduce the about output power to slightly less than the PVin input power to keep the battery from entering a power deficient shutdown state

7.2.3 fault Mode
The converter’s intelligent control system will continuously monitor and adjust the state of the system. When the converter detects any failure, the alarm or failure LED indicator lights up or flashes red, and the corresponding failure information display can be viewed on the LCD.

7.2.4 Programming Mode
Converter updates the program mode. In the initial stage, the machine will download the program into the storage unit of the converter, and then enter the program update state, and the machine will not work in the program update state.
7.2.5 Turn Off Mode
When the battery is turned off and the sunshine is very weak, the converter will automatically stop working, and the converter’s display system will also shut down at this time. At this time, the machine will not consume the energy of the PV string and battery.

7.3 Trail Running Step

  1. Turn on the PV switch of the PV inverter in the system to ensure that the energy at the PVout output end of the LSP100K can enter the PV inverter. As shown in picture 6.3 above, path “3” is turned on.
