KT-LFPES512100
Before connecting the battery with inverter.make sure the following rules are complied.
1. The battery system discharge power/current is proper with the inverter power. It is recommended to congure the inverter
capacity with battery in 1: 2 proportion, for example. If you have a 5 kW rated inverter, connect at least 2 batteries (10kWh),
2. If the system is an off-grid system, make sure that conguration can manage to avoid overdischarging the battery. It is strongly
recommended to install a smart generator and MPPT modules (brands like Victron that support DC-coupled application).
3. Make sure that the installation environment, setting and sequence is following the User Manual.

2.1.3 INVERTER SETUP
1 Check the inverter screen, if green LED is on, and there is no alarm LED, it means that everything is proper, otherwise please check
inverter manual for troubleshooting.
2 Click the setting icon on the screen top right and choose battery setting
3 Enter the Battery Setting and set the following values
If we congure the inverter with the battery connected via the CAN communication cable (inv. BMS CAN, Master battery Link In) we
set the following parameters (in each window, press the button to conrm the parameters, otherwise the settings will not be set):
Battery Setting:
Batt Mode: Lithium
Batt Capacity: 100Ah * N (N indicates the number of battery pack in parallel )
Max A charge: 50A * N (N indicates the number of battery pack in parallel )
Max A discharge: 50A * N (N indicates the number of battery pack in parallel )
Activate battery: enable
Lithium mode: 00
Shutdown: ≥ 10%
Low batt: ≥ 20%
Restart: ≥ 30%
Grid charge: enable
Gen charge: enable (if using Diesel generator)
However, if we congure the battery WITHOUT connection with a communication cable by the CAN port, enter the settings manually:
Batt mode: Use Batt V
Max A charge: 50A * N (N indicates the number of battery pack in parallel )
Max A discharge: 50A * N (N indicates the number of battery pack in parallel)
Activate battery: enable
Shutdown: ≥ 10%
Low batt: ≥ 20%
Restart: ≥ 30%
Grid charge: enable
Gen charge: enable (if using Diesel generator)
Float V: 54,6V
Absorption: 56,0V
Equalization V: 56V
Equalization Days: 15 days
