Kon-TEC KT-LFPES512100 Lithium Iron Phosphate Lifepo4 Battery Pack Owner’s Manual

Kon-TEC KT-LFPES512100 Lithium Iron Phosphate Lifepo4 Battery Pack

Product Information

The product is a Lithium Iron Phosphate (LiFePO4) battery pack with a capacity of 51.2V 100Ah. The model number of the battery pack is KT-LFPES512100, and it is manufactured by Kon-Tec. The product can be connected to Victron inverters for power backup purposes.

Product Usage Instructions

1. Preconditions: Before connecting the battery with an inverter, ensure that the following rules are complied with:
   • The battery system discharge power/current is proper with the inverter power. It is recommended to configure the inverter capacity with the battery in 1:2 proportion.
   • If the system is an off-grid system, make sure that configuration can manage to avoid overdischarging the battery. It is strongly recommended to install a smart generator and MPPT modules.
   • Make sure that the installation environment, setting, and sequence follow the User Manual.
2. Commissioning with Inverter: The product can be commissioned with a Victron inverter by following the steps below:
3. Cable Connection: Ensure that both the inverter and battery are completely off. Connect the communication cable to the system according to the schematic provided in the User Manual.
4. Start System:
5. Set the Master battery DIP address according to the User Manual.
6. Press the Master battery reset button to switch on all the batteries and then close the battery breaker.
7. Close the inverter switch, then turn on the DC breaker to start MPPT.
8. Switch on the AC input and output breaker.
9. Inverter Setup:
10. Confirm the firmware version.
11. Choose the baud rate, setting-services, ve.can port, select the 250/500 according to battery User Manual.
12. Locate the battery on the GX device and check the CCL and DCL parameters.
13. Set DVCC as per the instructions in the User Manual.
14. Configure MPPT via Victron connect.

PRECONDITIONS

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 configure 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 configuration 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.

COMMISSIONING WITH INVERTER

VICTRON
Victron devices and Kon-TEC KT-LFPES512100 battery can be used for the following system types:

• Energy Storage Systems (ESS) – Self Consumption
• Grid Backup (DVCC or ESS)
• Off-grid (DVCC)

A GX device is required to establish communication. It is essential to use the CAN-bus connection of the GX device (e.g. Cerbo GX) – communicates the keep- alive signal, charge and discharge limits, error codes and state of charge (SOC %) between the batteries and the system.
The minimum required firmware version for the GX Device is v2.40. It is highly recommended to use the latest firmware version on all connected devices, including the GX device lnverter/Charger and MPPTs.
Both 250Kbps and 500Kbps are supported. If you use a new VE.Can MPPT, it must also be with a GX device that has more than one CANbus interface, e.g. the Cerbo GX.
Compatible device:
Multi, MultiPlus, MultiGrid, EasySolar-II, Inverter RS & Multi RS and Quattro.
VE.Direct BlueSolar and SmartSolar MPPT Chargers.

CABLE CONNECTION

1. Both inverter and battery completely off.
2. Connect the communication cable to the system according to the following schematic.

START SYSTEM

1. Set the Master battery (ONLY!!!) DIP address according to the User Manual (Picture above).
2. Press the Master battery reset button to switch on all the batteries and then close the battery breaker
3. Close inverter switch, then turn on DC breaker to start MPPT.
4. Switch on AC input and output breaker

INVERTER SETUP

Confirm the firmware version

Choose the baud rate, setting-services, ve.can port, select the 250/500 accoring to battery User Manual
