Kon-Tec KT-LFPES512100 Multi Lithium Iron Phosphate Lifepo4 Battery Pack Instruction Manual

PRECONDITIONS

Before connecting the battery with inverter.make sure the following rules are complied.

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),
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).
Make sure that the installation environment, setting and sequence is following the User Manual.

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

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

Kon-TEC Battery BMS CAN port| Victron GX device (VE. CAN Port/ BMS CAN Port)
---|---
Pin 6| GND| Pin 3| GND
Pin 4| H| Pin 7| H
Pin 5| L| Pin 8| L

START SYSTEM

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

INVERTER SETUP

Confirm the firmware version
INVERTER SETUP

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

INVERTER SETUP
