INSTRUCTIONS FOR CONNECTION
THE BATTERY PACK TO VICTRON INVERTERS
51,2V 100Ah
KT-LFPES512100
Before connecting the battery with inverter.make sure the following rules are complied.
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 rmware version for the GX Device is v2.40. It is highly recommended to use the latest rmware 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.
2.2.1.1. Both inverter and battery completely off.
2.2.1.2. Connect the communication cable to the system according to the following schematic.
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.
