Könner & Söhnen KS LB 48–100 lithium-ion battery

TheKönner & Söhnen KS LB 48-100 is a lithium iron phosphate battery designed for energy storage systems where stability, ample power reserve, compatibility with modern inverter solutions, and the ability to build a more robust domestic or commercial power supply system are key priorities. This model is aimed at users who no longer require just a basic storage unit, but a fully-fledged component of a power system with a substantial capacity reserve.

The battery is based on LiFePO4, which means a long service life, stable operation in cyclic mode and smoother performance within backup or off-grid power systems. This type of battery is well suited for regular daily use, where energy storage and discharge occur continuously, and the system must meet requirements for reliability and predictability.

The KS LB 48-100 has a nominal voltage of 51.2 V and a capacity of 100 Ah, providing an energy reserve of approximately 5.12 kWh. In practical use, this represents a whole new level compared to lower-spec solutions: the battery is better suited to systems with higher loads, longer autonomous operation, and the construction of a more substantial home or hybrid setup with an inverter.

A depth of discharge of up to 95% allows a significant portion of the stored energy to be utilised effectively. This is important not only in terms of the figures in the specifications, but also in real-world daily use: the user receives more usable energy without the need to keep an excessively large reserve in an unused state.

The model supports a recommended charging current of 50 A and a maximum charging current of 100 A, as well as a recommended discharging current of 50 A and a maximum discharging current of 100 A. This set of parameters makes the battery suitable for more intensive operation in systems where not only capacity is important, but also the ability to confidently accept and deliver energy during operation.

One of the key advantages of the KS LB 48-100 is its built-in BMS, which is responsible for monitoring key parameters and protecting the battery. It monitors and balances the cells, manages charging and discharging, and helps control temperature, current limiting and other critical parameters. All this enhances the overall stability of the system and simplifies its integration into modern energy storage solutions.

RS-485, RS-232 and CAN-bus are provided for connection and data exchange. This allows the battery to be integrated into systems with various inverters and the appropriate communication protocol to be configured via the display menu. In addition, the battery supports dry contacts and has separate ports for service configuration and diagnostics.

It is worth noting the possibility of parallel connection. For many users, this is a critical advantage, as energy storage systems rarely remain unchanged for years to come. If requirements increase, the KS LB 48-100 allows you to scale the configuration and increase the total energy capacity without the need to completely replace the existing system.

The battery housing features an LCD display, a charge level indicator, an alarm indicator and a status indicator. This allows you to quickly monitor the system’s operation, view key statuses and respond promptly to changes in parameters. Combined with communication interfaces, this makes the model not just a battery, but a fully-fledged component of a modern energy-saving system.

The KS LB 48-100 measures 700×569×327 mm and weighs 45 kg. It is designed for indoor installation provided the recommended operating conditions are observed. The operating temperature during charging is 0 °C to 45 °C, during discharging – -10 °C to 45 °C, and the storage temperature is 0 °C to 35 °C. When correctly installed and properly integrated into the system, this model becomes a robust core component for a more substantial backup or off-grid power supply.

If you need a battery for a system where not only compactness but also a substantial energy reserve, convenient integration with an inverter, scalability and modern operational control are important, the Könner & Söhnen KS LB 48-100 is an excellent choice. This model is designed for those building a more powerful and forward-looking storage system, intended not for the short term but for stable operation over the long term.
