Könner & Söhnen KS 5200PS portable power station

The Könner & Söhnen KS 5200PS portable power station is a powerful 3-in-1 mobile power station that combines a pure sine wave inverter, an MPPT solar charge controller and a 5120 Wh LiFePO4 battery. The model is designed for off-grid power supply to homes, offices, businesses, workshops, holiday homes, technical rooms or facilities where a large energy reserve and a stable backup power supply are required.

The Könner & Söhnen KS 5200PS has a rated power of 5200 W, making it suitable for powering significantly more demanding equipment than compact charging stations. It can be used for lighting, computers, routers, communication systems, CCTV, office equipment, fridges, pumps, boilers, tools, chargers and other loads within the permissible load range.

The station is built around a LiFePO4 battery with a capacity of 5120 Wh, or 100 Ah. The battery’s nominal voltage is 51.2 V. This energy reserve makes the model a practical solution not only for short power cuts but also for longer periods of autonomous operation, when it is necessary to maintain power to critical systems for many hours.

The lithium iron phosphate battery is designed for long-term use and has a lifespan of up to 6,000 cycles under conditions of 0.2 C charging and 0.5 C discharging at 80% DOD. It is also rated for up to 4,000 cycles at a 0.5 C charge and 0.5 C discharge rate at 80% DOD. This makes the KS 5200PS a reliable investment in energy independence for the home, business or off-grid system.

One of the model’s key advantages is its UPS function. In the event of a mains power failure, the unit automatically switches the connected load to the battery. The switchover time is 10 ms in UPS mode or 20 ms in VDE4105, Home and GEN modes. This helps protect sensitive equipment from sudden power cuts, reduces the risk of data loss and maintains the continuous operation of critical systems.

The inverter’s output voltage is 230 V ±5%, the frequency is 50 Hz, and the output waveform is a pure sine wave. As a result, the unit is suitable for powering sensitive electronics, computer equipment, pumping equipment, boilers, power supplies, office equipment and other devices for which stable power quality is essential.

For connecting AC equipment, there are 4 Schuko 230 V sockets and an additional connection on the rear panel. This allows you to power several devices simultaneously or integrate the unit into a more complex uninterruptible power supply system. The current at the AC outputs is rated up to 120 A.

For DC devices, the model has two 12 V DC5521 outputs. For mobile electronics, there are 4 USB Type-A 5 V/2 A and 1 USB Type-C 5 V/2 A ports. This range of outputs allows you to connect household appliances, network equipment, lighting, chargers, gadgets and auxiliary DC devices simultaneously.

The KS 5200PS supports four power supply and charging methods: mains, solar panels, an external battery and a DC generator. This makes it a fully-fledged component of a hybrid power system, rather than simply a large charging station. The user can select the power source depending on the situation, the availability of the mains, solar generation or a backup generator.

An MPPT controller with a maximum efficiency of up to 98% is used for solar charging . The MPPT voltage range is 150–430 V, and the maximum DC open-circuit voltage is 450 V. The maximum PV charging current is 100 A. These parameters allow for efficient operation with solar panels and rapid replenishment of energy reserves under favourable conditions.

The station supports fast solar charging to 80% in approximately 1 hour. This is important for off-grid scenarios where you need to quickly recharge the battery using solar energy and minimise dependence on the mains grid. Combined with a large 5.12 kWh battery, this provides a good reserve for extended operation.

A distinctive feature of this model is the 48V DC output for a generator or an additional battery. The station is compatible with Tandem Power technology and can operate in conjunction with a KS 48V-DC generator. When the battery charge level drops, a compatible generator can start automatically, operate at maximum efficiency and switch off once the station is recharged.

The ability to connect additional batteries or two identical units, for example 2×KS 5200PS, creates a flexible, scalable system for the home, business or emergency backup. This is useful in situations where greater autonomy, a larger energy reserve or longer operation without constant user intervention is required.

The station’s efficiency is 90%. This helps to make effective use of stored energy and get more useful work out of the battery. For a powerful station of this class, efficiency is of great importance, as it directly affects the actual runtime.

An LCD display is provided for monitoring parameters. It helps to keep track of operating status, charge level, modes and key system indicators. A USB cable connection to a computer is also provided, which is useful for monitoring and configuration.

The unit features overload and overheating protection. This is important when operating under high loads, when connecting multiple loads simultaneously, or when using the unit as a backup power source for critical systems. This protection helps preserve battery life and ensure the stability of the entire system.

Despite its large capacity and high power output, the Könner & Söhnen KS 5200PS remains a portable solution. The model is equipped with wheels and carrying handles, making it easier to move around the home, workshop, office, warehouse or technical room. The net dimensions are 485×280×630 mm, and the net weight is 56 kg.

The kit includes the power station, a USB cable for connecting to a computer, a GX20 plug for the ATS output, two 120 A plugs for 48 VDC connection, two MC4 connectors for the PV input, and an instruction manual. This configuration is designed for use as part of a hybrid system with solar panels, a DC generator or additional power sources.

The Könner & Söhnen KS 5200PS portable power station is a powerful energy hub for demanding tasks. It combines 5200 W of power, a 5120 Wh LiFePO4 battery with a lifespan of up to 6000 cycles, UPS, MPPT, pure sine wave, 4 x 230 V sockets, Tandem Power support, a 48 V DC output, compatibility with additional batteries, an LCD display, and wheels and handles for transport. This is the solution for those who need maximum autonomy, high power and the ability to build a flexible backup power system.
