Details

Specification

Nominal power, kW:	3.3
Engine start:	auto / external control (gasoline only)
Voltage, V:	50-55

Benefits

Backup charging device – designed for battery-based power systems with an operating voltage range including 50–55V.
Supports dual fuel types (gasoline/LPG) – The generator can be operated with both gasoline and LPG (propane, butane, and their mixtures). This allows switching to a cheaper, longer-lasting gas after startup.
Automatic operation – in AUTO mode, the generator independently monitors the battery voltage, starts when it drops below 50V, and stops when the output reaches 54.5 ± 0.5 V and the current drops below 20A.
EXTERNAL CONTROL mode – generator starts/stops via CONTROL TERMINAL contacts, regardless of battery voltage or output current.
Soundproof housing – significantly reduces the noise level during operation and thus reduces ambient noise pollution.

Delivery

Dear Customers,

Due to ongoing attacks in the region where our warehouse is located, as well as systematic power outages, the processing and shipping of orders may currently take up to 3–5 days.

Features

The KS48VGS-DC DC generator, 50–55V version, from Könner & Söhnen is designed for charging batteries in the 50–55V range, particularly LiFePO₄ with a nominal voltage of 51.2V, as well as other types that allow a charging voltage of up to 55V. It is ideal for 48V-based energy systems such as solar, wind, and telecommunications systems. It operates in AUTO and EXTERNAL CONTROL modes and supports control via dry contacts. Equipped with short-circuit, overload, and overvoltage protection, it starts from the battery being charged. It features wheels, a handle, a EURO 5 motor, and an alternator with copper windings.

Dual-fuel engine (gasoline/LPG)

The generator supports operation with two fuel types: gasoline and liquefied petroleum gas (LPG). The dual-fuel system allows you to choose the most economical and cost-effective option depending on the operating conditions.

Backup battery charger

designed for power systems with battery storages with operating voltage range of 50–55 V

AUTO and EXTERNAL CONTROL modes

AUTO: The generator automatically monitors the battery voltage; EXTERNAL CONTROL: The generator starts and stops by closing and opening the CONTROL TERMINAL contacts.

Soundproof housing

significantly reduces the noise level during operation and thus reduces ambient noise pollution.

User-friendly control panel

ergonomically designed, with all necessary displays and controls for easy operation. The mode switch allows for quick adjustment to user requirements, and clearly labeled elements ensure intuitive use.

Powerful and economical engine

equipped with a modern engine that complies with the EURO 5 standard. Thanks to an optimized combustion system, it offers high performance with minimal fuel consumption. This makes the unit efficient, economical, and durable.

Monitoring of all important operating parameters

automatic shutdown when the oil level is low, protection against reverse polarity and short circuits, and a fuel level sensor.

Benefits

High power (up to 3.3 kW)

generates a charging current of up to 60 A at a voltage of up to 55 V

Dual-fuel engine (gasoline/LPG)

Ease of use

The ability to choose between AUTOMATIC and EXTERNAL CONTROL modes allows you to adapt the generator to different usage scenarios, ensuring autonomy in the event of a power outage.

Engine protection

Thanks to the low-oil sensor, the engine stops if the oil level is too low, thus protecting it from serious damage. The generator's ammeter is equipped with an hour meter to ensure timely maintenance.

Operational safety

The generator is equipped with a control system that protects it against overloads, short circuits, and excessive battery voltage.

Efficiency and durability

The 4-stroke engine complies with the EURO V standard and ensures optimal fuel consumption, as well as the longevity of the generator and stable operation under various operating conditions.

ATTENTION! The product is sold without engine oil or gasoline. Before the first start, engine oil for four-stroke gasoline engines must be added. We recommend 10W-30 or 10W-40 oil. Always check the oil level before each use. Use only unleaded gasoline with an octane rating of 90–95 containing no more than 10% ethanol.
