KJ Power Selects Volvo Penta Battery Systems for its Rental Sector BESS Unit

One of the largest genset manufacturers in Turkey has partnered with Volvo Penta to power its Battery Energy Storage System (BESS), which is designed for mobile energy storage in the rental sector. KJ Power Generator chose Volvo Penta’s integration-ready battery system for energy storage because of the company’s trusted design and engineering expertise.

KJ Power Generator, a prominent company in the global power generator market, has strengthened its business with the addition of its first BESS unit, powered by Volvo Penta’s scalable and adaptable battery systems for energy storage. The 540kWh mobile BESS unit has been designed for the rental segment, where it will be used to power events as well as for grid support. Another potential use case is for reliable charging in industrial applications, such as construction.

Powered by Volvo Penta’s proven, high-performance battery system for energy storage, KJ Power Generator’s BESS unit will help meet the growing demand for zero-emission, low-noise mobile power. The product will initially be aimed at customers in Turkey and Europe.

“We chose to work with Volvo Penta as it’s a trusted supplier with a proven solution and a skilled engineering team,” says Kadir Sümerkent, Vice President at KJ Power Generator. “Volvo Penta has supplied us with engines for our gensets for around ten years, and now we have embarked on the next stage of our partnership together. Volvo Penta engineers made sure the integration of the high-energy-density battery system within the BESS unit was seamless, which helped make our development journey quick and efficient.”

Towards zero-emission and low-noise

KJ Power Generator entered the generator sector in 1996, producing thousands of gensets a year, which are sold in Turkey and exported to more than 90 countries. The company’s first BESS unit was unveiled at its factory in Istanbul, Turkey, on October 15^th 2025. In addition to manufacturing and selling gensets, KJ Power Generator also rents them to customers through its rental business.

“In Turkey, as well as in Europe, we are seeing an increased demand for sustainable, reliable energy,” says Mehdi Kılıç, Volvo Penta’s general manager in Turkey. “Not only will this BESS unit help to secure the power supply at large events where there is an increased demand for energy, but it will also deliver zero-emission power at a very low noise level. This is a very important complementary product to gensets as there is a significant cost involved in soundproofing diesel engine-powered gensets – something which is eliminated with a BESS unit.”

Proven technology

Leveraging the electromobility platform from the Volvo Group, Volvo Penta’s battery system for energy storage offers an energy-dense and compact design. It is certified for mobility and tested with high IP-class protection.

“By extending our partnership with Volvo Penta, we can now offer our customers a flexible, efficient mobile BESS unit that supports the growing demand for low-emission and low-noise energy,” concludes Kadir.
