A smart hybrid energy solution engineered by Könner & Söhnen (Dimax GmbH, Germany)

The K&S Tandem System, combining a DC generator ( KS 24VS-DC, KS 24VM-DC or KS 24VGS-DC)  with the portable power station  KS3000PS or DC generator ( KS 48V-DC, KS 48VS-DC, KS 48VGS-DC) with the portable power station  KS5200PS, delivers a fully automated, fuel-efficient, and silent energy supply for homes, small businesses, telecom sites, and mobile applications. The DC generator starts only when the battery is discharged, keeping operation quiet and the air clean while maximizing the use of stored energy. No idle running - no wasted fuel.

When paired with solar panels, the Tandem System relies primarily on renewable energy, using the generator only when absolutely necessary. This creates a seamless energy ecosystem that operates autonomously, maintaining a stable power supply even during outages, peak loads, or unstable grid conditions.

Advanced Hybrid Technology

• Smart automatic operation – the system switches between battery, generator, and solar input without user intervention.

• Fuel-saving DC generator logic – activates strictly on demand for charging, extending runtime and reducing operating costs.

• Scalable power – add extra batteries or a second station to extend operating time or adapt to higher energy needs.

• LiFePO₄ battery technology – long cycle life, enhanced safety, and stable performance in all conditions.
