Inverter battery generators
Meet the Könner & Söhnen KS 3000PS and KS 5200PS models – advanced all-in-one power units that give you true energy independence and comfort
K&S power unit intelligently draws energy from any available source and seamlessly switches between 4 charging methods to stay charged:
Technical Highlights
Each station comes equipped with an ultra-durable lithium iron phosphate battery (LiFePO₄) rated for 6,000+ cycles. That's over 10 years of daily use without significant capacity loss
Charge up to 80% in as little as 1-2 hours. With dual input charging and an advanced MPPT controller, you can replenish the battery insanely quickly and be back to full power in no time
The system grows with you. Hook up an extra external battery or even connect a second unit to double your capacity with minimal effort
In case of grid failure, power switches almost instantly. Your router, computer, server, smart home system won't even notice the outage and will be reliably protected
Smart Battery Management System (BMS) is a multi-level battery monitoring system that controls charge level, temperature, charging speed, and capacity. It protects against faults like overcharging, and balances cells to ensure long, safe, and reliable operation
Delivering up to 3000W (3 kW) of continuous AC power for the 3000PS (and a massive 5200W for the 5200PS), these stations can handle heavy loads and sensitive appliances – everything runs just as if it were grid power
Dry contacts allow the power station to automatically signal a connected generator to start or stop when charging is needed. The ATS (Automatic Transfer Switch) instantly switches your home between grid and backup power in case of an outage
