Why Choose All-in-One Power Units?
From Stormy Nights to Off-Grid Weekends
When the lights go out at home, they instantly keep your essentials running — lights, refrigerator, Wi-Fi — without disruption. In your home office, they work as a silent UPS, protecting your workflow from sudden outages. Power a garden house or workshop far from the mains, running tools and lighting without noisy generators or long cables. And at a remote cabin, store solar energy by day and enjoy modern comfort at night — with automatic backup ready whenever nature needs a little support.
Technical Highlights
6000+ Charging Cycles
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
Fast Charge
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
Plug-and-Play Expandability
The system grows with you. Hook up an extra external battery or even connect a second unit to double your capacity with minimal effort
Ultra-Fast UPS Switching (<10 ms)
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 BMS
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
3-5.2kW Inverter Power
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 & ATS
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
