The Centauri Energy Server from GreenFox

The modern power management solution

The Centauri Energy Server is a fully-integrated electronics and software platform that can operate as a stand-alone device or integrate into any system through its innovative plug-and-play functionality. Centauri, developed by Kilowatt Labs, can service any load profile (kW to MW) with or without grid access or generator availability.


Centauri is an all-in-one solution that replaces systems comprised of multiple components including PV inverters, charge controllers, battery inverters, communication software and hardware, safety devices, and more.


Sirius storage enables you to eliminate chemical storage from your portfolio and achieve significantly higher performance (efficiency, capacity, life), economically.

Centauri energy server enables you to eliminate every single hardware and software component in a microgrid (PV inverter, coupling, battery inverter, charge controller, microgrid controller, safeties etc.) and achieve significantly higher performance (efficiency, time-to-deployment, life).

Combined with PV solar (and any number of DC or AC generation sources), the Sirius / Centauri combination will allow you to lower cost, improve performance, and deliver reliable and stable electricity, over the long term.

Our system is very simple to deploy, with minimal data requirements, and the ability to eliminate the DG(Diesel generator) completely.

I will be happy to schedule a conference call, at your convenience, if you are interested in exploring further.

Key benefits of Centauri

Handles torque loads

Start motors, compressors and other forms of inductive loads with surge currents without oversizing the system.

Renewable input

Centauri directly supplies the load from renewable generation without routing through the energy storage during generation hours, whilst concurrently charging the storage. The platform switches seamlessly between renewable generation and storage and can accept 5 to 6 times the renewable input without oversizing the system.

Automated operation

The Centauri Energy Server actively corrects power factor losses caused by inductive and capacitive loads on the circuit and also filters any harmonics caused by the load. The platform includes built-in safeties, data logging, monitoring, and other control features.

Modular and scalable

GreenFox can help to assess requirements and recommend the appropriate Centauri configuration.
