Microgrid

Kilowatt Labs’ Microgrid solutions deliver electricity connectivity with unprecedented performance at the lowest cost in the world.

Kilowatt Labs’ Microgrids are based on the patented Centauri Energy Server and Sirius Energy Storage modules, combined with renewable and non-renewable generation sources.

The Centauri Energy Server delivers power control system functionality to operate a microgrid. It eliminates the need to procure, install, and sync multiple elements like PV inverters, MPPTs, battery inverters, SCADA, microgrid controllers, communication and logging software, safeties, etc.

Combined with Sirius Energy Storage, Kilowatt Labs’ Microgrid solutions deliver reliable, stable, consistent, and maintenance-free electricity affordably, which can be deployed in any size from kW to MW, supply any kind of load from a house to a city, and can be installed in any application.

Key Features

Singular, plug-and-play platform	Plug-and-play connectivity for concurrent, multiple, DC or AC generation inputs	Plug-and-play connectivity for storage	AC Output - Handles torque loads and inrush currents up to 1000% for 2s	Standard Features
Eliminates the need to buy PV inverters, MPPTs, battery inverters, SCADA, microgrid controllers, communication and logging software, safeties	PV, DG, grid, etc. No upper limit to renewable input connectivity Seamless switching between input sources (0.00ms) – does not destabilize the load Energy blending or sequential usage of input sources	Does not require additional battery inverter Handles renewable intermittency by switching seamlessly between renewable generation and storage Concurrently charges storage during PV generation hours	No oversizing necessary to start motors, compressors - loads with surge currents Actively corrects power factor losses caused by the load to 1 Filters harmonics caused by the load 50/60Hz settable	Data logging, monitoring, and control Bypass – auto, static, manual Safeties Auto genset start/stop Modular and scalable – power capacity can be increased by adding servers in parallel

Benefits

Centauri is a singular and integrated software and hardware platform that does not require any additional hardware, software, protection, switching, or monitoring solutions.
Because the Centauri has been designed as one unit, it is optimized to deliver high efficiency, resilience, and error-free operation.
Centauri and Sirius are modular, so capacities can be increased with growing demand.
PV plants are optimized due to the high roundtrip efficiency of the Sirius Storage, coupled with Centauri’s efficiency levels.
Centauri corrects power factor losses generated by the load and filters harmonics, allowing optimization of energy input sources.
Centauri can deliver sequential or blended power from input sources (AC or DC).
The system has a design life of 20 years.
No replacement or disposal costs.
No environmental impact.

Case Study

The implementation of an off-grid solution using the Sirius Supercap Energy Storage and Centauri Energy Server has enabled an incredible increase in production levels by micro and small enterprises in the town of Dukana, located in Marsabit, Kenya – hospitals are able to attend to more patients, schools can now operate for longer hours, and overall, the maintenance costs of these institutions were brought down to a minimum.

Residents have also found newer sources of income by opening up refrigeration and welding services, hair salons, and phone charging stations, none of which would have been successful without the assurance of uninterrupted power supply provided by Centauri Energy Server and Sirius Energy Storage.
