AT&T Off-Grid Solar Site, California - USA
Spearheaded a groundbreaking project in collaboration with AT&T, focusing on enhancing the efficiency and sustainability of off-grid sites in California, USA. The project involved the development of a sophisticated Hybrid Application system tailored to meet the specific demands of the site.
With a 6KWDC Load, the system integrated a robust infrastructure comprising a 15kWp Solar PV array, complemented by a 60kVA Diesel Generator (DG) for backup power. The heart of the system lay in the deployment of 12 cutting-edge 3.55kWh, 48VDC modules, totalling an impressive 42.6kWh storage capacity.
One of the primary objectives of the project was to significantly reduce DG runtime, thereby minimizing operational costs and environmental impact. Through meticulous design and optimisation, Emtel Group achieved a remarkable reduction in DG runtime, slashing it from 6 hours to a mere 50 minutes. This achievement not only represented a substantial improvement in efficiency but also translated into tangible Opex savings for AT&T.
The Hybrid Application developed by Emtel Group stands as a testament to innovation and sustainability in the field of off-grid power solutions. By harnessing the power of renewable energy sources and advanced storage technologies, the project exemplifies a paradigm shift towards greener, more efficient energy systems, setting a new standard for off-grid site operations.

Containerized Solution
- In 2020 we supplied a Containerized Microgrid Solution for a off-grid Solar PV powered cabin in Popular National park in USA.
- The Microgrid consisted of a 20ft container with 208 kWh of Sirius Energy Storage and 20kW Energy Server with PV Input.
- In 2022 due to flooding incident , all other microgrid solutions with other technologies in the Park either failed or turned off…. other than the Sirius Supercap Containerized System
