Off-Grid Solar Powered Site, UAE.
48 Hour Backup
Project 1
142 kWh at 48V.
Configuration: 142 kWh ENCAP storage, 88 kW hybrid inverter, and 110 kW solar.
Project 2
142 kWh at 48V
Configuration: 142 kWh ENCAP storage, 80 kW hybrid inverter, and 89 kW solar.
Project 3
128 kWh at 48 V.
Configuration: 128 kWh ENCAP storage, 100 kW hybrid inverter, and 110 kW solar.
Applications
Designed to provide 48 hours of backup for critical loads in remote area sites where fuel refilling and site access are challenging. During the day, solar energy charges the storage system while powering the load, and at night, the stored energy ensures uninterrupted operation with remarkably fast response time.
Power & Energy
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 6 kW DC load, the system integrated a robust infrastructure comprising a 15 kWp solar PV array, complemented by a 60 kVA diesel generator (DG) for backup power.
The heart of the system lies in the deployment of 12 cutting-edge 3.55 kWh, 48 V DC modules, totaling 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.
