The United Arab Emirates (UAE) is known for its rapid economic growth and urban development. However, in remote areas or locations with limited grid access, reliable electricity supply can still be a challenge. This case study focuses on the design, implementation, and benefits of a 10 kW off-grid inverter system coupled with a 20 kWh LiFePO4 battery storage solution in a remote region of the UAE.

Customer requirements:

• Sustainable Energy: Provide a sustainable and reliable electricity supply to the remote community while reducing dependence on fossil fuel-based power generation.
• Energy Security: Ensure stable energy supply, especially during peak consumption periods and potential grid outages.
• Environmental Sustainability: Reduce carbon emissions and minimize the environmental impact of energy consumption.
• Economic Viability: Establish a cost-effective solution that would save the community money over the long term.

The solution:

• Solar Photovoltaic Array: A solar array with a capacity of around 12 kWp was installed to capture ample sunlight in the desert region. This capacity was designed to meet the daily energy consumption needs of the community while allowing for surplus energy generation for battery charging.
• 10 kW Off-Grid Inverter: An off-grid inverter with a 10 kW capacity was chosen to convert the DC energy generated by the solar panels into AC power suitable for household and community use. The inverter was equipped with advanced monitoring features for real-time energy management.
• 20 kWh LiFePO4 Battery Storage System: A 20 kWh Lithium Iron Phosphate (LiFePO4) battery storage system was integrated to store excess solar energy during sunny periods. The LiFePO4 batteries were selected for their high efficiency, long cycle life, and reliability in high-temperature environments.
• Energy Management System (EMS): An intelligent EMS was deployed to monitor and manage energy flow, battery state of charge, and load demand. The EMS optimized energy distribution, prioritized critical loads, and ensured optimal battery charging and discharging cycles.
