When designing energy storage systems, we often ask clients about the proportion of inductive loads in their system and use this information, combined with other basic system parameters, to determine the system configuration. So, what are inductive loads? In simple terms, they are motor-based loads. In industrial settings, these include loads like water pumps and hydraulic systems, while in commercial settings, they typically involve air conditioners, elevators, and similar equipment. A key characteristic of these loads is that during startup, the inrush current can reach 3–7 times the rated current, causing a significant spike in the system's instantaneous load demand. Even with soft-start devices like variable frequency drives, the startup current can still be 2–3 times the rated current.

Isla Grande in Colombia, a vibrant Caribbean island home to approximately 1000 Afro-Colombian descendants, has long sought a reliable and sustainable energy solution. This case study highlights the successful implementation of a cutting-edge hybrid solar-diesel power plant on Isla Grande, significantly improving the quality of life for its residents and fostering sustainable development. ATESS, a leading provider of advanced energy storage solutions, played a crucial role in this transformative project, deploying its PCS250 battery inverters,and battery storage system to enable an efficient and robust AC-coupled off-grid system. This innovative solution, seamlessly integrating with existing grid-tied inverters and diesel generators, ensures 24-hour electricity service for the first time, reduces reliance on fossil fuels, and lays the groundwork for future grid integration.

In this era of increasingly decentralized and cost-sensitive energy demands, off-grid microgrid systems have become the go-to solution for remote areas, islands, mining sites, emergency scenarios, and even urban backup power. However, challenges such as high initial investment, complex maintenance, and poor environmental adaptability remain industry pain points. Leveraging advanced technology integration, LCOE optimization, and a global service network, the ATESS SMC200 smart MPPT controller redefines the standard for off-grid solar energy storage system — empowering users to achieve uncompromised energy independence.

Iraq faces a severe and persistent electricity crisis. Frequent blackouts, soaring temperatures, and an over-reliance on expensive, polluting diesel generators cripple businesses and disrupt daily life. In 2025, Iraq will require approximately 54 GW of electricity to achieve power balance, while the current generation capacity stands at only 15 GW—indicating a substantial shortfall. During peak summer demand, this shortage becomes more severe, with many regions relying on small diesel generators to supplement the grid. This case study highlights how ATESS hybrid solar systems are providing a robust, sustainable, and cost-effective solution to these challenges. Through two typical cases in Slemani, we demonstrate how ATESS is helping Iraq to achieve energy independence, reduce operational expenses by up to 90%, and significantly lower their carbon footprint, paving the way for a more resilient and sustainable energy future in Iraq.
