In the Middle East, frequent power outages, high diesel generator costs, and the continuously growing electricity load are forcing commercial users to reconsider their energy choices. Recently, CHISAGE ESS successfully deployed a 120kW/120kWh high-voltage energy storage system in Diyala Province, Iraq. This system helped a local ceramic products store achieve a comprehensive upgrade from “diesel dependence” to “solar energy storage,” opening up a more stable, economical, and sustainable energy path for the user.
The client operates a ceramic products store in Diyala Province, Iraq, and has long relied on the utility grid and diesel generators for power supply. As a result, fuel expenses have remained consistently high. With an average fuel consumption of approximately 13 liters per hour, the generator alone incurs an annual fuel cost of around USD 15,000–20,000. In addition, routine maintenance conducted every three months, along with occasional breakdown repairs, further increases the hidden operational costs.
With the expansion of the business, new buildings are about to be put into operation, and the overall electricity demand continues to increase. At present, the load per phase is close to 100A, and once the new buildings are commissioned, the total load is expected to exceed 250A. Under the traditional power supply model, the system is no longer able to meet future development requirements in terms of stability, scalability, and safety redundancy. The client hopes to leverage a solar energy system to achieve a lower-cost, safer, and more reliable power supply structure. Under the combined realistic background of an unstable grid, growing loads, and sharply increasing costs, a systematic energy upgrade has become an inevitable choice.

In response to the client’s core requirements, this project adopts 108kW of solar panels, two Merc series 60kW high-voltage three-phase hybrid inverters (Merc-60G1-HE), and two sets of CAL series 60kWh high-voltage batteries (CAL60-RH).
After the commissioning of this 120kW / 120kWh system, solar energy is prioritized during the daytime to supply the loads while simultaneously charging the batteries, with the utility grid serving as a supplementary power source under intelligent system dispatch. As evening approaches and the overall load drops to approximately 10% of the daytime level, the system switches to a combined operating mode of battery discharge + grid support. Without any reliance on diesel generators, the system is still able to stably ensure the continuous operation of essential equipment such as lighting and surveillance. At the same time, the entire solution features flexible scalability and compatibility. As future load demand increases, the system can be upgraded by expanding the energy storage capacity to achieve smooth system expansion.
Transitioning from high-cost diesel dependence to a clean energy solution centered on solar and storage, this project is expected to achieve investment payback within three years, and thereafter continue to save the client approximately USD 20,000 in annual operating costs. This not only brings tangible cost optimization and power supply security to the store’s operations, but also once again demonstrates the real-world value of CHISAGE ESS high-voltage energy storage solutions in commercial applications across the Middle East. Looking ahead, CHISAGE ESS will continue to rely on stable and reliable product performance to help enterprises build a long-term, controllable, and low-volatility energy management pathway in complex power environments.
