For EPCs working on overseas energy storage and microgrid projects, selecting a PCS is only one part of the engineering process. Beyond the specifications listed in a datasheet, projects must account for local grid conditions, multiple power sources, environmental challenges, and on-site commissioning. A suitable energy storage inverter factory should therefore be considered not only from the perspective of equipment parameters, but also in terms of the engineering support behind the complete system.
In overseas bidding for energy storage and microgrid projects, competing on specifications and offering the lowest price are often only the first steps. When a project enters rigorous technical evaluation and implementation, EPCs and project developers face much more practical engineering questions:
- Can the equipment adapt perfectly to the local, potentially weak grid?
- When PV, energy storage, and diesel generators operate in parallel, could circulating-current oscillation cause system instability?
- What is the actual derating curve under high-altitude or high-salt-spray conditions?
- If an unexpected fault occurs on site, can a supplier thousands of kilometers away provide troubleshooting support at the underlying code level?
If an EPC focuses only on purchasing an inexpensive PCS cabinet, the project may face prolonged commissioning challenges during delivery. In complex PV-storage-diesel microgrid applications, the PCS is only the execution component of the overall system. It must work closely and reliably with MPPT systems, energy storage batteries, STS transfer switches, diesel generators, and the site’s complex load conditions.
YUNT’s Solution: Full-Stack Engineering Support Built from Global Project Experience
YUNT’s product capabilities are not limited to theoretical data developed in a laboratory. They are built on practical experience from projects across multiple regions and under challenging operating conditions.
From agricultural backup power in South Africa and diesel replacement in Nigeria to island microgrids in Madagascar, environmental-friendly diesel-storage coordination on construction sites in Singapore, and reverse power control for PV consumption in Bulgaria, each application has its own challenges. We have incorporated the solutions to these challenges into our power conversion control algorithms and hardware architecture.
For EPCs, we provide far more than hardware delivery. We provide an engineering-level support system covering the key stages of project implementation:
| Stage | Engineering Support |
| Early-stage risk assessment | Work with EPCs to evaluate microgrid integration schemes and provide accurate system topology references (SLDs). |
| Seamless integration | Provide detailed protection-setting recommendations, underlying communication point lists, and interlocking logic sequences. |
| Project commissioning | Experienced power electronics engineers provide remote or on-site commissioning support at the underlying system level to address complex issues such as diesel-storage oscillation and instability during islanded operation. |
Modular Microgrid Electrical Core
We have developed a highly standardized electrical core ecosystem covering Mars series grid-forming PCS from 30kW to MW level, fast-coordinating STS/ATS control cabinets, and high-frequency, high-efficiency SiC silicon carbide MPPT modules.
For different microgrid configurations, modular PCS module solutions provide the underlying power conversion foundation. The most complex AC-DC coupling and sequential switching logic in a microgrid is packaged into a safe and reliable hardware foundation.
As a microgrid electrical hub solution provider, YUNT Power’s practical projects have expanded across the world. Our equipment and solutions have successfully served projects in Europe (the UK, Germany, Spain, Italy, the Netherlands, Belgium, Switzerland, Austria, the Czech Republic, Slovenia, Romania, Bulgaria, Moldova, Ukraine, Poland, Lithuania, Latvia, Estonia, Finland, Sweden, Denmark, Hungary, and Cyprus), Africa (South Africa, Nigeria, Zambia, Zimbabwe, Madagascar, and Cameroon), the Middle East and Asia-Pacific (Yemen, Jordan, Palau, India, Myanmar, South Korea, Thailand, Vietnam, Malaysia, Singapore, and the Philippines), and South America (Brazil), covering dozens of countries.
We provide a complete engineering foundation that includes modular PCS hardware, EMS dispatch logic, load-splitting solutions, and system electrical topology. Customers can leverage their own local delivery capabilities and resources while entrusting the underlying power conversion and control challenges to us, enabling the delivery of resilient energy systems that balance economics and high reliability.
When an overseas microgrid project requires coordination across equipment, control logic, and on-site engineering, YUNT can be part of the engineering support behind the system.
