HEXING coordinates power conversion, operating modes, plant communication, and outdoor setup. This helps customers get ready for commissioning with fewer disconnected systems.
A storage plant doesn’t swap electrical power. Instead, it shares commands, status info, alarms, and operating data. This goes to the control, monitoring, or energy management system.
When power equipment and communication tasks are planned apart, key details can be unclear. This can lead to confusion. These issues might not be resolved until commissioning. Interface definitions and protocol choice affect plant performance. Signal mapping, operating modes, and site conditions also play a role. Each factor is important for how well the plant works.
The Customer Problem: Late Integration Issues Create Site Pressure
A PCS might be ready, a transformer could meet specification, and MV switchgear may be installed correctly. But cannot operate as one coordinated plant until power, control, and communication interfaces are aligned.
Late questions from customers about commands, alarms, and operating data may need more answers. This is true for both grid-connected and off-grid systems. Sometimes, this means extra testing or site work. The main risk is not one individual component; it is the gap between several systems that must operate together.
How HEXING’s MV Power Conversion Unit Solves It: Plan Power, Control, and Communication Together
HEXING’s MV Power Conversion Unit combines several key components. It includes the bidirectional PCS, a step-up transformer, MV switchgear, and communication and auxiliary power functions. All these elements work together in one coordinated solution. The system supports both grid-connected and off-grid uses, depending on the final project setup.
Ethernet, RS485, and CAN interfaces, plus IEC 61850, Modbus RTU, and Modbus TCP options, form a solid base. They connect with plant-level monitoring, control, and energy management systems. The final communication architecture and signal requirements are confirmed during project design.

What Work and Risk Can Be Reduced
| • Earlier coordination of power, control, communication, and operating mode requirements. • Fewer disconnected systems to align during site commissioning. • A clearer path for status, command, alarm, and operating data exchange. • Better preparation for outdoor and non-standard site conditions. |
Outdoor configurations are designed for operating temperatures from -35°C to +60°C, with derating above 45°C. The PCS section is rated IP65, while other sections are rated IP54. These parameters help project teams check the basic environmental fit early. Final non-standard requirements still need project confirmation.
How This Helps During Commissioning and Operation
Planning the electrical and communication setup together helps commissioning teams. It clarifies responsibilities. It tests interfaces more effectively. It also stops treating each equipment package as a separate system. The same setup sends plant commands. It shares equipment status, alarms, and operating data during operation.
The customer benefit is a simpler integration process. It’s not just about having a longer list of protocols. The aim is to make the complete battery-to-grid system easier to prepare, connect, test, and operate.
What Projects Is This Approach Suitable For?
This approach is suitable for projects that require plant-level monitoring or energy management integration, grid-connected or off-grid operation, and outdoor deployment. Typical applications include utility-scale BESS, standalone energy storage plants, renewable energy and storage projects, user-side storage, and microgrids.
Questions to Align Before Commissioning
| PROJECT DISCUSSION CHECKLIST • Required operating modes and battery power flow control strategy. • Communication interfaces, protocols, commands, status, alarms, and data points. • Responsibilities for plant control, EMS, protection, and commissioning tests. • Outdoor temperature, enclosure, cooling, and non-standard site requirements. |
