As the "dual carbon" goals are deeply advanced, the integrated application of PV power generation and energy storage systems (PV-storage integration) has become a core direction of the new energy industry. However, a large number of PV energy storage projects face practical difficulties during implementation, including chaotic device protocols, difficult dispatch control, high O&M costs, and low intelligence levels. There is an urgent need for a full-stack edge solution from field control to station-level intelligence.
PUSR has been deeply engaged in the PV new energy field for many years. Addressing typical industry pain points, PUSR provides a complete solution path from device access and field control to station-level AI through the collaborative deployment of three products: the industrial computer EG828 (EMS), EG628, and EG1000.
Different brands of BMS, PCS, inverters, and meters each use their own protocols. System integrators need to spend a great deal of effort on customized adaptation, leading to frequent project delays and rework.
PUSR Solution:
The industrial computer EG828 (EMS) natively supports 10+ industry protocols including Modbus RTU/TCP, IEC61850, IEC104, DLT645, and CAN. A single device uniformly accesses all field devices without additional protocol converters, reducing integration workload by over 70%. The EG628 also supports Modbus, OPC UA, IEC104, IEC61850, and other protocols for acquisition and conversion, meeting the demand for multi-device parallel access in complex scenarios.
Energy management algorithms such as peak shaving and valley filling, anti-reverse power, and demand control require professional team development. Project delivery cycles are long, and the coupling between algorithm platforms and hardware is high, making reuse difficult.
PUSR Solution:
The industrial computer EG828 (EMS) is based on an open Linux system with fully integrated interface drivers. It comes with the built-in WukongEdge edge computing platform, supporting Node-RED low-code programming and C/C++ secondary development. Engineers can complete peak shaving, valley filling, and anti-reverse power strategy deployment within days, significantly shortening project delivery cycles. The EG628 also comes with WukongEdge and supports OpenPLC programming compliant with the IEC61131-3 standard, with five PLC languages available. Engineers accustomed to traditional PLC programming can get started with zero learning curve.
When the energy storage system has an anomaly, O&M personnel cannot quickly locate the problem on-site and can only rely on remote platforms or traveling to the site, resulting in low response efficiency and high maintenance costs.
PUSR Solution:
Both the industrial computer EG628 and EG1000 come with built-in local configuration functions. Configuration is completed in three steps. The on-site HMI screen displays key indicators such as battery SOC, PCS output, and alarm status in real time, enabling local diagnosis without internet. The EG1000 comes with its own display screen, allowing full-station operation status to be viewed right at the cabinet door, completely changing the "blind O&M" predicament.
Commercial and industrial energy storage sites are scattered. Every parameter adjustment and firmware upgrade requires sending personnel to the site. Labor and travel costs remain high, and the problem becomes more prominent as the scale grows.
PUSR Solution:
All three products support unified management via the PUSR Cloud platform. Combined with OpenVPN/IPSec remote networking, they enable multi-site remote parameter configuration, policy distribution, and OTA firmware upgrades. One person can manage dozens of sites. The EG1000 caches data locally when disconnected and automatically uploads upon recovery, ensuring no data loss and completely solving the "isolated site" problem.
Different energy storage projects vary greatly in scale. Standard gateway IO counts are either redundant or insufficient. Adding expansion modules brings extra cost and installation complexity.
PUSR Solution:
The industrial computer EG628 adopts a modular expandable architecture with high-speed IO expansion interfaces. DI/DO/AI modules can be added on demand. One host adapts to projects ranging from small commercial and industrial storage of hundreds of kWh to large MWh-class energy storage stations, avoiding repeated selection and procurement for different projects. The EG828 (EMS) comes standard with 16-channel isolated DI, 6-channel relay DO, and 4-channel ADC, meeting the wiring needs of the vast majority of energy storage cabinets.
The demand for AI video inspection, fault prediction, and PV output prediction in PV power stations is growing stronger. However, traditional gateways generally have less than 1T computing power and cannot run practical-grade AI models.
PUSR Solution:
The industrial computer EG1000 rack-mounted AI industrial computer comes standard with a 6T NPU. Through 2 PCIe M.2 slots, it can be expanded up to 46T computing power. It supports mainstream AI frameworks including TensorFlow, PyTorch, and ONNX, and can simultaneously run 32-channel 1080P video analysis algorithms, enabling AI applications such as smoke and fire detection, personnel intrusion detection, equipment anomaly recognition, and battery aging prediction — pushing PV energy storage stations into a new phase of intelligent O&M.
Some energy storage sites have complex site conditions. Existing gateways only support a single power supply mode. In AC/DC hybrid power supply environments, additional power modules are required, increasing cost and failure points.
PUSR Solution:
The industrial computer EG1000 supports DC 12~48V wide-voltage and AC 100~250V dual-mode power supply, flexibly adapting to both AC mains and DC energy storage busbar power supply scenarios, reducing peripheral power distribution costs. The EG828 (EMS) supports 12~48V wide-voltage DC power supply and provides 2-channel isolated 12V regulated output, capable of directly powering on-site sensors, 4G routers, and other auxiliary equipment.
The EG828-EMS is a high-performance multi-interface energy storage microgrid controller designed by PUSR specifically for new energy storage systems. It comprehensively considers the needs of different scenarios including energy storage power stations, microgrid storage, commercial and industrial storage, and PV-storage charging stations. It provides all-around interface resources and is the preferred core device for the field control layer of PV-storage projects.
