Industrial and Commercial Weak Current Network System Solutions

The weak grid system is tailored for low-voltage grid scenarios, dedicated to providing users with solutions for continuous power supply under unstable grid conditions.


The system employs an innovative transformerless three-phase four-wire (3P4W) architecture, facilitating transportation and expansion in weak grid environments; It addresses the challenge of 100% unbalanced three-phase loads whilst delivering exceptional overload capacity. External current and voltage sampling interfaces enable real-time, precise monitoring of load conditions. Flexible AC/DC-side coupling further enhances customer choice.


Leveraging multiple technological advantages, the system adapts to diverse weak grid applications, comprehensively meeting users' personalised, high-reliability power requirements.
