Schneider MVnex550 solution landing photovoltaic project, fault response reduced to 200ms

2025-11-04

Author:

The Schneider authorized cabinet MVnex550 intelligent solution has achieved breakthrough application in a distributed photovoltaic project in an industrial park in Shanghai, compressing the system fault response time from 15 minutes to 200ms and successfully avoiding equipment damage caused by islanding effects. The 3000 square meter rooftop photovoltaic project needs to meet green building certification, and MVnex550 has solved the problem of space limitations through triple technological innovation. ​
The photovoltaic energy storage collaborative control system relies on the Easergy P5 microcomputer protection device to dynamically adjust the energy storage charging and discharging strategy, ensuring that the voltage deviation at the grid connection point is ≤± 2%; The combination of PM8E smart meter and edge computing module controls the data transmission delay within 10ms; The IP66 protective cabinet is equipped with a temperature and humidity adaptive system, which maintains an insulation resistance of over 1000M Ω during the rainy season. The spontaneous self use rate of the final project increased to 78%, becoming a benchmark case for intelligent distribution in the field of new energy.
