Built around the confirmed duty
The 2026 manual describes the photovoltaic transformer substation as a stable power-conversion and transmission package for PV generation. It converts the system output through the inverter interface, transforms it to the required grid voltage and connects through a dedicated AC circuit breaker, with monitoring and protection functions integrated into the package.
Working principle
Inverter AC output enters the box substation, is switched and transformed to the collection or grid voltage, monitored and protected, then exported through the outgoing circuit.
New-energy equipment selection requires the rated electrical or process duty, operating profile, grid or process interface, site climate, thermal management, communication and destination certification.
Core features
- Integrated photovoltaic step-up and grid connection
- Real-time operating monitoring described in the manual
- Overvoltage, overcurrent and islanding protection functions
