Photovoltaic box type substation (PV box type substation) is the core equipment in photovoltaic power generation system, which is used to boost the low-voltage DC power generated by photovoltaic modules to the grid voltage (such as 10kV or 35kV), and realize the integrated device of power distribution, protection and intelligent monitoring.

Core functions:

Electricity conversion: The direct current (DC) output from photovoltaic modules is converted into alternating current (AC) through an inverter, and then stepped up to the grid level (such as 10kV) through a transformer. ‌‌

Distribution protection: Built in circuit breakers and overcurrent protection devices ensure stable connection to the power grid. ‌‌

Intelligent monitoring: supports remote real-time monitoring (such as temperature and humidity, voltage), achieving "four remote" (remote communication, telemetry, remote control, remote adjustment). ‌‌
