1. What is a Box-Type Substation PV Inverter Boosting Device?
A Box-Type Substation PV Inverter Boosting Device, also known as a photovoltaic (PV) step-up box-type substation, is an integrated power conversion system designed for solar energy applications. It combines a transformer, high/low-voltage switchgear, control systems, and protection mechanisms within a compact, transportable steel enclosure . Its primary function is to convert the low-voltage direct current (DC) generated by PV panels into higher-voltage alternating current (AC) for efficient grid integration. This system is characterized by its modular design, weatherproof structure, and adaptability to diverse environmental conditions .
