Working Principle

In a photovoltaic power generation system, solar modules generate DC power, which is converted into AC power through the string inverter. The AC output enters the PV Grid-Connection Box, where the electrical protection devices monitor and protect the circuit before connecting to the transformer and utility grid.

PV Modules → String Inverter → PV Grid-Connection Box → Transformer → Utility Grid

The grid-connection box ensures:

• Safe power transmission
• Fault protection
• Equipment isolation
• Surge protection
