What is a Solar AC Distribution Board (ACDB)?
Safe & Reliable AC Power Distribution for Solar Power Plants
A Solar AC Distribution Board (ACDB) is a vital electrical panel used in solar photovoltaic (SPV) systems to distribute AC power from the inverter to the load or LT panel. It combines three-phase and single-phase AC outputs of the inverter into a single, protected distribution point.
AAVAD Instrument Pvt. Ltd. manufactures CPRI-approved Solar ACDB panels designed for safety, durability, and compliance with Indian and international electrical standards.
Role of ACDB in a Solar Power Plant
The ACDB acts as the interface between the solar inverter and the electrical distribution system. It protects downstream circuits and ensures reliable AC power distribution while safeguarding both equipment and personnel.
Key functions include:
Distribution of inverter AC output
Protection against overload, short circuit, and surges
Electrical isolation for maintenance
Energy monitoring and metering
Types of ACDB Manufactured by AAVAD
