Inverter Functionality

Like a traditional inverter, the PCU converts the DC current generated by solar panels into AC, which is the form of electricity required by most commercial and industrial equipment and appliances.

Grid Management

A PCU can manage the distribution of power between the solar panels, battery storage (if present), and the electric grid. It ensures that the power generated is used efficiently, either by:
● Supplying it directly to the building's energy load.● Storing excess power in batteries (if part of the system).● Exporting surplus electricity back to the grid if grid-tied and allowed by regulations.

Power Regulation and Conditioning

The PCU ensures that the power being supplied to the building’s electrical system is of the right voltage and frequency. This conditioning process ensures the stability and reliability of power to protect sensitive equipment from surges, sags, or fluctuations in electricity.

Hybrid System Management (in some systems)

PCUs in hybrid solar systems can manage power from both the solar panels and backup sources like diesel generators or battery banks, intelligently switching between power sources to maintain an uninterrupted supply.

Monitoring and Protection

The PCU typically comes with monitoring capabilities, allowing real-time tracking of system performance, including power generation, consumption, and the health of various system components. It also protects the system from issues like over-voltage, overcurrent, or short circuits.
