Technical FAQs 4

What is a PVB backflow preventer?

The PVB backflow preventer 1-720A is used in high hazard applications and is primarily used in non-potable residential and commercial irrigation systems. It includes an approved check valve, vacuum relief, and two test cocks.

Why is anti-backflow protection important?

Grid regulations typically restrict unpermitted backflow, and unauthorized power feeding can result in penalties. For PV projects designed for self-consumption without grid feeding, anti-backflow protection is crucial for achieving sustainable energy independence. What Is Anti-Backflow?

What are anti-backflow solutions?

Summary Anti-backflow solutions address the "grid-connected but non-feed-in" policy requirements of specific regions. They enhance grid stability, improve system safety, optimize energy efficiency, and adapt to evolving technologies and policies.

What is a blocking diode in a solar photovoltaic array?

Blocking diodes are basically used in solar photovoltaic arrays when there are two or more parallel branches, or there is a possibility that some of the array will become partially shaded during the day as the sun moves across the sky. The size and type of blocking diode used depend upon the type of solar photovoltaic array.
