6 FAQs about [Can photovoltaic panels use limit blocks ]

What is a solar PV export limitation?

When in the planning and design stages of a solar PV project, you may come across the term export limitation. Essentially the process involves fitting a device to cap exported power going from the solar system to the grid. But why would you want or need one? Read on to find out What is export limitation?

What is a photovoltaic injection limitation?

The injection limitation consists of controlling the amount of electricity produced by a photovoltaic installation injected into the grid. Limiting active power injection may be necessary to relieve the grid and reduce the reinforcement costs that this would imply.

How can a DNO protect a large solar PV system?
