Why do PV farms need inverters?

PV farms are comprised of very sensitive equipment that needs expansive protection. Because PV farms create direct current (dc) power, inverters (which are necessary to convert this power from dc to ac) are an essential component to their electrical production.

What is PV protect?

PV Protect is the compact solution for optimal protection of the inverter against overvoltages The ready-to-connect boxes are available for different system voltages and can be supplied with various arrester types and MPP trackers.

Do PV systems need electrical protection?

As the installations and demand for PV systems increases, so does the need for effective electrical protection. PV systems, as with all electrical power systems, must have appropriate overcurrent protection for equipment and conductors.

Do PV current sources need a disconnector?

Therefore, PV current sources not only require larger PV switches and PV fuses, but also a disconnector for the surge protective device which is adapted to this unique nature and capable of coping with PV currents . SPDs installed on the dc side must always be specifically designed for dc applications.

How to protect photovoltaic strings from reverse currents?

String protection against reverse currents Miniature circuit-breakers Use of thermo-magnetic circuit-breakers is a further method for protecting photovoltaic strings. Thus, manufacturers have created specific products comprising technological solutions able to function at high the direct current voltage values that are usual in these applications.

Why are PV inverters so dangerous?

Since PV inverters are looking for a voltage source and the voltage is present, the load will absorb current from the inverters, creating voltage across it, perpetuating a situation where, in theory, everything will run forever, making a safety and reliability concern across the grid.
