Technical FAQs 4

How do film capacitors work in solar inverters?

Film capacitors for use as the energy buffer in solar inverters consist of a winding of two layers of metalized polypropylene. The thickness of the polypropylene determines the voltage rating, which can go up to several kV. The metallization on the propylene is contacted by spraying metal droplets on the side of the winding.

Do solar inverters need inductors?

Solar inverters need inductors that are capable of handling high voltages and large currents in the main circuit. Panasonic inductors, thanks to their high-quality design, can meet these requirements ensuring a stable inductance value during lifetime.

What makes a good solar inverter resistor?

For the resistor, this means high reliability with long lifetime, high voltage-withstand capability and high accuracy. Panasonic has a variety of resistor families that can be employed in solar inverters applications.

What is a solar inverter?

A solar inverter (also called a photovoltaic or PV inverter) converts direct current (DC) into alternating current (AC) and is widely used in solar photovoltaic power generation systems. Solar inverters available today are generally divided into three types: central inverters, string inverters and micro-inverters.
