4 FAQs about Resistors used in solar inverters

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.

What are the different types of resistors?

These requirements may include filter resistors, snubbers, gate resistors, bleeders, balancing resistors, voltage dividers, braking/regenerative braking resistors, power factor control, surge current protection, pre-charge resistors, and even current shunts. Here we will discuss the various resistor solutions.

What are the different types of solar inverters?

Solar inverters available today are generally divided into three types: central inverters, string inverters and micro-inverters. Central inverters are mainly used in large-scale ground power stations, suitable for high-voltage grid connections. The power range is normally between 100kW and 2500kW.
