4 FAQs about [Solar inverter charging resistor]

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.

How to charge a DC inverter?

Pre-charging an inverter is simple. You just need to connect a suitable resistor between the DC load and inverter for a few seconds. Then, remove the resistor and connect the DC load to the inverter. The following method breaks this down, step by step. Connect the inverter to your negative and positive busbars.

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.

Do I need to pre-charge my inverter?

All of our large inverter and inverter/charger kits include the required resistor to allow you to safely pre-charge it. If you have a lithium battery bank, it's really important to pre-charge your inverter (2000W+) to protect your BMS. Nevertheless, pre-charging is still necessary if you have AGM batteries.
