How To Select Inverter For Solar Panel

String inverters a single inverter for all your solar panels that takes the dc power supply from the sun and converts it into ac power for the home.

How to select inverter for solar panel.

If you install the same sized array with a 5000 inverter the ratio is 1 2. This guide will help you evaluate the different solar panels and inverters available so that you can choose the best equipment for your home. A solar inverter functions to convert the direct current dc generated by solar panels into the alternating current ac which is used by families. From this perspective choosing the best solar inverter for you is extremely important if you are planning to go solar or buy it for your solar power.

The array to inverter ratio of a solar panel system is the dc rating of your solar array divided by the maximum ac output of your inverter. Solar inverters convert the low voltage dc electricity created by your solar panels to the 120 volts ac electricity used by household appliances. Microinverters multiple small inverters that sit underneath or next to each individual panel. There are two main components to a grid connected solar energy system.

The solar panels themselves which create electricity from sunlight and the inverter which converts the electricity into a form you. The latter allows us to save cost by not purchasing another inverter and like we saw in figure 1 we can still harvest more energy during off peak hours. For example if your array is 6 kw with a 6000 w inverter the array to inverter ratio is 1. If we want a larger system size we could place another 100 kw block a section of solar panels connected to an inverter or we can pack more dc power generation onto our first inverter.
