Choosing An Inverter For Solar Panels

What is an inverter.

Choosing an inverter for solar panels. Solar inverter has a terminal for connecting battery and solar panels of correct rating. How to choose the right solar inverter size for your solar power system. A solar inverter functions to convert the direct current dc generated by solar panels into the alternating current ac which is used by families. Solar inverters come in all different sizes big and small.

A string or several strings of solar panels is connected to one inverter. Average power would usually be much less than typical or surge and is not usually a factor in choosing an inverter. If you run a pump for 20 minutes and a small tv for 20 minutes during a one hour period the average might be only 300 watts even though the pump requires 2000. The solar inverter is what turns the solar energy generated by solar panels into the useable electricity that powers households.

The energy generated by the solar panels is in the form of direct current dc energy. This has been a common solar pv system design for decades and works well for most homes. 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 difference of solar inverter from normal inverter is that the solar inverter consists of solar charge controller and some switching circuits.

Similar to solar panels the size of an inverter can be rated in watts w. Size of your solar array. While some solar panels and installations come with their inbuilt inverters such as the tesla powerwall 2 they still require an external solar inverter to function as a solar array fully. 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.

Also one of solar power world s top 100 solar contractors will share case studies that demonstrate considerations such as safety operations maintenance and grid connection for choosing the right inverter for your utility solar installation. Dc electricity only flows in one direction and is the type of electricity used to power phones and laptops. When it comes to solar inverter sizing installers will take three primary factors into account. Solar inverters convert the low voltage dc electricity created by your solar panels to the 120 volts ac electricity used by household appliances.

The inverter is mounted on an external wall typically near the home s switchboard. There s a chance of the solar panels under delivering on power. Solar inverters are instrumental when it comes to solar energy harvesting and increasing the efficiency of the system. The size of your solar array your geography and site specific conditions.

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.
