Top Solar Inverters for your Home!
Solar inverters are one of the essential parts of a solar system installation. But it’s also one of the most delicate parts and is likely to have issues. That is why it’s essential to buy a quality inverter and install it in a sheltered place to make sure it will be able to resist and have a long lifespan.
Continue reading and access the list of the best solar inverters available in Australia, so you can be confident that you’ll choose the one that best suits your home and needs.
What is the function of a Solar Inverter?
First of all, here is a simple explanation of the function of the solar inverter within the solar system:
A Solar inverter is the part of the solar system responsible for transforming the energy produced in a solar system installation, which is transmitted through direct current (DC) into alternating current (AC).In this way, the electrical appliances and other electrical devices will function normally and without danger.
What to look for in a solar inverter?
It’s as critical to choose solar panels as it’s the inverter. When selecting the inverter for your solar installation, you must take into account the following characteristics:
- Maximum transformation power:
It’s the maximum amount of energy that the inverter will be able to transform, and it can be expressed in both (W) and (VA). Although the inverters all come with security measures, you must choose the model that best suits your electrical installation. If not, it is better to install separate shutdown and ignition systems, to avoid any electrical overload.
- Protection systems:
Solar inverters must be able to stop production in the event of a short circuit, grid, or component failure. If this is not possible, you must install a separate shutdown system.
- Optimization:
The inverter must optimize the solar production regardless of the shadows or the installed panel type. Therefore, you must choose which inverter is most appropriate for your home.
- Data register:
Getting a system that registers production data will allow you to monitor the production of the panels and find out if there are any problems you should be aware of.
As you may already know, choosing a suitable solar inverter is essential to make the most out of your solar system. Next, we will discuss the top brands of solar inverters in the market and when to choose each.
