These past years, many have invested in a home solar energy system because it helps the environment and cuts down on bills. After all, it uses free sunlight to produce clean electricity. But, if you're interested in getting one, you have to be careful. Choosing the right panels isn't the only thing you should think about. Having great Fronius solar inverters is also crucial since their main components convert direct currents into usable alternating currents.

That said, a solar inverter isn't a one-size-fits-all device. It has a lot of models with different specifications made for varying applications. This can be overwhelming, especially if you don't know what to look for. To make things easier, here are some essential factors you need to check before buying a unit.

Type

First, you have to understand what kind of inverter you need. Here are some of the most common options people use for their homes:

  • String inverters - These are standard models that'll work well even if they don't get any shade to keep them cool. They have one central currency exchange, which means all currents coming from the panels go through a single outlet.
  • Micro-inverters - These units are small devices built under each individual solar panel. This gives each piece the ability to function at its peak capacity since the energy is converted immediately. This characteristic also lets you monitor the performance of each panel, which is incredibly helpful in identifying and troubleshooting issues.
  • Power optimizers - Essentially, these are somewhere between a string and micro-inverter. Power optimizers are also attached under each solar panel. But, instead of changing DC to AC right away, these devices optimize the current before sending it to the central inverter.

Operating Temperatures

Like most devices, inverters work best when they're not overheating. So, determine the unit's optimal operating temperature so you know what levels the equipment should be running on.

Inverters will normally produce heat as they operate. Also, since they're outside the house, they're exposed to fluctuating temperatures. This isn't ideal since it'll force your unit to work harder. But, by ensuring it has a high operating temperature, you'll have confidence it can handle the load.

Unit Efficiency

Even though solar panels are meant to harness and produce energy, you won't be able to use all of it as some just gets lost during the conversion from DC to AC. This means you should have an efficient inverter so you can fully take advantage of the benefits the system offers.

Generally, there are two numbers to look for when checking this factor: peak efficiency and weighted efficiency. The first one will give you a look at how the unit will run at its best. It's crucial to note that it won't always hit this level because other factors like temperature may affect how it runs.

This is where the unit's weighted efficiency comes in handy. It gives a more accurate gauge as it also considers the temperature and other environmental elements that can affect how the inverter works throughout the day.

Having a rooftop solar energy system is great for both the environment and your budget. So, when looking for components, do your research to get an idea of what you should buy. This ensures that you gain the most out of your investment. Contact the PowerStore Inc. to learn more about a Fronius hybrid inverter.
