Fronius System Monitoring Hardware and Software

Fronius System Monitoring Hardware and Software

Another standout feature that Fronius provides is an array of solar monitoring solutions – both in hardware and software form. These are designed to track a PV system’s performance, which in turn can help customers identify whether or not they’re getting the most value out of their solar system.

According to their website, Fronius states hardware is “quick to install and software is intuitive to use.” But do their monitoring capabilities actually provide some useful insights or are they just a ploy to get their solar products over the line? Let’s explore some of Fronius’ system monitoring tools in further detail below.

What is a Fronius Smart Meter?

The Fronius Smart Meter is a device that allows customers to record how much energy their solar system produces, as well as how much energy their household uses and exports back to the electricity grid. The smart meter can be wall mounted indoors or outdoors, and measures 140 x 38 x 85mm, and weighs 310 grams.

What is Fronius Solar.web?

Put simply, Fronius Solar Web is the software that makes transmits the data recorded from the smart meter. Customers can log into the Fronius Solar.web monitoring platform using the online portal or via the app, both of which have a number of functions that measure the overall performance of a solar system.

Cost of Fronius Systems

The cost of a Fronius system will depend on which product you choose for your household’s solar needs. As a general guide, the price of a Fronius Primo inverter ranges from $1,500 to $6,500.

A Fronius solar battery for residential use can cost anywhere between $10,000 and $20,000, depending on the model you are after. Again, this doesn’t take into account installation costs. With a price tag big enough to make your jaw drop, it’s important to do your own research and calculate how much you’ll be getting back in energy savings over a long period of time. To get an accurate quote for your home, it’s best to contact a certified Fronius installer near you.

Should I invest in a Fronius solar storage unit?

Whether it’s a battery, inverter or complete solar system, you’ll need to think about the heavy upfront costs which can easily set you back thousands of dollars. While a Fronius energy storage unit aren’t exactly cheap, you may find a return on your investment over the long term, provided you’ve done your homework.

Investing in solar can help you save on annual power bills because you’ll be less reliant on the electricity grid. The savings you may see over a timeframe will vary depending on how many panels your home has, the size or output of your system, as well as your household energy usage needs, to name only a few.

Before making such a big financial decision, make sure you assess which energy storage system is required to power your home. Given the range of solar products and technology offered by Fronius, you may be able to find a battery or inverter that isn’t available with other brands.

If you’re adamant about going solar, you’ll need to make sure your current electricity plan is up to scratch, otherwise you could be missing out on higher feed-in tariffs, as well as other sign-up incentives.
