Fronius Primo 3.8kW Inverter FRO-P-3.8-1-208-240
Great service from A1 SolarStore. Unfortunately, the inverter was defective out of the box. Hardware error 407. Fronius tech support is very good. Awaiting the replacement.

Fronius Primo 3.8kW Inverter 3.8-1
The inverter itself is great, but it’s suitable only for very small installations. Well, a 5kW one actually is fine. Too bad it’s grid -tie, i wanted to use it for my van(

Fronius Primo 10kW Inverter FRO-P-10.0-1-208-240
I bought Fronius Primo 10kW for a system consisting of 27 modules 370W each. So far so good. A1 Solar had the lowest price, but their standards were up to the expectations. Can recommend both the inverter and the store

Fronius Symo 10 kw Inverter 10.0-3 208240L Advanced
I’ve seen a few inverters fail not long after the warranty’s end. For this model you can extend the warranty up to 20 years with a few clicks on the Fronius website, which is exactly what I’ve been looking for

Fronius Primo 12.5 kW Inverter
Great inverter, but software could be better. Spent many hours trying to set up the app to get it working only to have it go offline. Not very intuitive setup. Works 70% of the time and then just goes offline. Then all of a sudden it will connect again.

Fronius Symo 10 kw Inverter 10.0-3 208240L Advanced
It replaced a 15 year old inverter also made by Fronius. I noticed that it is much quieter. I also did all the installation myself, so it is a pretty straightforward process. Didn’t have to wait long for delivery and liked the store’s very informative blog

Fronius Primo 12.5 kW Inverter
Upgraded our old 6.6kw setup to a 12.5kw solar system with a Fronius primo inverter. So far, so good. I love being able to monitor the stats in realtime through the app.

Fronius Primo 7.6kW Inverter FRO-P-7.6-1-208-240
These guys conduct business exactly the way it’s supposed to be done. We did it a fair bit of research on different outfits in Central Texas, and met with several folks. What stood out about this company was the no-pressure approach, transparent pricing, communication, and all around professionalism

I was very pleased with my purchase. The information provided by a salesman was instrumental in my decision with which inverter to use. It saved me a lot of time and hassle having to deal with different sales people. They were friendly and knowledgeable and took the time to explain what inverter will be good for my needs.

Fronius Symo 12 kW Grid-tie Inverter 12.0-3 208-240
We bought a system couple of months ago. It’s currently providing about half of our monthly demand. Our system is somewhat limited by lack of roof space and the orientation of our property but I feel like are getting as much as possible out of it .
