Fronius Primo 12.5 kW Inverter

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.

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(

man, i love the production. feels like 2 mppts do make a difference. really nothing to complain about here, great inverter, very happy with it.

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

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

Great 10 year warranty that shows the confidence of the manufacturer in its product. It was a pleasure to work with you, thanks a lot

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.

We have this wonderful piece of hardware hooked up to our 10 kW Solar system. Solid, responsive, easy to connect and monitor, what else to say. Happy with the purchase.

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

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.

It’s a very reliable and functional inverter, I say that after working with Symos for years.

It is a nice solidly built unit with lots of advanced features. Hope it functions well for long

Nice and small. Love the design. The service was good too!

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

FANTASTIC customer service! I originally called another solar installation company, and after having them NEVER return my phone calls, I decided to give A1 solar a call. I’m SO glad I did! Everyone is extremely knowledgeable and helpful.

A1 solar is a very professional and knowledgeable organization. Their staff is very knowledgeable, experienced, and thorough. We would definitely use them again.

Very professional, great help finding the right product for building.

We had a really great experience with this service. I’d recommend them to anyone who’s thinking about solar.

I had an extremely pleasant experience with you guys. Simple, responsive, informative, and brilliantly executed. Highly recommended if you are shopping for solar. Thank you.

Professional, reliable and responsive. Highly Recommended!

I appreciated the very quick responses to all questions and concerns even in the evenings and on weekends.

We have been pleased with A1 solar and our system which is providing power for our business.

Great service and communication! Honest salespeople, good value.

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.

Had a great experience for a first time solar person. They answered all my questions in a timely manner. Thank you.

Very professional group of folks. Everyone was helpful. Thanks so much. I’m a month in and already ahead of my daily usage!

Really attentive and knowledgeable crew, and support staff. Excellent communicators; great ethics and transparency with the customer.

Not knowing much about inverter myself, they explained everything I had questions about. I feel confident that they set me up with a good system.

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 .

The company was professional and courteous. We enjoyed working with them.

Excellent customer service Our electric bills are down to the basic service charge of around $11 per month.
