a nice inverter for a small system. really worked wonders for me. pretty easy to set up too.
Great article I would have spent hours figuring it out by myself:) so far inverter running great!
Good value on this inverter thanks.
We purchased this inverter from A1solarstore four months ago for our parking complex and since we’ve promised them a review, here it is. Overall, we are satisfied with the delivery and performance. The installation indeed was simpler than we anticipated. Our system is only 40 kW and the inverter handles it well. It is somewhat loud, but honestly, it’s not much of a problem for us. One of our employees can manage it though his smartphone, but so far there was simply no need for it.
Thank you for your help! The service was great, we are very happy with the purchase!
A1solarstore was very helpful along the way. Me and my wife used the solar calculator to size a system and picked this inverter. Highly recommend
PACKAGE ARRIVED THANK YOU
This inverter is quite small, but it does its job. I found it very convenient for my needs: I can watch the performance of my system wherever I want. Feels good to go solar.
Really simple installation
We’ve bought this inverter along with the panels (Canadian Solar). Our system is small, and this Sunny Boy fits it well. The shipment was fast and so far our solar project is going great.
The inverter is good. We installed it at our shop in Berkeley. It currently is at our roof next to panels and AC unit. No complaints, it’s quite easy to manage. Robert
It is one of the best solar companies and I was pleasantly surprised with their customer service.
I am writing to express my sincere thanks for the help that A1 Solar has given me in the selection of my new inverter. Thank you so much.
Everyone was knowledgeable and pleasant to work with and did a good job of responding to various questions about technical issues of the product.
I was searching for solar companies online and got quotes from several of them. I evaluated them not just based on their price, but also how much information those people giving me the quotes could give me about why they were choosing that system. I decided to go with A1 Solar by my impressions of how organized they were. I had another company that I was looking at who failed to get back to me in a timely manner several times, and so I eliminated them.
Solar representative was knowledgeable, patient and professional answering all my questions about the inverter I needed. Thank you.
We had a high electricity bill and wanted to be more environmentally conscious. We went solar and it was a very good experience overall. The custom service was excellent.
Great service and excellent staff. Most of them are very responsive and attentive to customers' questions. I had a complicated case and they responded with professionalism and patience and I highly appreciated for their efforts to smooth the entire process. Highly recommended.
Honest and professional company that made us feel welcome. Thank you.
Very professional and we love our electric bill.
Exceeded my expectations! Very customer dedicated! Knowledgeable and friendly!
When I called A1 Solar, they were very friendly. They told me what kinds of inverters they had and I liked that they had what I wanted. I'm really impressed with everything.
Great crew from start to finish. They were polite, knowledgable & answered all of my questions.
Given how much searching and research I’ve done I can only applaud your service.
I will be referring you to anyone else I know who is interested in solar.
I was really impressed with their salesperson and they knew what they were doing. They’re an excellent company to work with.
