Fantastic inverter. Works perfect with my high watt panels. Smooth install and zero noise.
Got the Enphase IQ8HC installed last month and honestly couldn't be happier. Love that it's made in the USA
Easy to install and works flawlessly. The Enphase app makes monitoring a breeze. Very happy with this purchase!
This solution is a real game changer. It works like a hybrid inverter, forming a microgrid during a power outage. A1 still has the best prices, despite the high demand and chip shortage. Keep it up, guys!
The basic IQ8 wasn’t powerful enough for my panels, so I was advised to look into the IQ8M. They are the same thing, but the input power and peak output are different. Can’t wait to see them installed!
Have been waiting for the IQ8 ever since I heard about it back in 2017. Now the day has finally come. A1 didn’t make me wait longer than necessary, I just ordered a pick up and got the devices in a little over two days.
Running four of these and they’re all perfect. Best microinverters on the market.
works good no noise stable output every day very happy
Super easy to install. Compact and light but powerful. Been running for months no problem at all.
Fantastic inverter. Works perfect with my high watt panels. Smooth install and zero noise.
Highly recommended, parts and seevices
i like how each panel works on its own no shade problems
Super easy install for our warehouse roof system very happy.
it was surprisingly easy to set up

They work fine, I’ll post an update after the first few months of use

We already had a microinverter based system to begin with, but decided to replace them with this new model from Enphase due to frequent power outages. It was surely worth it! Can recommend to the people in the same situation

Have been buying Enphase microinverters almost from the moment they appeared on the market. Most of the first units are still in good working order. The IQ8 seems just as robust.
Picked the plus version for higher wattage panels. Very excited about their ability to operate off-grid, this is a very welcome feature in microinverters. The store processed my order very rapidly, this deserves a solid 5 star

It’s too soon to write a review, but so far the IQ8 looks great. The 25 year warranty is a huge advantage compared to the standard warranties for string inverters. I hope not to use it, but it gives some peace of mind

Really impressed with how fast after the release date I managed to get these IQ8+. A1 does wonders, can’t recommend this store enough!!!
By far the best solar store! Fast deliveries, low prices and very knowledgeable staff
I think it’s the most technologically advanced inverter currently on the market. I see it as an ultimate solar inverter that’s definitely worth every dollar!
The delivery was a bit slow. but it’s fedex that is to blame. as for Enphase — the quality and performance are superb to me.
Received the envoy fast and installed it. Had to call Enphase once, but now it's up and running. Great job!
The staff of a1store recommended this model to me. To me these inverters feel very good so i’m satisfied. Also it was a pleasant surprise that the shop didn’t charge for delivery of those.
This is a MUST for any solar panels that use Enphase microinverters. An expensive solar energy system should be continuously monitored for correct operation and ongoing maintenance. The Envoy is a very effective tool to check the condition of all microinverters used in the solar array. Highly recommended.
These are great cables providing solid connection
Great cable at a great price!
They work fine, I’ll post an update after the first few months of use
I have way too many good things to say about the device to write them all down. I just want to thank the shop for a speedy delivery and unrivaled service.
I’m planning to buy and connect the batteries to this unit in just a few weeks. Our system (but for the panels, of course) is in our basement. We own twenty 400W panels equipped with the IQ7A microinverters
I really like enphase products, and this one is no exception. Consumption monitoring is very precise and the included modem works perfectly. very satisfied with the purchase
got the package, thank you very much.
thanks for the fast delivery. just connected it to my ipad, everything works fine
It took quite a while to upgrade to the newest software, but after that it started to work just fine. No problems. Thanks
Great quality. As an installer myself, I really love Enphase products in general and their microinverters are top notch.
The material of the box is very durable. The components inside are protected from the elements and there is a specifically designed vent on the left side. The Envoy IQ is already installed, and all this for a reasonable price. I couldn’t have made a better purchase.
i actually used a standard inverter before, but it broke down eventually. This time i've chosen these things and they were so easy to install! Honestly, now i don’t even know why would you choose a string inverter when you can have a batch of microinverters.
In my area this device is obligatory. In my case that was the main reason for purchasing it. The unit was very easy to install
The store is a pleasure to work with and fulfills even the largest orders in time. Definitely recommended
Perfect after five months, thank you!
Thank you very much for all your help. You have been very helpful and have always been there to answer my questions!
Very easy customer service experience. Thank you. Hope and other customers can find the same comfort and same experience.
Thank you very much for that extra work you have put in. Great customer service.
What a treat to deal with a group who keep their commitments and who are so co-operative – and at a competitive price. Thank you.
Thanks for your awesome customer service and technical support. I am so pleased with the battery you sold me.
Everything went well. The sales service has been attentive and effective.
Everyone from the first phone call to the last has been a pleasure to deal with. All requests were dealt with promptly and without question.
Initial experience was great. Sales person was helpful and my inverter went up quickly.
When I made my purchase, I had a few questions, so I emailed customer service. They were so kind and understanding about my problems. I got a response very quickly and they just treat you like family. The value is extremely high due mainly to the quality of the product and the money I save on my energy bills each month.
