Enphase Ensemble IQ8M Residential Microinverter Liquidation

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!

Enphase Ensemble IQ8M Residential Microinverter Liquidation

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!

Enphase Ensemble IQ8M Residential Microinverter Liquidation

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.

Enphase IQ8AC Microinverter Residential

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

Enphase IQ8 Microinverter IQ8-60-2-US

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.

Enphase IQ8PLUS Microinverter

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

Enphase Ensemble IQ 8H Microinverter

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

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.

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.

Enphase IQ Commercial Envoy 3-phase

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.

IQ Combiner 3 with Enphase IQ Envoy™

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

Great quality. As an installer myself, I really love Enphase products in general and their microinverters are top notch.

IQ Combiner 3 with Enphase IQ Envoy™

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.

Enphase IQ7A Microinverter Residential

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.

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.

About product

The Enphase Three-Phase Network Protection Relay comes together with Enphase IQ Envoy and Enphase Mobile Connect modem. The three constitute a ready-to-use solution for commercial three-phase 208 VAC solar panel systems. IQ Microinverters can function without the Network Protection Relay, however, it may be required by utilities or AHJs in accordance with IEEE 1547. The device constantly tracks the voltages to detect loss of phase. In case of abnormalities it disrupts the powerflow and automatically reconnects later.

Simplicity

The network protection relay and contactor are built in
Compact size and pre-wired components
Installation is easier with a backplate
Cable entries and exits are customizable
Up to 200 A input (AC)

Flexibility

Compatibility with three-phase 208 VAC systems employing IQ 7 Series microinverters
IQ Envoy allows to communicate with and control your PV system
Phase-wise performance tracking is possible with optional CTs
Wi-Fi, Ethernet, or cellular networking options
