Finn's Enphase Inverters Review & Verdict
Finn Peacock has been a Chartered Electrical Engineer since 1998, and is ex-CSIRO
The fact that I've got 34 Enphase IQ7 microinverters on my roof should tell you what I think of their quality.
Most people don't *need* microinverters, but if you want microinverters, there's nothing wrong with that, and - in my opinion - Enphase are the only game in town worth considering.
I like their reliability and flexibility. I'm not a fan of Enphase's self-centred attitude that makes it so difficult for others to interface with their microinverters. That means you are stuck with Enphase's crappy app for monitoring and tough-cheese if you want to automatically curtail your solar output to avoid negative feed-in rates - unless you are game to homebrew your own control system that triggers some relays...
My opinion: great hardware, not so great software, crap corporate attitude. But the hardware is so good I still bought them for the family home.
Enphase Inverters: Pros & Cons
- Invisible and safe
- Easy to wire with flexible deployment
- Scalable and efficient
- High quality with good warranty and support
- Expensive
- Closed shop, difficult to service and limited panel compatibility
- A roof is a hot environment for electronics
- Powerline comms prone to interference
- Poor app
About Enphase
Enphase Customer Service: 03 8669 1679
Enphase Energy is a US-headquartered manufacturer specialising in the development of microinverters for the solar market. Enphase microinverters are miniaturised inverters that work on a per-panel level. It's a very different approach to a single string inverter working with multiple solar panels, as is more commonly the case with solar power system installations.
Given their panel-level operation, Enphase microinverters offer a number of advantages over string inverters; including redundancy, more flexible system design, monitoring of individual panels and enhanced safety. However, be prepared to pay quite a bit more for a microinverter-based system.
The company's eight generation microinverter, the Enphase IQ 8 series, is suited to residential applications and commercial systems.
With around 63 million units all told shipped as at mid-2023, Enphase Energy is widely considered as the global leader in microinverter technology. The company has cultivated a solid international profile thanks to offices located across the world, including France, Italy, the United Kingdom and China.
Here in Australia, Enphase serves local customers and provides technical and commercial assistance via its office located in Melbourne or, for our visitors from New Zealand, in Christchurch.
Enphase also produces solar batteries, communication gateways, monitoring systems, installer toolkits and accessories, as well as other energy-related services. The company also working on a bidirectional EV charger, but despite announcing this back in 2023, it's not yet available.
While the company is based in California, Enphase manufactures its products via partners in various locations, including Mexico, India and China. In late 2022, Enphase announced plans to also open multiple manufacturing facilities in the USA by the second half of 2023.
Enphase IQ8 and battery-less backup
Enphase did advertise what they called "sunlight backup" as a limited solar-only blackout protection feature, however it was never released in Australia and has been withdrawn in the US.
The SQ Verdict On Enphase
Enphase is currently listed on my recommended inverter brands chart, meaning it's a brand I'd be happy to install on my own home (and I have).
In the 2024 SolarQuotes Installers' Choice Awards, Enphase kept its second spot from 2022 and 2023 for the best inverters, as voted by installers in our network. The company also scored third place in a new category; best after-sales support.
If you have Enphase microinverters installed at your premises, please feel free to share your experience with us and other Australians by leaving a review. Enphase microinverter reviews from Australian customers who have had the devices installed can be viewed below.
Enphase Microinverter Warranty Notes
Enphase offers a 10-year warranty on its IQ7 and a 25-year warranty on its IQ8 microinverters (as of October 2024), covering defects in workmanship and materials. IQ8's installed prior to October 2024 have a 15-year warranty.
If you have an issue with any of your Enphase microinverters, your first step should be to contact the original installer for a remedy. Despite any claims otherwise, if they are still in business they are the ones liable for the repair/replacement of a faulty microinverter, assuming it is still within its warranty period.
If your original installer has gone out of business or is no longer contactable, warranty claims must then be lodged by you through Enphase.
Here's how that works:
Enphase advise that customers should visit their website and use the prominent “Find an installer” button (located in the top-right) to locate an installer in their area. The chosen installer will make a site visit to diagnose the problem, and then work with the company to arrange a replacement. Enphase provide up to $100 towards labor reimbursement costs.

After paying Enphase to access their 'manager' software for a month I was able to confirm phase by phase assignment over my east, north and west facing sub adrrays was even and extends my producing day as expected. Solargain were not interested in helping me confirm these details.

Its working a treat!!
I can see exactly which panels are performing and I'm secure in the knowledge that if one panel in a bank is off line due to shadows, mechanical or electrical failure, bird droppings etc etc the rest of the system will soldier on but we've had absolutely no issues yet..just smaller power bills!!

Data reported in the enphase monitoring app and portal regarding Imported and Exported kWh agrees with data extracted from my smart meter to within +-0.1 kWh - which is important as it means the system is working perfectly.

Today is raining and cloudy but the panels have still managed to produce over 13kWh of power, well in excess of what we have used. This has surprised us as we hadn't expected such efficiency on a non-sunny day. The Enphase IQ7 + Micro Inverters system is ideal for our situation ,which includes panels facing north and east, because it allows each panel to produce it's own power independently of the others.

The enphase microinverters ensure that the output from each panel is maximised. A record of each individual panel performance is available together with overall system performance in 15 min. intervals.
Although my system is only 3 months old, these microinverters have not had any issue whatsoever. I am pretty confident that the IQ7+ series are well established and will last the duration of the installation.

Winter power production is quite poor. I do not know if the Fronius would have been any better; but as I am now installing a battery, I would have been better off with a more flexible inverter. In hindsight, it would have been better to have saved $1300 and gone with the Fronius.

The only “downside” is that it makes one aware of how much performance is lost in the solar panels when there are clouds or shade.
The flip-side of that is the “upside”, where we now shift our energy usage to the brighter moments, when we can.
