About Enphase, Solar Inverters

Enphase solar inverters review

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 expects to have a bidirectional EV charger available in 2024.

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backup" as a limited solar-only blackout protection feature, however it was never released in Australia and has been withdrawn in the US.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 2023 SolarQuotes Installers' Choice Awards, Enphase kept its second spot from 2022 for the best inverters, as voted by installers in our network. The company also scored second 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 offer a 10 year warranty on its IQ7 and 15 years on IQ8 microinverters (extendable to 20 and 25 years), covering defects in workmanship and materials.

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.

the Enphase App is easy to use and clear to see how much energy is being produced or consumed at any point in time.

It's still early days but the Enphase equipment seems to be working as specified and the app is very good. I am having some difficulty reconciling the app figures with the Energy Australia billing figures but due to the Christmas period, I haven't contacted anyone yet

At this stage we are glad we went with micro inverters, both for the effectiveness of the overall system and for future proofing in case we decide to add more panels.

After nearly 4 years of use I’m pretty pleased with the Enphase micro-inverters.
We have a non-ideal roof for solar with multi-aspects, but not much in the sense of northerly. So opted for 4 westerly arrays and 1 easterly, and the microinverters do a good job at getting the best out of each panel.
The best thing about the micro-inverters is the single panel monitoring. I’ve had 2 panels fail in 3 years and 1 is starting to show a pretty sudden 30% drop in output. I’ve also had a microinverter fail. So that’s why I’m not giving it 5 stars.
Also, must note that the installer’s subcontractor no longer services my area, (Newcastle) so when I’ve needed a fix under warranty, it’s taken months to get a technician out from Sydney. I thought going with a bigger company like Solargain would avoid the risk of using a small company that goes bust - leaving me high and dry for warranty issues. I also thought Newcastle wasn’t a distant outback station. So I’m not impressed with Solargain’s service with their retreating to the capital.

Enphase App is easy to use but be careful not to get addicted to watching the solar production on your digital device for FOMO on a spike or glitch.

The enphase inverter and microinverters have an excellent reputation and excited to be using this brand. My system is working perfectly. I am less enthusiastic about their monitoring app.

We bought 28 JinkoTiger N-Type 66TR 415w panels with a 25 year product & 30 year performance warranty coupled with an 11.62KW Enphase (10kw) system) consisting of 28 Enphase IQ7A Micro inverters with a 10 year warranty. So far we have exported to the grid over five times what we have imported, so we are no longer getting electricity bills - in fact, the retailer pays us.

The only criticism is that Enphase have not addressed the issue with the iq8 and REC Alpha panels so it means installing the iq7x with those panels.

After much research I do like the individual micro system and individual monitoring and efficiency, I do believe the optimisers are still a great dc solution too with SunPower inverter should you wish to stay with dc string systems. I will have to give this 10 years to be fair but I like the latest and greatest technologies with reputable back up so I’m sure this will be great.
