At a Glance: Enphase Batteries Score 4.3 out of 5 – Excellent
Scoring is based on our solar battery scorecard which is consistently applied to each brand and battery available on the Australian market. This scoring reflects Enphase’s IQ Battery 5P.
$$$$$ Price: Based on data from Solar Choice’s network of solar installers, the average price for an installed Enphase battery is $1,465 per usable kWh. This places it in the as one of the most expensive options on the market.
- Company Backing and Trustworthiness (5 out of 5): Enphase has been active in Australia since 2012 with a substantial number of local support staff. With a globally strong brand and proven reliability in microinverter and battery technologies, it earns a full score for trust and backing.
- Warranty Offer (4 out of 5): Enphase offers a throughput warranty of 6 MWh per usable kWh (equivalent to 6,000 cycles), a 15-year product warranty, and a minimum capacity rating of 60% at the end of the warranty period. This robust offering ranks among the best available.
- Customer Reviews (5 out of 5): Enphase batteries have received strong customer feedback, with a verified average rating of 4.62 from 13 reviews on Solar Choice’s independent platform. This earns a perfect score under our review scoring system.
- Functionality (3 out of 5): Enphase batteries are AC-coupled, meaning they can be installed with virtually any existing solar system. They have UL 9540A fire safety certification and support modular battery balancing for expanding the capacity. However, they have a IP55 rating which is lower than some other leading batteries and are not stackable battery modules which adds to the cost of expanding.
Founded in March 2006 by Raghu Belur and Martin Fornage, Enphase Energy were the first global microinverter manufacturer. Fast forward to 2025 and Enphase’s have shipped approximately 82 million micro-inverters and are established as the market leader in micro-inverter technology.
Enphase first launched batteries to accompany their micro-inverter solution in 2019 and they are now on their 3rd generation of batteries which are primarily designed for residential use.
Enphase entered the Australian market back in 2012 and celebrated its NASDAQ launch the same year. Their local team currently operate from their Australian office in South Melbourne.
Enphase are currently on their 3rd generation of batteries which is called the Enphase IQ 5P Battery.
The IQ 5P battery combines 5.0kWh of usable battery storage capacity with 6 x IQ8D-BAT microinverters built in. The system can output up to 7.68 kW at its peak and sustain 3.84 kW of continuous power. This is suited to capturing the start up capacity of power hungry residential appliances like pool pumps or air conditioners.
Thanks to its decentralised design, even if one of the microinverters within the battery experiences a malfunction, the home continues to receive power.
The battery is relatively large measuring roughly 1m by 0.5m and weighing 79 kilograms. The battery can be wall-mounted or floor-mounted on a pedestal.
The battery uses the popular Lithium Iron Phosphate (LFP) battery technology which is known for is stable and safe characteristics. The solution integrates with the existing Enphase app.
One key point of different for this battery is its longer life expectancy than competitors with an industry leading 15-year (or 6,000 cycles) warranty.
The IQ System Controller 3 INT connects and communicates between your home, grid power, the IQ Battery storage system and your solar system. The device is required for an Enphase battery solution to be able to provide power during a power outage.
Based on pricing data from Solar Choice’s network of installers, the average cost of a 10kWh Enphase battery solution is $14,650 including the IQ System Controller and installation. This means they are around $1,465 per usable kWh meaning they are priced at the premium end of the market like their micro-inverter solution.
Installation costs will vary depending on your circumstances and there may be rebates available in your state. Additionally you will be able to reduce these costs with the federal battery rebate which will cover around $345 per usable kWh or $3,450 for 10kWh solution mentioned above.

Most batteries on the Australian market offer a 5-year or a 10-year warranty. Enphase’s IQ 5P battery comes with an impressive 15-year warranty or 6,000 cycles (whichever comes first). This is a point of difference and is a good indicator that Enphase batteries will outlast most others in the market.
Assuming the battery is cycling once per day, then 6,000 cycles allows for over 15 years of usage. The battery warranty maintains that the battery will support minimum of 60% of its capacity. The 6,000 cycles works out to be an equivalent throughput of 6MWh per usable kWh which far exceeds the industry norm of around 3MWh.
The battery warranty is backed up with their local team and office in Melbourne. For any issues you can contact them on 1800 006 374.

Our Verdict On Enphase Batteries
If your looking for the best, the Enphase’s IQ Battery 5P stacks up favourably against most solutions on the market. Perhaps the most key point of different is their strong backing and reputation as a brand coupled with the demonstrated longevity of their batteries. This becomes evidence when you compare their warranty with any other battery.
Overall customers who have installed an Enphase battery appear to be very happy with its operation and performance. The only issue for customers will be whether they can fit this into their budget with the premium price tag.

Reviews from Australians who have installed Enphase Batteries
Rated 4.62 from 13 reviews
Robert Brown, first its more than 10YR lifespan for the Enphase ACB. Second, you’re going by utility rates now with no guarantee they will remain fixed over the next decade or so. Another hidden attribute of the AC Battery is that it is a decentralized power topology and not centralized with a single point of failure. That true fault tolerance and reliability to the customer has to be worth more than a centralized residential storage solution.
I have never read so much b*** in one place. Your article so mislead, it is really only a test for the stupid. From your own data on savings which is questionable. The battery saves $400 per year, costs $7000 upfront and last 10 years. You can easily work out your total savings over the 10 year lifespan is $4000 yet your total outlay is $7000. Total savings negative $3000! And I did not even take into consideration value of money over time as the $7000 is an upfront payment where the $4000 is over a 10 year period.
Hi Robert,
Thanks for your comment.
We’ve tried to ensure that our analysis is fairly straightforward, and we’ve clearly displayed the ‘battery only’ payback periods in each of the tables. If we were misrepresenting – or not showing – these numbers, you might have a case for calling it b***s*** but that’s clearly not what we’re doing here. This is a level-headed analysis of a product that a lot of people will come across as they do their research.
As a comparison & advice service, we don’t sell any products ourselves, and our site (and quote comparisons) are devoted to helping people make an informed decision about going solar and/or getting batteries. Our battery calculator (linked to multiple times in this article) will help anyone work out ballpark figures on their own – without any ‘rose coloured’ results.
Residential battery systems are gaining a lot of steam in Australia. You’ll note that a large portion of this article is devoted to explaining how batteries work generally, with a specific focus on Enphase’s AC Battery. It’s our hope that anyone who reads it comes away feeling that they’re in a better position to making a decision about whether to get batteries for their home – even if that decision is to hold off on purchasing them for now.
