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 Southbank, Melbourne.

Enphase Battery Models and Options

Enphase are currently on their 3rd generation of batteries which is called the Enphase IQ 5P Battery.

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.

IQ System Controller 3 INT

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.

How Much Does an Enphase IQ Battery Cost?

Roughly speaking, one Enphase IQ 5P Battery will cost about $10,000 including additional components like the IQ Systems Controller and installation. This means they are around $2,000 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.

Enphase’s Battery Warranty For Australian Customers

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).

Assuming the battery is cycling once per day, then 6,000 cycles allows for over 16 years of usage. The battery warranty maintains that the battery will support minimum of 60% of its capacity. This allows for a reasonable amount of degradation of performance of the 15 years.

The battery warranty is backed up with their local team and office in Melbourne. For any issues you can contact them on (03) 8669 1679.

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.
