Description

DEYE AI1 Stackable Battery System – Single Phase

A compact, modular single-phase solar and battery system for Australian homes, available with 5kW, 6kW, 8kW or 10kW DEYE AI1 hybrid inverter options.

The DEYE AI1 combines a low-voltage hybrid inverter with a floor-mounted AI-W5.1-B LiFePO4 battery stack. Internal blind-mate connections keep the stack neat, while the modular design lets an installer size the system from 5.12kWh to 30.72kWh nominal capacity in a single stack.

This is a system-range listing rather than a one-size-fits-all kit. We will match the inverter, battery quantity, PDU/base, backup arrangement, solar input and protection equipment to the property before confirming a final supplied or installed price.

Why choose the DEYE AI1?

  • One coordinated platform: DEYE inverter, PDU and AI-W5.1-B battery modules are designed to work together.
  • Scalable storage: one to six 5.12kWh modules provide 5.12kWh to 30.72kWh nominal energy per stack.
  • Fast backup response: the series brochure specifies a 4ms switching time when correctly designed and commissioned.
  • Smart energy control: supports self-consumption, time-of-use operation, peak shaving, smart load, generator input and AC coupling.
  • Indoor or sheltered outdoor installation: IP65 after stacking. The manuals still require protection from direct sun, direct rain and unsuitable environments.
  • Long-life LFP battery: 90% recommended depth of discharge, at least 6,000 cycles under the stated test conditions, and a 10-year product warranty subject to DEYE terms.

What is included in a configured system?

  • 1 x selected DEYE AI1 AU hybrid inverter
  • 1 x compatible AI-W5.1 PDU and floor base
  • 1 to 6 x AI-W5.1-B 5.12kWh LiFePO4 battery modules
  • Required interconnects supplied with the selected DEYE components

Not automatically included: solar panels, site-specific switchboard work, backup circuits, gateway/meter options, freight, installation, network applications and other balance-of-system items unless shown in your written quote.

Installation and approvals

Battery quantity, usable backup power, PV string design, phase configuration, generator integration, clearances and protection must be confirmed by a suitably qualified designer and installer. Clean Energy Council product lists are dynamic, so the exact inverter and battery model must be checked against the current lists and the applicable network requirements at the time of quotation and installation.

The battery stack is heavy: each battery module is 53kg. The AU manual calls for at least two people to handle a module and specifies floor mounting, a clean flat installation area and clearances around the equipment.

Tim Stokes
Awesome service. Very knowledgeable. I have bought a number batteries from them and great experience each time.
Robert Robins
Purchased a Growatt Spf5000es inverter, pricing was very competitive and service was great. Highly recommend
Bruno Drinovac
Purchased a Deye inverter from LiFePo4 in June 2026. I am pleased to say that the inverter has been running perfectly with no issues for the last 1½ months. It has been installed into an off-grid system on a very recently built granny flat. This inverter was ideal for our situation and was easy to set up. The 2 trackers were very handy as we needed to deal with 2 different sets of strings operating at 2 different voltages. It certainly looks like a very well designed and robust inverter and will hopefully last us many, many years. If and when we need to replace the inverters on the main house, we will certainly be looking at using Deye.
LiFePo4 provided free delivery, which was very quick, arrived in only a couple of days. They sent me an email checking on how we were going with the installation and offered assistance if we needed it. Excellent Company to deal with and I would purchase from them again in future.

Been buying batteries from LIFEPO4 Australia for years, always A grade! Great to deal with. Great after sales support. Recommend highly.
Russell Vosseler
Mark and the team have done a great job finding the best solar and battery solution for my house, my parents house, and also friends' houses.
Their batteries are top quality, not like the cheap and nasty ones you find with "special low deals". Best to pay a little extra and get quality products.
Their aftersales service is exceptional with continual support after installation. Mark had provided guidance months after installation to maximise the production of my inverter, and continues to provide valued suggestions even now. 😀
Ken Baker
just received my 30 jinko panels this morning...from initial enquiry to delivery in metro adelaide was 4 days!...on top of that LifePo4 beat the other quotes on price so needless to say I am very happy with the purchase. highly recommend

I can’t speak highly enough of Mark at LiFePo4 Australia – they’ve now saved our motorhome adventure twice!
The latest drama hit when our battery failed mid-trip, leaving us in a power pickle. Even though it was outside business hours, Mark jumped on the phone and organised a replacement battery with lightning-fast turnaround.
This is the second time Mark has gone above and beyond for us – always friendly, knowledgeable and genuinely committed to getting you sorted. Couldn’t recommend them enough.
Response from LiFePo4 Australia

Thanks Steph. I'm glad we could assist. The cells you picked up before finding us at LIFEPO4 AUSTRALIA might have been B grade. We are glad we could help out with the 2 cells so far. If any of the others drop out, I'll send out replacements as quickly as we can. Enjoy your travels

Peter Demol
I had an excellent experience buying components to assemble 2 battery packs. Mark is extremely knowledgable about the products he sells. He answered all my questions, prices are excellent, and when there was a potential issue, he went over and above by supplying extra products at no extra cost. Shipping halfway across the country to a rural area took only 3 business days which is insanely fast. I am totally happy with my new batteries and with Mark's excellent customer service. After 10 years of FLA batteries, finally going to lithium technology is heaven. Thanks again Mark. Very happy customer.
Vicki Wattus
Awesome customer service, Mark went above and beyond in sorting my order when we ran into a few snags with it. I would recommend this company to anyone who values good price, service and a great customer experience.
Response from LiFePo4 Australia

It was my pleasure Vicki, we love helping out especially those who need a little bit of help. We hope your get years of service from the Victron MPPT and Jinko 510W solar panel, thanks for you patience over the weekend while we arranged the shipping for the panel to the depot nearest you. The $200 we saved on shipping, was well worth the delay over the weekend. Safe Travels Mark

Absolute legend of an owner great 10 star customer service and product and knowledge to match..!!!
Not just a salesman...anything but absolute legendary service and knowledge to suit..

Cells arrived, a bit of a delay. But overall we'll priced and packaged.
garry miille
Mark knows what he is talking about when it comes to batteries. Great pricing and very helpful too. Just a great experience all round.
Dapper Rausimen
I totally agree with the other 5 star reviews and can highly recommend buying lithium cells from this business. I received my order of 72 automotive MB31 batteries quickly and I am very impressed. All the cells were within 0.01 of a volt so didn’t require balancing or top charging before installing. They are the real deal A+ automotive grade EVE cells as advertised and not B grade rubbish some online sellers are supplying. Mark actually answers the phone if you need to discuss anything before purchasing and is one of the few people I have found selling lithium batteries that actually now’s about how to install and set voltage settings in the BMS’s he sells.
Elliot C
Super helpful gentleman. I barely prompted him and he gave me plenty of important and useful information. Best customer service I have had in as long as I can remember.
