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.

| 10kW | AI-W5.1-10P1-AU-B | Supplier-listed AU model; current approvals and stack design must be confirmed before quoting. |
Stack capacity options
Each AI-W5.1-B module adds 5.12kWh nominal energy. The figures below are from the Australian three-phase manual and apply to the common battery stack.
| Stack | Nominal | Usable | System height | System weight |
|---|---|---|---|---|
| 1 module | 5.12kWh | 4.6kWh | 569mm | 74.5kg |
| 2 modules | 10.24kWh | 9.2kWh | 850mm | 127.5kg |
| 3 modules | 15.36kWh | 13.8kWh | 1,131mm | 180.5kg |
| 4 modules | 20.48kWh | 18.4kWh | 1,412mm | 233.5kg |
| 5 modules | 25.60kWh | 23.0kWh | 1,693mm | 286.5kg |
| 6 modules | 30.72kWh | 27.6kWh | 1,974mm | 339.5kg |
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.
