Battery series · Enphase · 1 size, all CEC-active
One size, 5 kWh usable: below the smaller-home band.
Each size is its own CEC listing with its own page. Household bands are the owner’s guide; rebate fit is against the WA scheme’s cap.
WA rebate fit: Under the cap
Household band: Below the smaller-home band
Full specs , 5 kWhThe WA Battery Scheme pays $130 per kWh on the first 10 kWh, capped at $1,300. Capacities under 5 kWh receive nothing, and every capacity from 10 kWh up receives the same $1,300. A larger battery does not earn a larger rebate. Whether a particular product qualifies also depends on it being Synergy-approved. “Over the cap” does not mean you should not buy it; the extra capacity is simply at full price. Figures come from each size’s own CEC listing; SBP holds no verified per-size pricing for this series.
The IQ Battery 5P uses Enphase's microinverter approach. Each 5kWh unit contains four embedded microinverters delivering 3.84kW of continuous power. If one microinverter fails, the others keep operating.
Each unit offers 5kWh of usable capacity and stacks up to 16 batteries for 80kWh total. AC coupling means it works with any existing solar system, although pairing with IQ8 microinverters opens the full Ensemble feature set.
Grid-forming means the system can restart solar production during a grid outage without a grid reference, a feature many AC-coupled systems lack. The Enlighten platform shows per-microinverter data.
The 15-year warranty (or 6,000 cycles at 60% retention) is among the longest on the market and reflects confidence in LFP cycle life. The trade-off is more hardware per kWh, which raises upfront cost and footprint compared to monolithic batteries.
For Perth installations, the LFP chemistry and IP55 rating cope well with the climate. The modular design suits homes with space constraints or planned future expansion.
