Page content is loading, please wait.An honest, independent look at every major home battery brand in Australia — plotted by price vs. real-world value to help you make the right choice.
About this chart: Positions are based on installed price per usable kWh (including federal rebate where applicable), warranty terms, cycle life, Australian support quality, installer sentiment, and real-world reliability data as of February 2026. We install Neovolt, Fox ESS, Swatten, Sungrow, and Goodwe systems.
The X-axis represents installed cost per kWh (left = cheaper, right = more expensive). The Y-axis represents overall value (bottom = lower value, top = higher value).

Each quadrant tells a different story about a brand's market position
Best bang for buck. Low installed price, high capacity, strong warranty and support.
Brands: Neovolt, Fox ESS, Swatten, ESY, Anker
Top-tier quality and features, but you pay a significant premium per kWh.
Brands: Tesla, Sigenergy, BYD, Enphase, Sungrow, Fronius
Low price but concerns around support, warranty claims, quality control, or longevity.
Brands: Ruixu, Felicity, VARTA, Opal, Red Earth, Eguana, Bluetti, Growatt, Sofar, SolaX, Pylontech
High cost without proportional value. Ecosystem lock-in or unproven technology.
Brands: SolarEdge, LAVO, Redback, Generac, Panasonic
Brands like Neovolt, Fox ESS, and Swatten have completely disrupted the market by offering 40–50kWh+ systems at prices that used to buy you 10kWh from premium brands. With the federal rebate reducing in May 2026, these value leaders offer the best way to maximise your savings before the cuts.
Tesla and Sigenergy are excellent products, but at $1,000–1,500/kWh installed, you're paying 5–10x more per kWh than value leaders offering equivalent LFP chemistry, similar cycle life, and comparable warranties. The “premium” often buys a brand name and a nicer app — not better batteries.
No-name brands like Ruixu and Felicity might look tempting at face value, but with no local support, questionable quality control, and uncertain warranty enforcement, a failed battery at year 3 costs far more than paying a bit more upfront for a proven brand with Australian support.
Brands like Growatt, Alpha ESS, and Sofar sit in a tricky spot — not cheap enough to be true budget picks, not established enough (in AU) to justify mid-range pricing. They're improving, but we'd recommend spending slightly less for a value leader or slightly more for a proven premium brand.
From May 2026, the federal battery rebate drops significantly — especially for larger systems. Here's how homeowners can still get value, and who we believe will lead the market.
85%
Rebate reduction for batteries over 28kWh — the sweet spot most homes need
2x/year
Rebate now declines every 6 months instead of annually — faster erosion of value
$8,000+
Potential rebate loss on a 48kWh system if you wait past April 30, 2026
Lock in a 40–50kWh system before May while the rebate still covers large batteries. Post-May, the rebate per kWh above 28kWh drops to just 15% of the current rate. A bigger battery now pays for itself faster through greater self-consumption and VPP earnings.
Without a big rebate cushion, the price gap between a $1,200/kWh Tesla and a $150/kWh Neovolt becomes even more significant. The same LFP chemistry, similar warranties — the value brands deliver the fastest payback period, rebate or no rebate.
With rising electricity prices and growing Virtual Power Plant programs, large batteries earn money by exporting during peak demand. A 48kWh system can earn $500–1,500/year in VPP payments alone, accelerating your payback regardless of the rebate.
Post-rebate, every dollar counts more. The brands that win will be those offering the lowest total installed cost per usable kWh with reliable warranties. Marketing budgets and slick apps don't reduce your power bill — capacity and efficiency do.
The ACCC has issued safety recalls for several battery brands due to overheating and fire risk. Before purchasing any battery system, check the ACCC Product Safety recalls page.
VARTA — Insolvency + safety recall. Do not install.
Opal — Overheating risk recall. Avoid.
Red Earth — Included in ACCC recall. Limited support.
Eguana — Recall + uncertain company future.
Redback — Older models recalled. Research carefully.
LG RESU — Older models recalled (replaced by new line).
Price (X-Axis): Installed cost per usable kWh including federal rebate. Based on typical AU retail pricing as of Feb 2026.
Warranty: Length, coverage terms, and ease of making claims in Australia.
Cycle Life: Manufacturer-rated charge/discharge cycles before capacity degrades.
AU Support: Local office, response times, spare parts availability, and installer feedback.
Reliability: Real-world failure rates, firmware stability, and long-term performance from installer community.
Value (Y-Axis): Composite score of all above factors weighted by importance to homeowners.
