"Best" depends on what your home needs, so this page answers it two ways: use-case picks that name the situation each battery suits, and a ranked list scored on a published formula — usable capacity, warranty length, how complete our verified spec data is, and price, with CEC compliance issues scored down regardless. We don't sell any of them; installers quote the actual price. For what the parts typically cost across the market, see our WA battery price index. Prefer a shortlist-style read? Our best solar batteries in Perth for 2026 piece ranks five.

No single battery wins every home, so these picks name situations, not champions — your usage decides which one is yours. Each links to our full brand profile.
Budget-disciplined, rebate intact
GoodWe Lynx Home F G2
A modular LFP stack priced under the comparable big-name rivals. Rebate-eligible with an eligible GoodWe hybrid pairing, so check the pairing before counting on it.
The rebate arithmetic
Sungrow SBR
The 9.6 kWh entry configuration sits just under the scheme's capacity cap — a rebate-efficient starting size if that's the budget driver.
Keep your existing inverter options open
BYD Battery-Box Premium
Pairs with high-voltage hybrids from twenty-plus brands, so the inverter gets chosen on merit.
Whole-home backup first
Tesla Powerwall 3
High continuous output and whole-home backup in one box — with the WA rebate off the table, a trade-off worth weighing in full.
First battery, one box
Alpha ESS SMILE
Battery, hybrid inverter and software as one decision, with a real Australian support presence behind it.
EV in the driveway (or the plan)
Sigenergy SigenStor
The only pick here with an integrated EV-charging module — you're paying for that platform, so it earns its keep when a car is part of the plan.
