Installed estimates including GST, before rebates. Quotes vary.
SAJ's home batteries use LFP cells. LFP (lithium iron phosphate) is the most common residential chemistry in WA for its long cycle life and stability in Perth's heat.
WA's rebate ($130/kWh, up to $1,300) depends on the system pairing with a Synergy-approved (SSL) inverter — eligibility is set by the inverter, not the battery brand. Whether a given SAJ system qualifies depends on the inverter it's installed with, so confirm the pairing with your installer.
