We're not a fly-in sales outfit — WISE Energy designs and assembles its battery systems at our Unanderra facility and our licensed electricians install across Wollongong, Shellharbour, Kiama, Dapto, Albion Park and the wider Illawarra. The SolarStore range (30, 50 and 50 PRO) is engineered off-grid-first, which means it handles blackouts and weak rural feeders better than grid-only batteries — and federal + NSW rebates can stack on eligible installations, including caravans, tiny homes and house boats.
What we install
Battery storage with new or existing solar, full off-grid systems with generator integration, hybrid switchboards for blackout protection, and EV charging. Commercial and utility-scale projects welcome. Every job starts with a free rebate check and a realistic savings estimate — no pushy sales calls, ever.
