Coastal · Salt air reality
Coolum bills run high — aircon against the humidity, all summer. Solar kills the biggest chunk of it, and a battery banks the rest for the evening peak and the odd storm outage.
Salt air eats cheap gear. Budget inverters and fittings corrode within a few years here — that's why I only install Tier-1 gear with proper IP ratings and real warranties.
Aircon is the bill. Solar sized to your daytime cooling load cuts most Coolum power bills by 70-90% in summer.
Storms take the grid. Coastal cells drop power several times a season — a battery keeps the fridge, WiFi and fans on without a thought.
Straight answers

Most residential systems are done in a day, grid-connected and app-paired the same week.
About $252 per usable kWh on the first 14 kWh — roughly $3,500 off a 14kWh battery. It steps down on 1 Jan 2027.
