Quietly powering a Scotsburn winery, this off grid system turns sunlight into certainty. Built for the rhythms of a working vineyard, it supports every season from first light to last pour.
Two inverters. One system. Built-in redundancy from day one — if one fails, the other keeps running. This TwinGuard installation near Ballarat currently runs 12kW of solar on a newly built home and is wired to scale all the way to 24kW when demand grows.
A professionally installed off grid energy system delivering reliability, clean integration, and long term performance backed by deep technical expertise.
