50kW Three-Phase Off-Grid Solar System – 50kW

The system is built from two parallel systems. In case of a failure in one system, the other will continue to supply power at half capacity without interruption.

This powerful 50kW three-phase off-grid solar system is specifically designed for workshops equipped with three-phase machinery. The system delivers a continuous 50 kW of AC power, ensuring reliable performance for your equipment. With a substantial 96 kWh battery bank, it guarantees a steady power supply.

The system is also highly versatile and expandable. You can integrate a diesel generator for additional power support if needed. Additionally, it supports the inclusion of a DC car charger, enhancing its functionality for electric vehicle owners.

Shed roof installation $130K-$140K fully installed after rebate. Ground mount quoted separately

Full Occupancy Design for Long-Term Performance

We size for maximum bedroom capacity, not current usage, so your system supports future owners, growing families, and stronger resale value.

Redundancy Where Reliability Demands It

For larger or higher-risk properties, we can design dual or triple inverter redundancy to reduce single points of failure and keep critical loads running if one unit goes down.

Worst-Case Winter Solar Sizing

We oversize arrays for dark Ballarat winter weeks, capturing enough energy in short sun windows to recover batteries fast.

Battery Autonomy for Consecutive Low-Sun Days

Every system includes roughly two days of battery reserve, so poor weather doesn’t force lifestyle cutbacks or generator dependence.
