24kW Off-Grid Solar System Sigenergy

This system is tailored for a family of 4 to 5 residing in an all-electric home, providing the ability to use up to 12 kW of power, surpassing the typical grid-connected home allowance which is often limited to 40A, approximately 10 kW. Furthermore, it features a large solar array capable of charging the 32 kWh battery bank in less than two hours on a sunny day. The ample battery bank can sustain an average house for approximately 24 hours, ensuring consistent power even during periods of high demand or low sunlight.

The advantage of this configuration is its dual-system setup operating in parallel, which ensures that in the event of a failure in one system, the other will seamlessly continue to provide power supply without interruption.

This level of system is typically suited to larger all electric homes, families with higher daily energy use. And so for properties where energy security is a priority. If that sounds like your situation, the Ultimate 4 Bedroom Off Grid is also a good place to start.

OccupanCY Target

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.
