100UP 12–16 Off-Grid Solar

Powerful, Redundant & Ready to Expand. This off-grid solar system is built for full-time living in homes or rural properties. Designed for modern energy use, it comfortably runs appliances, heating, cooling and tools — with smart features and built-in redundancy for peace of mind.

With 12kW of inverter capacity, it provides similar power to what most grid-connected homes receive, making it ideal for average households with 2–3 occupants. When no solar is available, maximum power from the battery alone is limited to 8kW total. Max battery discharge power of 4kW per battery. We recommend adding a 12–15kVA auto-start generator (diesel, petrol or inverter-compatible) to support backup charging, which is quoted separately.

Indicative fully installed after solar and battery rebate is $22,000–$30,000

Target Property Profile

Energy Independence Optimision

Average Households with 2–3 Occupants, Full-time Rural Property Owners, Homeowners Seeking Built-in Redundancy, Regional Homes Running High-Load Appliances

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.
