Summary

100up's compact backup off-grid solar: 1.4kW solar (3 panels), 5 or 8kWh Sigenergy battery, 5-6kW Sigenergy inverter, mounted on a galvanised steel frame. Easy to deploy as a backup or tiny-house solution. 2,500-13,500.

Target Profile

Ideal for tiny house owners needing a reliable primary power source, small off grid dwellings where roof mounting is not practical, and hands on owner builders who want to complete most of the installation themselves. It’s also well suited to properties where the system may need to be relocated in the future, or for buyers who prefer to start with a manageable system and expand capacity over time.

The Small Compact system is 100UP’s ground-mounted off-grid kit built specifically for tiny houses and small off-grid dwellings. Free-standing, prewired, and designed to go up without heavy machinery. Two people can assemble the frame. An electrician needs an hour or two for the final connections, that’s it.

It runs on 1.4kW of solar and either a 5kWh or 8kWh Sigenergy battery bank. Enough for lighting, fridge, device charging, and small appliances. And if your needs grow, it expands. Also includes a switchboard and bracket system. This allows you to mount the switchboard and battery on the frame. Extra panels via 3-panel extension blocks, extra batteries whenever you’re ready.

The frame is portable too so it can relocate if your tiny house moves. Permanently installed or picked up and shifted. The system works as a Small Backup Off-Grid Solar System too .

  • System $12,500–$13,500
  • 3 Panels extension block $2,500–$3,000

OccupanCY Target
2.5 kW to 4kW
Daily Demand 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.
