Medium Off-Grid Solar System – More Power, Built-in Backup

This system is ideal for medium homes, small farms, or full-time off-grid living. With dual inverters and a larger solar array, it’s designed for higher energy use and added peace of mind — if one system goes down, the other keeps things running.

  • Solar panels: 6kW to 20kW system size, depending on your usage, roof space, and energy goals. Sigenergy inverters allow solar input up to double their output capacity, meaning we can oversize your solar to maximise generation throughout the day — especially useful in winter or on cloudy days.
  • Inverter: Two 6kW Sigenergy off-grid inverters (12kW total capacity, 10-year warranty)
  • Battery: 16kWh usable Sigenergy battery (expandable, 10-year warranty)
  • Monitoring: Online access to system performance and battery levels
  • Backup generator: 8kVA or larger recommended

💰 Installed cost (after rebate): $22,000–$30,000
