Custom Off-Grid Solar Systems – Tailored Power, Built Your Way

Need something outside the box? We design fully custom off-grid systems for homes, farms, and commercial properties with larger or more complex energy needs. With scalable inverters and battery banks, we’ll build a system that matches your usage — with room to grow.

  • Solar panels: System sizes available from small setups right up to 100kW, which is the current limit for STC rebates under the Small-scale Renewable Energy Scheme. Systems over 100kW fall under the LGC (Large-scale Generation Certificate) program — which has different rules and rebate structure. We can design systems under either scheme depending on your goals.
  • Inverter: Sigenergy inverters from 6kW to 12kW each, installed in parallel — no fixed limit on how many. We scale total inverter capacity to match your required load.
  • Battery: Each inverter supports 1 to 6 x 8kWh Sigenergy batteries (up to 48kWh per unit). Total storage can be sized to suit your property’s needs.
  • Monitoring: Full remote access to system performance, load, and battery status
  • Generator: Recommended size varies — we’ll advise based on your total load and expected runtime

Quoted based on property inspection, usage profile, and system size.

This is the best option for large off-grid homes, commercial workshops, or mixed-use properties where standard packages just won’t cut it.
