Utilising our network of trusted suppliers from across Australia (and abroad where an equivalent quality product is not available domestically), Statewide Power has created the perfect scalable package with options to meet the off-grid energy requirements of any small household.
We’re committed to quality – if we wouldn’t use it ourselves, we won’t recommend it to you. The Sigenergy Extra Small Off-Grid Solar System makes getting started easy by providing everything you need, with options for both basic and premium packages to best suit your home and energy consumption.

Included Components & Quality Assurance:
- Solar Panels: We use WINAICO solar panels. Their 30-year product & performance warranty (triple the industry standard) offers unbeatable peace of mind.

- Battery Cabinet: PowerPlus Energy Slimline are weatherproof, modular cabinets designed and manufactured right here in Australia.

Installation Includes:
- Roof or ground mounting (ground mount incurs approx. $1/watt + footing costs).
- Testing, commissioning, and regulatory approvals.
Optional Cost Adjustments:
- Deduct $9,000 – $12,000 if you supply your own generator or connect to the grid.
- Upgrade to a DEUTZ premium generator: Add $2,000 – $4,000 (depending on size).
- Systems are modular and scalable: Add or remove batteries or panels as required.
Custom-designed solutions are available for remote resorts, industrial sites, and large-scale applications. - Packages for three-phase electricity are also available.
Long-Life Battery Upgrade Option:
For an ultra-long-lasting, premium battery option, consider Zenaji Aeon Lithium Titanate Batteries:
- 20-year warranty.
- 22,000 cycle lifespan.
- Costs more upfront but they offer double the life of LiFePO4 batteries and deliver the lowest cost per kWh/lifecycle on the market – ideal for long-term savings.
Pro Tips – Some Things to Consider When Buying an Off-grid System:
- Oversize your solar panels: Cheap to add, and helps meet summer and winter loads more easily.
- Right-size your batteries: Avoid undersizing to protect lifespan and reduce reliance on generators.
- Future-proof your system: You can easily add more batteries later as your energy use grows. Remote programming available.
- Plan for future demand: Consider upsizing your inverter now if you expect to add a pool, EV charger, or large aircon later.
