  • Our systems are tailored to meet your specific needs
  • Costs of systems vary depending on your exact circumstances and requirements
  • Chat with one of our friendly team and let them help you find the right solution
  • Most standard family homes will need a system in the $30,000 to $45,000 range, but this entirely depends on what needs powering
  • *System prices that are shown have been provided to you as a guide only, and are starting prices that assume standard installation with all necessary OEA specified infrastructure and site preparations taken account of by the customer.

    Further Cost Considerations:

  • Rebates:
  • Federal government rebates exist for eligible applicants, ranging from $1,700 – $30,000 depending on how much renewable energy is included in the final system

  • Renewable Energy Fraction:
  • The less renewable energy included in the system design, then there will be more ongoing generator costs

  • Equipment Placement:
  • For sites that do not have a suitable enclosure to house our AdaptUnit then the EnergyBox might be required.

  • Grid Connection vs. Off-Grid Power:
  • Determining the cost to connect your house to the electricity grid is an important first step when trying to consider whether to live on or off-grid.

    Off-Grid Systems

    Off-grid power systems supply electricity to properties that are not connected to the public electricity network. These systems are often referred to as “stand-alone power systems” (SAPS).

    The Off-Grid Energy New Zealand Advantage

    Off-Grid Energy New Zealand systems have market-leading life expectancies, and begin with superior design. This is achieved through the following fundamentals:
    Quality Only
    It’s not wise to make compromises when you are energy independent. There is a world of difference in the quality of system components, so we ensure to only source the very best.
    Expert engineering and design
    Common issues with inferior off grid systems include poor sizing, mismatched equipment, non-compliant design, and unsafe installation – resulting in frustratingly insufficient or unreliable power, and a costly short system life. Our expert technicians will spend time with you to ensure these pitfalls are avoided.
    AC coupling
    Compared to other technologies, this type of system configuration increases efficiency, flexibility, and lengthens battery life.
    Advanced Battery Management Technology
    Our battery management systems are unparalleled. Many other battery storage systems have simplistic and crude battery health monitoring, resulting in a compromised system life. Our battery inverter systems ensure the batteries receive the right attention at the right time with pinpoint accuracy. Best of all, this complex hard work happens automatically.
