The Omaha 4-Bedroom Off-Grid Solar System suits a mid-large family holiday house with above-average energy needs.  Who uses gas for cooking, hot-water and ideally wood or gas fire in the winter. This System will enable you to run all the usual household appliances.  It even offers the capacity to run several kitchen appliances at once whilst still doing the vacuuming and a load of washing!

This System is designed for situations where daily power usage does not exceed 13-16kWh.

We highly recommend increasing your days’ autonomy from one day’s reserve to cover those dull stormy days. We can add more panels to your System and upgrade the battery bank (see Popular Upgrades).

Every Kitset includes a free consultation with a Solar Engineer, this call can be used to help with selecting the kitset/Customisation or advice with respect to installation and certification.

Tell Me More:

The Omaha 4 Bedroom Off-Grid Solar PV System is the ideal System for people expecting to use an average of 13-16kWh/day and where the amount of load required is 8kVA continuous (30min) and up to 21kVA 5sec peak (values at 25°C).   It comes with a 9.1kW solar array and a 17.76kWh battery bank.

At the heart of this Off-Grid System is the inverter/charger that provides a central unit to monitor and control all aspects of the System.  We also include conduits, cables and miscellaneous items for the System that comply with AS/NZ Standards (refer to our website for details).  This System is supplied with an outdoor battery cabinet so the battery bank can be installed outdoors.  The remainder of the equipment is best suited for indoor installations, which can be supplied prewired on an installation panel upon request.  AA Solar customise Solar Kitsets to suit your specific power needs and location.

How Much Power Will I have?

Your System has twenty panels; the 9.1kW solar arrays’ average daily power production will be between 15-19kWh in winter and up to 33-41kWh in summer.

Pro Tip: For year-round living, we highly recommend adding an auto-start generator. Provide backup power during periods when the weather is bad and your total solar generation is not enough to cover your energy needs and keep your battery bank full.

What Can Be Powered:

This System will power all the power requirements of a typical energy-conscious home with gas cooking and hot water and up to 8kVA peak demand for 30min.

  • Lighting°
  • Water pump°
  • Medium-large fridge/freezer°
  • TV°
  • Rangehood°
  • Macerator°
  • Internet, laptops, phone chargers
  • Suitable washing machine°
  • All small appliances such as jug, toaster, microwave create variable loads; please discuss planned usage with your trusted AA Solar Engineer. The key is to ensure they are not all used at once. Keep in mind that you have a total of 7kVA continuous, 8kVA for 30mins, and 21kVA for 5sec (values at 25°C) available.

This System can not support high wattage equipment such as electric induction cooking and ovens.

Note: AC loads must stay within the inverter’s limitations.

*We will provide a detailed estimate tailored for your specific needs; prices are an indication. They are subject to change due to customisation, shipping, or supplier price changes.  All PV generation figures are Auckland based, with PV modules facing True-North pitch without shading.  No system installation, inspection, commissioning, and maintenance allowance in this kit price.  Installations shall be in accordance with NZ law, regulations and associated standards.  Systems are wired to the main distribution board.  It is highly recommended that any system with less than four days of autonomy have an auto-start generator installed.


^ For Off-Grid PV Systems, the way you use power throughout the year and over a 24hr period will alter the system performance.  Normalised profiles have been used to provide kitset examples.
