Tell Me More:

This Waihi Studio Off-Grid Solar PV System is ideal for people expecting to use an average of 3-5kWh/day and where the amount of load required is 2.4kVA continuous and up to 4.8kVA 5sec peak (values at 25°C).  It comes with a 2.73kW Solar Array and a 14.4KWh (7.2kWh usable) 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. 

AA Solar customise Solar Kitsets to suit your specific power needs and location.

How Much Power Will I have?

Your System has six panels; the 2.73kW solar arrays’ average daily power production will be between 4-6kWh in winter and up to 9-12kWh in summer.

Pro Tip: For year-round living, we highly recommend adding an auto-start generator. To 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 can meet all the power requirements of a typical tiny home with gas cooking and hot water, provided that the total power draw at any one time does not exceed 2.4kVA continuous.

  • Up to 10 LED Lights
  • Small under bench or Dometic Fridge
  • TV with power rating less than 400W (LED/LCD up to 40″)
  • And all small appliances such as jug, toaster, and microwave as long as they have a maximum power rating under 1,000W; should be used one at a time.
  • Small washing machine on a cold wash

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 to 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.

Popular Upgrades

All systems can be tailored to your individual needs by our highly qualified solar engineers.  Our most common upgrade provides backup power for low light days.

We can also lift the available power with a Lithium Battery/Inverter Package, which delivers more power while taking up less space.
