How to choose an off-grid solar package for your 4-bedroom home

This is the general rule of thumb we follow for recommending our systems:

But it is not a one-size-fits-all approach, there could be other factors in your lifestyle or location that will impact what you need. We recommend watching this video/article to get a better understanding. 

Case study
Here we have an example of one of our customers. They have a 4-bedroom home with a family of 2 adults and 3 children. This is an estimation of their daily power consumption:

Based on this family's required energy needs the calculator has matched them with our Tui Solar Nest and The Lifestyle Pro. Both of these packages will generate enough daily power to keep this family going, as well as allow for a decent amount of head room for safety even in the winter months. 

After discussion with the GridFree team this family chose to size up one more bracket to The Retreat Pro because they tend to have a lot of visitors - so they wanted to ensure they'll have enough power when they've got extras staying. 

Your results may vary if you are more on the conservative side of your power consumption or if you are rather power hungry. We recommend filling out the Solar Calculator to see what your total average daily generator number will be.

If you’re in a similar situation as the example above, we recommend:

• The Tui Solar Nest with 3 batteries – for a more power conservative approach.
• The Tui Solar Nest with 4 Batteries – to sit comfortably.
• The Retreat Pro – for higher power, without constant monitoring.

Extra things to consider:

• Swap your cooking and water heating to alternatives like gas or wood fire. 
• Have a back-up generator.
