Battery Storage

Increase your independence from the grid and store energy from your solar panels.

Battery storage is the perfect addition to your solar system. Take advantage of Wanaka’s abundant sunshine by storing excess solar energy produced during the day for use at night. In addition to making the most of your solar, installing batteries also protects you from power cuts. 

Most of the batteries we install are grid-tied but we are also experts in designing and installing off-grid systems in the Wanaka area. With Wanaka Solar, you can trust that you’ll receive a solar battery system to meet all your needs, whether you wish to go off-grid or not.

Why include a battery?

By including a battery in your solar system, you unlock two major benefits: increased independence and protection from grid outages.

Save Money and be independent

By storing your solar you reduce your reliance on the grid. This helps you save even more money on electricity bills. During the summer months, some customers are able to be effectively off-grid for 24 hours a day!

Protected from grid outages

Wanaka’s grid can be unreliable at times. But with a battery, you’re shielded from power cuts. While your neighbours’ lights go out, yours will stay on. Enjoy uninterrupted power and peace of mind.

Off Grid or Grid-tied

When it comes to battery storage, Wanaka residents have two options to consider: off-grid or grid-tied systems. Here’s what you need to know:


Off-grid systems offer complete energy independence for those who want to go the extra mile. The size of the solar system, battery bank and unfortunately budget will likely increase from a grid-tied system unless you are a very low energy user. Get in touch with our experienced team to help design a customized off-grid system to meet your specific needs.


You can add a battery to your solar system while remaining connected to the grid. This is called a hybrid or grid-tied solar system. It allows you to store solar energy produced during the day to be used at night. It also protects you from power cuts as you have a backup power source when the grid goes down. But you are still connected to the grid when you need it. For most customers, a grid-tied system is the optimal approach.
