Why use Solar Battery Storage?


With a solar battery storage system, either hybrid or off-grid, you can save the energy you generate to use later when the sun isn’t shining. There are several other advantages of solar battery systems:

  • With NZ feed-in grid tariffs dropping significantly and grid prices continuing to rise, there’s an incentive to use more of the power you generate. Why feed energy to and from the grid at an unfavourable rate when you can store it to use later?
  • The price and efficiency of solar battery systems is better than ever. Traditional deep cycle lead-acid batteries are being replaced with more efficient and longer lasting lithium-ion (Li-ion) batteries.
  • You can use battery storage to avoid power black-outs. Unlike a grid-tied solar system which automatically switches off, a battery storage system allows you to keep generating and consuming energy when the grid goes down.



See below for our range of hybrid solar batteries, or see our off-grid batteries here.


Why use a Lithium-ion Battery?



CPS Solar recommends Li-ion batteries. They have a number of advantages over lead-acid batteries. They are:

  • Smaller and lighter, meaning they require less space in your home
  • Able to be recharged faster
  • Able to be deeply discharged, up to 90% of total capacity, without compromising the life of the battery
  • Less likely to degrade during charging and discharging, so have a longer life
  • Pre-wired, reducing installation costs
  • Able to be safely stored inside without the need for venting systems as they do not expel volatile gases.

Triple Power Solar Battery


Designed and manufactured in partnership with SolaX, the Triple Power Lithium-ion Battery is a new high-voltage solar battery solution.

Triple Power batteries are available in 4.5kWh and 6.3kwh modules that can be installed in a series (up to 4 batteries of the same size) to the master box, allowing for a highly flexible and powerful energy storage solution.

For optimal functionality you can download the Solax Cloud app onto your smart device to monitor energy levels, temperature of the appliance and choose which devices are powered by the energy.

Choosing the Correct Battery Size

It’s very important to configure your system correctly, including choosing a compatible solar inverter. The team at CPS Solar are experts in assessing your requirements and budget constraints, and we undertake a free comprehensive on-site consultation before we recommend the optimal solar solution.

As a general guide, these are approximations for solar system and battery storage sizing:

  • Low Energy Household
    1-3 people using 10-15kWh/day
    Recommended solar system: 3kW plus 4-6kWh battery storage
  • Average Energy Household
    3-5 people using 15-25kWh/day
    Recommended solar system: 5kW plus 8-12kWh battery storage
  • High Energy Household
    4+ people using 25+kWh/day
    Recommended solar system: 5-8kW plus 14-20kWh battery storage
