Battery Systems

Start storing your energy

STOP selling your power back to the grid for $0.07 and start storing that energy. Battery solutions are becoming more affordable by the day and Solaire Connect continues to help customers save thousands of dollars along the way. Companies have pushed and driven the market with cheap alternatives but these products will fail over time and cost customers thousands in service and repair work. Solaire Connect has again aligned themselves with quality manufacturers and suppliers who will stand the test of time and provide customers with efficient and long lasting energy solutions.

Solaire Connect’s portfolio of battery installers is growing by the week which in turn is minimising our customers’ dependency on the grid. Solar Power is a long term investment, so minimise any potential headaches and meet with one of our consultants today to discuss your battery requirements.

Frequently Asked Questions

How do Solar Batteries work?
Solar batteries work by storing any unused energy you may generate from your solar system, for you to use when solar isn’t available e.g. night time or overcast days.
- Sunlight comes through your solar panels.
- Your inverter converts this energy to AC power, which gets used directly by any appliances or items you might have going during the day.
- The extra power created by the solar panels, which otherwise gets fed to the grid, is used to charge your battery.
- If your battery is fully charged during sunlight hours and you are still generating power, this will be exported back to the grid.
Are Solar Batteries worth it?
Solar batteries can definitely be a worthwhile investment, particularly if your home has a large solar set up that can’t make use of Synergy’s feed in tariff (over 5kW in size). Battery prices have dropped significantly over the past few years and are fast becoming a household staple for homes utilising solar. The payback period will vary across different households but will, of course, be more than if you opted for solar alone, so consider your personal situation before deciding if a home battery unit is right for you. Batteries are great however, at eliminating power bill shocks and saving you money during your peak energy usage periods, like summertime.
How long will my battery last?
If looked after well, a Sodium Nickel Chloride battery should last you approximately 18-20, ending its life with around 60% efficiency. The Sodium Nickel Chloride batteries we stock are BYD and Sungrow.
Similarly, a Lithium-ion battery (Sonnen and Huawei) should last you 15-20 years. Efficiency drops to 80% around the 10-year mark and at 15-20 years it may have dropped to 60% also.
All of the battery brands we stock at Solaire have a 10-year warranty period.
Can I use my battery during a power outage?
Many solar batteries offer a ‘blackout mode’, letting them kick in automatically when a power outage occurs as long as they have enough stored energy. They help to send power to your most essential appliances, like your fridge and freezer.
How many appliances can I run during a power outage?
This is all dependent on what your inverter capability is. On the spec sheets you will see there is a section that specifies ‘Output (Back up Power or Backup)’. Within this section it will give you a maximum rating of amps for the inverter in back up mode and if your load is under this, then the inverter should be able to run the appliance. Typically, Solaire will back up the fridge, TV and light circuit.
Will my battery give me a zero power bill?
Not necessarily. While connected to the grid you will always have a service/connection fee. As for power usage, if you are strategic with your consumption you can make a huge dent into your power consumption, with some of our customers reducing their overall consumption by 90%.
