How does a Solar battery actually work?
Your switchboard is connected to the solar panels via the inverter, powering your home first and foremost. If your solar is generating more than what your home needs an excess, the switchboard will then direct that excess into the solar battery.
A solar battery effectively allows you to store some of your free energy instead of sending it all to the grid. This allows you to use that energy at night and other times of low generation, helping you import less from the grid and lowering your bills!

Why add a battery to my solar system?
Peak solar production happens during the day between 10am and 4pm, which is when most of your appliances should be run. However, a large chunk of electricity consumption happens at night, when the sun isnt shining and solar isnt generating any energy.
To top it all off, feed-in tariffs in Australia can be as little as 5c/kWh. What this means is you are essentially sending your solar power to the grid during the day, only to buy it back for way more than that at peak rates.
The addition of a solar battery to your home will help you:
- Maximise the use of your solar energy even when the sun is not out (like at night).
- Reduce your electricity bills by decreasing your energy consumption from the grid.
- Add an extra layer of monitoring to your solar setup via Energy Management Software.
- Future proof your home against rising energy costs.
- Option to keep your home powered through brownouts and blackouts.
How much will a Solar battery cost me?
There are many important price factors when calculating the total cost of a fully installed solar battery:
- Battery size
- Voltage
- Quality
- Battery technology
- Grid or off grid
- Brand
- Backup enabled
- Variation in installation
Enjoying the benefits of a solar battery has never been more affordable, easier or more accessible than now. At Soltech Solutions, we can offer a fully installed solar battery at a great price. Contact us today for a no-obligation quotation.
Are there any Government rebates or incentives when installing a solar battery?
Currently only some states and territories in Australia offer rebates and subsidies to help in the purchase of a solar battery.
These include the ACT, VIC and SA.
What size Solar battery do I need?
Your electricity bill can help you find the average daily electricity usage for your household in 24-hour periods. Most of us use lots of energy early in the morning before work and school and in the evening when everyone has returned home. These times are when your solar panels are generally producing the least amount of electricity. Picking the correct battery size becomes a critical aspect of your required solar storage.
It is vital that you talk to us first so we can review your electricity bill and understand your homes energy needs. Only then can we calculate and design a system that will be the right solution for you and your homes needs.
Do you install Solar Panels?
No, we do not install Solar panels. We specifically specialise in the supply and installation of solar batteries. This sole focus has allowed us to become leaders in our industry and provide you with the best possible service.
We will be happy, however, to refer you to one of our many trusted partners who specialise in supply and install of solar panels.
Can solar batteries be installed indoors?
Some models can be installed indoors, however, it is more common and highly recommended to have them installed close to the switchboard for ease of installation and safety purposes. At Soltech Solutions we abide by government and industry standard regulations when choosing a place to install your battery.
Can we add more storage to our battery system in the future?
Yes, it is possible to increase the capacity of a battery system with modular architecture. This means that you can add storage sub units to the main battery which will increase how much energy you can store. Please be aware that not all batteries models are modular. Please discuss with us upfront if you would like this option and we will select the most suitable model for your system.
How long will my battery system last?
Solar battery manufacturers test their products under standard conditions in what is called a cycle or in simple terms one full charge and discharge. Different battery models have different specifications, so it is a good idea to check the technical sheets for the brands and models youre interested in to get information on their life cycle.
We do offer extended warranties for purchase if you would like an extra level of coverage for your investment.
Do all solar batteries include ‘Blackout’ protection?
No. If blackout protection is important to you, please advise us upfront and we will select a model that offers a UPS backup mode. There will be extra costs associated with upgrading your switchboard and wiring the circuits to be backed up.
What is UPS?
UPS stands for Uninterruptible Power Supply, or in other words, blackout protection.
What is DoD?
DoD stands for Depth of Discharge. The DoD is shown as a percentage, indicating the maximum amount of energy that can be consistently used from the storage. This is because most batteries require to hold some charge to avoid accelerated battery degradation. Therefore, a battery with a DoD of 95% should not be discharged under 5% of its capacity on a regular basis.
What is EMS?
EMS stands for Energy Management Software. Many modern solar batteries models provide some kind of online monitoring tool in the shape of an App or web portals that allows you to control the battery, check its status, gauge solar generation and measure energy consumption. All EMS’s are unique to the brand and model you purchase, so ask us for the specifics when we design your battery system.
