Perth Solar Direct, Wangara
Solar battery storage Perth homes can rely on
Solar battery storage Perth Solar Direct designs, installs and supports. Store the solar you make during the day and use it after dark, with backup if you want it. We design, install and support the system.
Is solar battery storage Perth worth it for your home?
A solar system makes most of its power in the middle of the day. Most Perth homes use most of their power in the evening. A battery closes that gap. The WA Residential Battery Scheme and the federal discount now take a large share off solar battery storage Perth prices.
Use more of your own solar
Without a battery, daytime solar you do not use is exported to the grid. With one, it is stored and used at night instead of buying power back from your retailer.
Cover the evening peak
Cooking, air conditioning, hot water and screens all run after the sun goes down. A well sized battery carries the house through that period on stored solar.
Backup in a blackout
A battery paired with a suitable hybrid inverter can disconnect from the grid and keep selected circuits running. Not every battery does this, so tell us if backup matters to you.
Feed-in tariffs are low
The tariff you are paid for exported solar is a lot less than the price you pay to buy power in the evening. Using your own stored energy is worth more than selling it.
Whether the numbers stack up depends on how much you use, when you use it, the size of your solar and your tariff. Send us a recent bill and Perth Solar Direct will tell you plainly whether a battery makes sense for your home.
What affects the price
Every quote we write comes down to five things. Knowing them before you call makes the conversation quicker.
-
1
Battery size
Measured in kilowatt hours (kWh). A typical home uses somewhere between 15 and 30 kWh a day, but what matters is how much of that happens after dark. Bigger stores more and costs more.
-
2
Hybrid or AC-coupled
A hybrid inverter runs the panels and the battery from one unit. An AC-coupled battery brings its own inverter and sits alongside the solar you already have. Both work; the right one depends on what is on your wall today.
-
3
Your existing inverter
If your current inverter is battery ready it may stay. If it is not, we either replace it with a hybrid or AC-couple the battery to it. Its age and brand change the answer.
-
4
Single or three phase
Three phase homes need a three phase inverter or extra hardware if you want backup across the whole house. Single phase is simpler. Your switchboard tells us which you have.
-
5
Backup circuits
Backing up a few essential circuits (fridge, lights, a few power points) is straightforward. Whole home backup needs more battery capacity and more switchboard work.
Send a photo of your switchboard and inverter with your enquiry and we can price it faster.

You may have several questions about solar battery installation. Here are some common queries we encounter.
The lifespan of a solar battery can vary depending on the type, usage, and maintenance. On average, you can expect most solar batteries to last between 5 to 15 years.
Yes, one of the advantages of using energy storage units like these is their ability to supply backup power during blackouts. However, the duration and extent of this backup power depend on factors such as the size of your energy storage unit, its storage and battery capacity itself, and your household's energy consumption.
Under normal operation, the energy-generating equipment installed on your roof produces electricity whenever there is sunlight. This power is used instantly by your household, fed back to the electricity grid if it exceeds your needs, or stored in your home batteries or energy storage unit for later use.
In case of a blackout, an energy storage system paired with an appropriately sized hybrid inverter can disconnect from the grid and establish a 'microgrid', or virtual power plant, allowing your home to function independently from the main electricity network. This process is commonly referred to as 'islanding'.
The power reserved in the storage unit can then be utilized to supply electricity to your household, providing backup power until the grid power is reinstated or the storage unit is drained. The energy-generating equipment may continue to charge the storage battery inverter unit during daylight hours, thereby extending the duration of the backup power.
It's important to clarify that not all energy storage units can provide backup power during a blackout. Some energy storage systems, particularly older models or budget-friendly options, might lack this feature. At Perth Solar Direct, we're here to provide advice on the best energy solutions to meet your specific needs, including offering backup power capabilities.
For residences that encounter frequent or extended blackouts, having an energy storage unit that can deliver reliable backup power can be transformative. It's one of the multiple benefits of integrating energy storage with your energy-generating system, granting energy independence and peace of mind.
Regular maintenance and servicing, like what we offer at Perth Solar Direct, can ensure your solar battery performs optimally. This includes checking the connections, monitoring performance, and keeping the system clean.
Solar battery installation should be carried out by a professional to ensure safety and optimal performance. Incorrect installation can damage the battery and potentially void the warranty.
Determining the perfect size for your solar energy storage unit is crucial in maximizing the benefits usable capacity of your solar energy system. The appropriate size depends on several factors, including your energy consumption patterns, the capacity of your solar energy system, and how much energy you want to reserve for later use.
The first factor, your energy consumption, can be determined by analyzing your electricity bills over a year. This will provide a good understanding of your average daily electricity usage. For a residential home, this electricity bill usually falls between 15 to 30 kilowatt-hours (kWh) per day, but it can be significantly higher for businesses.
The second factor to consider is the size of your solar energy system. If you have a large system that produces a lot of energy, you may need a bigger storage unit to store excess power.
Alternatively, if your system is smaller and you still want to be largely energy independent, you may also require a larger storage unit to store energy for use when your system isn't producing enough power, such as during cloudy days or at night.
The third factor is how much energy you want to store for later use. This depends on your goals. If you want to maximize self-consumption and minimize reliance on the grid, you might need a larger storage unit. However, if your main goal is to have a backup energy source for power outages, a smaller unit may suffice.
In the initial consultation with Perth Solar Direct, our experienced consultants can help determine the ideal size for your solar energy storage unit. We analyze your energy consumption patterns, the size and productivity of your solar energy system, your goals, and your budget to recommend a storage unit that will meet your needs and provide the maximum return on investment. Every home or business is unique, and our approach is to provide a customized solution that fits your specific requirements.
