With a new low adoption cost after the available rebates, home batteries have become a viable Synergy bill relief solution even without solar panels. Added features, such as blackout protection options, are a bonus. Perth Solar Warehouse is your locally proven home battery provider with a modern twist.
Perth’s best solar battery deals. Here’s quick access to our latest catalogue ›
Influencing your ideal solar battery: (1) Storage capacity, (2) Blackout protection, (3) Solar generation, and (4) Energy management features. Refine your ideal choice through two primary categories: AC or DC-coupled batteries.
AC Coupled Batteries
Perth Solar Warehouse provides three leading AC-coupled batteries ideal for diverse power supplies and existing solar energy systems on the Western Power network.
Reviews:
We’ve compiled in-depth buying guides for these leading brands: Tesla, Franklin WH (coming), and Alpha ESS. Sigenergy is also available as an AC-coupled battery, and due to its topography, the Sigenstor system is available in our DC-coupled battery section (further below).
1) You have an existing solar energy system, or
2) You your rooftop can’t accomodate solar but want to leverage the energy independence a home battery system delivers, including blackout protection, enhanced energy profile visualisation, and improved energy savings by shifting away from the Synergy Home Plan A1 tariff.
3) Supply chain and the global competitiveness lithium cell technology affects a relative energy density value among options. Feature sets, brand bankability, broader ecosystems and software superiority more often differentiate product options.
AC-coupled batteries offer more expansive features that may improve overall value ahead of comparing energy density, cost-per-kWh, alone.
Always be aware a systems feature set vs your expectations when comparing AC and DC coupled batteries.
DC Coupled Batteries
Perth Solar Warehouse provides six leading DC-coupled batteries ideal for popular hybrid solar inverter brands connected to the Western Power/Synergy energy network.
Reviews:
We’ve generated in-depth buying guides for all leading DC-Coupled battery brands: Sigenergy, Sungrow, BYD, Goodwe, Growatt, and iStore.
You have an existing solar energy system with a compatible hybrid solar and battery inverter that you would like to add simplified storage capacity to.
OR, you are installing a new solar energy system and want to increase solar capacity above STC and grid limitations [Note: selected AC-coupled batteries are now also approved achieve a similar oversizing loophole].
The most significant appeal of DC-coupled batteries is the cost-per-kWh when increasing energy density. This improved storage affordability comes at the expense of reduced features.
Due to the scaled back nature, DC coupled solar batteries by Perth Solar Warehouse provide the best value cost-per-kWh for energy storage. However, this is often balanced out when considering additional hardware in hybrid inverter costs and blackout protection features if required.

Three potential avenues exist for solar battery rebates in 2025. Their current status of availability in Western Australia is as follows:
- Federal (Government): July, 1, 2025.
- State (Government): July 1, 2025.
- Manufacturer (non Government): n/a.
Given the variability of solar battery rebates, we’ve developed a central post reflecting the different solar battery rebate options available in Western Australia.
Quite Likely. If you qualify for the Distributed Energy Buyback Scheme (DEBS), you can receive 2c off-peak and 10c peak for each unit (kWh) exported to the grid by your solar energy system.
As long as the battery is set to zero export and the solar inverter capacity isn’t being increased, eligible customers should still qualify for DEBS (subject to Synergy approval).
Yes. Because advertised system sizes in solar vs battery are entirely different.
Solar energy systems are advertised in kW. Kilowatts (kW) is the maximum peak power the combined system can produce at Standard Test Conditions.
Battery systems are sized by kWh. Kilowatt-hours (kWh) more accurately reflect power over time (a battery’s storage capacity). The inverter to which a battery is connected determines its peak power.
For example: combining a 13.5 kWh Tesla Powerwall with a 6.6 kW solar system is entirely acceptable. Because the 6.6 kW solar energy system produces an average of 30 kWh per day (power over time), resulting in the ability to store almost half your average daily solar generation yield.
It depends on how you use your power. Most solar batteries come in different sizes, but they all have a limited capacity. You choose your investment based on your stored energy needs. Cheaper batteries often have a reduced useable storage capacity compared to more moderately priced batteries. Cost-per-kWh is a better way to normalise battery comparison costs: Cost ÷ useable kWh.
When the battery’s stored capacity (kWh) or maximum rated power output (kW), the energy consumed comes from other sources (solar or grid), and the battery becomes ineffective for its intended purpose.
Yes, hone in on AC-coupled batteries!
Battery options broaden slightly if you possess an existing hybrid inverter where nominated DC-coupled batteries may be available.
