360 degree energy savings, backup/ Emergency Power Supply (EPS), off-grid. Your primary purpose will often define your ideal solar battery selection. Compare solar batteries below and understand the differences from AC coupled to DC Coupled solutions.
What do you need?
It can be a little tricky selecting the right battery type for one’s unique circumstance. Therefore, let’s make things a little easier by narrowing down the three main categories.
All-in-one
No solar inverter required. Manages both solar & battery sources.
AC-coupled
Ideal as a retrofit or combined to any standard solar inverter.
DC-coupled
Ideal as a retrofit or combined to any standard solar inverter.

If you thought selecting the ideal solar panels is a confusing process, welcome to the world of ideal battery selection.
Nonetheless, your friendly team at PSW have your solar battery questions answered!
Is there a battery rebate in WA?
No.
Available subsidies for Perth & Bunbury region WA exist only around carbon offset emissions on generation capacity, such as the solar array size.
Combining solar with batteries as a whole will allow subsidising of the entire package, but no more than if solar is installed without the battery.
Can I install a larger battery capacity over solar panel rating?
Yes.
This is because basic system sizes in solar vs battery are completely different.
Solar PV systems are advertised as kW. This is the amount of peak power the combined system can produce as a whole at Standard Test Conditions.
Battery systems are sized by kWh. Is is a more accurate reflection of supply ability over time. The peak power of a battery is often determined by the inverter it is connected to.
Will I still receive DEBS if I add a battery?
Quite Likely.
If you qualify for the Distributed Energy Buyback Scheme (DEBS) you can receive 0.03c off-Peak and 0.10c Peak for each unit (kWh) exported by your solar energy system.
As long as the battery is set to zero export and the solar inverter capacity isn't being increased, it's quite likely (subject to Synergy approval) you'll still qualify for DEBS.

Can I add batteries to an existing solar system?
Yes.
It's all about battery selection. Potentially the easiest battery to to add to an existing standard solar energy is referred to as AC coupled in the variants such as the Tesla PowerWall 2 and the SENEC.Home range.
Alternative DC coupled battery options are available for standard string inverters in the form of the SolarWatt Matrix range.
How much do batteries cost?
It all depends on what you want the solar battery to do. If you are looking at storing solar energy for later use with no back-up functionality, this is the most affordable option.
Want to capitalise on a solar batteries back-up features? Expect to pay more for the luxury as individual installation specifics will always play a big part. There is no average here.
The mother of all, off-grid. A well thought out energy assessment and a sizeable investment is required when compared against any advertised prices or basic battery system. Battery deals >
What is the best battery for 3-phase power supplies?
3-phase power supplies are a little tricky.
To keep it simple single-phase battery systems can work with 3-phase power while still proving energy savings across all 3-phases thanks to net metering here in Western Australia. However, if requiring back-up power supply features in the event of a blackout, only 1-phase can be supported - Powerwall does this brilliantly.
If requiring all three-phases to be supported in the event of a blackout, the best battery options are potentially DC-Coupled batteries as their output is governed by the connected inverter.
An excellent inverter option which facilitates 3-phase back-up power is the Goodwe ET range. Perhaps what distinguishes this particular inverter even more than alternative three-phase hybrid inverter offerings is the ability to supply the back-up loads as an uninterrupted power supply (UPS) - the pinnacle of back-up functionality.
The Soluna 15k and the BYD HVM DC-Coupled solar batteries are two battery options within the PSW range which couple perfectly with the Goodwe ET 3-phase hybrid solar and battery inverter.
The Huawei LUNA battery, compatable with the Huawei M1 three-phase hybrid inverter is another great three phase option at minimal expense. However, back-up features are limited, requiring an additional back-up box as opposed to an all-in-one solution (specifications yet to be released).
Can I view a working battery system before buying?
Yes.
Almost all battery brands are available for viewing at the PSW Research Centre. It's advised to always check prior to arrival though due to stock rotations.
