BYD premium LVS batteries debuted in Australia in 2017. Although they’re still relatively new to the market, BYD’s Battery Boxes offer both high and low-voltage options that are compatible with inverters such as Sungrow, Fronius, and SMA.

Features

BYD solar batteries have a range of interesting features to keep customers happy, such as:

• Lithium iron phosphate (LFP) battery pack
• Stacked battery modules
• IP55 protection
• Extendable features
• Up to 96% round-trip efficiency
  
  

Specifications

Benefits

The upside to BYD batteries is most notably their size range. With stackable modules, you can easily add to your system if you need more storage in the future. With a good inverter, these batteries can store lots of power when needed. BYD’s wide inverter compatibility also means you don’t have to overhaul your entire system just to integrate a new battery. Compared to other batteries on the market, BYD is incredibly efficient, as seen by incorporating their stackable, modular concept.

Price

Because of the stackable nature of BYD batteries, your out-of-pocket costs depend primarily on how much storage you need. On the low end, we’re looking at around $2000 for batteries only, excluding installation and inverter costs. On the high end, it’s more like $15,000 if you purchase all the bells and whistles. Depending on your household needs, BYD could be an affordable option.

Drawbacks

There are a couple of drawbacks when it comes to BYD solar batteries. Since they’re only a few years into the Australian market, it’s still difficult to predict the long-term results of battery performance in our climate. Although there have been no notable issues to date, time will tell whether this battery can take the heat. Secondly, BYD has discontinued production for some of its older models. That means those with older systems might be limited if they need to expand to meet their energy needs later.

Specifications

Benefits

The main benefits of GoodWe Lynx Home U batteries is their reliability, low voltage modular system, and installation flexibility. The GoodWe brand has been in the Aussie solar market for a few years, building a reputation for its inverters. It provided a good foundation for introducing the Lynx Home U battery, with a modular system that allows users to add storage easily if their energy needs expand. The LFP battery is also one of the safest batteries on the market. 

Price

A GoodWe solar battery is a good deal for solar users on a budget. The smaller 5.4 kWh battery starts at around $3,500, excluding installation costs. Prices will differ depending on how much storage your household requires, but it’s generally an affordable option compared to other solar batteries. Note that energy storage needs for an off-grid system are usually much higher than for a grid-connected system. 

Drawbacks

As with all off-grid solar systems, opting for an off-grid battery means you won’t have the option of switching back to the grid if you run out of stored energy. Although the Lynx Home U series offers lots of storage, you’ll still need to be on top of your energy consumption, especially if your panels aren’t running efficiently. 

Best all-in-one battery energy storage system (BESS): Redback Smart Hybrid System

Image of Redback Smart Hybrid System

Solar + battery systems generally consist of a separate battery and inverter. The Redback Smart Hybrid model presents an all-in-one storage solution. If you’re not a fan of external cables, this battery energy storage system (BESS) is the way to go.

Features

The Redback Smart Hybrid System is full of exciting features like:

• User-friendly app and portal
• All-in-one design
• Expandable battery storage
• Pre-wired BoS 
• Optional expansion cabinet
• Blackout protection
  
  

Specifications

Benefits

The greatest benefit of a hybrid system is the all-in-one factor. Hybrid systems give you total power control while still being connected to the grid. You also get the benefit of being able to use your solar energy after dark and during blackouts. Many hybrid solar + battery systems allow you to continue to generate solar energy and use your stored energy in your home even when the grid is down. Hybrid systems are also very customisable. The Redback system in particular has an optional storage cabinet that takes your capacity up to 28.5 kWh.

Another upside to the Redback system is its user-friendly monitoring app. It keeps you connected to your system on the go. You can check out your energy usage and battery activity from the comfort of your own device. If you prefer your data on a larger screen, there’s also the Redback portal.

Price

The cost of your Redback Smart Hybrid System varies depending on product specifications. Since the system is so customisable, prices will fluctuate based on your storage capacity and system size. You’ll need a qualified installer who has experience installing hybrid systems. Complex installations can generate higher costs but if upfront costs aren’t your thing, don’t worry. Plico don’t believe in big upfront costs, and you can install your system for one low weekly instalment and have ongoing support for the length of your contract. Find out just how affordable a solar and battery system can be here. 

Drawbacks

The main drawback of a Redback Smart Hybrid System is its inability to go above 28 kWh. Having said that, this capacity is plenty for residential, so don’t let that put you off. For a larger system, the Redback is quite compact, and should be appropriate for any home. 

#3: Tesla Powerwall 2

The Tesla Powerwall 2 is one of the most popular solar batteries right now. Powerwall batteries are low-maintenance storage solutions that can withstand outages and keep your lights on when the main grid is on the fritz. These batteries have earned a positive reputation by delivering quality results to customers. They’ve also gained a reputation for being one of the most expensive solar batteries on the market. 

Features

Tesla solar batteries are known for having a variety of desirable features, such as:

• 90% round trip efficiency
• Monitoring app to track energy use
• Modern and compact design
• Flexible mounting options
• Backup protection 24/7 
• Rechargeable lithium-ion battery pack
  
  

Specifications

*The Powerwall 2 has a DoD of 100% according to Tesla. However, they also noted the discrepancy between nominal and usable capacity, which makes the DoD 96%. If you see a DoD above 90%, what you’re actually witnessing is good marketing. If a battery’s capacity is 14 kWh and its usable capacity is 13 kWh, companies can list the official capacity as 13kWh and boast a 100% DoD (because it’s ‘using’ all of its 13 kWh capacity).

Benefits

The Powerwall 2 has great performance metrics overall. Combined with the reputable Tesla name and 10-year warranty, customers receive a certain level of security with this battery. Since the Powerwall 2 uses liquid cooling, it’s more operational at a wider range of temperatures, which is advantageous in the Australian climate.

The design is sleek and luxurious. Even though it packs power, the Powerwall 2 is on the slimmer side of solar batteries and isn’t going to take up too much space wherever you choose to mount it.

Another highlight of this system is the app technology. With the Tesla Powerwall app, you can track your solar energy usage and control when you charge and discharge your battery. It also includes a feature that detects weather events that could cause blackouts and then prioritises charging to capacity so you have a backup if there’s an outage.

Price

The Powerwall 2 solar battery will set you back around $12,000, excluding installation costs. Installation prices can be anywhere from $2,000 - $3,500, depending on how complicated the process is. So, if you’ve got your heart set on a Powerwall battery, you’ll need to face the significant upfront costs.

Drawbacks

Although the Powerwall 2 looks appealing at first glance, there are a few drawbacks. Aside from the jaw-dropping price and dubious return on investment, Tesla battery customers don’t really get much choice in terms of size and feed-in type. The Powerwall 2 only works with single-phase power, and 12.5 kWh batteries are your only size option. Compared with expandable battery systems, it falls short. 

#2: Sungrow High Voltage LFP Battery

The Sungrow High Voltage LFP battery is known for its high performance, safety, and flexibility. Although Sungrow is better known for inverters, their batteries are also top-notch. It also comes in lots of different sizes to suit your home. 

Features

When you purchase a Sungrow solar battery, you can expect to enjoy features like: 

• Lithium iron phosphate battery
• Multi-stage protection design
• Compact design
• 9-100 kWh capacity range
• Floor stand mounting
• Up to 100% usable energy
  
  

Specifications

Benefits

The primary benefits of Sungrow batteries are their affordability, flexibility, and simplicity. Being on the budget end of the solar battery spectrum is always a plus, but these guys also don’t cut back on quality. The best part is that customers have options. With the High Voltage LFP battery, you can choose from a range of modules, and you only need another unit after you hit the maximum of eight modules. The design itself is small and compact, so you don’t need to worry about a big heavy unit taking up space.

Price

You can install a Sungrow High Voltage LFP battery for as low as $2500. The price obviously changes depending on what size system you’re getting, but compared to something like the Powerwall 2, it’s very budget-friendly. The smallest, three-module unit is typically enough to support the average Aussie household. At around $660 per kWh, it’s one of the more affordable lithium batteries on the current market.

Drawbacks

The High Voltage LFP battery is reliable, but there are some disadvantages. For example, their customer support hasn’t developed a solid track record. 

#1: AlphaESS SMILE-B3 PLUS

Image of AlphaESS SMILE-B3 PLUS

AlphaESS Smile-B3 Plus solar battery’s consistent high performance and retrofit ability have caused a spike in popularity with Australian providers. It’s easy to install and low maintenance. For Aussies looking to make an easy transition into renewables, AlphaESS should be a leading contender.

The Plico team have given it such a high score because the AlphaESS Smile-B3 Plus is durable and affordable, with a solid history of performance in Australia, thanks to their low cost point and ability to move large volumes of product. AlphaESS is moving with the times and their range of batteries and inverters are too. In terms of their Virtual Power Plant capabilities, Alpha battery systems can perform what is called Frequency Control Ancillary Services, something that will become all the more important as VPP grid services expand. In our opinion, these are the main boxes that need to be ticked! Add in the fact that it’s reasonably priced and you’re left with a high-performing battery that is accessible to a large portion of the market. 

Features

Some of the more notable features of AlphaESS batteries include:

• All-in-one module
• Modular design
• LFP technology
• 24/7 online tracking

The Smile-B3 Plus works with all solar inverters and comes Virtual Power Plant ready, meaning its performance and safety make it suitable to participate in VPPs. 

With the Smile-B3 Plus, you also get to experience LFP technology, one of the safest lithium battery types currently on the Australian market. That, coupled with an impressive temperature range of up to 50℃, makes this battery tough enough to withstand the harsh Aussie climate. 

Another big plus of the Smile-B3 Plus battery is that it looks great. The all-in-one module means everything is tucked neatly away and makes for hassle-free installation. 

Price

The cost of a Smile-B3 Plus battery is around $6,000. In relation to performance levels, this is cost-effective and definitely a solid option if you want to make a good return on your investment. Because it’s easily expandable, you’ll save on installation costs if you want more storage down the track. 

Drawbacks

Like every solar solution, the Smile-B3 Plus has a few drawbacks. Some reviews suggest AlphaESS customer service is somewhat lacklustre, so this is to keep in mind if you are buying direct. However, most solar equipment is purchased through a provider who completes the installation, so they would likely be your customer service representative. If you opt to purchase your solar battery under a subscription service like the one Plico provides, you can rest assured that they’ll deal with the manufacturer on your behalf should any issues arise.
