BYD HVS & HVM
in detail.
BYD is the world's largest battery manufacturer, and their HVS and HVM series are among the most popular home batteries installed in Australia.
Modular Design
Start with as little as 5.1 kWh and expand in 2.56 kWh increments up to 22.1 kWh. This flexibility means you can size your battery precisely to your needs and add capacity later.
LFP Safety
Lithium Iron Phosphate chemistry is inherently safer and more thermally stable than NMC alternatives. BYD's Blade Battery technology further enhances safety with its cell-to-pack design.
Inverter Flexibility
BYD batteries are compatible with a wide range of hybrid inverters including Fronius, GoodWe and SMA. This gives you more choice in system design and future upgrades.
Best suited for: Homeowners who want a flexible, scalable battery system with the ability to choose their preferred inverter brand. Ideal for larger homes or households planning to expand their storage over time.
Tesla Powerwall 3
in detail.
The Powerwall 3 is Tesla's latest home battery, featuring an integrated solar inverter and the most seamless backup experience on the market.
All-in-One Design
Powerwall 3 includes a built-in solar inverter, eliminating the need for a separate inverter. Fewer components means a cleaner installation and simpler system architecture.
Storm Watch
Powerwall monitors weather forecasts and automatically charges to 100% before severe storms arrive. This proactive backup feature is unique to Tesla.
Tesla Ecosystem
The Tesla app provides real-time monitoring of solar production, battery state, home consumption and grid usage. Integration with Tesla vehicles and energy products creates a unified experience.
Best suited for: Homeowners who value a premium, integrated experience with best-in-class backup power. Particularly appealing if you already own a Tesla vehicle or prefer an all-in-one system with minimal components.
Pylontech Force H2
in detail.
Pylontech is one of the world's largest energy storage manufacturers. Their Force H2 series offers reliable, modular storage at a competitive price point.
Budget-Friendly
Pylontech typically offers the lowest cost per kilowatt-hour of usable storage among the three brands. For homeowners focused on maximising storage capacity per dollar, Pylontech is a strong contender.
Proven Reliability
With over 1 GWh of residential installations globally, Pylontech has a well-established track record. Their LFP cells are rated for over 6,000 cycles, translating to many years of reliable service.
Stackable Modules
The Force H2 uses 3.55 kWh modules that stack to create systems from 7.1 kWh up to 21.3 kWh. Add modules as your energy needs grow without replacing your existing system.
Best suited for: Budget-conscious homeowners who want reliable storage without paying a premium for brand recognition. A practical choice for homes focused on self-consumption and reducing grid reliance.
Which battery
suits you?
There is no single best battery for every home. The right choice depends on your priorities, budget and how you plan to use your energy storage system.
Choose BYD
You want precise sizing with modular expansion, prefer to select your own inverter brand, or plan to start small and grow your storage capacity over time.
Choose Tesla
You want the most seamless backup experience, prefer an all-in-one system with built-in inverter, or value the Tesla app and ecosystem integration.
Choose Pylontech
You want to maximise storage per dollar, are focused primarily on self-consumption savings, or prefer a no-frills approach to energy storage.
