Battery 101: The Ultimate Guide to Solar Battery Storage in Australia

Looking to take full control of your energy and reduce your reliance on rising electricity prices? A solar battery is your key to storing solar power, using it at night, backing up your home in blackouts — and even charging your electric car or powering smart home features. At Yello Energy Group, we deliver CEC-approved, future-ready battery systems that match your lifestyle, usage, and goals.

What is a Solar Battery?

A solar battery stores unused electricity generated by your solar panels during the day. Instead of sending it back to the grid for a low feed-in rate, you store it and use it later — at night, during cloudy days, or when grid power goes down.

It means:

More savings
More energy independence
More control

Batteries with Built-In Smart Home & Automation Features

Some batteries don’t just store power — they help you run a smarter home. Brands like Sigenergy, Tesla, and Goodwe offer:

Smart Load Management

Auto-control when appliances run (e.g., heat pumps, dishwashers, pool pumps)

Time-of-Use Optimisation

Use stored energy during expensive grid times and recharge during cheaper periods.

App & Voice Control

Adjust battery behavior via mobile app or with Alexa/Google Assistant.

Priority Backup Zones

Power specific parts of your home during outages (e.g., fridge, lights, internet)

It’s not just energy storage — it’s smart energy orchestration.

Types of Solar Batteries We Install

We supply top-tier lithium battery systems from leading brands known for safety, performance, and long-term value:

Lithium-Ion (Li-ion)

Standard in most home battery systems.
Lightweight, compact, and efficient.
Brands: Tesla, Growatt, Goodwe, SAJ, Dyness, BYD, Sigenergy.

Lithium Iron Phosphate (LFP)

Safer and more thermally stable than standard Li-ion.
Ideal for high-heat Aussie conditions and deep cycling.
Longer lifespan, better reliability

All our batteries are VPP-ready, smart-home compatible, and can integrate with new or existing solar systems.

Can a Battery Charge My Electric Vehicle?

Yes — and directly, too.

If you have a hybrid inverter or DC-coupled system, your battery can:

Charge your EV using stored DC power, reducing conversion losses.
Work alongside solar EV chargers like Zappi or Fronius Wattpilot.
Prioritise EV charging when solar is abundant.
Keep your car powered during grid outages (if vehicle-to-load or V2H is supported)

This is perfect for anyone wanting to run their car on sunshine, even at night.

AC vs DC Coupled Battery Systems

Type	Best For	Key Advantage
AC Coupled	Retrofit systems	Flexible and easier to install
DC Coupled	New installations	More efficient, direct solar input

Need help deciding? Yello’s designers will select the ideal configuration based on your solar setup and lifestyle.

What Size Battery Do You Need?

Home Size	Daily Energy Use	Battery Size Suggestion
1–2 people	5–10 kWh	5–6.5 kWh
3–4 people	10–20 kWh	10–13.5 kWh
Large homes/Business	20+ kWh	13.5–30+ kWh

You can also stack batteries to grow your system over time — especially important for EV owners and electric hot water users.

Rebates & Incentives Available in Australia (2025)

Battery systems are more affordable than ever, thanks to government rebates:

VIC Solar Homes Program – Up to $4,174.
NSW Peak Demand Reduction Scheme – Vouchers & incentives.
SA Home Battery Scheme – Up to $2,000.
ACT Next Gen Program, plus federal support under Net Zero 2050..

Yello handles all rebate paperwork — we’ll make sure you claim everything you’re eligible for.

Warranty, Safety & Lifespan

10–15 year warranties on most batteries.

6,000 to 10,000+ cycles (that’s 15+ years of daily use)

Advanced BMS (Battery Management Systems) for safety.

Overcharge, overheat, and surge protection built in.

All systems are Clean Energy Council (CEC) approved.

Will My Battery Work During a Blackout?

Not all batteries provide backup during power outages by default. To keep your lights (and fridge, Wi-Fi, or even EV charger) running during a blackout, your system must be designed with backup protection.

What Do I Need for Backup Power?

To enable blackout functionality, your solar battery system must include:

Backup wiring and switchboard isolation.
A compatible hybrid inverter with backup mode.
Uninterruptible Power Supply (UPS) features for sensitive devices.
Correct sizing to support essential loads.

What is UPS (Uninterruptible Power Supply) in Solar Batteries?

UPS ensures that essential appliances stay on instantly if the grid goes down — without any delay or flicker.

Seamless transition from grid to battery power (usually < 20 milliseconds)
Prevents computer crashes, modem resets, and food spoilage.
Critical for medical devices, alarm systems, and home offices.

Batteries like Tesla Powerwall, Goodwe Lynx, and Sigenergy SigenStor offer integrated UPS functionality — but only when installed with backup circuits.

Yello Energy will work with you to:

Identify which circuits to protect (e.g. fridge, modem, lights, EV charger)
Design your switchboard for backup power.
Ensure compliance with Australian Standards for safety and performance.

VPP – Earn Money from Your Battery

Some batteries let you earn cash or bill credits by joining a Virtual Power Plant (VPP). It’s like putting your battery to work while you sleep.

Check out our VPP 101 article to learn how it works and how much you can earn.
