Compare home battery options

Sungrow, Sigenergy, and ESY Sunhome are all eligible for various state-based programs, and their modular design allows cost-effective expansion without replacing the original system. Depth of Discharge (DoD) indicates the percentage of battery capacity you can use without significantly affecting its longevity. While Sigenergy batteries technically support 100% DoD under optimal conditions, a DoD of 80%–90% is generally recommended to maximize cycle life and extend the overall lifespan of the battery. High cycle life ensures the battery can last many years even with frequent daily cycling, making Sigenergy suitable for high-usage households. At Stag Electrical, we trust a select group of battery brands for our installations, including Sungrow, Sigenergy, ESY Sunhome, and Goodwe. This guide explains why these brands are excellent choices and how they compare to other top brands in Australia.
Sigenergy’s battery is redefining the market with its AI-powered features and built-in DC fast EV charging. IP55-rated to withstand harsh weather, the IQ 5P also has an industry-best 15-year warranty that guarantees lasting performance. Use the Storm Guard feature in the Enphase App to monitor approaching extreme weather conditions to keep your home prepared for power outages. Choosing a battery with these features ensures you get the most out of your solar system while protecting your investment, enjoying energy independence, and keeping your home safe. Sigenergy is one of the newer entrants in Australia (launched 2023) but packs strong specs and modular hybrid design. Its high-end safety features make it appealing for commercial solar battery sumner tech-savvy buyers.

Each kWh of usable capacity creates 6.8 certificates at the full rate, and at a certificate price of $38 that is about $258/kWh on the first 14 kWh. Capacity from 14 to 28 kWh earns 60% of that, about $155/kWh, and capacity from 28 to 50 kWh earns 15%, about $39/kWh. The practical effect is that household-sized batteries keep most of the discount, while very large batteries get a smaller one per kWh. Selecting the perfect solar battery depends on your energy goals, budget, and household needs. Whether you prefer affordability, premium features, or cutting-edge tech, there’s a solar battery for you.
You may pay quite different amounts depending on the season – but a guesstimate here is fine. The calculator default is the average electricity bill for a home in your state. The calculator estimates the current price based on the selected model; but feel free to change the cost if you have a good deal. A competent installer will assess your needs before making a recommendation.
MANLY focuses almost entirely on the battery modules themselves, often selling them directly to installers or consumers looking for a cost-effective block of storage. Thanks to features like the max 2.0 DC/AC ratio, the system can really squeeze every last drop of energy out of your panels. It’s an all-in-one system, meaning the battery, the essential hybrid inverter and the smart control system are bundled into one tidy box. This guide will break down the top solar batteries in Australia right now, including key features and a simple explanation of who each one suits best. More families want to run their homes at night on stored solar to avoid relying on expensive grid power and have backup protection during blackouts. "Comparing battery quotes was super easy! Thanks ABQ, we found the perfect solar and battery system for our home and saved so much time and money."

Our guide to the pros and cons of solar batteries makes the honest case both ways. If you want the whole house running through an outage, the Powerwall 3 and SigenStor lead on output capacity. If backup is a nice-to-have and lower bills are the real goal, the value brands do that job for far less money.
For example, the Tesla App’s ‘Charge-On-Solar’ feature broke about three months ago and refuses to charge my car from my 20kW of solar. I’ve now given up on it and pay $7 per month to ChargeHQ for solar charging instead. I’ve had my Powerwall 2 since 2016, and I installed a Sungrow battery on my rental property in 2023.

Always check your policy details and discuss your battery system with your insurer to ensure adequate protection. The cost of a 5kW battery can vary depending on several factors, including brand, model, system complexity, and installation costs. If you have a high daily electricity consumption or want to store more energy for backup purposes, you may need a larger battery.
The SolaX battery performed reliably after being installed in 2020 as part of Phase 3, but the energy and state of charge discharged per cycle started to drop off rapidly. An issue was identified with the battery modules and the whole unit was replaced in July 2021. The new sample ran reliably until the end of the trial in March 2022, with only minor capacity fade (down to 98% after 600 cycles). The Redflow battery is another interesting non-lithium battery, being a ‘flow’ battery that uses a pumped zinc bromide electrolyte liquid to store and release charge. Unfortunately, the tested samples have suffered several electrolyte leaks or contamination and the battery was replaced five times over the course of the trial. This interesting battery is not lithium-ion or lead-acid – instead it uses a salt water electrolyte.
With a usable capacity of 13.5 kWh and a 100% Depth of Discharge, it provides substantial energy autonomy, especially when paired with a sizable rooftop solar array. If you're one of the 4 million Aussie homeowners with solar panels, you've won the first half of the energy game. Stop gifting your hard-earned solar to the retailers for a pittance.

The best type of battery for you depends on your budget, needs, and location. A lead-acid battery may be a good choice if you are looking for an affordable and reliable option. A lithium-ion battery may be a better choice if you are looking for the most efficient and lightweight option.
We design custom solar power systems for Australian homes and businesses, offering end‑to‑end services—from design and installation to monitoring, battery storage, and ongoing support. Explore our battery and storage solutions available in Adelaide, featuring advanced technology from leading brands like Tesla, Alpha Ess, Growatt. Designed to integrate seamlessly with your solar panel system, our batteries offer efficient, reliable energy storage for both residential and commercial needs. Fox ESS and GoodWe are not in the table because they are usually quoted as a complete hybrid inverter and battery package rather than a battery on its own.

Once the sun goes down, you draw power from the national grid and pay for it. Add a solar battery, and you can store that excess solar power in the evenings. Weather conditions affect how much energy your Australian-made solar panels can generate. But on a sunny day with clear skies, you can expect a 10kW solar energy system to produce around 40kWh of energy per day. This should be ample power to run most Australian households, but it’s important to remember that every home is different. It’s always best to consult your Tindo Solar experts to get the best-size solar system for your needs.
