  Homeowners and businesses across Australia are increasingly pairing rooftop solar panels with energy-storage batteries. A solar battery stores surplus electricity produced during daylight hours for use later at night or during an outage. It gives property owners more control over the electricity they generate, reduces reliance on the grid, and can even provide income through feed-in tariffs or virtual power plant (VPP) schemes. However, batteries are not without drawbacks. They involve a significant upfront cost, and their environmental footprint depends on how they are manufactured and recycled. This article from  Solar National  looks at how solar batteries work, the main types available, the advantages and disadvantages of installing one in a Sydney home, and answers frequently asked questions. It draws on independent research and government information from 2024–2025 to help you decide whether a solar battery is right for you. How a Solar Battery Works A solar batt...

  The solar inverter market in Australia is heating up — and not from the sun. In 2025, both  Sungrow  and  SolarEdge   have rolled out aggressive trade-in programs offering households rebates and tech upgrades. These aren’t just discounts—they’re incentives for Australians to modernise their energy setups with hybrid inverters and battery-ready systems, while responsibly disposing of aging hardware. Sungrow claims over  400,000 residential systems   installed across Australia, while SolarEdge offers up to  12-year warranties  with their trade-up plans. Whether you’re looking to upgrade, improve backup capabilities, or align with energy providers’ new phase balancing rules, this guide breaks down everything about both offers and what they really mean for your home—and your wallet.

  In September 2025, the Australian Competition and Consumer Commission (ACCC) officially announced a safety recall for certain GoodWe EHB series and GE branded GEH series hybrid inverters sold across Australia. The root of the issue lies in a bypass‑switch bug: when the inverter is placed in “bypass” mode while operating in backup mode, it can continue exporting power to the grid. In the event of islanding (i.e. the grid is down), this raises a serious risk of electric shock to workers or consumers. This recall again highlights that even well‑regarded solar inverters like GoodWe are not immune to design or firmware flaws. If you own a GoodWe or GE hybrid inverter, it’s essential to act quickly, check your firmware version, and avoid using the bypass switch until the fix is confirmed. In this article, we’ll break down what’s going on, what common GoodWe inverter problems look like, and what steps you should take now to protect your system and your safety.

  As the push for clean energy solutions continues to gain momentum across Australia, solar batteries have become an essential part of many homes and businesses. Among the most popular options is the  Tesla Powerwall 2 , a home battery system that stores energy from solar panels for use during the night or in power outages. However, recent news has caused concern among Australian consumers. Tesla has issued a recall for some  Powerwall 2  units due to safety risks. In this blog, we’ll explore what we know about the recall, the potential risks, and how you can protect your investment in solar energy. What Is the Tesla Powerwall 2? Before delving into the recall specifics, let’s quickly review what the  Tesla Powerwall 2  is and why it’s so widely used . The Powerwall 2 is a lithium-ion battery storage system designed to store excess energy generated by solar panels. This allows homeowners to have access to renewable energy even when the sun isn’t shining. I...

  Choosing the right solar battery can make all the difference in how much value you get from your solar system. With electricity costs climbing, more Australians are turning to battery storage to maximise savings and ensure backup power when it’s needed most. A good solar battery comparison usually comes down to a few key factors: capacity (kWh), depth of discharge (DoD), cycle life, efficiency, warranty, and cost. Lithium-ion options, especially LiFePO₄ batteries, have become the most popular because they offer long lifespans and safer performance. Meanwhile, modular batteries give households the flexibility to expand storage as energy needs grow. When weighing up options, it’s also important to consider whether your goal is to cut bills, increase energy independence, or have reliable backup power during outages. Each brand and model brings different strengths—some excel in affordability, while others focus on durability or higher storage capacity. At Solar National , we help h...

  Powering your home when the sun goes down requires more than just solar panels. The right battery system lets you store sunshine for later, cut bills and keep the lights on during outages. This guide compares popular solar batteries available in 2025, explains different battery chemistries, outlines government rebates and helps Australian households decide which storage solution is best for them. Why consider a solar battery in Australia? Australia’s love affair with rooftop solar continues. By mid‑2025, more than 3.5 million homes had solar panels and many households were exploring batteries. Several factors make 2025 a particularly attractive time: Rising electricity prices and shrinking feed‑in tariffs:  Day‑time export rates have fallen below $0.05 per kWh in some states, reducing the return from sending solar back to the grid. Using a battery to self‑consume solar generation protects households from higher retail tariffs. Cheaper Home Batteries Program:  The fede...
