How Much Is a 6.6kW Solar System With a Battery?

  Installing a 6.6 kW solar system with a battery is one of the most common and effective solar setups for Australian households. It offers the ideal balance of energy output, system cost, and long-term value — especially when paired with the right-sized battery and a quality installer. In 2025, the average cost of a 6.6kW solar system with a battery in Australia ranges from $9,500 to $14,000, depending on the components and installation quality. Without a battery, the same system may cost $5,500 to $7,000. A 10 to 13kWh solar battery typically adds $4,000 to $8,000 to the total price, depending on the brand and features. Why Is the 6.6kW Solar System So Popular in Australia? The 6.6kW system is suited to the needs of most medium-to-large Australian households. It includes about  16 to 18 solar panels  and usually connects to a  5kW inverter  — the largest inverter size eligible for full feed-in tariffs in many states. Why Australians choose this system: Output ...

What Are the Pros and Cons of Solar Batteries?

  In recent years, the uptake of rooftop solar has surged across Australia, but many homes still export excess energy to the grid during the day and draw power from the grid at night. Solar battery systems – essentially large rechargeable batteries connected to your solar panels – offer the promise of storing that daytime energy for use after sunset. Whether you live in metro Sydney or regional Western Australia, the idea of near‑complete energy independence can be enticing. Before rushing into a purchase, however, it is worth weighing the pros and cons of battery storage and considering how your household uses energy.  Government guides warn that batteries can be  relatively expensive  and that pay‑back periods can extend beyond a decade if systems are not sized correctly. This article explores the benefits, drawbacks and practical considerations of solar batteries so you can decide if they suit your needs. What is a solar battery? A solar battery is an energ...

Sungrow & SolarEdge Trade-In Program: Upgrade Your Solar Inverter in 2025

  As solar technology advances, many Australian homeowners are looking for ways to future-proof their systems. One of the fastest routes to more efficient, battery-ready solar is through  trade-in and trade-up programs  offered by inverter manufacturers. In 2025, both  Sungrow  and  SolarEdge  are running schemes that let you upgrade older inverters to the latest hybrid models — and, in some cases, add a  solar battery  at a discounted price. This guide from  Greenlight Solar  explains how these programs work, who qualifies, and why upgrading your inverter is a smart move. It draws on official manufacturer information and industry analysis so you can make an informed decision. Why Upgrade Your Solar Inverter in 2025? Older string inverters may still produce electricity, but they lack features many households now expect. New hybrid inverters support battery storage, integrate with monitoring platforms, and offer higher efficiency...

GoodWe & GE Hybrid Inverter Recall 2025: Firmware Fix

In late September 2025 the Australian Competition & Consumer Commission (ACCC) published a product safety recall covering certain GoodWe EHB and GEH series hybrid inverters. These “hybrid” solar inverters work with solar batteries so that households can store excess solar energy for use after dark. Because GoodWe has sold tens of thousands of inverters in Australia since 2012, the recall naturally generated concern among homeowners and installers. This article summarises the recall, explains which models are affected, describes the remedy, and answers common questions about GoodWe’s products. Why were GoodWe and GE hybrid inverters recalled? The ACCC recall notice explains that the bypass switch on the affected inverters could allow the unit to continue exporting power to the grid when operating in backup mode. When the bypass switch is accidentally turned to ‘bypass’ while the grid is down, the inverter keeps sending electricity back into the grid. In an islanding situation, ...
