The solar inverter market in Australia is heating up — and not from the sun. In 2025, both Sungrow and SolarEdge have rolled out
Sungrow’s 2025 trade-in offer is focused on modernising older solar inverter setups by giving homeowners financial incentives to switch to their newer, smarter hybrid inverters. If you’ve got an outdated system that’s out of warranty or starting to show reliability issues, Sungrow’s rebate might be the cost-saving upgrade path you’ve been waiting for.
Sungrow is pushing to increase its market share while also reducing e-waste. The program makes it easier for households to shift towards battery-ready solar inverter systems, which is where most of Australia’s residential energy market is headed.
Sungrow inverters are generally well-reviewed for reliability, affordability, and smart features, especially their hybrid models. They’re widely used in Australia and backed by long warranties, making them a solid choice for both new and upgrading solar users. Overall, their performance and value place them in the top tier of residential inverter brands.
SolarEdge is also offering a compelling trade-in program—but it targets a different type of solar user. While Sungrow focuses on affordability and hybrid convenience, SolarEdge aims at those looking for higher efficiency, enhanced safety, and detailed panel-level monitoring. Their trade-in offer is part of a global strategy to phase out older string inverter models in favour of more advanced, optimiser-based technology.
SolarEdge inverters are known for using optimisers, which maximise the output of each individual panel. This is particularly useful for homes with shading issues or variable roof orientations. The trade-in program is ideal for homeowners who want more control and transparency over their solar system’s performance.
If you’re weighing up whether to go with Sungrow or SolarEdge for your solar inverter upgrade, your decision will likely come down to budget, system goals, and long-term energy plans. Here’s how they stack up against each other in Australia’s 2025 trade-in market.
| Feature | Sungrow Inverter Offer | SolarEdge Inverter Offer |
| Rebate Offer | Available on select models | Available on select models |
| Warranty | Up to 10 years | Up to 12 years |
| System Type | String & hybrid | Optimiser-based |
| Monitoring | iSolarCloud app (basic to advanced) | Panel-level insights via Smart Energy Suite |
| Battery Compatibility | High – supports many third-party batteries | Native SolarEdge battery support |
| Price Point | More affordable upfront | Higher upfront, long-term efficiency gains |
| Target Users | Budget-conscious, hybrid-ready | Tech-focused, performance-driven |
For users who want a cost-effective hybrid inverter, Sungrow offers great value. But if you’re after panel-level performance and system insights, SolarEdge has the edge—though at a premium. It’s not a matter of better or worse, but fit.
Upgrading your solar inverter isn’t just about chasing the latest tech — it’s about improving your system’s reliability, futureproofing for battery storage, and making sure you’re not throwing money away on inefficiencies. Both Sungrow and SolarEdge are tapping into these real-world concerns with their trade-in programs.
Newer inverters from both brands are battery-compatible. This matters because the future of solar in Australia is hybrid. Whether you’re installing a Tesla Powerwall, a Sungrow SBR, or SolarEdge’s own battery, having a hybrid-ready inverter is essential.
Older inverters are more prone to faults and breakdowns, often outside warranty. New models come with longer warranties (10–12 years) and better thermal management, which means fewer shutdowns and maintenance issues.
If you’re still using an inverter without real-time data, you’re flying blind. Sungrow’s iSolarCloud and SolarEdge’s Smart Energy Suite give you detailed, app-based control over your system’s health, efficiency, and energy usage.
With changing grid standards in Australia, especially around voltage management and export controls, many older inverters no longer meet provider requirements. Upgrading ensures you’re compliant and less likely to face penalties or restrictions.
Before jumping into a trade-in offer, it’s worth taking a moment to check if the upgrade truly suits your system and goals. While rebates and extended warranties sound appealing, there are a few things you should confirm to make sure your investment pays off.
If your inverter is more than 7–10 years old, you’re likely out of warranty and facing declining efficiency. But if it’s still under warranty and working well, trading in might not be urgent unless you’re upgrading for battery compatibility.
Ensure the new inverter works with your existing solar panels and, if applicable, your battery or energy management system. Some older panels may not be supported by newer optimiser-based systems like SolarEdge unless additional components are installed
Get a written quote showing the full cost of the upgrade minus the rebate. Rebates may not cover installation or additional hardware (like optimisers or smart meters). Compare final pricing between Sungrow and SolarEdge for an honest cost–benefit analysis.
Look at what’s included in the extended warranty—some only cover hardware, not labour or callouts. Also check the brand’s reputation for honouring warranties and providing support in Australia.
For many Australian homeowners, the decision to upgrade depends on balancing cost, urgency, and system goals. With electricity prices continuing to rise and solar feed-in tariffs dropping, having a smart, efficient solar inverter can significantly affect your return on investment.
Both Sungrow and SolarEdge provide well-supported trade-in options that help reduce waste, save money, and bring your solar system in line with modern standards. But timing, system condition, and your long-term solar strategy will ultimately decide whether now is the right time to upgrade.
With both Sungrow and SolarEdge offering competitive trade-in programs across Australia in 2025, now is the right time to consider upgrading your outdated solar inverter. These brands are not just offering rebates — they’re helping homeowners futureproof their solar systems with smarter technology, extended warranties, and better energy efficiency.
