• Anti-Corrosion: Specific models also offer C5 anti-corrosion protection, further enhancing their resilience in coastal or harsh environments.

6. Understanding Sungrow's Product Range for 2025

Sungrow offers a diverse portfolio catering to various needs, from small residential setups to large-scale commercial projects.

Residential Inverters (SG Series)

For homeowners, the single-phase SG series remains a popular choice, ranging from 2kW to 10kW. These typically feature:

• High efficiency.
• Multiple MPPTs (Maximum Power Point Trackers) for optimising energy harvest from panels on different roof orientations.
• Compact design and quiet operation.
• The SH5/6/8/10RL hybrid inverter series (up to 10kW) is also a strong residential offering for those considering battery storage.

Commercial & Industrial (C&I) Solutions

Sungrow continues to innovate in the C&I space. The new SH125CX hybrid inverter with a nominal output of 125kW, often paired with the PowerStack 255CS liquid-cooled ESS, is a prime example of their advanced offerings for larger commercial applications. These are designed for flexibility, scalability, and robust performance.

Hybrid Inverter Technology: Integrating Storage Seamlessly

As battery storage becomes increasingly prevalent in Australia, Sungrow's hybrid inverters are a key highlight for 2025. These inverters are designed to:

• Manage energy flow between solar panels, batteries, and the grid.
• Optimise self-consumption by storing excess solar for later use.
• Provide backup power during grid outages (with appropriate battery configuration).
• Offer compatibility with a range of batteries, including their own SBH and SBS battery series.

Battery Compatibility: Sungrow's Integrated Approach

Sungrow offers excellent compatibility with their own line of batteries, such as the SBH and SBS series, which feature LFP (Lithium Iron Phosphate) technology for enhanced safety and longevity. This integrated approach ensures seamless communication and optimised energy management between the inverter and battery.

Smart Monitoring with iSolarCloud App: Your Energy Dashboard

A crucial aspect of any modern solar system is its monitoring capabilities. Sungrow's iSolarCloud app and web platform provide real-time insights into your system's performance, energy production, and consumption. Key features include:
