Sungrow SH Hybrid Inverter Review Australia: SH5.0RT and SH10RT Models

Key Takeaways

• The Sungrow SH series offers 3-phase hybrid inverters, including the 5kW SH5.0RT and 10kW SH10RT models, designed for the Australian market.
• These inverters provide rapid backup power, with a transition period less than 20ms during grid outages.
• They support 100% unbalanced loads in off-grid mode, making them suitable for a wide range of household appliances.
• The SH series is compatible with specific LG Chem RESU and BYD Battery-Box Premium battery models.

Understanding the Sungrow SH Hybrid Inverter Series for Australia

The Sungrow SH series of hybrid inverters, specifically the SH5.0RT and SH10RT models, are designed to integrate solar power generation with battery storage for homes and businesses in Australia. These 3-phase inverters offer both grid-tied operation and backup power capabilities, ensuring energy independence and continuity during grid interruptions.

The SH5.0RT model provides 5kW of output power, while the SH10RT model offers a higher 10kW output. Both models feature two Maximum Power Point Trackers (MPPTs), allowing for flexible solar array design and optimised energy harvesting from different roof orientations or shading conditions.

How Sungrow SH Hybrid Inverters Manage Power

Sungrow SH hybrid inverters operate by intelligently managing the flow of electricity between your solar panels, batteries, home loads, and the grid. During daylight hours, solar energy powers your home and charges your battery. If solar production exceeds demand, excess energy can be exported to the grid (subject to local regulations). When solar production is low or at night, the inverter can draw power from the battery or the grid to meet your home's needs.

A key feature of these inverters is their ability to provide Uninterrupted Back-up Power Supply. In the event of a grid failure, the inverter can seamlessly switch to battery power, with a Transition Period less than 20ms. This rapid response ensures that essential appliances continue to operate with minimal disruption. Furthermore, the SH series is designed to Support 100% Unbalanced Loads in Off-grid Mode, meaning it can handle varying power demands from different types of appliances, from air conditioners to microwaves.

Compatible Battery Systems for Sungrow SH Inverters

The Sungrow SH5.0RT and SH10RT hybrid inverters are designed to work with specific high-voltage battery systems, ensuring optimal performance and reliable energy storage. Compatibility is crucial for proper communication and operation between the inverter and the battery.

The following table outlines the battery models officially supported for pairing with the Sungrow SH5.0RT and SH10RT inverters:

When installing these systems, it is important to ensure that the correct battery type is selected and that the inverter's firmware is up to date to support the chosen battery. The inverter's integrated design means there is No need for external controllers or communication cabling for frequency shifting in off-grid mode, simplifying the overall system architecture.

What you can change yourself, and what you cannot

As an owner of a Sungrow SH hybrid inverter, you typically have control over certain operational parameters through the inverter's interface or a connected monitoring application. These might include setting preferred operating modes (e.g., self-consumption, time-of-use), battery charge/discharge schedules, and monitoring system performance.

However, certain settings, particularly those related to grid protection, export limits, and specific battery charging profiles (beyond selecting the battery type), are usually configured by a registered installer. Altering these settings without proper authorisation can void warranties, compromise system safety, and potentially breach your connection agreement with your electricity network service provider. Always consult a qualified and registered electrician or solar installer for any changes to grid-facing or safety-critical parameters.

What the published sources do not tell you

While the provided documentation offers essential details about the Sungrow SH5.0RT and SH10RT hybrid inverters, there are several areas where specific information is not explicitly stated. For instance, the maximum efficiency and the full MPPT voltage range for both models are not detailed in the available documents. Similarly, the exact battery voltage range that these inverters operate within is not specified.

The standard warranty duration for the SH5.0RT and SH10RT models is also not provided in the reviewed materials. Furthermore, detailed error or fault codes, their meanings, and specific troubleshooting steps are not included. Information regarding specific app names for monitoring, port names, or detailed setup steps for Wi-Fi connectivity or data logging are also absent. The documents are dated 2020, which means some specifications or compatible battery models might have been updated since then. For the most current and comprehensive information, it is always best to refer to the latest official Sungrow product manuals and datasheets available on their Australian support website.
