For investors and project finance institutions, this is a direct argument for low counterparty risk and confidence in long-term after-sales support. - **High efficiency: 98.4% peak / 97.9% EU** - The SH10RT achieves a peak efficiency of 98.4% and a weighted EU efficiency of 97.9%, placing it among the top three-phase hybrid inverters on the market (Fronius Symo GEN24 Plus: ~98.0% peak). EU efficiency is a better predictor of real-world energy yield under Poland's variable irradiance conditions than the single peak-power test point. - **EPS switchover in under 20 ms** - Emergency Power Supply (EPS) switchover time is \<20 ms (single-phase RS models are rated \<10 ms). In practice, most household loads - consumer electronics, computers, and refrigerators - remain powered without interruption, a significant advantage over off-grid inverters with switchover times exceeding 100 ms. - **10-year warranty included as standard** - Sungrow covers the entire SH series with a standard 10-year warranty at no additional cost, whereas some competitors (e.g., Huawei SUN2000 - 5-year base warranty, extension sold separately) require purchasing a service package. This translates directly into a lower total cost of ownership over the system's lifetime. - **Dual MPPT, 200-950 V DC input range** - Two independent MPPT trackers with a wide voltage window of 200-950 V DC allow string arrays to be designed across multiple orientations (e.g., east-west-south) and minimize energy losses under partial shading conditions - without requiring a power optimizer on every module. ### Cons - **Closed battery ecosystem** - Full BMS integration, unified monitoring, and system-level warranty coverage are available exclusively with Sungrow's own SBR battery series. Connecting third-party batteries requires manual verification of voltage range compatibility and communication protocols, and certain features - such as SOC prediction within iSolarCloud - may not function correctly. - **Limited third-party HEMS integration** - The Modbus interface on SH-series inverters can be difficult to parse for third-party home energy management systems (reported issues include incorrect battery SOC readings in evcc - GitHub issue #5394). Installations with advanced building automation or third-party EV chargers typically require additional configuration work or the use of protocol gateways. ## About this series The Sungrow SH series are **three-phase hybrid inverters** designed for grid connection and energy storage integration, performing excellently in homes and small commercial properties where self-consumption and backup power are crucial. Their key advantage is **multi-string MPPT** - independent trackers allow managing PV strings with different orientations (e.g., east-west) and minimize losses during partial shading, effectively stabilizing energy yield throughout the day. The high European efficiency means the inverter maintains excellent performance in typical, variable Polish operating conditions - not just at the ideal test point, translating to more energy delivered for consumption or storage. Daily operation is supported by **iSolarCloud monitoring** with a user-friendly app and communication via WiFi or Ethernet, along with integration capabilities through standard interfaces. This solution is tailored for investors seeking an efficient PV-battery system while expecting proven grid certificates and a **long warranty period** for peace of mind for years to come. ## Questions ### What warranty does Sungrow offer on its SH-series hybrid inverters? Sungrow provides a 10-year manufacturer's warranty on the SH-series hybrid inverters, covering material and manufacturing defects. This is one of the longer standard warranties in this product class, which is particularly important for energy storage investments designed to last at least 20 years. ### How many SBR battery modules can be connected to a Sungrow SH RT inverter? A single SH RT series inverter supports between 3 and 8 SBR battery modules. Each module has a capacity of 3.2 kWh, yielding a maximum of 25.6 kWh of energy storage per inverter. For higher capacity requirements, two identical systems can be operated in parallel, effectively doubling the available storage capacity. ### How quickly does the Sungrow SH inverter switch to backup power from the battery? The switchover to backup mode occurs in under 20 milliseconds from the moment grid voltage is lost. In practice, this means that sensitive household devices such as computers and refrigerators will not register the interruption. The minimum backup state of charge for the battery can be configured remotely via the iSolarCloud app. ### Is the Sungrow SH inverter suitable for rooftop installations with an east-west panel orientation? Yes, the SH series is particularly well suited for such configurations. The SH10RT model, for example, features four independent MPPT trackers, allowing strings on different roof faces to operate independently, each tracked at its individual maximum power point. This minimizes losses that would otherwise amount to several percentage points of annual energy yield when using a single-MPPT inverter. ### What efficiency does the Sungrow SH hybrid inverter achieve and what does that mean in practice? The peak efficiency is 98.4%, and the high European efficiency rating ensures strong performance under variable irradiance conditions typical of temperate climates, not just under ideal test conditions. In practice, this means that more energy from every kilowatt-hour generated reaches the home or battery storage, with minimal thermal losses in the inverter. ### How does iSolarCloud monitoring work with Sungrow SH inverters and does it require an additional device? SH-series inverters feature a built-in Wi-Fi or Ethernet communication module that connects directly to the iSolarCloud platform without the need for a separate data logger. Through the free mobile app, users can monitor generation, consumption, and battery state of charge, and remotely adjust operating parameters including backup mode settings and charging schedules. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/inverters/ds-20231201-sh15-20-25t-datasheet-v3-en-450fc75bfc3e.pdf) ## Alternatives | Inverter | Rated AC | Euro efficiency | MPPT | Weight | Difference | | --- | --- | --- | --- | --- | --- | | [Huawei SUN5000-25K-MB0](https://comparepv.com/inverter/huawei-sun5000-25k-mb0) | 25 kW | 98.2% | 2 | 21.0 kg | +0.4 pp efficiency, -1 MPPT, 19.0 kg lighter | | [Huawei SUN2000-25K-MB0](https://comparepv.com/inverter/huawei-sun2000-25k-mb0) | 25 kW | 98.2% | 2 | 21.0 kg | +0.4 pp efficiency, -1 MPPT, 19.0 kg lighter | | [Fronius Verto 25.0 Plus](https://comparepv.com/inverter/fronius-international-fronius-verto-25-0-plus) | 25 kW | 97.7% | 3 | 43.0 kg | 3.0 kg heavier | | [Growatt WIT 25K-XHU](https://comparepv.com/inverter/growatt-wit-25k-xhu) | 25 kW | 97.2% | 2 | 45.0 kg | -0.6 pp efficiency, -1 MPPT, 5.0 kg heavier | | [Growatt WIT 25K-HU](https://comparepv.com/inverter/growatt-wit-25k-hu) | 25 kW | 97.0% | 2 | 55.0 kg | -0.8 pp efficiency, -1 MPPT, 15.0 kg heavier | | [Deye SUN-25K-SG01HP3-EU-AM2](https://comparepv.com/inverter/deye-sun-25k-sg01hp3-eu-am2) | 25 kW | 97.0% | 2 | 30.5 kg | -0.8 pp efficiency, -1 MPPT, 9.5 kg lighter | | [Growatt MID 25KTL3-XH](https://comparepv.com/inverter/growatt-mid-25ktl3-xh) | 25 kW | | | 31.0 kg | 9.0 kg lighter | | [Huawei SUN2000-25K-MB0-ZH](https://comparepv.com/inverter/huawei-sun2000-25k-mb0-zh) | 25 kW | | 2 | 21.0 kg | -1 MPPT, 19.0 kg lighter | --- Source: https://comparepv.com/inverter/sungrow-sh25t
