In practice, this eliminates LED flicker and prevents resets in voltage-sensitive devices (NAS drives, routers, A+-rated refrigerators), delivering real-world ride-through comfort comparable to online UPS systems. - **100% rated power at 45°C - zero derating** - The MG5RL/MG6RL maintains full nominal output up to 45°C ambient temperature. Competing models (Fronius Gen24 Plus, Huawei SUN2000-5/6KTL-L1) begin derating at approximately 40°C, which translates into measurable seasonal yield losses in heated utility rooms or technical enclosures during Central European summers. - **20 A PV string input (2× MPPT)** - The industry standard hovers around 12-15 A ISC; support for up to 20 A per string allows direct connection of the latest high-power bifacial modules (575-600 Wp, ISC ~19-20 A) without parallel string wiring. Two independent MPPTs enable optimization across roof faces with differing azimuths or shading conditions. - **Compatibility with 50+ third-party battery brands** - The officially certified list covers more than 50 battery brands (including Pylontech, BYD, and CATL), which is well above average for single-phase 5-6 kW hybrids. In practice, this protects the end customer against ecosystem lock-in and gives installers the flexibility to source storage competitively. - **AFCI + IP65/C5 as standard** - Built-in arc-fault circuit interruption (AFCI) is increasingly required by European insurers and local fire-safety regulations. Corrosion category C5 (marine and industrial environments) permits installation in chemically aggressive locations, exceeding the requirements of typical residential prosumer systems. ### Cons - **Limited field track record (launched July 2025)** - The series officially debuted at the Southeast Asia Distribution Summit in July 2025. As of May 2026, fewer than twelve months of operational data from Central European deployments are available. Installers who require a multi-year field track record may prefer the more mature Sungrow SH-RS series or competitors with documented performance histories under Polish climatic conditions. ## About this series The Sungrow MG5RL/MG6RL series are **single-phase hybrid inverters** designed for installations that aim not only to feed energy into the grid but also to provide genuine backup power. What sets them apart is their **fast switching to backup mode** and solutions facilitating integration into the home - from managing smart loads to working with generators or microinverters. Two independent **MPPTs** allow flexible design of PV strings on different rooftop sections or under partial shading conditions, resulting in more stable operation and better yields. High **European efficiency** means lower losses under typical operating conditions, leading to more usable energy annually. Monitoring can be conveniently done via WiFi or Ethernet, and popular communication interfaces are also available. MG5RL/MG6RL offer broad compatibility with energy storage systems, and robust safety features (including AFCI) along with the declared manufacturer warranty enhance investment security - both for homes and small commercial applications. ## Questions ### How quickly does the Sungrow MG5RL/MG6RL switch to backup power during a grid outage? The switchover to backup mode takes less than 4 milliseconds, making the transition virtually imperceptible to connected devices. Computers, routers, and household appliances equipped with switch-mode power supplies continue operating without resetting. In addition, the inverter supports 200% peak backup power output for up to 10 seconds, enabling smooth startup of high-inrush loads such as pump motors and air-conditioning compressors powered from the energy storage system. ### Is the Sungrow MG5RL/MG6RL suitable for a roof with two separate roof sections or under partial shading conditions? Yes. The unit features two independent MPPT inputs with a voltage range of 40-425 V and a maximum string current of 20 A per input, allowing panels installed on two different roof sections or at different orientations to be connected as separate strings. Each MPPT tracker independently follows its own maximum power point, so shading of one group of panels-by a chimney or dormer windows, for example-does not reduce the energy yield of the remaining string. ### What does the 97.6% European efficiency rating of the Sungrow MG6RL mean, and why does it matter? European efficiency is a weighted average that accounts for the varying load levels characteristic of Central European climates, including overcast mornings and fluctuating irradiance. It describes real-world conversion losses more accurately than peak efficiency measured under ideal laboratory conditions. A rating of 97.6% means that over the course of a year only a minimal fraction of the energy generated is lost in the DC-to-AC conversion process, which directly translates into higher savings on electricity bills and an improved LCOE for the overall system. ### Which energy storage systems are compatible with the Sungrow MG5RL/MG6RL series? The series is compatible with more than 50 certified third-party energy storage systems, giving installers and end users significant flexibility when selecting a battery without being locked into the Sungrow ecosystem. For those who prefer a single-brand solution, Sungrow's own MGL060 battery is also available. It is based on LFP cells with a capacity of 314 Ah, a rated cycle life of 8,000 cycles, and a guaranteed end-of-life capacity retention of 60%. ### Can the Sungrow MG5RL/MG6RL operate alongside a generator and microinverters within the same installation? Yes. The MG5RL/MG6RL series is designed with flexible multi-source energy integration in mind. It supports a generator input as a backup source during extended grid outages combined with low solar irradiance, while simultaneously operating in parallel with microinverters already connected to the installation. The intelligent load management function further allows critical loads to be prioritized, ensuring that essential circuits receive power preferentially under constrained generation conditions. ### What fire-protection features does the Sungrow MG5RL/MG6RL inverter include? The inverter incorporates a built-in AFCI (Arc Fault Circuit Interrupter) module that detects electrical arcing in the DC wiring-one of the leading causes of fires in photovoltaic installations. The device responds automatically by isolating the affected circuit before ignition can occur. This is complemented by an IP65 ingress protection rating and a C5 anti-corrosion class, which together protect the internal electronics against harsh environmental conditions throughout the system's service life. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/inverters/ds-20250731-mg5rl-mg6rl-datasheet-v2-en-sea-mea-be281b90a06e.pdf) ## Alternatives | Inverter | Rated AC | Euro efficiency | MPPT | Weight | Difference | | --- | --- | --- | --- | --- | --- | | [SolarEdge StorEdge AC Coupled Single Phase Inverter (HD‑Wave) – SE5000H / H5000SE](https://comparepv.com/inverter/solaredge-storedge-ac-coupled-single-phase-inverter-hd-wave-se5000h-h5000se) | 5 kW | 99.0% | | 9.0 kg | +2.3 pp efficiency, 9.0 kg lighter | | [SolarEdge SE5000H](https://comparepv.com/inverter/solaredge-se5000h) | 5 kW | 99.0% | | 12.0 kg | +2.3 pp efficiency, 6.0 kg lighter | | [Huawei SUN2000L-5KTL](https://comparepv.com/inverter/huawei-sun2000l-5ktl) | 5 kW | 98.0% | 2 | 10.6 kg | +1.3 pp efficiency, 7.4 kg lighter | | [Growatt MOD 5000TL3-HU](https://comparepv.com/inverter/growatt-mod-5000tl3-hu) | 5 kW | 97.8% | 2 | 19.0 kg | +1.1 pp efficiency, 1.0 kg heavier | | [Huawei SUN2000-5KTL-L1](https://comparepv.com/inverter/huawei-sun2000-5ktl-l1) | 5 kW | 97.8% | 2 | 12.0 kg | +1.1 pp efficiency, 6.0 kg lighter | | [Ginlong Solis RHI-3P5K-HVES-5G](https://comparepv.com/inverter/ginlong-solis-rhi-3p5k-hves-5g) | 5 kW | 97.7% | 2 | 25.1 kg | +1.0 pp efficiency, 7.1 kg heavier | | [Growatt SPM 5000TL-HU](https://comparepv.com/inverter/growatt-spm-5000tl-hu) | 5 kW | 97.6% | 2 | 26.0 kg | +0.9 pp efficiency, 8.0 kg heavier | | [Growatt MOD 5000TL3-XH](https://comparepv.com/inverter/growatt-mod-5000tl3-xh) | 5 kW | 97.5% | 2 | 12.5 kg | +0.8 pp efficiency, 5.5 kg lighter | --- Source: https://comparepv.com/inverter/sungrow-mg5rl
