This allows for lossless operation of three different roof orientations (e.g., east-south-west) or independent shading management without the need for power optimizers. - **Maximum efficiency of 98%** - The peak efficiency of 98% declared by the manufacturer places this series at the top of the ranking for single-phase inverters in the 7-10 kW class. This directly translates to a higher annual energy yield, particularly during peak generation hours in the Polish climate. - **Integrated AFCI protection** - The built-in DC arc-fault circuit interrupter (AFCI) meets safety standards without the need to purchase external protective modules. In Poland, AFCI protection has become a requirement for residential building installations, as mandated by insurance companies since 2023. - **IP66 protection class** - Full protection against dust and strong water streams allows for outdoor installation without the need for an additional enclosure, which is standard in Polish prosumer installations exposed to variable weather conditions. - **Tier-1 BNEF manufacturer, ranked among the top 3 globally** - Ginlong Solis maintains Tier-1 BloombergNEF status (verified in Q1 2025) and is ranked as the 3rd largest manufacturer of photovoltaic inverters globally. This status directly impacts the bankability of the project and ensures long-term service availability, typically over a 10-15-year operational period. ### Cons - **Lack of hybrid functionality (without a battery pack).** - The series is exclusively grid-tied - it does not directly support any energy storage systems. In the Polish prosumer market, where net billing has significantly reduced the profitability of exporting since 2022, the lack of native integration with a battery means that a separate hybrid inverter will be required when expanding the installation to include a battery. - **Communication via WiFi/LAN requires a separate recording device.** - Unlike Huawei SUN2000 (with built-in Wi-Fi + 4G) or SolarEdge (with integrated monitoring), the S6-GR1P K03 NV ND series does not have a built-in communication module. Remote monitoring requires the purchase and installation of a separate data logger, which adds to the overall cost and introduces a potential point of failure in the installation. ## About this series The Ginlong Solis S6-GR1P K03 NV ND is a single-phase grid-tie inverter designed for residential and commercial installations, especially where roof complexity requires flexibility. Its main advantage is the **3 MPPT design**, enabling independent power tracking for three strings simultaneously. This facilitates easier optimization of energy yield during partial shading and across different roof orientations (e.g., east-south-west) without compromising string selection. High **European efficiency** ensures the inverter maintains good performance not only at peak conditions but also in typical operating conditions in Poland, leading to more stable energy production throughout the day. Practical features include **integrated AFCI protection** for enhanced DC safety and comprehensive grid protection. Remote monitoring is available via the **data logger and app**, with communication options depending on configuration (e.g., Wi-Fi or wired). This series is ideal for demanding residential and small commercial installations; it is not a hybrid inverter and is therefore not designed for direct use with energy storage systems. ## Questions ### Is the Solis S6-GR1P K03 NV ND inverter suitable for a roof with roof sections facing different directions? Yes, this is one of the greatest strengths of this series. Thanks to three independent MPPT inputs, you can connect three separate strings of panels oriented, for example, east, south, and west. Each channel tracks maximum power independently, so different orientations and varying tilt angles of the roof sections do not cause mutual energy losses. This makes it an ideal solution for typical dual- and triple-pitch roofs. ### What is the warranty on the Solis S6-GR1P K03 NV ND inverter? The standard manufacturer's warranty on Solis S6 series inverters is 10 years, with the option to extend it to 15 or even 20 years upon device registration. Ginlong Solis is a Tier 1 manufacturer, and the operational lifespan of the unit is estimated at approximately 20 years, confirmed by independent DNV-GL testing. The exact warranty terms should be verified with the distributor in your region. ### What is AFCI in the Solis S6-GR1P K03 NV ND inverter and is it really necessary? AFCI (Arc Fault Circuit Interruption) is a built-in function for detecting arc faults on the DC side of the system, i.e., within the panel circuit. An electrical arc at a damaged connector or along the cables may be invisible to the naked eye while simultaneously posing a serious fire hazard. In this series, the AFCI protection operates internally within the inverter, eliminating the need to purchase a separate device and enhancing the safety of the entire installation. ### How does system monitoring work with the Solis S6-GR1P K03 NV ND inverter? Monitoring is provided through the SolisCloud platform and a dedicated mobile application available for Android and iOS. The inverter supports Bluetooth communication (for configuration via smartphone) as well as connectivity through an external data logger with Wi-Fi or LAN. The application displays current and historical production data, daily and annual yield figures, and real-time device status accessible from anywhere. ### Can the Solis S6-GR1P K03 NV ND be integrated with an energy storage system (battery)? No. The S6-GR1P K03 NV ND series is a grid-tie inverter, not a hybrid inverter. It does not have a battery input or energy storage management functionality. If you are planning an installation with a battery, you will need a hybrid inverter from the Solis EH series or another model dedicated to storage applications. This inverter is, however, an excellent choice for a conventional prosumer installation without a battery. ### What power range does the Solis S6-GR1P K03 NV ND series offer and what type of installations is it designed for? The series includes models rated at 7, 8, 9, and 10 kW, making it suitable for single-family homes with higher energy demand as well as small commercial facilities. The inverter weighs approximately 16 kg, carries an IP66 protection rating, and operates in temperatures ranging from -25 °C to +60 °C. It supports next-generation 182/210 mm panels with an input current of up to 20 A per string, ensuring compatibility with modern high-power modules. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/inverters/solis-datasheet-s6-gr1p-7-10-k03-nv-nd-phl-v2-2-202412-25ec15d915c0.pdf) ## Alternatives | Inverter | Rated AC | Euro efficiency | MPPT | Weight | Difference | | --- | --- | --- | --- | --- | --- | | [Growatt MOD 8000TL3-X](https://comparepv.com/inverter/growatt-mod-8000tl3-x) | 8 kW | 98.1% | 2 | 14.0 kg | +1.0 pp efficiency, -1 MPPT, 2.1 kg lighter | | [Growatt MOD 8KTL3-X2(Pro)](https://comparepv.com/inverter/growatt-mod-8ktl3-x2-pro) | 8 kW | 98.1% | 2 | 14.6 kg | +1.0 pp efficiency, -1 MPPT, 1.5 kg lighter | | [Sungrow SG8.0RT-20](https://comparepv.com/inverter/sungrow-sg8-0rt-20) | 8 kW | 98.0% | 2 | 17.0 kg | +0.9 pp efficiency, -1 MPPT | | [GoodWe GW8000-DT](https://comparepv.com/inverter/goodwe-gw8000-dt) | 8 kW | 98.0% | 2 | 24.0 kg | +0.9 pp efficiency, -1 MPPT, 7.9 kg heavier | | [Ginlong Solis S6-GR3P-8K02-NV-ND](https://comparepv.com/inverter/ginlong-solis-s6-gr3p-8k02-nv-nd) | 8 kW | 97.9% | 2 | 15.4 kg | +0.8 pp efficiency, -1 MPPT | | [Sungrow SG6.0RT](https://comparepv.com/inverter/sungrow-sg6-0rt) | 8 kW | 97.8% | 2 | 18.0 kg | +0.7 pp efficiency, -1 MPPT, 1.9 kg heavier | | [Solis-3P8K-4G](https://comparepv.com/inverter/ginlong-solis-solis-3p8k-4g) | 8 kW | 97.8% | 2 | 18.0 kg | +0.7 pp efficiency, -1 MPPT, 1.9 kg heavier | | [Sungrow SG8.0RT-P2](https://comparepv.com/inverter/sungrow-sg8-0rt-p2) | 8 kW | 97.7% | 2 | 18.0 kg | +0.6 pp efficiency, -1 MPPT, 1.9 kg heavier | --- Source: https://comparepv.com/inverter/ginlong-solis-s6-gr1p8k03-nv-nd
