In installations on the roofs of warehouses or office buildings with different orientations or uneven shading, each string can operate at its optimal power point, rather than reducing the overall system's output - a key advantage in the C&I (Commercial and Industrial) segment. - **High efficiency, up to 98.6-98.8%** - The maximum efficiency specified by the manufacturer is 98.6-98.8%, placing the series in the top quartile of 25-40 kW commercial three-phase inverters. The high European efficiency (taking into account variable solar conditions) directly translates to a higher annual energy yield in central European conditions. - **IP66 and AFCI compliant** - The IP66 protection class safeguards electronics against dust and powerful water jets, which is crucial when installing equipment on the roofs of industrial and warehouse buildings. The integrated AFCI (DC arc fault detection) system meets the increasing safety requirements for commercial buildings. - **DC/AC ratio >170% and support for 182/210 mm modules** - The inverter supports a DC/AC ratio above 170%, which allows for flexible design of the PV array using modern, high-power modules (182 mm and 210 mm formats). This enables maximizing energy production during peak hours without over-sizing the AC side of the inverter. - **Tier-1 BNEF ranking and position as the 3rd largest global producer** - Ginlong (Solis) is listed on BloombergNEF's Tier 1 PV Inverter Manufacturers list (since Q4 2023) and is the third-largest photovoltaic inverter manufacturer in the world. The Tier 1 status facilitates investment financing and meeting the requirements for bankability in commercial projects in Poland. ### Cons - **No built-in display (ND designation)** - The "ND" (No Display) suffix indicates the absence of a local LCD panel. Reading operating parameters on-site requires a connection to an external datalogger (e.g., a Wi-Fi/LAN module) or the SolisCloud mobile app - this can be a limitation during quick on-site troubleshooting without internet access. ## About this series Ginlong Solis S6-GC3P K03-NV-ND is a three-phase grid-tie inverter designed for small and medium-sized commercial installations - where high energy production, predictable performance, and fast diagnostics matter. The K03 variant features **3 independent MPPTs**, facilitating string design for various roof orientations, uneven soiling, or partial shading - each tracker can operate optimally, rather than pulling down the entire system. In practice, this translates to more stable yields in typical conditions for warehouse roofs, office buildings, and service facilities. The series also benefits from **high European efficiency**, meaning real performance in varying operating conditions, ensuring more energy from modules goes into the grid annually. Additionally, **smart monitoring and O&M tools** are available, including diagnostic functions and remote monitoring via the SolisCloud platform, as well as communication through standard interfaces (e.g., RS485, WLAN, Bluetooth). The IP66-rated enclosure and security set facilitate safe operation in demanding environments, while available certifications and warranty terms support formalities for investments in Poland. ## Questions ### Which types of installations are suitable for the Solis S6-GC3P K03-NV-ND series? The S6-GC3P K03-NV-ND series are three-phase grid-tie inverters designed for small to medium-sized commercial installations with a power rating of 25-36 kW. They are suitable for rooftops of factories, offices, and service buildings, where stable operation, high energy production, and easy remote monitoring are required. The inverter does not support energy storage - it is solely a grid-tie device that operates in conjunction with the electrical grid. ### What does the K03 designation mean in the name of the Solis S6-GC3P inverter? The K03 letter indicates that the inverter has 3 independent MPPT (Maximum Power Point Tracker) controllers. This allows each string of panels to operate at its optimal power point independently of the others. In practice, this means better performance on multi-pitched roofs, with modules oriented in different directions, or with partial shading, as a less sunlit string does not reduce the performance of the others. ### What is the warranty on the Solis S6-GC3P K03-NV-ND inverter? The standard Solis warranty is 5 years from the date of purchase. During this period, the manufacturer provides free repair or replacement of the device. The warranty can be extended up to 12 months from the purchase date, for a total of 10, 12, or 15 years, by purchasing the appropriate extended protection package. To maintain the warranty, the device must be installed by a qualified person and registered on the SolisCloud platform. ### What is the efficiency of the Solis S6-GC3P K03-NV-ND inverter, and what voltage range does it operate in? The S6-GC3P K03-NV-ND series achieves European efficiency levels of approximately 98.5%, which translates to a genuinely high level of efficiency under varying solar irradiation conditions throughout the year. The DC input voltage range is 180-1100 V, allowing for flexible string design and compatibility with modern 182 mm and 210 mm modules. The AC output voltage is 3/N/PE 230 V / 400 V. ### How to monitor the performance of the Solis S6-GC3P K03-NV-ND inverter? The inverter is standardly equipped with RS485 interfaces, enabling connection to local energy management systems. Remote monitoring is performed through the SolisCloud platform, accessible via a web browser and a mobile app. Optionally, a Wi-Fi or GPRS module can be added. The platform allows for viewing current production, historical data, diagnostics, and alerts for failures - which significantly simplifies the maintenance and billing of the system. ### Is Ginlong Solis a reputable inverter manufacturer, and is it worth trusting them? Ginlong (Solis) Technologies is a Chinese manufacturer with over 20 years of experience, classified as Tier 1 by the BloombergNEF agency, indicating proven financial and technological stability. The company holds certifications required in the European market, including NC RfG, and its inverters are distributed and serviced in Poland by authorized partners. The Tier 1 status is particularly important for projects financed by banks or through leasing agreements. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/inverters/1249119200691d201bb88de-9847e062cc64.pdf) ## Alternatives | Inverter | Rated AC | Euro efficiency | MPPT | Weight | Difference | | --- | --- | --- | --- | --- | --- | | [Growatt MID 25KTL3-X2 (Pro.E)](https://comparepv.com/inverter/growatt-mid-25ktl3-x2-pro-e) | 25 kW | 98.6% | 3 | 24.0 kg | +0.6 pp efficiency, 1.3 kg lighter | | [Growatt MID 25KTL3-X](https://comparepv.com/inverter/growatt-mid-25ktl3-x) | 25 kW | 98.6% | 2 | 23.0 kg | +0.6 pp efficiency, -1 MPPT, 2.3 kg lighter | | [Growatt MID 25KTL3-X1](https://comparepv.com/inverter/growatt-mid-25ktl3-x1) | 25 kW | 98.5% | | 29.5 kg | +0.5 pp efficiency, 4.2 kg heavier | | [GoodWe GW25K-MT](https://comparepv.com/inverter/goodwe-gw25k-mt) | 25 kW | 98.4% | | 40.0 kg | +0.4 pp efficiency, 14.7 kg heavier | | [Fronius Verto 25.0 400](https://comparepv.com/inverter/fronius-international-fronius-verto-25-0-400) | 25 kW | 98.3% | 4 | 35.2 kg | +0.3 pp efficiency, +1 MPPT, 9.9 kg heavier | | [Sungrow SG25T-P2-CN](https://comparepv.com/inverter/sungrow-sg25t-p2-cn) | 25 kW | 98.3% | 2 | 19.0 kg | -1 MPPT, 6.3 kg lighter | | [Huawei SUN2000-25KTL-M5](https://comparepv.com/inverter/huawei-sun2000-25ktl-m5) | 25 kW | 98.2% | 2 | 21.0 kg | -1 MPPT, 4.3 kg lighter | | [SOFAR 25KTLX-G3](https://comparepv.com/inverter/sofar-solar-sofar-25ktlx-g3) | 25 kW | 98.2% | | 36.0 kg | 10.7 kg heavier | --- Source: https://comparepv.com/inverter/ginlong-solis-s6-gc3p25k03-nv-nd
