For comparison, the EU efficiency of comparable Sungrow SG50CX models is approximately 98.2%, which translates to a realistically higher annual yield under the Polish solar irradiation profile. - **5-6 independent MPPT - flexible string design** - The use of 5 or 6 independent maximum power point trackers (MPPTs) allows for connecting strings with different orientations, inclines, and lengths without significant losses due to mismatch. In practice, when installing on complex, multi-tiered industrial roofs (with varying orientations), this provides a clear advantage over inverters with 3-4 MPPTs. - **AFCI + monitoring of the I-V curve according to the standard** - The built-in arc fault detection (AFC) function reduces the fire risk on the DC side - a requirement that insurers are increasingly enforcing in commercial buildings. Analyzing the I-V curve for each string allows for remote detection of degradation or damage to modules without the need for on-site service visits, which shortens the mean time to repair (MTTR). - **A Tier-1 bank that has been financially stable since 2005.** - Ginlong Solis maintains Tier-1 bankability status according to BNEF rankings (H1 2024, H1 2025), meaning that financing projects with these inverters does not require additional security from project banks. The company has been operating since 2005 and has its own R&D center and European service (UK, DE), which reduces the risk of component availability over a 10-15 year period. - **Scalable up to 6 MW within a single network** - The Solis (50-60)K series inverters support parallel connections up to 6 MW using a shared RS485 bus and a single SolisCloud account. This simplifies the management of large rooftop systems (e.g., a 1-4 MW rooftop farm) without the need for additional data concentrators. ### Cons - **Older generation (S5/4G) vs. the current S6** - The Solis (50-60)K series is based on the S5 (or earlier 4G) platform, while the currently produced S6-GC series offers an MPPT input current of up to 20 A (compared to approximately 12.5 A in the S5), which is significant when working with modern 580-700 Wp bifacial modules. For new projects, this may mean the need to use a larger number of parallel strings and additional fuses. - **Standard EU warranty: 5 years** - Ginlong Solis offers a standard 5-year warranty in Europe (with the option to extend it for an additional fee). Fronius and SMA offer extensions up to 10 years through a simplified online procedure, while Huawei SUN2000 offers a standard 5-year warranty with flexible extension options. For projects financed through project finance, an expensive insurance policy covering the missing period may be required. ## About this series The Ginlong Solis Solis-(50-60)K series are three-phase grid-tie inverters designed for commercial and industrial applications, where stable operation, flexible string configurations, and fast diagnostics are essential. The use of multiple MPPT (5 or 6) facilitates optimizing energy yields from panels with different orientations, uneven sun exposure, and partial shading-without overcompromising string selection. In practice, high European Efficiency means fewer losses in real operating conditions, leading to better energy production in Poland’s typical daily profile, not just in the lab. Safety features, such as AFCI, help reduce the risk of DC-side fire hazards, while intelligent string monitoring with I-V curve analysis shortens service time. Remote management is handled by the SolisCloud platform, featuring communication including RS485 and optionally via WiFi/GPRS, depending on the configuration. This makes it an excellent choice for companies, warehouses, halls, and rooftop solar farms, where monitoring export power, robust casing, and a reliable manufacturer’s warranty are crucial. ## Questions ### What MPPT (Maximum Power Point Tracking) does the Solis inverter (50-60V) have, and is it sufficient for a large system with multiple connections? The Solis (50-60)K series offers 5 or 6 independent MPPT inputs, supporting a total of 10 or 12 strings. This allows for the connection of panels with different roof orientations or different inclines without losing efficiency due to mismatch. For rooftop solar farms, sheds, and warehouses, where multiple roof sections are common, this configuration eliminates the need to install optimizers on each module. ### What is the warranty on the Solis (50-60)K inverter, and is it possible to extend it? The standard manufacturer's warranty is 5 years. Ginlong Solis allows for the purchase of an extended warranty within 12 months of purchase: for periods of 10, 12, or even 15 years in total. For commercial installations, where the inverter operates continuously for many years, it is advisable to consider the extended warranty option when signing the contract with the installer, as the cost of replacing a 50-60 kW device is significant. ### Does the Solis (50-60)K inverter have an integrated AFCI (Arc Fault Circuit Interrupter) for protection against fire caused by electrical arcs? Yes, the Solis (50-60)K series is equipped with an AFCI (Arc Fault Circuit Interrupter) function, which detects dangerous electrical arcs on the DC side and automatically shuts off the circuit. This is important in industrial and rooftop installations, where long DC cable runs increase the risk of mechanical damage. AFCI is increasingly required by insurers and is becoming a standard in commercial projects. ### What is the efficiency of a Solis (50-60)K system, and what does this mean for energy production in Poland? The maximum efficiency of the inverter reaches 98.7%, and the high European efficiency translates into tangible savings in the Polish climate, where it operates at partial loads for most of the year, rather than at full capacity. The higher the European efficiency, the less energy is lost as heat throughout the year, which, in a 50-60 kW installation, results in a noticeable difference in electricity bills for both purchased and consumed energy. ### How can I remotely monitor a Solis (50-60)K inverter, and does this require any additional equipment? The platform, SolisCloud, is used for remote monitoring and is accessible via a web browser and a mobile app. Communication is based on RS485 (Modbus), and an additional data logger, such as a WiFi or GPRS module, is required for internet connectivity. The platform allows for real-time monitoring of production, remote software updates, and analysis of the I-V curve for each string, which speeds up fault diagnosis without requiring on-site service personnel. ### Which type of installation is best suited for the Solis (50-60) inverters, and would it be suitable for a small manufacturing facility? The Solis (50-60)K series is designed for commercial and industrial applications: manufacturing halls, logistics warehouses, shopping centers, and rooftop solar farms with power ranging from several tens to hundreds of kWp, when multiple devices are combined. Its robust enclosure, power export control functionality, and RS485 industrial communication make it a good choice wherever integration with a BMS or a bidirectional meter is required. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/inverters/5f59c1f3ee3fd-fcc4f9c99af9.pdf) ## Alternatives | Inverter | Rated AC | Euro efficiency | MPPT | Weight | Difference | | --- | --- | --- | --- | --- | --- | | [Huawei SUN2000-60KTL-M0](https://comparepv.com/inverter/huawei-sun2000-60ktl-m0) | 60 kW | 98.7% | 6 | 74.0 kg | +2 MPPT, 11.0 kg heavier | | [Sungrow SG60KTL-182](https://comparepv.com/inverter/sungrow-sg60ktl-182) | 60 kW | 98.7% | 1 | 60.0 kg | -3 MPPT, 3.0 kg lighter | | [GoodWe GW60KN-MT](https://comparepv.com/inverter/goodwe-gw60kn-mt) | 60 kW | 98.5% | 4 | 64.0 kg | 1.0 kg heavier | | [Growatt MAX 60KTL3 LV](https://comparepv.com/inverter/growatt-max-60ktl3-lv) | 60 kW | 98.4% | | 82.0 kg | 19.0 kg heavier | | [SOFAR 60000TL](https://comparepv.com/inverter/sofar-solar-sofar-60000tl) | 60 kW | 98.4% | 3 | 70.0 kg | -1 MPPT, 7.0 kg heavier | | [GoodWe GW60KBF-MT](https://comparepv.com/inverter/goodwe-gw60kbf-mt) | 60 kW | 98.3% | 4 | 65.0 kg | 2.0 kg heavier | | [Ginlong Solis S5-GC60K](https://comparepv.com/inverter/ginlong-solis-s5-gc60k) | 60 kW | 98.3% | | 53.7 kg | 9.3 kg lighter | | [Ginlong Solis S6-GC60K-LV](https://comparepv.com/inverter/ginlong-solis-s6-gc60k-lv) | 60 kW | 98.3% | | 93.0 kg | 30.0 kg heavier | --- Source: https://comparepv.com/inverter/ginlong-solis-solis-60k-4g
