The Ginlong Solis Solis-5G-PRO series are three-phase grid-tie inverters designed for commercial and industrial installations, where reliable operation, safety, and easy energy management are paramount. This series stands out among C&I solutions thanks to its multi-string MPPT, which simplifies PV string design on rooftops with different orientations and helps minimize losses during partial shading or varied roof pitches.
In practice, its high European efficiency means more energy delivered to the grid under real climatic conditions, not just in the lab - translating to better investment profitability. Additionally, O&M features such as intelligent string monitoring and remote diagnostics streamline maintenance.
During daily operation, SolisCloud monitoring and flexible communication (WiFi and wired solutions depending on configuration) facilitate integration with building automation systems. The series supports modern safety features, including arc flash detection (AFCI), and the standard warranty for grid-tie inverters in Europe is 5 years.

Pros and cons
The 100K and 110K models feature 8 MPPT trackers with a maximum current of 18A per string, which allows for the connection of high-power bifacial modules (>600 Wp) without stringing them in pairs. In practice, this translates to greater flexibility in designing rooftop C&I installations with different roof orientations and reduces losses due to partial shading.
The maximum efficiency of 98.5% (models 80-110 kW), confirmed in 2024 datasheets, places the series in the top quartile of three-phase C&I inverters. The IP66 enclosure provides complete protection against dust and water ingress, which is essential when mounting on industrial roofs without additional enclosures.
Ginlong Solis has maintained its BloombergNEF Tier 1 status since Q4 2023 (reconfirmed in Q1 2025), which makes it easier for banks and infrastructure funds to finance projects. As the world's third-largest manufacturer of PV inverters (with its own production line and listed on the GPW in Shanghai), it meets the due diligence requirements of most project financing institutions.
The standard integrated arc fault detection (AFC) function, along with intelligent I/V curve scanning at the string level, allows for remote identification of faults (poor connections, damaged modules) without the need for a service visit. This reduces MTTR and lowers O&M costs in installations greater than 500 kWp, where the cost of a single service visit in Poland ranges from 800 to 1,500 zł.
The factory-supplied DC/AC ratio support up to 150% allows for the design of larger PV arrays using the same inverter, which reduces the unit installation cost (more kWh per the same CAPEX on the inverter). This is particularly beneficial in industrial installations with a fixed power consumption, where clipping is acceptable.
The datasheet for the 80-110K-5G-PRO models explicitly indicates a "without AC circuit breaker" configuration, which means that an external circuit breaker must be installed by the installer on the AC side. This results in an additional BOS (approximately 300-800 zł per device, depending on the rated current), as well as the requirement for space in the distribution panel, which complicates projects in tight industrial distribution panels.
The standard 5-year warranty aligns with the median of the segment (Huawei SUN2000, GoodWe MT), but is lower than Fronius Tauro's (7 years standard) or SMA Sunny Tripower CORE2's (5 years with the option to extend to 20 years with service packages). Extending the warranty for 80-110K-5G-PRO models to 10 years requires purchasing a separate option (approximately 512 EUR net, according to EU 2024 distributor pricing), which should be factored into the total cost of ownership (TCO) calculations for projects with a lifespan of >10 years.
