The Ginlong Solis S6-GC3P K07-ND series are three-phase grid-tie inverters designed for large commercial and industrial installations, where high yield and fast diagnostics are crucial. What sets them apart is their 7 independent MPPTs, offering great design flexibility - making it easier to connect panels with different orientations, string lengths, and minimizing losses from partial shading or uneven soiling.
Their high European efficiency reflects real-world performance better than the maximum efficiency alone, tailored to typical loads and sunlight variability in Poland. The series features advanced safety functions, including AFCI arc fault detection and intelligent string monitoring with I-V curve scanning, facilitating maintenance without on-site visits.
Convenient communication options (including Bluetooth and WLAN) and remote firmware updates are available for operational oversight. The IP66-rated enclosure performs well in demanding environments, and the equipment is ready for integration with C&I energy management systems.

Pros and cons
Each of the 7 independent MPPT inputs supports a current of up to 54A, allowing for the direct connection of both bifacial and large-format (182/210 mm) modules without derating. A DC/AC ratio exceeding 150% maximizes energy yield under the variable solar irradiation typical of Poland.
The European efficiency rating of 98.3% places the series among the top performers in 150-200 kW C&I inverters, reflecting real energy losses under partial loads and varying sunlight conditions more accurately than peak efficiency alone. This translates to a higher annual kWh yield in a moderate climate.
Built-in arc fault detection (AFCI) and intelligent scanning of the I-V curve for each string enable remote diagnostics and fault localization without the need for on-site service visits. For large C&I installations, this translates to lower O&M costs and reduced MTTR (mean time to repair).
Ginlong Solis maintains Tier 1 status according to BloombergNEF, confirmed again in Q1 2025. As the third-largest manufacturer of PV inverters globally, the brand is recognized by financing institutions for C&I projects as being bankable, which simplifies obtaining financing and insurance for installations.
The Night Defense (ND) mode maintains full monitoring and security system activity 24/7, eliminating the need for additional power supplies for the security systems. Over-the-air (OTA) software updates via Bluetooth/WLAN reduce the number of service visits throughout the device's lifespan.
The standard warranty period is 5 years - an extension to 10 years is available for an additional cost. For large C&I projects financed by banks or infrastructure funds that typically require a 10-year manufacturer warranty as a financing condition, this represents an additional cost in the project budget. For comparison, some competitors (e.g., SMA on certain models) offer a 10-year warranty as standard.
The ND function draws a small amount of power (~tens of watts) from the grid at night to maintain active monitoring. Contracts with PPA agreements that charge for each kWh drawn from the grid, or installations with zero-import restrictions, may require additional documentation and agreements with the grid operator.
