Ginlong Solis (40-60)kW / (50-70)kW-HV inverters are designed for three-phase installations, where stable operation, easy service, and flexible string design are key. The (40-60)kW variant is a grid-tie inverter for commercial and industrial projects, while the (50- 70)kW-HV is a high-voltage hybrid inverter that can work with energy storage and provide backup power and peak shaving strategies. A key advantage is the multiple MPPT channels - they allow dividing the PV generator into various rooftop sections, orientations, and partially shaded zones, improving yields without string reconfiguration. In practice, this is also helped by the high European efficiency - it means fewer losses under typical operating conditions in Poland, resulting in more energy fed to the grid or used on-site. Monitoring is based on SolisCloud and standard communication interfaces, including WiFi and Ethernet, facilitating remote diagnostics. The series offers comprehensive safety features, grid compliance, and a warranty dependent on version and market. This solution is ideal for companies, rooftop farms, and larger installations, especially those planning energy storage integration.

Pros and cons
The S6-GC3P(40-60)K-ND model offers 4-5 independent MPPT (Maximum Power Point Tracking) channels, which allows each part of the roof or shaded area to be assigned to a separate channel without any cross-channel losses. For buildings with irregular roof geometries, this translates to a significantly higher annual energy yield compared to inverters with 2-3 MPPT channels in this power class.
The declared maximum efficiency of S6 is 98.7%, which places the series above the typical median for the 40-60 kW segment (approximately 98.0-98.4% for comparable Huawei, Delta, and Growatt models). In Polish climatic conditions (many days with dispersed solar radiation), the high European efficiency directly translates to the energy balance of the installation.
Ginlong Solis is listed on the BNEF Tier 1 PV Inverter Manufacturers list (Q4 2023 and subsequent editions) and is the 3rd largest inverter manufacturer globally. For C&I projects financed with credit or leasing, this means easier acceptance by financial institutions without the need for additional technical due diligence.
The S6-EH3P series (equivalent to 50-70V K-HV) supports high-voltage batteries in the range of 150-800 V, implements peak shaving in both self-use and generator modes, and the backup port can withstand a 1.6x overload for a short period. Two independent battery ports (with a 70 A charging/discharging capacity) allow for the connection of two separate battery banks.
The S6-EH3P architecture allows for the parallel connection of up to 6 inverters, providing scalable capacity of approximately 300 kW AC with a unified control and monitoring platform in SolisCloud (WiFi, Ethernet, optionally 4G). This simplifies the expansion of the system in stages without the need to replace equipment.
The warranty period for commercial versions varies depending on the market and the specific product (there is no single, global policy). For comparison, SMA offers a standard 5-year warranty in Poland, with the option to extend it to 20 years within a clear service package. This makes it easier for banks and leasing companies to finance projects, as it requires warranty documentation for the entire loan period.
The S6-GC3P(40-60)K-ND network variant does not allow for later expansion with energy storage - it is necessary to replace the inverter with a hybrid model or install a separate AC-coupled storage system. For facilities planning to add batteries within a 3-5 year timeframe, this could generate additional costs for replacing the equipment.
