The Ginlong Solis S6-GC3P-NV-ND series comprises three-phase grid-tie inverters designed for commercial and industrial applications, where reliable performance, design flexibility, and easy energy production monitoring are essential. Thanks to multiple MPPT (depending on the power version), the inverter efficiently manages different module strings, facilitating system design with multiple roof orientations or partial shading-each string can operate at its own maximum power point.
The transformerless topology and high European efficiency translate to significantly better yields in typical operating conditions in Poland, not just in the lab. In practice, this means fewer losses and more energy fed into the grid over the year.
The inverter offers comprehensive communication and monitoring options (including WLAN, Bluetooth, and RS485) along with integration with a remote monitoring platform, simplifying service and diagnostics. This model is not a hybrid inverter, so it does not directly work with energy storage systems. The series meets grid connection requirements and features an IP66 protection class, making it suitable for outdoor installation.

Pros and cons
The S6-GC3P(40-60)K-NV-ND model achieves a maximum efficiency of 98.6%, while the 25-36 kW versions achieve 98.5%. For comparison, the SMA Sunny Tripower CORE1 achieves 98.5%, and the Fronius Symo Gen24 Plus achieves 98.4%, placing the Solis series among the top performers in the commercial three-phase inverter market without the need for a premium brand surcharge.
The NV (Natural Ventilation) designation indicates the absence of mechanical fans - the only moving parts are eliminated. This results in a higher estimated MTBF (Mean Time Between Failures), no risk of fan failure after several years of operation, and noise levels close to 0 dB(A), which is important when installing in buildings with office spaces.
Depending on the power variant, the series offers 4 or 5 independent MPPTs (data from ENF Solar / solisinverters.com), which allows for the use of multiple orientations and strings with different angles without the need for dedicated optimizers. In a typical commercial rooftop installation with a multi-faceted roof, this eliminates the need for additional per-string devices.
The IP66 sealing class allows for outdoor installation without the need for additional enclosures (reducing CAPEX). At the same time, Ginlong Solis maintains its BNEF Tier 1 bankable status since 2023 and is the 3rd largest inverter manufacturer in the world (according to VP Solar / BNEF 2023 data), which makes it easier for financing institutions to fund projects with this bankable manufacturer.
The series combines WLAN, Bluetooth, and RS485 in a single device, enabling wireless commissioning (via Bluetooth), integration with SCADA/BMS systems via RS485 (Modbus RTU), and remote cloud monitoring via LAN/WLAN - these three independent communication paths reduce the risk of losing telemetry data in the event of failure of a single channel.
The "ND" (No Display) designation indicates the absence of a local LCD/OLED screen. During startup and diagnostics in the field, connection via a mobile app (Bluetooth) or a laptop (RS485/Wi-Fi) is required, which increases the commissioning time compared to models with a display (e.g., SMA or Fronius with an integrated HMI). In installations with limited Wi-Fi range, this can be inconvenient.
