The Ginlong Solis S6-EH3P-K-H series is a hybrid three-phase inverter designed for installations where self-consumption, flexible energy management, and readiness to work with storage are equally important. This solution proves its worth both in modern homes and smaller commercial properties - anywhere daily consumption patterns change and energy should be shifted to the evening.
A major feature is the multi-string MPPT, which facilitates designing systems with modules on different rooftop sections or with partial shading - the inverter precisely "collects" energy from independent PV string sections. In practice, this translates to more stable yields.
High European efficiency means truly better production under typical operating conditions, not just in an ideal laboratory point. Plus, monitoring via SolisCloud and communication options, including WiFi and Ethernet, simplify remote service. The series supports HV energy storage, offers export control functions and operates with robust insulation class, backed by reliability common to this class of equipment.

Specifications
Pros and cons
The S6-EH3P-K-H series offers 4 independent MPPT trackers that can handle 8 strings (with 20 A each in 12-20 kW variants), which exceeds the typical 2 MPPT configuration used by Fronius GEN24 Plus in this power class. This results in: better energy optimization in complex roof configurations, with different panel orientations, and under partial shading.
The declared maximum efficiency of 97.7% places this series among the top three-phase hybrid systems commercially available. For comparison, the Huawei SUN2000-12/15/20KTL-M2 achieves 98.6%, while Fronius GEN24 models in this class reach 97.8%. The values are similar, but the Solis S6 does not lag behind Tier 1 competitors.
Full protection against dust and strong water streams allows for installation outdoors (facade, garage, unconditioned boiler room) without the need for additional enclosures. This is a practical advantage over IP65 inverters, especially in industrial installations with high levels of dust.
The backup output supports a 1.6x surge capacity (UPS-level switching) for 10 seconds, ensuring the smooth startup of devices with high inrush currents, such as pumps, air conditioners, and compressors. The switching time to backup mode is at UPS level, which reduces the risk of resetting sensitive devices.
The built-in ability to connect up to 6 inverters in parallel allows for scaling the installation up to approximately 300 kW (6 × 50 kW) without changing the control system architecture. This is a significant advantage in smaller commercial buildings, where demand may increase after expansion.
The official compatibility list includes, among others, BYD, Dyness, BMZ, Ampace, BSLBATT, and dozens of other high-voltage battery storage brands. This provides investors with the real flexibility to choose a battery storage system, regardless of current prices and market availability, without being dependent on a single battery supplier.
Solis accounts for approximately 7% of the market share in commercial-scale PV project valuations, compared to Huawei's ~39% and a significantly stronger presence of SMA/Fronius in the premium EU segment (data: Elum Energy, 2025). This translates to a smaller number of certified service technicians in Poland and a potentially longer response time in case of failures outside of the largest urban areas.
