Ginlong Solis S6-EH3P K10 series inverters are three-phase hybrid inverters combining grid-connected operation with genuine backup support. The switch to backup mode occurs virtually unnoticed, enabling critical circuits in homes or businesses to remain operational. Notable is the multi-string MPPT (depending on the variant), which simplifies designing rooftop systems with different orientations and minimizes losses from partial shading - each tracking string operates independently, optimizing panel yield. High European efficiency ensures stable, cost-effective energy production under typical Polish climatic conditions, not just in ideal lab settings. Remote management is convenient via SolisCloud monitoring and extensive communication options (including WiFi, Ethernet, CAN/RS485, and often Bluetooth). The series is designed for collaboration with energy storage systems (including high-voltage solutions) and complies with key connection standards and safety requirements, facilitating integration into residential and commercial installations.

Pros and cons
The S6-EH3P(75-125)K10-NV-YD-H series integrates 10 independent MPPT (Maximum Power Point Tracking) channels, supporting up to 20 PV strings (up to 21 A per string). In complex rooftop or partially shaded C&I (Commercial & Industrial) installations, each channel operates independently, minimizing mismatch losses that are not possible in solutions with 2-4 MPPT channels.
The switchover time to the backup output is less than 10 ms, which meets the requirements of VFI-class UPS systems according to IEC 62040-3 for most sensitive electronic devices and industrial control systems. Competitive C&I hybrid systems without a dedicated backup path typically achieve switchover times of 20-50 ms.
Models with power ratings of 75-100 kW can handle short-term overloads of up to 2.0 times the rated power on the backup port, while models with a rating of 125 kW can handle up to 1.6 times the rated power. This allows for the starting of electric motors and compressors without the need for a separate starter unit - a significant advantage in industrial and agricultural applications.
The master-slave architecture allows for the creation of a system up to 750 kW using inverters from the same series without a central controller. This provides a flexible scaling option for commercial facilities that are growing gradually, which is not available in many competing C&I products in this power range.
Ginlong (Solis) is recognized as a bankable manufacturer by BloombergNEF (Tier 1 list, starting Q4 2023), and holds the 3rd position globally in terms of PV inverter sales volume. This translates into long-term manufacturer warranties and service availability in the Polish market.
The NV designation indicates operation exclusively with high-voltage energy storage systems (typically 200-800 V DC). This excludes compatibility with popular 48 V LV systems (e.g., Pylontech US series), which can limit battery selection and potentially increase the overall cost of the storage system compared to a similar S6-EH3P K02-NV-YD-L variant that supports low voltage.
