At 98.7%, this maximum efficiency rating is at the top of its class. 

    As part of its fifth generation, Solis also provides onboard diagnostic tools that can be used on-site or remotely, greatly reducing O&M time and cost. Further setting Solis apart from its competition, our conservative engineering design margin ensures reliable operation in the most challenging grid conditions.

    The Solis cost and energy yield advantages are unique in the industry. In combining our high cost-performance ratio, low installation and O&M costs with market-leading conversion efficiency and energy harvest advantages, the Solis 110kW technology boosts energy yield and ROI for PV power plants. 


    Industry-Leading Efficiency Delivers Lower LCOE Over The Life of The Project

    Solis 110kW boasts a staggering efficiency of 98.7%, making it one of the most efficient on the market. thanks to the Solis 110kW uses advanced insulated-gate bipolar transistors (IGBTs), and new technologies such as adaptive parallel technology and wave-by-wave current limiting protection, Making it achieves low “on resistance”, resulting in the highest efficiency and the lowest minimal losses.  

    Moreover, Solis 110kW also combines 90 MPPTs / MW, resulting in high power tracking density. With a 150% DC/AC ratio, Solis 110kW boosts energy density to ensure higher earnings and lower LCOE design. The system can produce more stable power output under irradiation, these characteristics bring nearly 3.5% power generation increase during the whole life cycle of the project.

    Superior Reliability with Top-of-Range Lifespan Results Mean Better Bankability

    Solis string inverter technologies have achieved top-of-range lifespan that have been validated by independent labs. This means solid returns you can bank on:

    • End-to-end manufacturing since 2008 with 4GW capacity in the field
    • World-class R&D facility with state-of-the-art automation verified through rigorous testing 
    • Industry-first in-house SMT circuit board production self-inspection process line ensures guarantees quality and seamless product innovation.
    • Superior QC with end-to-end control across the entire value chain
    • MTBF component performance equates to long life
    • Full in-house production ensures quality along with 100% burn-in (full power @45C) for higher confidence of field performance

    Designed for Flexibility & Higher Energy Yield

    The Solis 110kW has a flexible design that allows for shorter strings where needed and multi-orientation designs. Our multiple MPPTs are 100% fully independent, offering a wide DC operating voltage range. This means we have a higher production yield for greater roof utility and energy density.

    Furthermore, the operating mode of Solis 110kW allows the inverter to ride through grid disturbances to increase the overall system yield. Its operation-through-voltage fluctuations provide grid stability and reliability.

    Higher System Returns

    At 13 amps per string, the Solis 110kW offers one of the highest input current ratings on the market. This design allows the use of higher current bi-facial modules and can be combined with a whole column of tracking motors, which delivers more yield than current inverter designs based on lower input current. 

    Reduced O&M – Running Advanced Diagnostics On or Offsite

    Inverters are becoming increasingly more intelligent to better respond to system performance issues. As such, Solis 110kW offers advanced I-V curve diagnostic technology and string-level monitoring capabilities to improve O&M efficiency and lower O&M costs. 

    Solis 110kW incorporates on-board diagnostic tools to decrease O&M time and available web-based, remote data monitoring to respond and resolve issues more quickly. Our string-level monitoring and intelligent IV curve diagnosis functions are integrated into Ginong’s intelligent cloud monitoring platform, allowing O&M diagnostics to be completed within just 5 minutes. This allows plant managers to quickly monitor, locate and report on system faults, making O&M more digital, more efficient, and less costly.

    Because our DC connectors are integrated into the inverter, Solis 110kW substantially reduces installation time. Furthermore, our fuse-less design means less maintenance, while our high current inputs allow the combination of two strings using Y connectors. 

    Solis 110kW gives contractors more for less: less manpower; less hassle; less cost. Our swap-out replacement process is fast and efficient for simple better O&M.  


    Powerline Communications Capabilities

    The 110kW inverter communication supports optional PLC. This means an additional communication cable is not required, which saves both time and money for installers.

    Reduced Self-Generated Errors

    Large PV systems are built with numerous panels, and each panel has its own set of unique characteristics. As a result, working with different panel manufacturers increases the risks of errors. Solis created a unique leakage current suppression technology through long-term PV power station data collection and technology development. This technology not only suppresses the impact of the PV system leakage current, it also reduces the number of erroneous errors, or “false alarms”, and significantly improves the stability of PV systems.

    Reduced Effects of Inverter Output Resonance

    Solis uses the “intelligent reconstruction” algorithm technology, which reduces the effect of high capacitive or inductive hardware to achieve a large-capacity square matrix resonance suppression function. Our advanced anti-resonance technology helps to increase more accurate readings and reduce inter-plant inverter interface, reducing downtime and increasing yield.


    In addition to Ginlong’s efficiency and reliability leadership, and the technological advantages described in previous sections, Solis 110kW offers these benefits:

    Safety – In the PV industry, fire is one of the most considerable – yet least discussed risks, particularly for rooftop applications. The Solis 110kW can identify faults in the arc current while monitoring the PV model to inverse a fire at the input of the transformer. In the event of an arc fire, Solis 110kW will cut off the circuit immediately to avoid nearly 99% of the fire risk. 

    Solis110kW has a “Class I” AC lightning protection rating, which means it discharges current when it reaches 100 ~ 200k. This allows Solis to provide superior protection to C&I roofs, large wastelands, coastal and mountainous regions, and others environments that experience with frequent lightning.

    Reliability – Solis’ fifth generation technology platform has a replaceable AC/DC Type II surge protection device. This design provides a Level-1 lightning protection feature for surge-prone areas to protect the inverter from force majeure incidents, increasing system reliability in areas prone to thunderstorms and other climatic events.

    Reliability and Efficiency – the Solis 110kW adopts intelligent redundant air cooling, which not only improves the inverter’s cooling efficiency, but also greatly extends the life of the cooling fan, lowering O&M costs.
