Energetica India 89 - May 2020

61 energetica INDIA- May_2020 Solis 110kW 5G Three Phase Inverter for Rooftop Solar Systems PRODUCTS The new “Solis 110kW” inverter, as the company claims, brings a more reliable, efficient and secure inverter solution to commercial rooftop appli - cations, resulting in stronger system returns and lower LCOE. The inverters feature insulated-gate bipolar transistors (IGBT), adaptive parallel technology, and wave-by- wave current-limiting protection. The Solis 110kW also combines 90 MPPTs/MWand a 150%DC/AC ratio. In addition, it has multiple MPPTs that are 100% fully independent, while of - fering a wide DC operating voltage range, according to the company. The 1099.5x567x344.5 mm trans - former-less inverter weighs 84 ki - lograms and operates at ambient temperatures ranging between -25 and 60°C. It can run at a maximum altitude of 4,000 m and has a cooling system based on intelligent redun - dant fan-cooling. The new 5G inverters utilize a new bipolar PWM control algorithm that can reduce the change rate of the common-mode voltage, while also suppressing leakage current, the company said when it launched the 5G platform. Developed for boosted perfor - mance, return, as well as O&M, item benefits consist of: Efficiency advantages increase generation by 3.5 percent during the project’s total lifecycle: • Advanced IGBTs lower “on resis - tance,” increasing efficiency and decreasing losses • 90MPPTs / MWdelivers high-pow - er tracking density • 150 percent DC/AC ratio boosts system returns (and density) Yield advantages increase rooftop utility and energy density: • The flexible design allows for shorter strings and multi-orientation designs • 100 percent fully independent multiple MPPTs provider a wide DC operating voltage range • 13 amps’/string configuration of - fers high input current ratings O&M advantages for cost-effec- tive fault monitoring, locating, and reporting: • Advanced I-V curve diagnostics and string-level monitoring improve efficiency • Integrated on-board diagnostics and cloud monitoring help resolve issues quickly • Unique leakage current suppres - sion technology increase accuracy of false alarms Features • Over 99% Max. efficiency • DC input reverse alarm • Intelligent redundant fan-cooling • Fuse free design to avoid fire hazard • Leakage current repression technology • Volt-watt work mode integrated • Optional anti-PID function integrated • Wide voltage range and low start - up voltage • 9/10 MPPT design with precise MPPT algorithm • THDi<3%, low harmonic distortion against grid • Perfect commercial site monitor- ing solution • Anti-resonance, supporting over 6MW paralleled in one transformer • Strings intelligent monitoring, Smart I-V Curve Diagnosis supported • Type II surge arrester for both DC and AC, type I surge arrestor optional • Integrated DC switches, AC switch optional
