PRODUCTS Delta’s Advanced Central and String Inverters 3.75 MW 1500V DC IP65 PV Inverter Delta’s C3750 is a technologically ad- vanced, utility scale Central inverter with rated output of 3750kW comes with Delta’s cutting edge technology and reliable service support. With the smart Fan controlled Forced Air cool- ing system, the inverter can achieve absolutely no power de-rating up to 50°C ambient temperature. This also helps to provide 10% additional pow- er up to 4125kW over and above the nominal rating, up to 30°C ambient. The IP65 cabinet comes as a true Outdoor system gives higher reliabil- ity and ease of installation to the cus- tomers. This high power density inverter is compatible with maximum capac- ity (Wp) Mono-PERC and Bi-facial PV modules available currently. The built-in passive Anti-PID relay logic feature reduces the PID effects on the panels. There is no requirement of any external arrangement for auxiliary power, UPS and ducting thus reduc- ing installation overhead costs and comes as a Plug and Play design. The C3750V includes advanced grid support functions like PQ control, LVRT, and grid voltage regulations which can be parametrically set, based on the local utility requirements and comply to latest CEA 2019 guide- lines as per Indian grid code. 250kW (@50˚C) String Inverter for Utility Applications Delta’s latest advanced inverter, pow- ering new efficiencies is the New M250HV string inverter. With a max- imum output power of 250 kVA and a wider input voltage range from 550 to 1500V DC, this high-performance inverter is particularly well-suited to large, megawatt-scale ground-mount- ed solar plants. The M250HV optimiz- es electrical generation for photovol- taic systems with its peak efficiency of 99 percent. In addition, the higher input voltage results in lower current, which allows for smaller cable diame- ters and reduces energy loss during operation. The IP 66 based enclosure level protection helps a lot especially when installing in outdoor environ- ments. Furthermore, a sophisticated cooling system ensures that the operating temperatures are always within the optimum range for the electronics thus provides No de-rating power up to 50°C. A combination of natural convection and fans is used to en- sure air flow through the device, and to prevent hotspot formation inside the housing. This makes the M250HV ideal for use in areas with very high outdoor temperatures. Thanks to its compact design and low weight, the M250HV is easy to transport and in- stall. Having 12 MPP trackers, string cur- rent monitoring, I-V Curve scanning, Night time reactive power genera - tion, Anti-PID function, Modbus RS 485, Sub-1G wireless communica- tion, Y-Connector string support, Arc Fault detection, PRO EL imaging test and an electromagnetic interference (EMI)-proof design give the system planner more flexibility when design - ing PV plants and maximizing overall yields. 41 energetica INDIA- December_2020
