Delta’s new flagship inverter model, the 3-phase M125HV series, offers a maximum of 125kVA output power, active cooling, and industry-leading peak efficiencies of up to 99 percent. These string inverters are ideal for maximizing the return on investment from large commercial and ground-mounted photovoltaic plants with megawatt-sized solar arrays.
High-power utility-scale string inverters are currently transitioning from 1,000 volts dc to 1,500 volts dc. These new systems allow for longer strings, resulting in fewer combiner boxes, less wiring, less trenching, and significant balance of system cost savings. The new M125HV series inverters for 1,500 volts dc systems, for instance, can reduce levelised cost of electricity by enabling higher-voltage arrays, says Delta. (nhp)
