Delta Calms 140-kVA Solar Inverters – Electronics Weekly
The integrated design combines string fuses, surge protection and DC switching in one unit in an aluminum housing with protection class IP65.
"Gen2 offers the same maximum performance as its predecessor, but now works with a quieter level of 71.5 dB (A) and still offers a peak efficiency of 99.1%," says the company, which combines natural convection with intelligent active ventilation uses. The Euro efficiency is 98.7%, the sound power is measured at 1 m and 25 ° C.
The M125HV Gen2 accepts a maximum of input voltages between 860 and 1,500 VDC
sporadic voltage of 1,600V. For example, up to 20 strings can be connected via Amphenol connectors, e.g.
Part of utility-scale ground-mounted systems, Delta said. "By accepting high input voltages, the inverter can reduce the number of power cables to be transported, allowing installers to use smaller gauge cables and minimize energy losses."
