Kstar launches 1,500 V string inverter

• The transformer-free 250 kW product uses a reported efficiency of 99%, offering a European ranking of 98.5%.

Chinese inverter maker Shenzhen Kstar Science as well as Technology has actually revealed KSG-200UH/ KSG-250UH, a 1,500 V string inverter for large-scale applications.

The transformer-free 250 kW inverter supplies a reported efficiency of 99%, for a European rating of 98.5%. It gauges 1,055 x 700 x 336 mm, considers 110 kg, and has 12 optimal power point monitoring (MPPT) channels and also 24 string inputs. MPPT voltage varies from 600 V to 1,500 V. The inverter has an ambient operating temperature ranging from -25 C to 60 C.

The producer declares that the tool is equipped with an arcing security function that can precisely spot arc mistakes, safeguarded by inverter closures within 2.5 seconds. The inverter additionally includes a potential-induced destruction (PID) recuperation feature to make sure far better efficiency of the modules.

" The anti-PID module shifts the PV possibility to ground over absolutely no as well as prevents PID effect," the firm described. "The high precision RCD security circuit helps to safeguard personal safety and security."

It included that its IP66 defense and C5 rust defense layout permit the inverter to operate in bad environmental conditions. "The size of the item and also efficiency guarantee depends upon a job's size and also attributes," it added.
