Kstar unveils 1,100 V string inverters

• The Chinese manufacturer has developed the brand-new products for the C&I solar sector. They are available in two versions, with 121 kW and 150 kW of AC output as well as effectiveness ratings varying from 98.7% to 99.0%.

Shenzhen Kstar Science and also Technology has introduced KSG-150UM/ KSG-120CL, a new line of 1,100 V string inverters for industrial and commercial applications.

There are two versions of the item, with 121 kW and 150 kW of AC result and also effectiveness rankings varying from 98.7% to 99.0%. The European efficiency ratings for the two variations are 98.3% and 98.5%.

The inverters step 1,055 x 700 x 336 mm, with the 150 kW variation weighing 110 kg and the 121 kW device coming in at 96 kg. They have 12 optimal power point tracking (MPPT) networks and 24 string inputs. MPPT voltage ranges from 200 V to 1,000 V, while the MPPT performance purportedly stands at 99.9%. The inverters have an ambient operating temperature ranging from -25 C to 60 C.

Kstar states the gadgets feature an energetic arcing security function that can accurately detect arc mistakes as well as require the inverters to shut down within 2.5 seconds. The Chinese inverter vendor stated the new products likewise include a built-in PID recuperation module and also an anti-PID component that can avoid potential induced deterioration (PID).

"To assure greater reliability, the inverter is outfitted with high accuracy RCD protection circuit, which aids to safeguard individual safety," Kstar claimed.

The inverters depend on an innovative monitoring & O&M system to streamline maintenance job. "Moreover, IP66 security as well as C5 deterioration protection layout warranty that the inverter is run under almost all environment problems," the supplier said.

Kstar has been offering the brand-new products throughout the globe considering that the start of this month. It also just recently introduced a 1,500 V string inverter, an all-in-one residential battery inverter solution, as well as a brand-new inverter series for roof PV ranges.
