Kehua's new PV project in the land of folk songs is put into operation


Name50MW PV Project in Zuoquan County



LocationZuoquan County, China

Engineer Zhang has recently been hearing a lot of Shanxi folk songs with a melodious tune, which is an unusual experience for him. He learned from a customer that this is the national intangible cultural heritage "Zuoquan Folk Song". He was responsible for the delivery of inverters for a 50MW project in Zuoquan County, the home of Chinese folk culture. We should build a better ecological environment for this culturally rich county and nourish the land with green power.


This 50MW PV project is located in Zuoquan County, Jinzhong City, Shanxi Province. This PV plant uses all 650W Type 210 modules and every power generation unit uses smart on-grid string inverter SPI250K-B-H and supporting equipment from Kehua Digital Energy. A total of 200 string inverters of the same type are installed in the station to efficiently convert the DC power from the PV modules into 800Vac output power and connect it to the sub-array substation, which will continuously feed the green power into the grid through voltage boosting. This is another successful application of Kehua Digital Energy inverters adapted to 210 type high power modules in mountain PV projects.


Kehua's SPI250K-B-H string inverter is equipped with 18 DC inputs, each DC input supports a high current of 20A and is highly adaptable to 210 modules. The string inverter solution with multiple MPPT is suitable for mountainous PV plant construction scenarios, effectively reducing the power generation loss caused by DC side mismatch, effectively increasing the power generation during the operation cycle of the plant and improving the overall profitability of the customer.

The 50MW PV power generation project in Zuoquan County can provide about 80 million kWh of clean electricity per year, meeting the electricity demand of about 50,000 households, which is equivalent to saving nearly 30,000 tons of standard coal consumption and reducing about 60,000 tons of air pollutants such as sulphur dioxide, nitrogen oxides and soot, with good economic and energy-saving benefits.
