Application
Commercial Rooftops Solution
● For commercial centers, large shopping malls, industrial campuses, and other buildings and places with concentrated electricity usage, since the price of commercial use electricity is usually high, PV power stations can be valuable. However, these types of rooftops are usually distributed widely, are complex, and the space in the power distribution room may be insufficient, making it difficult to construct a power station.
● These types of power stations usually only release the unused portion of electricity back to the grid which will be 380V, and is similar to home use electricity. Inverter type is generally chosen depending on power station capacity and distribution conditions.
● Recommended indoor product: central 100-500kW inverter
● Recommended outdoor products: series SPI20K-B2, SPI30K-B2, SPI50K-B
