Times of 1500V PV System has Come

The comparably high cost has been the main barrier to mass deployment of PV markets. How to reduce the cost and improve the efficiency becomes what counts most. 1500V PV power system takes the place of 1000V lowering the cost from design. This paper will show advantages and challenges of 1500V PV power system from three aspects and introduce a solution from MORNSUN with 1500V input PVxx-29Bxx series power supply. The power supply takes power directly from the 1500V high voltage end for monitoring the PV system circuit, simplifying the design of PV system circuit to reduce costs of system manufacturing and maintenance when compared with AC power or battery power and enhance comprehensive benefits of PV power generation system itself. This power supply also provides multiple protection functions that improve system safety when a breakdown occurs and further enhance the safety of power supply and its load safety.
