1500V is definitely one of the hottest topics in the energy storage industry. Because of its significant "cost reduction and efficiency increase", high voltage has become the technological direction of many energy storage companies. There are three advantages of high-voltage system: first, it corresponds to the 1500V photovoltaic system; second, the system energy density and energy conversion efficiency will be greatly improved; third, the system integration cost, container, line loss, land occupation and construction cost will be greatly reduced.
As a professional provider of energy storage converters in China, Nebulas has previously made a technical layout for 1500V energy storage converters and established a project to develop a 1.5MW energy storage converter.
There are more characteristics than high efficiency and energy saving for Nebula 1.5MW intelligent converter: the conversion efficiency is as high as 99% by using multi-level technology; connected to the grid with sine-ware current with harmonic content less than 3%; Optional online/ offline network working mode; DSP full digital vector control; advanced IGBT power devices ensuring strong reliability; perfect protection function; automatic control of battery pack charge and discharge with a wide DC voltage input range of 1000-1500V, which improves system efficiency; Standard communication interface (RS485, CAN, Ethernet), convenient for remote monitoring.
