China’s Deye has developed a new lithium iron phosphate battery system with a nominal voltage of 51.2 V. According to it, up to 32 modules with a capacity of 6.14 kWh can be stacked and connected in parallel, giving a total capacity of 196.48 kWh.
“The RW M6.1 series is especially suitable for applications with high power, limited installation space, limited load capacity and long service life,” the manufacturer said.
Up to 32 battery modules can be connected in parallel, with a capacity of 6.14 kWh to 196.48 kWh. The nominal voltage of one module is 51.2 V, dimensions 460 mm x 720 mm x 143 mm and weight 55 kg. It is suitable for wall or floor installation and has a depth of 160 mm with a hanging board.
“The low-voltage battery is a backup energy source for household power application,” Deye stated. “The high-capacity storage is designed to offer homeowners the opportunity to maximize self-consumption of solar energy, by reducing the power coming into the grid and increasing the excess power generated by the battery and solar energy.”
The new battery discharges at ambient temperatures between -20 C and 55 C and charges at temperatures between 0 C and 55 C. It has a 10-year warranty and is said to have a lifespan of over 6,000 cycles.
The new product is IP65 rated and approved according to UL 1973, IEC 62619 and UN 38.3 certificates.
