Product Summary:
The 288V52Ah battery energy storage system is composed of six 48V52Ah LiFePO4 battery modules and a high voltage controller. The Sunpack 3U 48V52Ah Energy Storage Battery Modules are housed in a 19-inch cabinet for optimal space utilization and improved energy density. The standardized cabinet format makes it highly compatible with various professional applications, such as telecom base staions, UPS backup systems, small and medium commercial and industrial.
Sunpack Systems has devoted extensive effort in selecting and evaluating only the highest quality Lithium Iron Phosphate cells for incorporation into our products. By doing so, we have ensured that our products offer not only exceptional performance but also an extended lifespan that will continue to meet and exceed the demands of our customers. It should be noted that Lithium Iron Phosphate (LFP) has emerged as the best solution for energy storage due to its remarkable durability, superb safety record and technological superiority as compared to other technologies currently available in the market.
High voltage system – Designed to lower current levels, resulting in minimized energy losses during the charge and discharge cycles. This in turn makes it more efficient and responsive.
Long Cycle Life – Adopting Grade A LiFePO4 batteries with a lifespan of more than 6000 cycles, withstanding industrial-grade applications for a period of over 10 years.
Good compatibility – Standard communication protocol features compatibility with the most popular hybrid and off-grid inverters in the market, using both CAN and RS485 interfaces.
