Product Description
The BYD Chess C15 (model OSN-P120B274-U) is an outdoor-rated battery energy storage system built on BYD's LFP (lithium iron phosphate) cell platform with forced-air cooling, packaged in an enclosure of approximately 160 x 190 x 230 cm designed for exterior installation. It targets commercial and industrial sites that need storage capacity outdoors — freeing indoor floor space — with weather-resistant construction matched to pad-mount deployment.
Forced-air cooling keeps the LFP cell banks within their optimal temperature window without the plumbing complexity of liquid systems, simplifying installation and maintenance at outdoor sites. The Chess platform is available in prebuilt ESS + inverter configurations, streamlining project engineering for behind-the-meter applications like peak shaving, backup, and solar self-consumption.
