Its CSA listing covers wall-mounted, permanently connected installation. The DC input accepts up to 1500 V and uses MC4 connectors. The 255K models connect to an 800 V three-phase grid, and the 185K and 125K-PLUS models connect to 600 V, all at 60 Hz. Maximum efficiency is 98.6 to 99.0 percent depending on the model, and the CEC efficiency is 98.3 percent. Communication is over RS485, with PLC as an option, and the unit has a two-line LCD display. The 185K and 255K models have integrated PID recovery.
