SmartBank is available in 2 different flavours. Both are relay based, intelligent, split charge controllers. SmartBank Standard is the self contained unit taking care of all your split charge needs, whatever the charge source. When installed in conjunction with the SmartGauge battery monitor, the SmartGauge operates as a full remote display along with emergency battery paralleling and comprehensive error reporting. SmartBank Advanced is the slave operated split charge device which performs the same functions as SmartBank Standard, plus more, and operates as a remote slave device controlled by the SmartGauge battery monitor.
