Battery Monitoring System

Enerbatt 3G extends battery life thanks to its unique built-in function of voltage equalizer. The wireless communication between the batteries and the receiver truly simplifies the installation and the maintenance of the blocks. Thanks to the RS485 communication between the RF receiver and the touch screen, it’s adapted for installation in very wide plants.

Battery Voltage Equalizer

Equalizes battery charge end voltage at battery level to prevent overcharging and guarantee best battery use and life. With battery equalizer function activated, each battery block voltage remains close to the ideal value. Each battery works in the best condition possible so life span is maximized.
