Overview Guide
FLEXnet DC Battery Monitor
Introduction
OutBack Power's FLEXnet DC (FN-DC) is a battery monitoring
device that serves as a window to the battery bank. By
tracking battery voltage and the amount of incoming and
outgoing current, the FN-DC indicates the battery bank's state of
charge (SOC) and enables users to precisely confi gure charging
parameters to maximize battery performance and lifespan.
The FN-DC also provides an auxiliary relay that can activate a
ventilation fan, low-battery warning alarm, or other low-voltage
DC device. The MATE3s can use the FN-DC's information to
stop all charging devices when the batteries are full.
