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.

IMPORTANT:
This document provides instructions for installation, setup, and
operation of the product. These instructions are for use by
qualifi ed personnel who meet all local and governmental code
requirements for licensing and training for the installation of
electrical power systems with AC and DC voltage up to 600 volts.
Failure to install or use this equipment as instructed in the
literature can result in damage to the equipment that may not
be covered under the limited warranty. This product is only
serviceable by qualifi ed personnel.
NOTES:
For programming and full functionality, this product requires
the use of an OutBack Power system display such as the
MATE3s. It is intended to monitor systems with OutBack
Power inverters, charge controllers, and related products.
This document assumes knowledge of features, functions,
and operation of other OutBack Power products. Consult
appropriate literature as necessary.

One of the primary benefi ts of the FLEXnet DC is its ability to accurately monitor a battery bank’s state of Float Stage charge (SOC). While voltage gives an approximation of SOC, this is only accurate if the battery has stabilized in a resting state for a period of several hours at room temperature.
