"I wanted to let you know I am very pleased with the service you gave & the quality & condition of the solar panels I received from EcoDirect. I will purchase more items in the future from EcoDirect and will be sure to tell others about your fine operation."

"Thanks EcoDirect! My solar system is up and running; waiting for City and San Diego Gas & Electric inspections this week; so far so good!"

My shipment arrived on time, as predicted. Very, very good performance by EcoDirect. What more could you ask for from an online material supplier? Looks like the quantity from Quick Mount is spot on & the rails were bundled safely. EcoDirect will be my recommended source to my friends & neighbors for solar.

OutBack FLEXnet DC System Monitor - FN-DC

Our Price: $264.65

Product Code: OUTBACK-FN-DC


OutBack FLEXnet DC Multichannel Advanced DC System Monitor

Manufacturer Part Number: FN-DC

FLEXnet DC monitors up to 3 shunts for improved battery management. Includes twisted pair wire and communications cable.

The FLEXNet DC collects, monitors and records time-based battery amp, watt and volt data for display on the OutBack MATE series of products, allowing for more accurate set point adjustments and precise battery recharging. Five LEDs on the FLEXnet DC act as a state-of-charge indicator bar for a quick status display. It also offers an auxiliary (AUX) relay that acts like a switch to turn on or off a user-installed light, alarm, or similar low voltage DC device. It can also be set up as a two-wire autogenerator starter.


Battery Status Screen

Easily see your system’s current condition with this at-a-glance display. This screen shows an easy to interpret “fuel gauge” style status bar, current state-of-charge and whether you are currently charging or discharging your batteries. This is useful for those system owners who want a way to quickly understand the current state of their battery bank.

Now Summary Screen

Monitor the amount of power your system is currently producing and consuming as well as the amount of power going IN and OUT of your battery bank. This screen also displays your battery bank’s voltage and current state-of-charge, providing you with real-time production monitoring of DC sources, such as a solar array or small wind turbine, as well as consumption by loads.

Today Summary Screen

Monitor the cumulative energy your system has produced and consumed as well as the total amount of energy that has gone to charging your batteries today. This screen also displays today’s lowest state-of-charge and allows you to see how your overall system production compares to system consumption.

History Summary Screen

Review historical energy production and consumption data for the most recent 128 days, including the minimum battery state-of-charge reached for each day. This screen can be used to watch power system production and consumption trends.

Detailed Description

The FLEXNet DC works in conjunction with up to three input current shunts (either a FW-SHUNT250 or FW-SHUNT500, each rated 500A/50mV) also available from OutBack. Only a single FLEXNet DC is needed for any system using OutBack components. The FLEXnet DC is not intended to be used with the MATE2M. It is designed to work with the MATE or the MATE2.


  • One shunt is included as standard equipment with each OutBack FW500-DC and FW1000-AC enclosures.
  • The shunt(s) cannot be connected to a positive (+) ground system.
