Overview

The OutBack Power FLEXnet DC (FN-DC) is an advanced multi-channel DC system monitor designed for battery-based renewable energy systems. Through the OutBack MATE/MATE2 interface, it provides real-time and historical insight into battery state-of-charge, energy production, energy consumption, and system efficiency. With configurable shunt-based measurements, 128 days of data logging, and an integrated magnetic-latching AUX relay, the FN-DC improves system performance, reduces generator runtime, and helps extend battery life. :contentReference[oaicite:1]{index=1}

Key Features

  • Real-time DC monitoring: Tracks system production, consumption, and battery charge/discharge flow. :contentReference[oaicite:2]{index=2}
  • 128-day history logging: Stores daily production, consumption, and minimum SOC for long-term trend analysis. :contentReference[oaicite:3]{index=3}
  • Three configurable shunt channels: Each channel supports loads or sources up to ±1000 A DC. :contentReference[oaicite:4]{index=4}
  • Accurate battery state-of-charge: Displays SOC in 1% increments with multi-mode summary screens. :contentReference[oaicite:5]{index=5}
