Real-Time, Network-Accessible Battery System Insights
Ensure the optimal performance, longevity, and security of your critical battery systems with the Micro Instruments SOC Monitor with Ethernet Attachment. This robust device provides precise, real-time monitoring of your battery's State of Charge (SOC), voltage, and current, delivering the data directly to your network. Designed for seamless integration, the built-in Ethernet port allows for remote access and monitoring via SNMP, making it an essential tool for managing off-grid solar systems, industrial backup power, and marine applications.
Advanced Monitoring for Lithium Chemistries
Specifically engineered to handle the flat voltage discharge curve of LiFePO4 and other lithium batteries, this monitor goes beyond simple voltage readings. It employs a sophisticated current-counting algorithm, utilizing a non-invasive, clamp-on DC current sensor for easy installation. This method provides a far more accurate SOC percentage than relying on voltage alone, which is critical for protecting batteries that allow for a deep depth-of-discharge (DoD). The monitor is compatible with 12V, 24V, and 48V battery banks, offering wide-ranging versatility.
Key Features:
- Ethernet Connectivity: Monitor your battery's health remotely via any standard network using the SNMP protocol.
- High-Precision Monitoring: Get accurate, real-time data on State of Charge (SOC), voltage, and current flow.
- Broad Compatibility: Works with 12V, 24V, and 48V Lithium (LiFePO4) battery systems.
- Non-Invasive Sensor: Includes a contactless DC current sensor that clips around the battery wire, simplifying installation compared to traditional shunts.
- Intelligent SOC Calculation: Uses current flow, end charge voltage, and tail current parameters to accurately determine when the battery is 100% charged.
- Generator Control Relay: Features a dry-contact relay that can be configured to automatically start/stop a generator at a specific SOC percentage.
