InstaGen BMS for 5kWh Battery V2

The InstaGen BMS for 5kWh Battery V2 is an advanced Battery Management System integrated into the V2 battery modules, providing intelligent monitoring, protection, and communication for safe and optimal LiFePO4 battery operation.

Product Description

This embedded BMS delivers cell-level monitoring and control for the 5kWh V2 battery modules, ensuring balanced charging, thermal management, and fault protection. It communicates via CAN bus with InstaGen hybrid inverters for seamless system integration and real-time status reporting.

Key Features

• Cell-level monitoring: Individual voltage, temperature, and SoC tracking for 16S LiFePO4 configuration.
• Active balancing: Automatic cell equalisation during charge/discharge cycles.
• Multi-protection: Over/under-voltage, overcurrent, short-circuit, and over-temperature safeguards.
• Current sharing: Ensures even distribution across parallel modules in stack configuration.
• CAN communication: High-speed protocol for inverter integration and stack coordination.
• Real-time diagnostics: Fault codes and status available via inverter monitoring platform.
