5.3 Integration with Lynx Distribution System

The Lynx Smart BMS NG is designed for modular integration with other Lynx products to create a comprehensive power distribution system.

This image depicts a family enjoying an off-grid setup with solar panels, illustrating how the Lynx Smart BMS NG can be seamlessly integrated into various power systems for scalability and long-term performance.

Lynx Distributor

The Lynx Distributor module is a central power distribution hub within the modular Lynx Distribution System. It features a positive busbar with four fuse-protected connections, each with an LED indicator for fuse status. Fuse status can also be monitored when connected to a Lynx Shunt or Lynx Smart BMS. The negative busbar provides four connections and a ground connection.

Lynx Power In

The Lynx Power In module connects batteries to the rest of your DC system, organizing wiring and power distribution. It includes positive and negative busbars with four connection points for batteries, chargers, or DC loads, and a ground connection.

Lynx Shunt VE.Can

The Lynx Shunt VE.Can module is a component of the modular Lynx Distribution System. It includes positive and negative busbars rated up to 1000A, a built-in battery monitor, and a holder for the main system fuse (fuse not included). It communicates with GX devices via VE.Can.

Lynx Class-T Power In

The Lynx Class-T Power In module connects and fuses up to two strings of Lithium batteries. It features positive and negative busbars and connections for two Class-T fuses, along with a ground connection for the DC system. Class-T fuses (225A, 250A, 350A, 400A) must be purchased separately.
