Detailed description

The MASTERVOLT MLI Ultra Connection Kit 24 V (225-400 Amp), part number 79007724, is an integration solution specifically designed to optimize the installation of MASTERVOLT MLI Ultra 24/5500 lithium batteries. This kit allows safe, efficient, and compact assembly of all required safety accessories directly above the battery, reducing clutter and wiring complexity.

Integration and Technical Performance

This connection kit includes a 24 V DC 500 A safety relay and a T-type fuse holder designed to accommodate class T fuses from 225 to 400 A (the fuse is not included and must be ordered separately based on the application). It guarantees a continuous current rating of 300 A with an overload capacity of 400 A for 5 minutes (with a 400 A fuse). The maximum supported voltage is 64 V, providing a significant safety margin. Designed for demanding marine environments, the kit operates across an extended temperature range from -25 °C to 50 °C (-13 to 122 °F).

Design and Compatibility

The MLI Ultra Connection Kit 24 V is pre-assembled on an easy-to-install mounting bracket, ensuring a perfect fit with MLI Ultra 24/5500 batteries. Installation is quick and does not require complex power tools for basic steps. The kit includes the mounting bracket, safety relay, T-type fuse holder, and two conductive bus bars. Adding this kit increases the total height of the MLI Ultra battery by 65 mm (2.5 inches) and its total weight by 2 kg (4.4 lbs). CE certified under directives 2014/30/EU (EMC) and 2011/65/EU (RoHS), it meets standards EN 61000-6-3 and EN 61000-6-2. Unlike generic solutions requiring the purchase and integration of separate components (as may be seen with brands like Victron Energy or Blue Sea for custom installations), this MASTERVOLT kit provides a turnkey solution optimized for its batteries, ensuring maximum compatibility and performance without compromise.
