Description
The MG LFP 24V 304 is a high capacity third generation Lithium Iron Phosphate module for marine and off-grid energy storage. It delivers 304 Ah and 7.8 kWh at 25.6 V nominal in a 54 kg metal enclosure, with an integrated slave BMS monitoring every cell voltage and temperature. Certified to IEC-EN 62619 and 62620 and approved under ES-TRIN, it is rated for more than 4000 cycles at 80 percent depth of discharge for long service life in professional systems.
Like the rest of the LFP 24V series it is fully scalable. Connect up to 4 modules in series for a 96 Vdc bank and add parallel strings, up to 96 modules, to reach capacities above 1 MWh. A galvanically isolated CAN-Bus over RJ45 links each module to an MG Master LV 24-48V, LV 72-96V or Master HV controller, sharing data with chargers, inverters and MFD displays for plug-and-play commissioning and protection.
