Lithium Iron Solar Battery



COMPANY OVERVIEW:    The Iron Edison Lithium Iron Battery is the newest technology in energy storage batteries.  Fully compatible with industry-leading inverters and charge controllers, Iron Edison’s Lithium Iron Batteries offer the safest, simplest and most dependable energy storage solution for off-grid and grid tied battery backup applications.

THE IRON EDISON BATTERY:  Assembled in Denver, CO, Iron Edison Lithium Iron Batteries are a complete energy storage system. The integrated Battery Management System (BMS) monitors & regulates each cell in the battery bank to provide perfectly balanced charging and discharging while guarding against over charge, over discharge and thermal overrun situations. Internal DC disconnects provide battery protection and isolation. The entire battery system is contained in a rugged metal enclosure.

BATTERY LIFE: Supporting a daily 70% depth of discharge, Iron Edison Lithium Iron Batteries should last 15 years or more (5,500 cycles), and comes with a 10 year warranty.

INVERTER CHARGER BMS COMPATIBILITY:  The Iron Edison Lithium Iron Battery is designed to be fully compatible with industry leading inverters and charge controllers like Schneider, Outback, Magnum, MidNite Solar and SMA. Unlike the Tesla PowerWall, Iron Edison’s LiFePO4 battery comes in industry standard 48 volt configurations making it a direct replacement for lead acid battery chemistries.
