    Our Energy Storage Solutions:  Assembled in Denver, CO, Iron Edison Lithium Iron Phosphate Batteries are a complete energy storage system. The integrated Battery Management System (BMS) monitors and 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 lithium iron solar battery system is contained in a rugged metal enclosure.

    FEATURES: Lithium Iron solar batteries have all the advantages of modern power storage. A Lithium Iron battery’s electrochemical capacity allows it to store more energy than lead acid. If you’re looking for energy storage for your residential solar panels and UPS systems, lithium batteries are your best options. Furthermore, due to its chemical composition, we’re able to design smaller but more efficient batteries.

    SAFETY: Lithium Iron batteries have superior chemical and thermal stability than other Lithium-ion batteries. It remains cool at room temperature while Lithium-ion heats up faster and may suffer thermal runaway under similar charging conditions.

    LEAD ACID REPLACEMENT: As solar energy becomes a popular power source, lithium solar batteries will become the standard option for manufacturers and installers. Replacing your lead-acid batteries with lithium iron is a step in the right direction. As such, if you switch solar panel systems, your Iron Edison Lithium Iron Phosphate Batteries will still be useful. We have lithium batteries at 48v, with capacities up to 5,600 Ah.

    BATTERY LIFE: Supporting a daily 80% depth of discharge, Iron Edison Lithium Iron Batteries should last 16 years or more (6,000 cycles), and comes with a 10 year warranty.
