Iron Edison releases NEW Lithium Battery Line, 4LiFe

Iron Edison is proud to introduce its NEWEST lithium battery for solar, the 4LiFe Lithium Ion Battery. The 4LiFe Lithium Battery can be used as a direct replacement for lead acid batteries. The 4LiFe Battery is designed to simplify battery installation with it's plug-and-play design. The 4LiFe battery can add battery to an existing solar installation, and can be used for a new off-grid or grid-tied solar system coupled with energy storage.

What makes these batteries great is the variety of sizes available. The 4LiFe battery starts at 100Ah at 48 Volts (4.8kWh), and is also available in 200Ah 48 Volts (9.6kWh) and 300Ah 48 Volts (14.4kWh). Unlike the LG RESU battery, the 4LiFe battery can operate in parallel from two to twenty units to achieve up to 6,000Ah at 48 Volts - that's 288kWh of energy storage!

The 4LiFe batteries come with an integrated battery management system, that allows the battery to charge and discharge at a super fast rate. Iron Edison's 4LiFe lithium battery utilizes the safest type of lithium-ion chemistry, Lithium Iron Phosphate (LiFePO4). Lithium Iron Phosphate batteries are the safest and most stable of the Lithium battery chemistry types, making it ideal for residential use.

The Iron Edison 4LiFe batteries can be used in commercial solar applications, residential solar with battery, boats, and RV's. The 4LiFe lithium batteries from Iron Edison are compatible with all industry-leading inverters and charge controllers such as Schneider Electric, Outback Power, Magnum Energy, MidNite Solar and SMA. This helps solar installers to save time hunting for compatible parts, giving them a faster and more convenient installation experience. From a practical perspective, the 4LiFe batteries are lightweight (about 1/2 the weight of lead acid) and can be easily moved around.

This Iron Edison 4LiFe battery has an expected cycle life of 7500+ cycles at 80% depth of discharge. Like all other Iron Edison batteries, the 4LiFe lithium battery also comes with a 10 year warranty, and lifetime technical support. Unlike the Tesla Powerwall, which requires an Internet connection to qualify for warranty coverage, the Iron Edison 4LiFe battery can provide energy security without online monitoring.
