• Solar Inverter
• Industrial Storage

LW 51.2100

Feature of LiFePO4 Battery

• Longer Cycle Life: Offers up to 10 times longer cycle life and 5 times longer float/calendar life than lead acid battery, helping to minimize replacement cost and reduce total cost of ownership
• Higher Power: Delivers twice power of lead acid battery, even high discharge rate, while maintain high energy capacity
• High depth of DOD: Charge & discharge at 100% DOD with high performance
• No Memory Effect: Support unstable partial state of charge (UPSOC) (charge/discharge) utilization
• Built-in safety mechanism to protect assets against any abnormal conditions (Grounding damage, surge, deep drain etc.)

Functions of Battery

• OVP, UVP, OTP, OCP, SCP
• Self-management on charging and discharging, single cell balancing function
• Supports communication with equipment over RS485
• Intelligent design, supports battery upgrade over RS232
• LCD displays battery information
