Batteries – Energy Storage for Solar and Off-Grid Systems

Batteries store electrical energy for use when solar production is unavailable or during grid outages. LiFePO4 batteries for solar systems (Lithium Iron Phosphate) chemistry, offering superior performance, safety, and longevity compared to traditional lead-acid batteries. Quality batteries deliver thousands of charge cycles with minimal capacity degradation, making them essential components for reliable solar and backup power systems.

The battery selection includes server rack, wall mount, and outdoor configurations across various capacities and voltages. Server rack batteries provide modular solutions that scale from single units to large banks, while wall mount options offer space-efficient installations for residential applications. Battery capacity is measured in amp-hours (Ah) and kilowatt-hours (kWh), determining how much energy can be stored and delivered to loads.

Key battery specifications include voltage (12V, 24V, 48V), DOD (Depth of Discharge) ratings, cycle life expectations, and BMS (Battery Management System) features. Advanced BMS technology monitors cell health, manages charging parameters, and provides safety protection against over-temperature, over-current, and voltage irregularities. Batteries integrate with inverters and charge controllers to create complete energy storage solutions for grid-tied backup and off-grid independence.
