Low Voltage Modular Energy Storage

Product catalog summary
Overview: This document provides technical specifications for POWERSYNC Energy Solutions' low voltage modular energy storage systems, focusing on various models with different power capacities.
Performance Specifications: The document outlines the nominal voltage and capacity for each model, with energy capacities ranging from 4.8 kWh to 5.12 kWh. The chemistry used is LiFePO4 with prismatic cells, and the systems support scalability up to 62 parallel connections. The cycle life is noted as 6,000 cycles at 70% retained capacity with 80% depth of discharge (DOD) at 0.5C. The self-discharge rate is less than 1% per month, with charge efficiency at 100% and discharge efficiency over 98%.
Discharge Specifications: Maximum continuous current varies by model, with high power models supporting up to 200A. Recommended cut-off voltages and under-voltage recovery levels are specified for each model.
Charge Specifications: Maximum continuous charge currents are detailed, with recommended bulk, absorb, and float charge voltages provided. Equalization is recommended for 60 minutes every 7 days, with over-voltage recovery thresholds specified.
Mechanical Specifications: All models feature a 19” 4U stainless steel case with an IP20 protection rating. Dimensions and weights are provided for each model.
Environmental Specifications: Operating temperature ranges from -10°C to 60°C (14°F to 140°F). The systems come with a 15-year limited warranty and are certified under UL-1973, CE, IEC62619 & CB, KC BIS standards. Shipping classifications include UN3480, Class 9, UN38.3.
