Enersys SuperSafe SBS EON 100F Hybrid Applications Operation Guide

Product Overview

The SuperSafe SBS EON Technology batteries are designed for high-performance in demanding hybrid and off-grid applications. These batteries excel in environments where mains power is unavailable and reliance on diesel generators, wind turbines, or PV arrays is necessary. They are engineered to handle regular cyclic duty, typically one cycle per day, and offer improved endurance at elevated temperatures.

Operating Conditions

The recommended operating temperature range is -40°C to +50°C, with optimal performance achieved at +20°C. It is critical to ensure that the battery temperature never exceeds +50°C during operation, as this will significantly reduce service life. The system supports two primary operating modes: Controlled Full State of Charge and Controlled Partial State of Charge (PSoC). In PSoC mode, the battery is deliberately operated at a partial charge to maximize expenditure savings, provided it is periodically returned to a full state of charge.

Charging and Commissioning

Prior to initial use, a commissioning charge of 24 hours at 2.40Vpc with no load is required. For cyclic applications, fast charging is recommended with rectifier output set between 2.35 and 2.40Vpc at 20°C. Because these batteries have very low internal resistance, they accept high charge currents; the minimum recommended current is the load plus 0.1C10 Amps. When using time-based recharge methods, temperature compensation must be applied to the charge voltage to ensure longevity.

Discharge and Maintenance

To prevent abusive over-discharge, discharge should be stopped when the voltage reaches the configured depth of discharge. For a 48V system, this typically involves a partial load disconnect at 47V and a low voltage disconnect at 46.3V. Regular data logging is essential for warranty validation. Users should record commission charges, cycle counts, depth of discharge, charge/discharge durations, and temperature history. Batteries must be stored in a cool environment, as higher temperatures increase self-discharge rates. When the open circuit voltage approaches 2.10 Volts/cell, a freshening charge is mandatory.

Disposal

SuperSafe SBS EON batteries are fully recyclable. At the end of their service life, they must be handled, packaged, and transported in accordance with local and national regulations by a licensed battery recycler.
