1. Delivery and Storage • 1.1 Receiving Inspection • • • • Inspect for missing components. Check against the shipping/packing documents. Inspect each package or pallet for integrity and electrolyte leakage. Record receipt date and inspection data results, and notify your servicing dealer of any damage. Take photographs if necessary. 1.2 Storage • • • • • • Store the battery in a dry, clean, ventilated, cool and frost-free location.
• be split according to the capacity or age of the batteries respectively. Note: The type of lead-acid batteries may differ between strings as long as the required charging regime and voltage (VPC) per string is guaranteed. • • • Discover Tubular Gel cells/blocks may be connected in series to increase system voltage. In the case of each series connected string, only use batteries of the same voltage, capacity, design and age.
3.1 Discharging No restriction on the discharge current up to the maximum allowable is required as long as the connections are properly sized and the battery temperature stays within the allowable limits. The Maximum Daily Depth of Discharge per cycle (MDDoD) is: • Stand-alone: 20%-25% of the batteries C10 nominal capacity rating • Hybrid systems: 50%-60% of the batteries C10 nominal capacity rating Standard RE warranty is reduced on system designs that exceed the MDDoD.
3.2.3 Normal Operation Charging 3.2.2 Equalizing Charge 3.2.2.1 Functional Equalizing To avoid permanent capacity loss and acid stratification in cycling operation the goal is to achieve a complete recharge (100% SoC) after every discharge. Capacity loss and acid stratification will threaten the battery’s state of health.
3.3 Operation at Very Low or No Load When there is little or no load connected to the system for long periods (more than 1 month) while the battery remains connected, the normal charging settings in Sec. 3.2 are too high and result in unwanted overcharging. The same applies to Stand-alone systems with oversized PV array and very low MDDoD (<5%) (e.g. remote telecom transmitters). In these circumstances use the following settings. The temperatures are average over one month.
Battery Voltage in relation to DoD as a guidance for the initial LVD settings (first-t settings) - 25ºC reference temperature 5.
Definitions & Abbreviations • • • • • • • • • • • • • Ampacity: The allowable current-carrying capacity of a conductor measured in amps. Ampacity is the current, in Amperes, that a conductor can carry continuously under the conditions of use without exceeding its temperature rating. Battery Capacity: The power a battery can deliver from full charge at standard temperature, and at a specified (usually C10) discharge rate.
