BSP is the official sizing engine for EnerSys. This standard is a method for defining DC loads and sizing lead-acid batteries. Before we start, the following are the two different load types in a substation: Continuous loads: loads that normally operate continuously. Battery Sizing The battery capacity for a PV system can be calculated using the following formula: Capacity (AH) = Total Daily Load x Days of Autonomy x Design Factor The Design Factor The nominal battery load should be adjusted for ageing and operating temperature conditions. Lead Acid Temperature correction factor applied at the end of the calculation. Our scope of work often extends from layout, base and detailed designs to grounding, control, protection and DesignTech provides Substation design as a major and unique design service. There have been several developments in substation equipment technology that can have an impact on battery size requirements.
