Battery size is determined by considering factors such as the power demand of the system, desired battery runtime, efficiency of the battery technology, and any specific requirements or constraints of the application. It involves calculating the required energy capacity and selecting a battery with matching specifications.
The ‘ Average Daily Load ‘ is calculated by multiplying the Adjusted Watts by the daily usage hours. Batteries for autonomous systems are dimensioned to store energy generated by the array for utilization by the system loads as needed. The overall rated battery capacity required is dependent upon the following factors:
This calculator computes the number of batteries needed for any application +/- a battery. System is set to +20% (ah X 1.2) to account for wire resistance, resulting voltage loss, heat, and other DC system inefficiencies. For Critical Applications, battery sizing should be a starting point.
