Additional Data:
The system will be powered by 12 Vdc, 110 Wp PV module
System voltage = 24V
Inverter efficiency = 85%,
Maximum Depth of Discharge (MDoD) =80%
Days of Autonomy = 3 days
Battery rating = 12V, 100 Ah
Temperature derating factor = 1 - 0.0044 x (system temperature)
Battery efficiency = 80%
Average temperature in the location is 40 °C.
Sun hours at the location = 9 hours
Consider a safety factor of 30% in inverter sizing.
