Machine Riddle No.51 - Solar battery sizing for motor load
How should we proceed to size a  large storage battery bank  for solar power whose load contains different sizes of lamps,ac,motors etc
When sizing a diesel generator we consider starting current and voltage drop at its terminal. When voltage drops AVR & Governor act quickly to restore the voltage and frequency If power is supplied by storage batteries how should we do it. Is there any specially made battery for this application and what factors should be considered.

Ups inverter sizing should be done based on actual continuous and transient current loads. The  motor starting current and non-linear behavior of loads should be considered in inverter selection. In these cases the crest factor of inverter is a critical point.
For battery sizing, actual load current profile should be considered as per IEEE-1115.
