Step 3: Determine charge controller type

There are two different charge controller types - pulse width modulation (PWM) and maximum power point tracking (MPPT) - each of which has advantages and disadvantages that are are detailed in Charge controller types. Two separate designs may be performed with each type of charge controller to determine the best system design. The current and voltage rating of the charge controller will be determined during the Simplified PWM charge controller sizing and selection or Simplified PWM charge controller sizing and selection design process.
