By constantly monitoring the voltage and current output of your solar (PV) panels, MPPT technology ensures that every drop of available power is rinsed out of your panels, and harvested for storage. The advantage of this is most noticeable when the sky is partially clouded, and light intensity is constantly changing.

FAQ: Comparing PWM and MPPT Charge Controllers
● PWM charge controller are built on a time tested technology . They have been used for years in PV systems and are well established.
● These charge controllers are inexpensive , usually selling for less than $250.
● PWM charge controllers are avaialble in sizes up to 60 amps
● PWM charge controllers are durable , most with passive heat sink style cooling.
● These charge controllers are available in many sizes for a variety of applications
● The PV input nominal voltage must match battery bank nominal voltage if you're going to use PWM.
● There is no single controller sized over 60 amps DC as of yet.
● Many smaller PWM charge controller units are not UL listed
● Many smaller PWM charge controller units come without fittings for conduit.
● PWM charge controllers have limited capacity for system growth.
● MPPT charge controllers offer a potential increase in charging efficiency up to 30 %.
● These charge controllers also offer the potential ability to have array with higher input voltage than battery bank
● You can get sizes up to 80 amps .
● MPPT charge controller warranties are typically longer than PWM units
● MPPT offer great flexibility for system growth
● MPPT charge controllers are expensive, sometimes costing twice as much as a PWM controller and are certainly more expensive than PWM controllers.
● MPPT units are generally larger in physical size.
● Sizing an appropriate PV array can be challenging without MPPT charge controller manufacturer guides.
● Using an MPPT controller forces the PV array to be comprised of like photovoltaic modules in like strings.
