Comparing PWM and MPPT Charge Controllers When assessing which type of solar charge controller to purchase, you need to know about their functionality and features but it's also helpful to see a straightforward comparison of your options. To that end, we've put together a comprehensive look at the pros and cons of both PWM Type Solar Charge Controllers and MPPT Solar Charge Controllers for your convenience! If
you're just starting out, you may want to review How Charge Controllers
Work and How MPPT Charge Controllers Work.
* PWM charge controller are built on a time tested technology . They
have been used for years in PV systems and are well established. PWM Cons
* The PV input nominal voltage must match battery bank nominal voltage
if you're going to use PWM. MPPT Pros
* MPPT charge controllers offer a potential increase in charging efficiency
up to 30 %. MPPT Cons
* MPPT charge controllers are expensive, sometimes costing twice as
much as a PWM controller and are certainly more expensive than PWM
controllers. Return
