Frequently Asked Questions
What is the difference between PWM and MPTT solar charge controllers?
As you browse the commercially available solar charge controllers, you will notice that the acronyms “PWM” and “MPTT” appear. They represent pulse width modulation (PWM) and maximum power point tracking (MPPT). Here are the key things you need to know about these two types of solar charge controllers:
Pulse Width Modulation (PWM)
PWM solar charge controllers have been around for a long time and have the advantage of being on the cheaper end of the market. The technology is simple; The PWM charge controller controls the voltage and current flowing to your battery from the solar panel and allows enough current to flow to the battery to reach its voltage size. Once the optimal voltage is reached, disconnect the battery from the panel and keep the battery at its maximum voltage. While this type of solar charge controller is a reliable method of ensuring your battery doesn’t overcharge, its downside is that it only provides enough power to meet the battery’s voltage. This means that any energy generated after reaching capacity is lost.
Maximum Power Point Tracking (MPPT)
This new technology goes beyond the capabilities of the original PWM solar charge controllers and is a much more advanced and complex model. Since solar panels can often draw more voltage when sun conditions are at their peak than your RV battery is capable of handling, MPPT solar charge controllers can convert that increase into additional current. You then use it at a lower voltage without losing power, which means you can use the full power of your RV’s solar panels to charge your battery efficiently.
Besides being more efficient than PWM solar charge controllers, MPPT is also more suitable for solar panels and batteries with higher voltages. It is also the correct choice of solar charge controller when there is a difference between the voltage of the solar panel and the voltage of your battery, because you cannot use a PWM in this case.
The downside to MPPT solar charge controllers is that they are significantly more expensive than PWM models. If you rely on solar energy frequently, it is worth investing in an MPPT solar charge controller because they can optimize the energy collected by your solar panel more efficiently. While if your solar energy needs are limited to a summer vacation trip or a weekend every two months, PWM solar charge controllers will be a good choice.
