1. In appearance
1.) Different size: MPPT solar charge controller case is about 5cm thicker than PWM case;

2.) MPPT solar charge controller with handle, PWM without.
3.) The Mppt solar charge controller contains large capacitors, inductors and IGBT modules, which require a large area of heat dissipation. Therefore, the heat dissipation of the MPPT controller is designed to dissipate heat through the bottom. In the PWM solar charge controller, there are only IGBT modules, without large capacitors and inductors. So the side heat dissipation method is adopted.
Mppt: without heat dissipation on both sides |
PWM:without Bottom heat dissipation |
Mppt:without heat dissipation on both sides |
PWN controller heat dissipation on both sides |
2.Internal structure
The MPPT solar charge controller contains large capacitors and inductors, but PWM solar charge controller does not.
(Note: There must be large capacitors and inductors inside the MPPT solar charge controller. Otherwise, it is a PWM solar charge controller)
