Configurable PWM solar charge controllers

Because of the lower price point of PWM controllers they are often less configurable than MPPT controllers. Still, PWM controllers with configurable setpoints do exist.

Morningstar TriStar PWM


The TriStar TS-45, and TS-60 PWM professional grade controllers are configurable with a cable.

Note that the MPPT variants are also called TriStar but the model numbers are TS-MPPT-45, TS-MPPT-60, and there is also a 30A TS-MPPT-30 unit for which there is no PWM counterpart.

Morningstar SunSaver Duo Duo (two battery) line is configurable with MSView.

Victron PWM-pro The Victron PWM-pro is fully programmable by USB adapter and free software.
