How do I choose the right type of charge controller?
PWM (Pulse Width Modulation)
PWM charge controllers are useful when the solar panels have a matching voltage to the battery. Panels are wired in parallel and operate at the same voltage as the battery.
Panels up to 150 watts will work with a 12 volt system; panels above this wattage rating will operate with a 24 volt system. PWM charge controllers are automatically switchable between 12 and 24 volts.
Available in 10, 20, 30, 40 and 60 amp units.
Available with or without a display.
MPPT (Maximum Power Point Tracking)
Required when you need to step the solar panel voltage down to the battery voltage. These controllers can accept up to 150 volts of Solar input.
A higher panel voltage allows the panels to be located further away from the off-grid system and allows smaller wiring to be used.
With these controllers you can connect the panels in any series / parallel configuration, to allow complete freedom of installation.
Available in 10, 20, 30, 40, 60, and 100 amp units.
Available with or without a display.
