Solar Charge Controller FAQ
-
Is it OK to oversize solar charge controller?
A voltage window is generally given, for example between 18V and 150V for a 12V battery bank. If you size the array lower than 18V, there won’t be enough voltage from the solar panels to properly charge the battery. But if you go over the high voltage, you can permanently damage the charge controller.
-
What are the two types of solar controllers?The two major types of solar charge controllers are:
- Pulse Width Modulation (PWM) controllers.
- Maximum Power Point Tracking (MPPT) controllers.
-
Do I need a charge controller between solar panel and battery?
Solar charge controllers are an essential element to any solar electric panel system. At a most basic level, charge controllers prevent batteries from being overcharged and prevent the batteries from discharging through the solar panel array at night.
