100a 120a mppt solar charger controller

Choosing the most suitable charge controller is simple and only requires two steps:

Step 1 – Voltage selection

   Select a charge controller that is compatible with the system voltage. The standard configurations are 12, 24, and 48 volts. If you are wiring your batteries for 24 volts you need a charge controller that is rated at 24 volts.

  Some controllers are voltage specific, meaning that the voltage cannot be changed or substituted. #solar charger controller 12v        Other more sophisticated controllers include a voltage auto-detect feature, which allows it to be used with different voltage settings.

Step 2 – Current capacity

    Select a charge controller that can handle the maximum output current of the solar panel (or solar array). The maximum possible current that a PV panel can generate is the “short circuit current,” indicated as Isc in the panel’s label or specs sheet.

    It’s recommended to include a safety factor for isolated events as well.#96v 120a mppt       For example, a solar panel with a LSC of 7.89 amp could potentially produce an extra 25% on a sunny day with very clear snow pack. (additional light reflected off the snow). #solar tracking controller      This results in a possible maximum of 9.86 amp (7.89 x 1.25 = 9.86 amp). In this case, a 10 amp charge controller would be recommended.
