Solarpex Mppt Solar Charge Controller 40amp

Solarpex, Mppt solar charge controller 40amp, mp-40

Mppt checks output of pv module, compares it to battery voltage then fixes what is the best power that pv module can produce to charge the battery and converts it to the best voltage to get maximum current into battery. It can also supply power to a dc load, which is connected directly to the battery.Mppt is most effective under these conditions:
cold weather, cloudy or hazy days: normally, pv module works better at cold temperatures and mppt is utilized to extract maximum power available from them.
when battery is deeply discharged: mppt can extract more current and charge the battery if the state of charge in the battery is lowers.
