48volt 50a solar charge controller

  Our MPPT solar charge controller is a powerful tool for maximizing the efficiency of your solar power system. Using advanced technology, our MPPT controller is able to monitor the voltage and current of your batteries in real time, ensuring safe and efficient charging and discharging.#mppt battery ‎150a ‏charge

Now we will design a PV system with a MPPT charge controller. We will use the same Solaria module. The PV output voltage will have to be decreased to match the charging voltage of the battery, about 12V. This time however, the output current will increase to ensure that the overall power transfer is maximized.

To find out what the ideal current rating of the output will be we will need do the following.

Maximum Output Power / Battery Charging Voltage x Temperature Correction Factor 

330W / 12V * 1.25 = 34.4 A 

Note: The temperature correction factor comes from Table 690.7 in the NEC code. It is a correction factor for the local ambient temperature when sizing current carrying conductors.

Now we just have to make sure that we choose a charge controller capable of outputting 35A or more to a 12V battery. One charge controller that will work for this combination is the Outback Flexmax 60A Charge Controller from outback. This charge controller supports an input voltage of 150V and an output current of 60A.
