We stock a wide range of both MPPT & PWM solar charge controllers. See the BlueSolar and SmartSolar Charge Controller MPPT - Overview. In the MPPT model names, e.g.. MPPT 75/50, the first number is the max. PV open circuit voltage. The second number, 50, is the max. charge current. Use the MPPT Excel sheet or Online MPPT Calculator for PV sizing calculations.
For more info about PWM or MPPT charge controllers, read Victron's whitepaper: which solar charge controller: PWM or MPPT?
