A MPPT controller can take a much higher voltage input and dynamically convert it to the appropriate charging voltage by increasing the amperage output. For example, if I was bringing in 39-volts of power at 1 amp, a MPPT controller can convert the voltage to 13 volts which is more appropriate to charge a 12-volt battery. But because it reduced the voltage by 1/3, it is able to triple the amp output to give me 3 amps of charge to the batteries.
There are many MPPT charge controllers out there, one of the best is the Victron SmartSolar MPPT 100/30 Solar Charge Controller 100V 30A with Bluetooth. It is compact, it can take input voltage up to 100-volts and it can produce a maximum of 30 amps of charge to the batteries. The best part is that there is a built-in bluetooth module that allows me to track and monitor the condition of my electrical system using either an Android of iOS app. This eliminates the need for a separate battery monitor.
