The numbers refer to the unit's electrical limits, For example in the case of the Victron Energy SCC110050210 Smart Solar MPPT 100/50 Charge Controller with Bluetooth the first number (100): Is the maximum PV (Solar Panel) Open Circuit Voltage (VOC). You must ensure your panel array never exceeds this voltage, even in cold weather. The second number (50): Is the maximum charge current (in Amps) the controller will send to your battery.
