Classic String Sizing Tool

The MidNite Solar Classic MPPT charge controller is the most advanced controller on the market. It comes in three standard models (150, 200 and 250 volts) which will charge up to 72 volt battery banks using solar, wind or hydro power. The 250KS model will charge up to 120 volt battery banks. The model number corresponds to the maximum operating voltage that the controller can handle on the input side. The Classic is also the safest controller available due to its built-in ground fault and arc fault protection. No other controller offers the built-in arc fault protection. This means that the MidNite Classic is the only controller that fully complies with the 2011 National Electric Code regulations without having to add additional equipment to your system. Not only is the Classic the safest, but it's also one of the easiest to set up and use. MidNite Solar has taken the guesswork out of setting up your system by implementing a set up wizard with voice prompts. The wizard can help walk you through battery hook up, PV array sizing and hook up, wind turbine program selection, wire sizing, breaker selection, PV combiner selection, sunrise and sunset program set up and voltage drop calculations. Take a look at this chart to see how the Classic compares to the competition.
