More Flexibility and Features

Midnite Classic MPPT Solar ControllerThe Classic 150 charge controller from MidNite Solar offers significantly more flexibility, features and range than other MPPT charge controllers. Designed to regulate DC input from a wide variety of sources including solar PV, micro hydro and wind turbines, the Classic 150 is the only MPPT controller that has Arc Fault Detection, making it the safest controller available. The Classic 150 works with 12, 24, 36, 48, 60 and 72 volt battery banks, and can be installed stand-alone or as a multi-unit networked installation.

Past MPPT controllers have been limited to a maximum of 150 VDC. Midnite’s Classic offers 150, 200 or 250 VDC, accommodating larger string sizes and higher voltage panels. Built-in string sizing and battery bank capacity sizing are available to streamline your design process. A help mode and set up wizard help you through the learning curve.

A built-in safety measure, the arc fault detector, guards your system from threat of fire. Two auxiliary outputs allow you to divert excess power to other applications such as battery box vents or generator starting.

Midnite Solar’s Classic Charge controller works with wind, solar and hydropower systems. Wind or hydropower systems actually yield up to 50 to 250 percent more power with the “Classic”.

Another significant advance with the Classic is the ability to access your power system remotely via the internet. If you’re out of town, you can call in to the system to troubleshoot problems, and get it back in working order. If you have plenty of excess power, you can even turn on the snow-melting feature while you’re away. Remote control of Midnite power systems will be invaluable for installers, dealers and homeowners alike.

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.
