Another Classic. Like the gold standard Classic 150, the MidNite Classic 250 is a sophisticated solar, wind, or hydro MPPT charge controller designed to support nominal battery system voltages up to 72V. But unlike the Classic 150, this controller is designed for up to 250 DC volts input and 63 amps output.
Features. The Classic 250 offers an impressive set of features including free wireless data monitoring, built-in DC ground fault protection and arc fault detector, and distinct solar, wind and hydro operating modes. Also ships with MidNIte's battery temperature sensor (the WhizBang Jr. current sensor module is sold separately). For more detail on MidNite Classic 250 features, please see the additional documents below.
HyperVOC One particularly unique feature of MidNite Classics is HyperVOC. HyperVOC allows Classic charge controllers to extend their maximum open circuit voltage (Voc) limit when needed. For example, the Classic 250 has an input voltage rating of 250 Voc. If the Classic 250 is connected to a 48 volt battery bank, the HyperVOC voltage limit will be: 250V + 48V a total of 298 Volts that the Classic can manage. Why is this helpful? Because a system's voltage could creep past the normal Voc limit on a really cold morning. See this Midnite document explaining HyperVOC here.
Warranty. The Classic 250 comes with a standard 5 year warranty against defects, during which time MidNite Solar will repair or replace the Classic at no charge to the consumer during this 5 year period. In addition, MidNite Solar continues to offer their pioneering extended warranty. Customers can ship their Classic 250 to MidNite during the final 6 month period of the standard 5 year warranty together with a check for $147 and MidNite will replace any wearable items and perform a general tune-up. This will also extend the Classic 250's warranty by 2 additional years. Click here to see the latest info on the Classic 250 warranty.
