About product

MIDNITE Charge Controller MPPT 79А CLASSIC 200-SL

MidNite Solar Classic 200-SL MPPT Battery Charge Controller.

MidNite Solar Classic 200-SL charge controller is a simplified SOLAR ONLY version of the Classic 200 with streamlined menus. Accommodates solar arrays with operating voltages up to 200 VDC. Has a graphics panel and Ground Fault Protection (GFP) which makes a separate GFP breaker assembly unnecessary but no arc-fault detection or Ethernet capabilities. BTS is sold separately.


  • HyperVOC protects the controller when open-circuit voltage exceeds the operating voltage by a margin equal to or less than the battery bank voltage.
  • Can be stacked with other Classics to act as one large controller without a separate hub.
  • Built-in USB and RS-232 ports which allow two-way communication.
  • 32 MB of internal memory for data storage. The user can upgrade the firmware using downloaded files.
  • Sealing kit for protection from dusty or salt-air environments. Sealing can reduce output by up to 20%.
  • MidNite 300 VDC breakers are recommended for power-source voltages over 150 VDC. Make sure that the breaker fits into your DC power center, or use a separate MidNite Big Baby Box.
  • Two auxiliary relay outputs. AUX1 can be programmed to either be a 12 VDC output (200 mA max) or as a dry-contact relay (1 A max). AUX2 can either be a 12 VDC output, a logic input or a PWM signal output for diversion load control or for connection to a MidNite Clipper.

The Classic charge controller conforms to UL 1741 and CAN/CSA C22.2 No. 107.1:2001/09/01 Ed: 3 (R2006) and is covered by a 5-year warranty. Dimensions are 14.9" x 6" x 4", and weight is 11.5 lbs for all units. Made in the U.S.A.

I purchased panels, batteries, an inverter and this controller here two months ago. The staff was very helpful and professional, their calculator is very convenient for sizing the system. The shipping took a little longer than expected due to some holidays, but it’s all good. nothing was damaged, nothing was missing. Good job!

I didn’t know that charge controllers were a thing, but read a couple articles on your website and they were quite helpful. My last two batteries did in fact die too quickly and for a good reason. Hope that now with a regulator the new one will last longer.

The regulator is fine. It’s well made, at least it doesn’t look like it’s going to break in the next second. the monitor is good, you can adjust the charging process and whatnot. It’s pretty efficient from what i’ve seen. solid product

hi, is it PWM or MPPT?
07/12/2021, 07:48
Good day. It is an MPPT controller.
How do I connect it to the solar system?
06/23/2021, 16:27
First the charge controller is connected to batteries. Then you turn the controller on to make sure it works. Then the regulator is connected to a solar array.
what would a controller need a memory for
06/07/2021, 10:46
The controller needs internal memory for updates. You can download the files and upgrade the firmware this way.
