 Product Description

MidNite Solar 12V 200VDC MPPT Charge Controller - CLASSIC 200-SL

Midnite Solar, Classic-SL-200, MPPT Charge Controller, PV only, 200VDC, 79A Max, 12-72V Battery, with LCD, GFP, BTS, No Arc-Fault or Ethernet, CLASSIC 200-SL

MidNite Solar's Classic charge controllers offer many useful features including arc-fault detection (not currently listed to UL 1699B) and Ground Fault Protection (GFP) which eliminates the need for a separate GFP breaker assembly.

Three sizes are available to accommodate solar arrays with operating voltages up to 150, 200, or 250 VDC. A feature called HyperVOC protects the controller from damage when open-circuit voltage exceeds the operating voltage by a margin equal to or less than the battery bank voltage. The table below represents maximum power only. Be sure to consult the power curves in the user's manual when sizing your PV array as allowable current varies with array voltage.

MidNite Solar’s Classic controllers have MPPT modes for solar, wind, or hydro with user-adjustable power curves, and a learning mode for self-optimization. Classics can be stacked to act as one large controller without a separate hub. The Classic has built-in Ethernet and USB and RS-232 ports for two-way communication. Each unit has 32 MB of internal memory for data storage. Firmware is user upgradeable using downloaded files. Each unit includes a sealing kit for dusty or salt-air environments, but sealing can reduce output by up to 20%. Use MidNite 300 VDC breakers (see Electrical Distribution Parts) for power-source voltages over 150 VDC. Make sure that the breaker will fit into your DC power center, or use a separate MidNite Big Baby Box (see Electrical Distribution Parts) to accommodate the breaker. On the battery side of the controller, breakers need only be rated for the highest battery-charging voltage.

The Classic controllers have 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 (for instance it could allow control of the Classis by a signal from a battery BMS) or a PWM signal output for diversion load control or for connection to a MidNite Clipper.

The Classic 150, 200 and 250 are listed to UL 1741 and CAN/CSA C22.2 No. 107.1:2001/09/01 Ed: 3 (R2006) and are covered by a 5-year warranty. Dimensions are 15"H x 6"W x 4"D, and weight is 11.5 lbs for all units. Made in U.S.A.

The Classic SL is a lower cost solar-only version similar to the standard Classic. They do not have wind or hydro modes. SL versions have a streamlined menu, and built in Ground Fault Protection, but no Arc Fault Detection, or auxiliary outputs. BTS sold separately for these models.

The MidNite Graphics Display Panel (MNGP) is a remote LCD display that mimics the interface on the Classic charge controllers. It can also be used with the Lite versions of the Classic series.

The MidNite MNSICOMM is an adapter that allows the SMA Sunny Island to control the set points on a Classic control and will read the Classic data on SMA’s monitoring platform.
