The MidNite Classic charge controller offers maximum flexibility and a number of features that will increase the reliability of your off-grid systems and the life cycle of your batteries. The Classic-SL is a solar only version of the standard Classic MPPT charge controller. It is a simplified version that does not include arc fault protection and it does not include Ethernet capabilities therefore the controller cannot be connected to the internet. Features like the use of My Midnite and Local App are disabled.
The controller comes with the standard ground fault interrupter to provide a safe installation. The graphics panel and the setting menu have both been simplified. The SL controllers do not include the dip switch programming that you find in the standard Classic model.
All Classic SL models are solar only charge controllers. They are not compatible with the output voltage of wind and hydro energy systems. All Classic SL charge controllers come with a 5 year warranty.
There are currently 3 Classic SL models that can accommodate large solar arrays with up to 150, 200, or 250 VDC of operating voltage.
MidNite model: Classic 150-SL
- 150VDC input MPPT charge controller
- 12VDC-72VDC battery charging output
- Controller 76-96Amp output
- Simplified graphics and menu
- Integrated ground fault protection
Open circuit voltage (Voc) is based on operating voltage plus the battery voltage. This is called the HyperVOC zone. The Classic charge controllers have MPPT modes for solar only. No hub is required for stacking Classics to act as one large controller.
They feature two auxiliary outputs, a dry contact relay and a 12V output. Each unit includes snap-on covers and hole plugs for sealing openings in dusty or salt-air environments. Keep in mind that about 20% reduction in output will result when used in sealed mode.
