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 MidNite Classic offers arc fault detection that will be required by the NEC. These charge controllers also include ground fault protection so that a separate GFP breaker assembly is not necessary and leaves those breaker spaces free for other uses.
There are currently 3 Classic models that can accommodate large solar arrays with up to 150, 200, or 250 VDC of operating voltage.
MidNite model: Classic 200
- 200VDC input MPPT charge controller
- 12VDC-72VDC battery charging output
- Controller 63-79Amp output
- Built-in communication ports
- 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, wind or hydro with user adjustable power curves, and a learning mode for self optimization. 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.
The Classic charge controllers have built-in Ethernet, USB and RS-232 ports for two-way communications. An internal IP address allows the Classic to be a mini web server when hooked up to broadband. It has 32 MB of memory for data storage. A wizard driven setup covers battery bank size, string voltage, wind turbine selection, power and wire loss chart, PV breaker sizing and more. Firmware is user upgradable by downloading files.
