The Midnite Solar Classic 150 MPPT charge controller offers maximum flexibility and many features that will increase the reliability of your solar off-grid system and the life cycle of your batteries. The Midnite Classic offers NEC-compliant arc fault detection. These charge controllers also include ground fault protection so that a separate GFP breaker assembly is unnecessary 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 Solar Classic 150 MPPT Charge Controller

– 150VDC input MPPT charge controller
– 12VDC-72VDC battery charging output
– Controller 76-96Amp output
– Built-in communication ports
– Integrated ground fault protection

The Open Circuit Voltage (Voc) is based on operating voltage plus the battery voltage, 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. You will not require a hub for stacking Classics to act as one larger 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 a 20% reduction in production 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.

There Are Two Classic Charge Controllers

Midnite Solar offers two series of Classic MPPT charge controllers: the Classic and the Classic SL. Both models come in 150, 200, or 250 volts DC. The Classic is the complete model, while the Classic SL is a simplified version with fewer features. Below you can read more about the characteristics of each model.

The Classic

The Classic is a feature-rich charge controller designed by Midnite Solar. The Standard Classic features:
– 2 auxiliary outputs
– 1 auxiliary input
– Hyper VOC Extended VOC Limit
– Compatible with solar, wind, and hydro systems
– Ground fault protection
– Arc fault protection
– Graphics display
– Works with My Midnite and Local App (free firmware upgrades)
– Multiple display support
– Enabled for internet connectivity
– Five-year warranty

The Classic SL

Since most Classic controllers have been installed in solar PV systems, Midnite Solar makes the SL charge controllers. This simplified version is programmed to operate exclusively with solar PV systems.
Some of the advanced features found in the Classic have been removed from the SL units to reduce the cost of the controller further. The Classic SL does not feature:
– Compatibility with wind and hydro energy systems
– Arc fault protection
– Internet connectivity
