Midnite Solar Classic 150 SL Solar Charge Controller

The Midnite Solar Classic 150 SL Charge Controller offers the full solar charging feature set of the original Classics, without the hydro and wind turbine control features; resulting in a drastically lower product price, with the same Midnite quality. 

The MidNite Classic charge controllers are full-featured Maximum Power Point Tracking (MPPT) solar charge controllers which maximize photovoltaic (PV) array capacity and layout flexibility more than other controllers in their class. These controllers also feature arc fault detection, as well as ground fault protection, so that a separate GFP breaker assembly is not necessary.There are three models available that accommodate solar arrays up to 150, 200, or 250VDC of operating voltage.

MPPT modes with user adjustable power curves are built in, along with a learning mode for self-optimization. No hub is required for stacking multiple units. They have two auxiliary outputs, a dry contact relay and a 12V output. Optional snap-on covers and hole plugs for sealing openings in dusty or salt-air environments are available from Midnite, though using them in this manner reduces output by about 20%. 

With three Classic models to choose from, use Midnite's Power Charts to pick the best one for your application.  By knowing your battery bank voltage, and the array voltage, you can determine the maximum array wattage that each model can support.

As well as their excellent features, Midnite Solar is a proudly American company based in Arlington, Washington. Their history goes back through several decades of electronics and solar companies in the Pacific Northwest. Midnite Solar products are made and supported in the USA.
