Today’s award for making a thing right the first time that never needs to be changed goes to Morningstar. Morningstar’s SunSaver Controller series is approved for use in hazardous locations outlined in the classifications: Class 1 (presence of flammable gas, liquid or vapor), Division 2 (absence of ignitable concentrations under normal conditions) , Groups A & D (acetylene, propane, gasoline, naphtha, benzene, butane, ethyl alcohol, acetone, methane). Its construction is tropicalized, hardened and encapsulated for field use in extreme conditions, and includes full electronic protections. Proven in demanding oil and gas use, it’s now a leading solar controller for general industrial and even consumer use for users who want top professional quality in their own systems.
