Morningstar Charge Controllers

Sunsaver, SunSaver MPPT, ProStar, TriStar, Relay Driver, SunKeeper, Dual battery controllers

All of the ProStar controllers come standard with conformal coating and are suitable for marine and high humidity applications.

Morningstar is our most popular line of charge controllers. Morningstar's superior series switching provides many advantages. Series regulation reduces FET heating and lowers voltage stress on the power FET. A series configuration also improves protection against lightning surges and reduces switching noise.

The Morningstar SunSaver & SunKeeper series are Class 1, div 2 (A,B,C,D) hazardous location approved. Those are the ONLY solar charge controllers that is approved for hazardous locations, for use in such places as gas pumping stations, refineries, etc.

All Morningstar controllers include the following standard features
Temperature Compensation		High efficiency, low self consumption
Constant Voltage,PWM series charging		High level of lightning protection
Reverse current protection (at night)		Operating temperatures of -40C to +85C
No need to derate- 25% design margin		Epoxy encapsulated (except for ProStar)
ISO 9002 manufacturing		Five year warranty
Computerized production testing		Parallel capability for higher current ratings

Low Voltage Disconnect (LVD) - Do I need it?

Short answer is, probably not. LVD will disconnect the LOAD from the batteries if the batteries get too low (around 11 volts). About the only systems that normally use the LOAD terminals are places like remote and unattended sites, such as battery powered camera monitors or alarm systems. Those types of systems should have the LVD option, but most other systems - such as RV's, small cabin systems, any system that uses an inverter do not need it.
