150 amp SMA charge controller 4 wind turbine generator solar panel & dual meters

•Microprocessorcontrolled -- This is very important for both stability and functionality.

•Solid-State. No relays or solenoids to wear out.

•PWM (pulse width modulation) charging.(Charges using pulses of varying lengths)

•Three stage charging for better battery life.

•Both manual and automatic (30 day) equalize function.

•User changeable settings -- Several controllers on the market set the voltage levels, and that's that!

•High amp rating – 150 amps solar mode, 100 amps diversion mode.

•Over-current, over-voltage and overheat protection.

•Multiple system voltage settings – Easy to set jumper allows use on 12, 24 or 48 volt systems.

•High Contrast LED battery voltage and amperage meters.

•On/Off switch for the meters to allow extremely low idle current.

•Battery and charge status LEDs- Several controllers do not tell you what's going on - This one does!

•Push to test. - Ever wonder if your controller & load are working OK?

•Reverse polarity protected – This unit will not be damaged if you inadvertently reverse the inputs.

•Steel enclosure - with multiple conduit openings and cooling vents

•Large terminals - that can actually terminate large wire, with lugs that accept up to #2 wire.

•Extended diversion mode (EDM.)

•Works as either a solar charge controller (series), or a diversion controller for wind/hydro systems. The controller will automatically sense the appropriate mode.

•Passive cooling systems uses aluminum cooling pipes that run the length of the unit for continuous cooling of the entire unit allowing for proper operation at high power levels.

•Two internal 150-amp breakers with manual reset/disconnect.

•No blocking diodes are required for solar. The back-to-back mosfets prevent reverse leakage.

•A PWM controller that adapts its pulse logic to perfectly accommodate wind systems.Note: Continuous power handling will be reduced in hot climates or installations.
The microprocessoris the heart of the controller. The batterylevel is constantly checked by the microprocessor and compared to the active mode’s (Float, Bulk or Equalize) set point to determine how much (if any) current should flow into or out of the batteries. As the battery’s level of charge increases, so does the voltage of the battery (the battery’s level of charge can be determined by the voltage of the battery.) As the charge level increases the controller may use very short pulses of energy to “top off” or maintain the charge at the optimum level. These pulses of energy will be of varying lengths as required. This charging algorithm is referred to as pulse width modulation (or PWM), and when properly controlled, offers a very suitable method of charging deep cycle batteries to ensure good battery health and longevity.
Settingsare of course user changeable! By simply turning the set point potentiometers with a small screwdriver, you can quickly adjust the trip point for the float or bulk mode. (Equalize mode is about 7% higher then the bulk mode).
Six very powerful 230A mosfets are wired into three pairs (of two) to insure plenty of reserve capacity above the rated 150 amps this controller has been designed to handle. The mosfets are arranged in such a manner that they can handle currents in either direction; that is, they can perform in the capacity of a solar charge controller or a diversion mode controller. The controller automatically determines the proper mode of operation. If the controller senses that there is voltage on the “Solar/Diversion” terminal then it assumes that the controller has been wired as for the solar mode. If there is no voltage present on this terminal, then the diversion mode will instead be chosen. This terminal is checked often by the microprocessor to insure the controller selects the proper mode. If no connection has been made to the “Solar/Diversion” terminals, then the mode may be either.
The enclosure is heavy gauge, solid steel, ready to mount. -- No plastic, no junk, simple and rugged.
This Hoffman pull box is perfect for terminating larger wire. It has multiple knockouts on each side of the box. The box measures 8.25" x 12". The electronics are fully isolated from the box.
