SunExplorer II 40D-MPT: 40Amp Multi Point Tracking Kit with Display


Product Description

** The PVCM40D-MPT charge controller is only compatible with the SEDM6-40 display unit (A0444) originally sold in the PVCM40D/SEDM6-40 kit. The PVCM40D-MPT controller is a drop in replacement for the two stage PVCM40D controller.**

If you’re ready to update your trailer charge controller to smart 6 stage charging, here is a drop in replacement that keeps the factory look. You can use the old display.

The 40 Amp solar charge module with Multi Point Tracking (MPT) controller (PVCM40D-MPT) is a rugged inline solar charge controller. It uses Pulse Width Modulation (PWM) to control the solar charge current. The controller delivers the maximum charging rates throughout each of the charging stages and connects between your 12VDC storage batteries. It is Ideal for RV’s, motor homes, trailers and off-grid applications such as small cabin sites.

The PVCM40D-MPT micro-processor based solar charge controller connects between the solar panels and the storage battery(s). It performs 7 basic functions:

  • It monitors the solar panel voltage to know when it has enough to start charging the battery(s) and when to stop charging due to end of day.
  • It monitors the battery voltage to know if to enter a soft charge (battery voltage below 10.5vdc or enter the bulk charge routine, when to enter the absorption and float routines
  • It adjusts the PWM charge algorithms based on varying load and solar conditions to maintain the maximum charging rates.
  • It checks the available solar charge voltage every second to make sure there is sufficient voltage available. If not, it suspends the charging routine until the solar voltage increase or it drop below 5VDC which it then enters night or end of day routine.
  • It compensates for battery temperature and adjusts the charge thresholds voltages when mounted in the battery area.
  • It accepts the battery top-off command signal from the SEDM6-40 display to enter a charge routine to top off the battery(s).
  • On power up it checks its battery type dip switch and sets to correct routine for that battery type.

The SEDM6-40 is the display unit for the PVCM40D-MPT controller, Its normal display is battery percent remaining and it associated LED. The select button allows the user to turn on its back light, advance to the next display setting, reset the solar Amp hour accumulator, force the PVCM40D-MPT into a charge routine to top-off the battery(s) when controller is in float mode, lock the display on the current setting, or activate scroll mode. The SEDM6-40 will automatically switch back to the battery percent remaining display setting after 4 minutes unless the display is lock is activated. The backlight will come on for 15 seconds any time the select button is pushed and will stay on continuously in scroll mode. The SEDM6-40 has a high quality brushed aluminum face plate.
