Product Overview
**A new 6-stage smart PWM controller kit is now available. Please consider the PVCM25D-MPT-Li with display kit **
**The SunExplorer (Part#PVCM25D & SEDM4-25) units are only compatible with the SunExplorer 25 Amp charge controller kit. The parts ARE NOT interchangeable with other parts from other kits.**
The SunExplorer (25Amp Display Kit) charge controller handles up to 25 Amps at either 12 or 24 volts DC. It is ideally suited for RV’s, Motor homes, off-grid applications, such as small cabins, remote homes, or other off-grid applications.
The PVCM25D micro-processor based photo voltaic (PV) charge controller connects PV panel to 12V or 24VDC storage batteries. PVCM25D determines which mode to operate in, 12V or 24V, by measuring both battery and PV charge voltages. PVCM25D performs five basic functions:
- Senses when the battery is fully charged and disconnects the PV charge current to avoid over-charging the battery.
- Resumes charging the battery when the battery voltage has dropped sufficiently to accept additional charge current.
- Checks the availability of PV charge current, by cycling the relay every 4 minutes. If there is insufficient charge current available, it will disconnect the battery to prevent discharge through the PV panels at night.
- Compensates for battery temperature and adjusts the charge threshold voltages when mounted in battery case.
- If the PV charge current is insufficient, it exits the charge routine to prevent battery discharge through the PV panels.
The SEDM6-25’s normal display indication is battery percent remaining and its associated LED. The select button allows the user to turn on the display’s backlight, advance to the next display setting, reset the solar Amp hour accumulator, lock display or current setting, or activate scroll mode. The SEDM4-25 will automatically switch back to the battery percent remaining display setting after 4 minutes unless the display setting 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 PVCM25D micro-processor based solar charge controller. The SEDM4-25 is a high quality brushed aluminum face plate.
