Product Overview
The SunExplorer III is a six stage, micro-processor based, Pulse Width Modulated (PWM), and Multi-Point Tracking (MPT), solar charge controller with a high quality brushed aluminum display in one unit.
The controller connects between the solar panels and 12VDC storage batteries to regulate charge. The SunExplorer III controller automatically charges your battery to 100% and keeps the battery in float stage. If your battery gets to low, it goes into Automatic Boost Mode keeping your batteries full and extending the life of your batteries by regulating the PWM rates, and disconnects the batteries at night to prevent discharge thru the solar panels. The SunExplorer III provides an automatic equalization stage for lead-acid (wet) batteries.
The SunExplorer III can handle up to 620 Watts but check the current rating on the solar panel because each manufacturer can be slightly different.
