About the image in our logo: This is a microwave repeater accessible only by helicopter after a 3 hour flight (one way). There is no place to land so all equipment and personnel must be lowered by rope. This image was the inspiration for our endeavor to create the most reliable PV controller available.
* Battery must be in good condition and be capable of accepting charge.
