Review on WindyNation P30 30A Solar Panel Regulator Charge Controller: Efficiently Powering 12V and 24V Systems up to 780W by Elijah Pope

Incredible amount of features. Twilight function via solar panel output, day only, night only, time output or 24 hour download. Charging, load and continuity status LEDs help you troubleshoot your system with an incredibly sophisticated device. In old age you need all the benefits you can get.
