I am very pleased with this controller. Having 2 banks of batteries hooked up to it on our sail boat we can monitor the charging from the solar panel. This particular controller can handle another solar panel hooked to it, so, we are going to order another (from Amazon). We highly recommended this controller and the LCD screen!
