Solar Charge Controllers

Features and add-ons. Once you have decided on a type of controller, you'll want to identify what features you need. There are many basic-no-frills charge controllers that work well. In addition, there are some great features that will make your renewable energy experience even better. An important addition to your system: battery (Temperature Sensors). Battery capacity depends on temperature, therefore proper battery charging can be significantly enhanced with a temperature sensor. Additionally, some controllers offer control set points, low voltage disconnect, overload protection and displays and metering. If you plan to run a DC load, you can connect it directly to the charge controller. If the charge controller is equipped with a low voltage disconnect (LVD), then the charge controller can detect when the battery is low and shut off the DC load until the battery is charged. Is all of this still confusing? Give us a call and let us know the short circuit current of your array (or at least the brand and size of your modules) and the system voltage (12, 24, 48 VDC) and we'll be glad to help with a recommendation.
