A charge controller is recommended, although not mandatory. It is recommended to get the Battery Charger Controller ZS-8AW-PP and the Solar Panel Adapter ZS-BDC-ADPT with the ZS-20-PP for your application. The adapter is a special order product and may take a bit longer to get to you and would need to be called in to place the order. The Battery charger controller is something that we do have in stock but not available to purchase online. If you would like to place an order for all three of these items, it would be best to call in at 866.332.7881 and place the order over the phone with one of our sales representatives.
