Why should you get a controller with your pump? Well, they allow you to get more power out of your solar array, and allow you pump water earlier or later in the day, than you normally could. It gives you an increase of about 30% more flow than you would normally have. The controllers are designed to maximize solar powered submersible pumps.
The Shurflo 902-100 Pump Controller is for 24V systems, and the Shurflo 902-200 Pump Controller is auto-sensing, can work with 12V or 24V systems. The 200 is also in a sealed waterproof box designed to operate in more extreme environments. So even on less than optimum solar days, you can get more consistent, reliable performance from your pump, when used with a controller.
Note: Do not use any SHURflo pump for petrol gasoline, petroleum products, solvents, thinners or any other flammable liquid with a flash point below 82 C (180 F).
