Shurflo Submersible Pump Controllers 902-100, 902-200


Pay Over Time with Bread Pay™


Boost your DC solar pumps performance by up to 30%. Controller optimizes your solar water pumping system by translating the current and voltage available from your photovoltaic panels, into a combination that is better matched to that needed by the pump. With the optional float switch installed, the controller will automatically stop pumping when the reservoir is full.

So why should you get a controller with your pump? Well, bottom line is they allow you to get more power out of your solar array, and really optimize the power you get from your pump. The design allows 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 specifically 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. See more features below. So even on less than optimum solar days, you can get more consistent, reliable performance from your pump, when used with a controller.
