Finally, a Solar Surface Pump Built for Irrigation!

Put the Sun to Work watering your plants. The S100 and the S200 are small solar-first pumps that run efficiently off small arrays, or small, low voltage battery banks. They are designed to pump standard irrigation flow rates of 4 to 5 GPM at 15 to 20psi of pressure, perfect for drip irrigation with no danger of over pressurizing your system. Run all day on solar alone, or add the '+Nighttime' package which includes a controller for battery hookup and a pressure switch or tank float for shut-off. This allows for use with standard zone-based irrigation timer valves. When a valve in the system closes the pressure will increase and trigger the pressure switch (not included), shutting the pump down. 

The controller stabilizes the voltage to charge batteries and power your booster pump. During the day, the sun charges the batteries so they can provide power at night or early/late in the day for irrigation. 

This is not the pump for large sprinklers and is a better fit for zoned emitters, drip tape, or soaker hose. More accurate water estimates to come but rough estimates are below.

Regular Kits include:

  • Mono-crystalline solar panels (2 to 4 depending on kit)
  • 12V or 24V DC brushless solar surface pump with built-in controller, 1" FNPT outlet and inlet
  • Wire to MC4s to connect solar panels (15 ft)
  • Parallel splice connectors (depending on kit)
  • 2x 1" PVC barbed connectors to attach pump to 1″ black poly pipe tubing with hose clamps
  • Installation Manual with step-by-step instructions

+Nighttime add-on includes:

  • Solar charge controller 
  • Wire from solar charge controller to alligator battery clamps
  • Wire/connectors to connect pump to controller  
  • Choose Pressure Switch OR Float switch with MC4 prewired to cutoff at pressure or at tank full/empty


Batteries:

If adding +Nighttime add-on, you will need to add batteries to this system. Batteries must be deep-cycle batteries, not standard car batteries. Deep-cycle batteries are designed to take much lower continual discharges than regular car batteries and are usually sold as “marine” or “RV batteries.” Deep-cycle batteries normally have an “amp hour” rating shown as Ah (e.g., 100 Ah). Generally deep-cycle batteries are sold in 6 and 12 volt varieties. RPS customers tend to opt for 12V AGM batteries as they are great ‘bang for the buck’ and simple to wire. 100 Ah is a popular size; Group 27 is also a good alternative, which is around 90 Ah.

Wiring Batteries: You'll need to wire two 12V batteries in series (or four 6V batteries) to achieve the desired 24V of the S200 or S200+

**Needs positive pressure prime. Ideally pump from lower outlet of tank so prime is kept.
***Numbers Based on 6 hours per day of solar irradiance

If you are buying an RPS 200 or RPS 400 Well Pump Kit, or already have one installed, you can add a booster pump to your system by selecting 'Pump Only'.
