The S1-700 is a plug-and-play solar pump system designed for quick and easy installation. Follow these steps to install your pump in any clean water source:
Install the S-Connect app
IMPORTANT: Using the S-Connect app is optional, as the pump is ready to operate straight out of the box without the app.
Use this app to locally monitor and manage your pump system via Bluetooth™.Connect an adapter and a pipe to the pump discharge
- Install an adapter that matches the thread type and discharge size of your pump end. The adapter material depends on the type of pipe you are using (plastic or metal) and must be sourced locally. Refer to the table below:
| Pump model | Discharge size | |
| CST-2-10 | Rp 1-1/4” | NPT 1-1/4” |
| CST-4-6 | Rp 1-1/2” | NPT 1-1/2” |
- Then connect a pipe that is appropriately sized for the discharge.
Attach a safety rope to the pump
This is important for safely lowering and retrieving the pump.
Mount the PV Disconnect and the S1-700 controller
Ensure the S1-700 controller and PV Disconnect are installed close to each other — the MC4 cable between them is only 50 cm [1.6 ft] long.
For detailed guidelines, see the following article:
Connect the PV modules in series
Ensure correct wiring for optimal performance.
IMPORTANT: The total open-circuit voltage (Voc) of your PV generator must not exceed 220 V or the controller will be damaged.
For more information, refer to the following article:
Connect the motor cable to the S1-700 controller
Watch the following video to see how to connect the motor cable to the controller:
Connect accessories (if applicable)
Install any accessories such as Dry Run Protection, Tank Full Switch, or Remote Tank Switch, and connect them to the appropriate sockets on the S1-700 controller. The activation of the accessories will be done later in step 13.
For more information refer to the following articles:
In the example below, only the Dry Run Protection is being connected, if you wish to connect the other two sensors, do so in the corresponding socket.
Connect the PV Cables (MC4) to the controller and PV Disconnect
Ensure both the PV Disconnect and the S1-700 controller are turned "OFF" during connection.
Ground the S1-700 controller
For grounding instructions, refer to:
Position the PV modules to face the sun
Submerge the pump in water
Turn on the PV Disconnect first and then the S1-700 controller
Configure your S1-700 pump system
If you are NOT using the S-Connect app:
After turning on the PV Disconnect and the controller, you must manually activate any accessories connected in Step 7 (except for the Remote Tank Switch, which can only be activated via the app).
See the following guide with videos explaining how to manually activate accessories without using the app:
If you are using the S-Connect app:
- Connect to the S1-700 controller via Bluetooth™
- Select the correct pump end, andthenenter the correct total dynamic head (TDH) of your installation
- Activate the accessories connected to the controller
- Configure your system using the functions described here:
