General mounting guidelines (for S1-200 and S1-700)
To ensure a long and reliable system lifetime, follow these recommendations when mounting the S1 controller.
- Do not expose the controller to direct sun.
- A shaded location is best.
- If possible, protect it from rain.
- Ensure airflow for ventilation.
- Do not install the S1 controller in a sealed or airtight box.
Mounting the S1-200 controller
The S1-200 controller can be mounted:
Underneath a PV module
See the following video tutorial: "Mounting the controller beneath the PV module"
On a wall
See instructions and examples here:
Mounting the S1-700 controller and PV Disconnect
The S1-700 must always be installed together with the PV Disconnect. Due to the short length of the MC4 cables from the PV Disconnect to connect to the S1-700 controller (50 cm / 1.6 ft), we recommend that both units should be mounted close to each other. You can mount them:
On a wall

On a pole beneath the PV modules
Both devices can also be installed underneath the PV modules using an optional bracket accessory, available for 2.5” (19-004220) and 4” (19-004210) pole diameters. Please contact your LORENTZ distributor for more information.
