To protect your LORENTZ S1 controller from damage, it’s essential to ensure that the total open-circuit voltage (Voc) of your PV array does not exceed the maximum allowed. This value depends on the specific controller model.
Use the table below to confirm the maximum permissible Voc for your system. Always check this before installation, and whenever changing or adding PV modules.
Important: Exceeding the maximum input voltage can result in permanent damage to the controller. Always calculate the total Voc of your PV array based on the module specifications and the number of panels connected in serie.
Maximum Voltage Limits (Voc)
| Model | S1-200 | S1-700 |
| Maximum Open-Circuit Voltage (Voc) | 55 V DC | 220 V DC |
Troubleshooting
WARNING - Disconnect power from the controller before performing any installation, inspection, maintenance or cleaning activities on the motor or pump.
