Introduction

Optimization of the PV225S MPPT will result in an increase in energy production. The user is encouraged to study the PV array’s I-V curves and to adjust the MPPT user settable parameters accordingly.

Dynamic DC Minimum Operating Voltage

The PV225S employs a unique approach to the minimum DC input voltage for operation. The CCU2 constantly monitors and calculates an average of the AC utility input voltage, thereby adjusting the required minimum DC input voltage threshold to optimize the sinusoidal AC output current waveform. Given a nominal input voltage of 208 Vac, the minimum DC input voltage threshold is 300 Vdc. On a transient basis, the PV225S does have the ability to adjust the minimum DC input voltage threshold to less than 300 Vdc.

Utility Voltage/Frequency Fault Automatic Reset

In the event of a utility voltage or frequency excursion outside of preset limits, the PV225S will stop operation and display a fault at the operator interface. Once the utility voltage has stabilized within acceptable limits for a period of at least

5 minutes, the PV225S will automatically clear the fault and resume normal operation. Voltage and frequency fault setpoints are detailed later in this section.
