Features and benefits



 

SunWize® PowerPort

The SunWize PowerPort easily fits into any existing space because of its design flexibility. The PV array is located on the roof deck of a canopy structure that provides shade for various purposes such as vehicle parking, park visitors, and sports spectators. The low tilt angle of the deck and array reduces wind loading and maximizes power output to coincide with peak electrical load periods.The system’s simplicity minimizes engineering costs and on site construction time.
The system transforms direct current power produced by the solar modules into 480 VAC, 60 Hz, 3-phase utility-compatible power that is fed into the utility. In this grid-interactive configuration, the PV system operates in parallel with the utility power plants to provide power to the grid during daylight hours.

Automatic Operation
The inverter operation is completely automatic. It ‘wakes up’ and begins to deliver power as the sun rises and ‘sleeps’ as the sun sets. The inverter monitors and matches utility voltage, frequency and phase angles. In the event of a utility loss of phase or complete power outage, the inverter shuts down to ensure the safety of utility line workers. Upon restoration of utility grid power, the inverter resumes operation. System capabilities include fault detection and diagnostics with no operator intervention.
