Commercial 20kW 480V Three Phase Gridtie System

Wholesale Solar’s 20kW Gridtie Commercial System includes high quality Astronergy modules with the SolarEdge Inverter System — a revolutionary way of maximizing the sun’s power using SolarEdge Power Optimizers. The SolarEdge Power Optimizers maximize energy throughput from the modules through constant MPPT tracking. Because SolarEdge Power Optimizers automatically maintain a fixed string voltage, the SolarEdge inverter works at optimal efficiency.  Benefits include:

  • Up to 25% increase in power output.
  • Faster installations with less wiring.
  • Maximum roof utilization.
  • Safest solar system! With built in arc fault detection and SafeDC feature.
  • Built-in monitoring for unprecedented remote maintenance capabilities.
  • 25-year warranty on power optimizers and 12-year warranty on inverters.

Why is a SolarEdge System Better Than a Traditional Gridtie System? In a traditional gridtie system, if only one solar panel in your system is shaded or is down, each and every other solar panel in the array replicates the same power output, reducing the entire system’s power output.  In a SolarEdge system, Power Optimizers are paired up to each solar panel allowing panels to operate independently at optimal performance.

Fewer Constraints and More Flexibility in the Design Process:

  • Temperature is not a factor because fixed string voltage ensures the inverter always operates at its peak efficiency voltage and prevents under-voltage power losses even on hot days.
  • Panels don’t all have to be facing the same way.
  • Different string lengths can now be accommodated.
  • Solar power ratings and technologies can vary.

Monitoring Options for Your System. The SolarEdge Module Monitoring portal is a web-based application that provides performance monitoring of your solar panels, fault detection and automatic alerts for accurate troubleshooting localized on a virtual site map. Monitoring is simple with the use of ethernet cable, ethernet bridge, or GSM cellular connection (sold separately.) If you have any questions regarding this system, or would like to request a shipping quote, call us at 1-800-472-1142 or email [email protected].
