Detailed Description

SolarEdge Three-Phase SetApp Inverters
The SolarEdge three phase inverter combines sophisticated digital control technology with efficient power conversion architecture to achieve superior solar power harvesting and best-in-class reliability. The fixed-voltage technology ensures the solar inverter is always working at its optimal input voltage over a wider range of string lengths and regardless of environmental conditions.

A proprietary data monitoring receiver has been integrated into the inverter and aggregates the power optimizer performance data from each PV module. This data can be transmitted to the web and accessed via the SolarEdge monitoring platform for performance analysis, fault detection and troubleshooting of PV systems.

Easy Inverter Commissioning with Inverter SetApp
The new range of SolarEdge three phase inverters have a smart new commissioning method. Inverter commissioning is done directly through a smartphone using the intuitive SetApp mobile application. Take your inverter commissioning to the next level. NOTE: SetApp Cellular or Zigbee compatible card must be used if applicable.


  • Specifically designed to work with power optimizers
  • Quick and easy inverter commissioning directly from a smartphone using the SolarEdge SetApp
  • Internet connection through Ethernet or Wireless
  • Fixed voltage inverter for longer strings
  • UL1741 SA certified, for CPUC Rule 21 grid compliance
  • Built-in module-level monitoring
  • Integrated arc fault protection and rapid shutdown for NEC 2014 and 2017, per article 690.11 and 690.12
  • Integrated Safety Switch
  • Supplied with RS485 Surge Protection, to better withstand lightning events
  • Small, lightweight, and easy to install outdoors or indoors on provided bracket
