SolarEdge commercial three phase inverter SE50K – SE55K – SE82.8K

Three-phase inverters for commercial systems with synergy technology. Composed of several separate units that are easy to connect and easy to install thanks to their reduced weight and size.

  • Independent operation of each unit enables higher uptime and easy serviceability
  • Specifically designed to work with power optimizers
  • Fixed voltage inverter for superior efficiency (98.3%) and longer strings

New generation of three-phase inverters with synergy technology available in Italy in the following sizes: 50kW, 55kW, and 82.8kW as well as 66.6kW and 100kW for medium voltage grids.

Specifically designed to work with power optimizers.

The inverter consists of several separate units of small size, easy to transport and install, which can be connected to each other by cables. This solution allows an easy and fast installation by two people and significantly reduces labor costs. Furthermore, the independent operation of each unit allows greater operability and ease of maintenance.

Assembly flexibility

No wasted ground area: wall/rail mounted or horizontally mounted under the modules (10 ̊ inclination).

Integrated monitoring

Built-in module-level monitoring with Ethernet or cellular GSM.

Simplified commissioning

Activation, commissioning and configuration of the inverter are now carried out directly via the SetApp application for smartphone.

Fixed voltage

Fixed voltage inverter for superior efficiency (98.3%) and longer strings.

Security and protection

Integrated Connection Unit with optional integrated DC Safety Switch – eliminates the need for external DC isolators.
Built-in RS485 Surge Protection Device, to better withstand lightning events.
