Sirio ES 110
Sirio ES 110 – Three-phase string inverter, 8 Mppt

Three-phase string solution by Riello Solartech, for the optimization of construction and operating costs of commercial and industrial plants.
The model of the string inverter family has been designed with the aim of maximizing the return on investment in decentralized applications both on the roof and on the ground.

Compact and lightweight design
The product design includes a small footprint and an aluminum case that makes them particularly light for their category, thus saving on installation costs and resources.

Ease of installation
Sirio ES 110 is ideal for both roof and ground installations.
Integrated surge arresters and circuit breakers for immediate installation.

Advanced connectivity
The Bluetooth connection from any mobile device makes configuring the inverter quick and easy.
The dedicated APP allows for quick configuration of the inverter.

Fast system integration
Its communication protocols, Bluetooth and RS485, allow fast and intuitive system integration.
An Ethernet port (optional) and optional Wi-Fi connection guarantee fast communication for any system requirement.

Compatible with the Riello Solartech supervision portal
Plant monitoring is facilitated by the possibility of connecting each inverter to the RS Monitoring platform, guaranteeing investment security and long-term savings control.
