Product description

The flexible heart of your PV system.

The Sungrow SG4.0RT is the future-proof 3-phase string inverter for your residential photovoltaic system. It combines maximum efficiency, maximum planning flexibility, and comprehensive safety features in a compact housing. An investment that pays off.

Maximum yields thanks to two MPP trackers

The key feature of this inverter is its two independent MPP trackers . This makes it the perfect choice for more complex roofs, such as those with an east-west orientation or partial shade . Each string is individually optimized to maximize the possible yield from your system.

Everything in view: Wi-Fi & Ethernet on board

Monitor and manage the performance of your solar system conveniently and in real time. The included Wi-Fi dongle allows for easy integration into your home network. An Ethernet port is available for an even more stable connection. With the Sungrow app, you have all the data on your smartphone at all times.

Integrated security that saves costs

The SG4.0RT comes with comprehensive, integrated protection features. A DC disconnect switch and surge protection (SPD Type II) on both the DC and AC sides are installed as standard. This not only saves costs on external components but also saves valuable time during installation.

Important note on installation

Work on electrical systems may only be carried out by a registered specialist company. This particularly applies to connecting the inverter to the public power grid.
