IP65 for use in all possible environments.
Designed, assembled and tested in Switzerland.
Install once and profit for a decade thanks to high-quality components.
Pure sine wave
Off/on-grid inverter 6500VA/4500VA.
Full backup power.
Unstoppable peak power of 12kVA/10.5kVA for 5 seconds.
10-year warranty
No worries about environmental conditions
The next1 is designed to withstand even the most demanding environments and works perfectly whatever the conditions: – Intense heat – extreme cold – high humidity
The next1 delivers 80% of its rated power at 45 °C and operates at up to 60 °C.
Thanks to IP65 protection, it withstands rain, dust and up to 100% humidity, ensuring reliable operation in any environment. This inverterkeeps working without compromise, wherever your installation is located.
Made in Switzerland 
Designed, assembled and tested in Switzerland, ensuring the highest standards of quality and reliability. Every unit passes strict inspections to ensure exceptional performance, long-term durability and seamless operation in even the most demanding environments. Thanks to Swiss-made excellence, you can trust the next1 to deliver a perfect sine wave and reliability for years to come.
A perfect, pure sine wave
The next1 produces an exceptionally pure sine wave, making it ideal for applications that require a flawless signal.
This level of precision is so high that some of our customers use Studer inverters off-grid in recording studios to eliminate electrical noise and interference from a poor grid and ensure uncompromised sound quality thanks to the brilliant sine wave.
Unstoppable peak power of 12kVA for the nx1 6500-48 for 5 seconds.
Built to power all loads, such as pumps, compressors and more. Inrush currents and power peaks go unnoticed, perfect for off-grid applications.
Power flow dispatcher®
The system-oriented Power flow dispatcher®is our AI algorithm that coordinates energy management across the whole system. It gives you the best possible control of energy production.
From now on, everything is included in the next1.
nextOS, our operating system for configuring, controlling and analysing the system, is integrated directly into the unit, so no external control display is needed. The nx-interface is still available as an option if your customer wants a physical display interface.
The user interface can be accessed via the internet.
Built-in connections: Access Point, WLAN and Ethernet, web interface, CAN BMS, Modbus RTU/TCP, USB and much more.
Easy monitoring and configuration via the app
The Studer monitoring app, designed for tracking system data, is perfect when you want information about your system at a glance. It lets you connect directly to the next1 web interface from your phone via your WLAN. All data is stored on European servers.
With this app, installers can easily install and configure the next1 using their phone. By following the app’s built-in wizard, you are guided through the whole procedure from connecting the device to the WLAN access point to final commissioning.
Open up home automation integration possibilities
I/O: mini home-automation possibilities without extra devices. With these physical contacts on the next1, you can switch on specific devices according to conditions set in the inverter configuration. No external home automation system needed.
For more complex systems you can use the open Modbus/API ““Open Studer”, which allows next1 units to be fully integrated into complex and customised system architectures.
