Next3 - Inverter Charger with 2 Built-in Solar High Voltage MPPT Trackers
The special price is valid for orders placed, paid for and delivered before 30 September 2025 and applies while stocks last >>> first come, first served!The Studer Next1 and Next3 are uniquely functional and powerful hybrid inverters for off-grid, on-grid and hybrid systems.
The Next3 combines the advantages of a special hybrid inverter with an AC charger and PV charge controller in a single device.
With a continuous output of 15 kVA and a peak output of up to 30 kVA, it can supply any type of load, whether connected to the grid or completely independent of the grid. It has two latest-generation 900V high-voltage MPPT inputs with ultra-fast MPP tracking for PV power of 2 x 8 kW.
It can work with all battery types and offers high efficiency and flexibility.
With the next Interface, the new gateway to the next ecosystem with nextOS, you can easily configure, monitor and control the next3. The next3 sets new standards in hybrid inverter technology and offers you a reliable, intelligent and sustainable energy solution.
This 10-year manufacturer's warranty applies specifically to all Next hybrid inverters, guaranteeing you the quality and durability of the product, and is one of the longest on the market. You can rely on the service and support of Studer Innotec, a leading manufacturer of energy solutions in unique industrial quality since 1987.
If you want even more security, you can book the optional studercare+ warranty extension. With studercare+, you receive comprehensive protection against defects and damage for up to an additional 5 years on top of the standard warranty. In addition to repair or replacement of the device, the warranty extension includes professional service with a straightforward return policy. Studer care+ repairs are given priority.
