DATASHEET - STUDER NEXT3Features
100% off+ongrid
A grid-tied solution, 100% offgrid. Full backup capabilities if required with peak power supplying any type of loads. Transfer switch integrated, no need of external backup setups. Compatible with other AC sources as generators. The grid is optional not mandatory.
AC flex
The unique AC flex interface can be configured as a second source or an extra controlled load.
All battery technology ready
The next3 is compatible with almost every 48V battery technology. An integrated CAN-BMS interface ensures a plug and play solution with communicating lithium batteries.
All-in-one with solar built-in
The next3 incorporates 2 high voltage MPPT inputs of last generation for a 16 KW integrated solar power.
next interface, the new gate to the next ecosystem using nextOS
With the inverter-charger, we have developed a new comprehensive interface. One single and central user interface per complete system. The next interface is the new gate to the next ecosystem using nextOS, an intuitive smart platform to configure, control and analyse your system. Making life easier for both professional installers and final users.
Compact for an easy installation
The installation and wiring have never been easier with only one device replacing up to 6 in a typical installation.
New improved smart boost function
The Smart Boost2 function helps adapting to the source limitations with the battery in the most versatile way, facilitating for example phase balancing or peak-shaving.
Rack 19” ready
The next3 is also available in 19” rack version for a smooth professional integration taking advantage of all the versatility of rack installations including complete solution integrating rack batteries, high index protection, controlled temperature among others.
Power flow dispatcher®, the brain of the whole system
System oriented, the new power flow dispatcher® centralizes the power management of the complete system integrally.
