EXPECTED IN 2024
next1
next1
The new smart inverter-charger for off-grid and grid-tied applications. A single-phase smart inverter-charger with low frequency topology ensuring the highest overload capability and the minimum standby consumption.
Also available in 120Vac and UL compliant
The next1 will have 120Vac output version meeting the UL standards (coming soon).
Battery compatibility
The next1 incorporates our flexible battery profile options, compatible with lead-acid and Li-ion batteries. Ask our team for other battery technologies.
AC flex
The unique AC flex interface can be configured as a second source or an extra controlled load.
Power flow dispatcher®, the brain of the whole system
System oriented, the power flow dispatcher® centralizes the power management of the complete system integrally.
Full interactive grid inverter
Including an AC source with double disconnection relay with the grid. This input complies with the latest grid-tied regulations in the UE and other regions.
Solar AC
The next1 works smoothly with solar inverters coupled both on the AC loads and/or AC flex ports.
Rack 19” ready
The next1 rack version is available for 19” professional rack and batteries integration.
nextOS, the gate to the powerful next ecosystem
nextOS is an intuitive smart platform to configure, control and analyse your system. Making life easier for both professional installers and final users.
