EXPECTED IN AUTUMN 2024
Next1
Next1
The new smart inverter-charger for off-grid and grid-tied applications a heritage of 35 years of experience. A single-phase smart inverter-charger with low frequency topology ensuring the highest overload capability and the minimum standby consumption for offgrid and gridtied applications.
Also available in 120Vac
The next1 will have 120Vac output version (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. Fully monitored connection for open possibilities: generator, EV charger, load management…
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/DC
The philosophy we are bringing to our Next1 rack is to work seamlessly with any solar inverters coupled on AC and/or our solar charge controllers coupled on DC for new or retrofitting installations.
Rack 19” ready
The Next1 rack version is available for 19” professional rack and batteries integration.
