Onduleur hybride 3kW - injection réseau - stockage. Augmentez votre autoconsommation 

 

High efficiency

  • Accurate real-time MPPT algorithm for maximum power generation
  • Wide operating range of the input voltage
  • Independent MPPT double tracking, flexible solar roof system design.

 

Reliable and safe

  • High efficiency, low energy loss, low maintenance
  • High frequency isolation between battery and PV network
  • Advanced battery management technology to protect battery life

 

Easier operation

  • Free choice of site thanks to the IP65
  • Clear and easy-to-read 4' LCD screen
  • Easy monitoring on phone (APP) and PC (web)

 

Multiple modes of operation

  • PV and all-in-one storage, increases self-consumption to more than 80%, decreases dependence on the electricity grid and reduces the electricity bill.
  • Autonomous mode (like UPS) available, ensures safe operation of critical loads.
  • Selection of several operating modes: automatic mode, usage time mode, timeout mode, passive mode, etc.

 

Intelligent network management

  • Reactive power capacity
  • Limits AC output when the network frequency is too high or too low.
  • Limits AC output when the network voltage is too high.
  • Built-in zero export function (optional)
