Get Continuous Power with MidNite Solar and Fronius
A Powerful AC Coupling Pair  

Combine the efficiency of the Fronius GEN24 with the energy security of MidNite Solar!

Fronius and MidNite Solar are excited to announce that testing has been completed showing full compatibility between the Fronius GEN24 and Midnite Rosie, product number MNROSIE7048RE.

The Fronius GEN24 converts power from your solar panels into power you can sell to the grid with extremely high efficiency, allowing you the best energy offsets for your solar installation budget.  MidNite’s battery-based inverters offer power independence to support you during grid outages, but multiple energy conversions lower efficiency during your energy reset.

Pairing the MidNite Rosie Inverter AC Coupled battery-based system to your Fronius GEN24 string inverter allows for the best of both worlds! The efficiency of the string inverter allows for perfect self-consumption, while the AC coupled battery-based system gives you an option to connect a low-voltage DC battery to keep your lights on during critical-power conditions.  

What is AC Coupling?
AC coupling allows a battery-based inverter to charge batteries and power your home with the power from a grid tied inverter during a grid failure.  It does this by providing a voltage signal to the grid tied inverter, so it continues to make power as if the grid was still present. Your batteries will be charged from the battery-based inverter, ensuring that your system is operating with maximum runtime.

Advantages of AC Coupling
  
·       Easy to retrofit into existing systems
         ·       No need to add a separate solar array
  ·       Supports future expansion of battery based or string inverter system
