Dynamic Feed-in Control

 sub-menu it’s possible to enable 

the 

management of power flows in order to optimize self-consumption or 

avoid feeding power to the grid (except during transitory), basing on the 

reading of the energy meter:

No UL meters are available at the moment. The selection of the meter must be “None”

- 

  

Meter: 

When a meter device is connected to the inverter, it’s 

requested to select the meter model: 

1. 

None

 (where system is installed without meter) 

2. 

REACT-MTR-1PH 

(single-phase). Not UL certifified.

 

3.
