james Posted August 29, 2018 Report Share Posted August 29, 2018 I have a sawtooth roof which has three usable areas of the same azimuth and slope and are defined as different areas in the software. Each roof area has a whole number of strings of modules. I'd like to use a Fronius 27kW with 1MPPT and 5 strings. Some inverters will have strings from different roof areas. I have selected the three roof areas and selected 'Configure module areas together'. I get an error when I try and select the Fronius 1MPPT inverter 'This manufacturer has no inverter with more than 2 MPP tracker. Choose another manufacturer or polystring wiring'. What is the solution to allow this design? Thanks Quote Link to comment Share on other sites More sharing options...
