Using only 4 out of 6 MPPTs

[Raj2510]

Hi,

I am simulating a system with 10 inverters that have 6 balanced MPPTs each. The problem is that my design only requires the use of 4 MPPTs from each inverter.

Note: All string sizes are same.

How to I go about simulating this?

If all your strings are identical (same number of modules in series), you should uncheck the case "Use multi-MPPT feature". The simulation will consider each inverter as a whole and will not share the Pnom on the MPPT inputs.

Another way is to redefine your inverter as a 4-MPPT input device.
