One MPPT 2 strings with slightly different tilt.

[Bendesa1962]

Hi All,

Most Grid Tied Commercial Inverters has multiple MPPT trackers. Each MPPT Tracker can be connected with 2 Strings.

What would be the disadvantage if we connect two strings (same PV Modules same number 18 x series) with slightly
difference in tilt?

The difference in tilt will not be more then 3 Degrees

What is your opinion about this?

Many thx in advance

Kind regards

Ben

Not a problem. The voltage on a string varies little with orientation. Mostly the amps change as the sun moves across the sky. Its a common practice to parallel strings that are different tilts.
