If you have panels facing different directions then - as a general rule they should be on separate strings each with their own inverter input (MPPT).
Most inverters have 2 inputs. So if you have panels facing more than 2 directions you should either use:
- Microinverters
- DC Optimisers
- Maxim Panels
Or an inverter with enough MPPT inputs for each roof orientation.
Or if two of your orientations are East/West with the same amount of panels on each face, some inverters can handle a symmetrical East/West installation on one inverter input.
