Technical explanation
Different algorithms exist. Check each MPPT voltage range, maximum cold-weather voltage, permitted current and short-circuit current. Parallel strings on one MPPT need compatible voltages.

MPPTMaximum Power Point Tracker — dynamic optimization
TL;DR
MPPT tracks the maximum power point of a PV generator. Physical inputs may differ in number from independent trackers.
Definition
Maximum Power Point Tracking adjusts the electrical operating point to module conditions to seek maximum available power within inverter limits.

Swiss context
Request a string and MPPT plan for your roof. Multiple orientations may require separate trackers or another architecture; simulation and electrical limits must justify the choice.

FAQs — MPPT
How many MPPTs do I need for my installation?+
There is no universal count per orientation. The installer must check voltages, currents, shading and output curves for the exact inverter model.
Does the number of MPPTs impact the price of the inverter?+
Compare full quotes and simulated gains. An extra MPPT adds value only when sizing and roof conditions use it.
