Voltage at maximum power. This is the specific voltage level on a photovoltaic module's current-voltage curve where the product of current and voltage yields the highest wattage. Solar charge controllers use maximum power point tracking algorithms to continuously adjust the load and keep the array operating exactly at Vmp as sunlight and temperature change.
Heard on the job
The string inverter is clipping because the array's Vmp dropped significantly as the panels heated up in the midday sun.
