- Regulation loss is the energy potentially available from the PV array, but which cannot be used by the system. In MPP applications, this could be the array potential PV production outside the inverter input voltage limits, or during power overloads. This is usually accounted in "Inverter losses", that is in system losses.

Operating conditions for current limiting losses. The Current limiting loss is very often "preceded" (i.e. masked) by the overload loss. Remember that when the Pmpp is outside the colored limits, the operating point is shifted on the I/V curve of the array, up to its intersection with a limiting line (see Pmpp => POper), i.e. towards higher voltages, and therefore lower currents.
