ENmismatch loss 
a) inverter mismatch loss

(Unit: W or dimensionless and expressed as a percentage, %)

power loss produced when a power conditioner is operating at a different input voltage or electric current from the voltage at the maximum power point or the electric current at the maximum power

b) module mismatch loss

(Unit: W or dimensionless and expressed as a percentage, %)

difference between the total maximum power of PV devices connected in series or parallel and the sum of each device measured separately under the same conditions

NOTE PV module mismatch loss arises because of differences in individual device I-V characteristics
