Use the NREL website 3 to download the database of inverters. Choose a random inverter and apply the SNL
model 4 to calculate the efficiency of the inverter. Plot P AC = f (P DC ) and η = g(P DC ) for three V DC levels. You
may assume:
P DC = [0, step, 2 × P DC0 ]
V DC = [V DC(MPPTlow) , V
DC(MPPT
high)
].
