10.5 Efficiency
The operating efficiency is shown for the three input voltages (V
mppmax
, V
dc, r
and
V
mppmin
) graphically. In all cases the efficiency refers to the standardized power
output (P
ac
/P
ac,r
). (According to EN 50524 (VDE 0126-13): 2008-10, cl. 4.5.3).
Notes: Values are based on rated grid voltage, cos (phi) = 1 and an ambient
temperature of 25
℃
.
