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 25ā.
