Description
E_Total
kWh
0 ... 200000
0
Total energy yield (E_Total) and
total operating hours (h_Total) of the
inverter. Changing the value can be
necessary when a Sunny Boy is
exchanged and you wish to match
the previously acquired data.
h_Total
h
0 ... 200000

Vconst-Setval
V
500
PV Setpoint voltage for constant
voltage operation. These
parameters only are important in
case the parameter “Operating
Mode“ is set to “V-const“.
Vpv-Start
V
.8 ... 2x VAC
nominal
264 V @
240 V AC,
229 V @
208 V AC
Minimum DC voltage for the Sunny
Boy to connect to the grid. Set using
formula, for example, default value
for 240 is 1.099 x 240 = 264.
Formula can be adjusted from 0.8 to
2.0 x nominal V.
T-Start
s
5 ... 1600
10 / 300
The time the inverter waits to
connect to the grid after Vpv-Start is
exceeded.
This value defaults to 5 minutes after
a utility fault.
T-Stop
s
1 ... 1800
2
The time that the Sunny Boy waits to
disconnect from the grid when Pac
falls below 10W.

0 ... 100
50
Fan turn-off temperature
T-Start-Fan

0 ... 100
60
Fan turn-on temperature at
minimum rotating speed.
T-Max-Fan
degC
(°C)
0 ... 100
90
Temperature for maximum fan
rotation speed.
Fan-Test
1 / 0
0
By setting this parameter to “1“ you
can check the function of the fans.
This test turns the fans at maximum
speed.
