SB3800U Operating Parameters
CAUTION: The changing of operating parameters should only
be performed by qualified personnel. Changes to factory preset
parameters may adversely effect inverter operation and perfor-
mance.

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 0
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.
T-Stop-Fan degC
(°C) 0 ... 100 50 Fan turn-off temperature
T-Start-Fan degC
(°C) 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.
