SB3800U-12:SE2006 SMA America 7-5
Normal Operation
The inverter is feeding the utility grid in either “MPP”, “Constant Voltage” or “Turbine”
mode.
“MPP” Mode:
The SB3800U adjusts the voltage and current from the PV array to obtain
the greatest PV output power.
“Constant Voltage” Mode:
The voltage from the PV array has been set to a fixed value.
This value is set by using the Sunny Boy Control or the Sunny Data software. (The
parameter name is “V-Const”) This mode is typically used for fuel cell or micro-hydro
applications.
“Turbine” Mode: This mode is used for DC rectified motor sources with a dynamic
power curve (typically wind turbines). The user can set the magnitude and slope of the
curve to match a particular alternator.
Derating
The SB3800U is designed to operate at full rated power up to 45
°C ambient
. The
inverter will continue to operate beyond 45°C and will derate as required to maintain
safe internal component temperatures. Unnecessary derating can also be caused by
blocked fan intakes. For this reason the fan intakes should be inspected often and
cleaned when necessary.
