Frequently asked questions
What is the SMA STP 4.0-3AV-40?
The SMA STP 4.0-3AV-40 is a grid-tied, three-phase PV inverter with 4000 W AC rated power. It converts the direct current from the solar modules into grid-compliant alternating current and features two MPP trackers and a maximum efficiency of 97.2%.
Which systems is the STP 4.0-3AV-40 suitable for?
With 4.0 kW three-phase feed-in, the device is suitable for small to medium-sized rooftop PV systems in private homes. Thanks to two independent MPP trackers, two roof areas with different orientations or inclinations can be operated separately.
How many MPP trackers does the inverter have?
The STP 4.0-3AV-40 has two MPP trackers and operates with a maximum DC input voltage of 850 V. This allows two module strings to be operated independently at their optimal operating point.
What communication interfaces does the device offer?
Integrated TS4 communication, Ethernet, WLAN, as well as SMA Speedwire/Webconnect and MODBUS TCP with SMA and SunSpec profiles. This allows the inverter to be easily integrated into monitoring and energy management systems.
Who is SMA?
SMA Solar Technology is a German manufacturer of inverters and system technology for photovoltaics. The Sunny Tripower series is one of the established solutions for grid-tied solar systems.
