Frequently asked questions
What is the SMA Sunny Boy SMArt Energy 4.0?
The Sunny Boy SMArt Energy 4.0 is a single-phase hybrid inverter from SMA with 4.0 kW AC rated power. It converts the solar power from your PV modules and can be directly combined with a battery storage system to temporarily store surplus energy for self-consumption.
Which systems is the Sunny Boy SMArt Energy 4.0 suitable for?
It is suitable for single-phase PV systems in single and two-family homes with up to 8.0 kWp DC connection power. With three MPP trackers and integrated shade management, even differently oriented or partially shaded roof areas can be used efficiently.
Can I connect a battery storage system?
Yes, the SMArt Energy 4.0 is a true hybrid inverter and supports both AC and DC battery coupling with up to 30 A charging current and a charging voltage of 90-500 V. This allows a suitable storage system to be connected to increase self-consumption. This model does not offer a backup power function.
How many MPP trackers does the device have?
The inverter has three independent MPP trackers, each with 15 A input current, and a total of three string inputs. This allows for flexible distribution of the module strings across multiple roof areas.
Who is SMA?
SMA is a German manufacturer of inverters and energy management solutions based in Niestetal. The company is one of the most established providers in the photovoltaic industry and manufactures the Sunny Boy SMArt Energy in Germany.
