SMA Solar Technology AG 3 Product Description
User Manual STP5-9TL-BA-en-10 11
3.2 Display
The display shows the current operating data of the inverter (e.g. current power, daily energy, total
energy) as well as any events and errors. The energy and power are displayed as bars in the
diagram.
The display values may deviate from the actual values and must not be used for billing purposes.
The values measured by the inverter are required for the operational control and to control the current
to be fed into the electricity grid.
