There are 4 icons that are also labeled on the
left side pane of the page.
• Status - shows the overall flow of power for the
storage system and associated components.
• Control - not used in the U.S. Future develop-
ment.
• History - displays system data in an easy to read
graph. Can display data in various time formats.
• Forecast - shows past production and consump-
tion data and predicted PV production and con-
sumption data. This data is for display purposes
only and does not influence the charging/dis-
charging behavior of the storage system.
• Downloads - allows user to gather various data
in a spreadsheet compatible format.

This display shows 5 key pieces of information
regarding where the power is going in the entire
system using yellow line indicators:
• Production - indicates the amount of power
the PV system is producing as measured by the
storage system.
• Consumption - a measure of how much power
is being consumed by the loads the storage
system is supplying.
• Feed-In - the amount of excess PV that is
passed through the storage system towards the
utility.
In this example, you are looking at an eco unit
running in self consumption mode AC coupled
with an 8kW PV system. It is early in the morning
and the solar is producing 1.6kW of power. There
is also 300W (.3kW) of consumption by the loads
that are being fed by the storage unit. Since
there is more solar than load, 300W of the solar
production is consumed by the loads and the
remaining 1.2kW is then fed to the sonnen to
charge the batteries. We can see that the Charge
value (light blue) is 1.2kW and the current state of
charge is 17%.
There is a small amount of excess PV
(100W) that is being fed into the grid.
It is important to understand that the
sonnen eco unit only gets the excess PV that is
left over after feeding the loads on the panel
that is downstream of it. If this customer had a
larger load turned on, such as an electric stove
that requires 2000W of power, the 1.6Kw of
production would all be consumed by the stove
and either the storage unit or the grid would have
to supply the other 400W.
