4 Product Overview SMA Solar Technology AG
unable to provide energy. When the black-start switch is switched on manually, the energy from the
auxiliary battery is made available in order to automatically switch the battery and therefore also
the inverter from sleep mode to operation in order that the inverter can make energy available from
the battery. You can stop the battery-backup operation by switching it off manually. To enable the
black-start function, at least one battery must be connected to input A.
Multi-battery device
The product is equipped with the multi-battery function as standard from firmware version
1.50.10.R. The multi-battery function enables to charge and discharge several batteries of the same
or different type. If the system is extended by one or several batteries or one battery is replaced,
the battery configuration must be reset and carried out again. The configuration is carried out via
the installation assistant on the user interface of the battery inverter. An overview of batteries
approved by SMA Solar Technology AG and their possible combinations is available at
www.SMA-Solar.com.
SMA Smart Connected
SMA Smart Connected is the free monitoring of the inverter via the SMA Sunny Portal. Thanks to
SMA Smart Connected, the PV system operator and qualified person will be informed automatically
and proactively about inverter events that occur.
SMA Smart Connected is activated during registration in Sunny Portal. In order to use SMA Smart
Connected, it is necessary that the inverter is permanently connected to Sunny Portal and the data
of the PV system operator and qualified person is stored in Sunny Portal and up-to-date.
Time-of-Use
With the "Time-of-Use" function, you can adjust the charging behavior of the battery to your
electricity tariff. Energy bills are thus reduced and electricity at lower cost can be used. You can
determine in which time range the battery with a specified charging power is operated. At specific
times, this is mostly useful when the battery's state of charge has to take on a certain value or the
tariff situation makes the charging more attractive, regardless of the power at the grid-connection
point. This means that the charging of the battery is independent from the power of the PV system
and energy consumption of the loads connected in the house. The charging parameters set in the
power profile are only limited by the state of charge (SOC). At times when the "Time-of-Use"
function is not activated, the battery is charged correspondent to the increased self-consumption for
the entire system. The "Time-of-Use" function is deactivated by default and must be activated by
creating power profiles.
Peak load shaving
With the "Peak Load Shaving" function, you can optimize the behavior of the battery inverter with
respect to the power exchange at the grid-connection point. This is mostly useful when a higher
supply of energy would lead to a higher electricity tariff. With the "Peak Load Shaving" function,
certain grid-exchange power outputs to which the battery inverter is adjusted depending on its
power and battery capacity available can be set. Power peaks can thus be avoided.
