Energy management with the System Manager

SMA System Manager (Sunny Tripower X 25, Sunny Tripower X 60, Sunny Tripower Storage X, Data Manager M) have pre-defined energy management profiles. These profiles form the basis for configuring the energy management.

Functions:

• Import

  The battery is charged with excess energy from the PV system. If there is no excess energy available, the battery is charged from the utility grid.

• Export

  The available energy from the PV system is fed into the utility grid.

• 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 point of interconnection. This is mostly useful when a higher supply of energy would lead to a higher electricity cost. 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 and additional costs can thus be avoided.

  You can configure setpoints for the power drawn at the point of interconnection. When the loads require additional energy, the battery is discharged and the maximum value is kept constant at the grid-connection point. This is based on the prerequisite that the battery is sufficiently charged.

  During peak loads, energy from the PV system or battery is used to reduce the amount of energy drawn from the utility grid. A combination of increased self-consumption and peak load shaving can be set (multiuse).

• Maximum Increased Self-Consumption

  With increased self-consumption, the highest possible proportion of the power of a generator (e.g. a PV system) is consumed at the place where it is generated. With increased self-consumption, power output and power consumption at the point of interconnection are reduced. The inverter supports the increased self-consumption through intermediate storage of energy from generators.

  This operating mode is always active if no other mode has been selected. Self-consumption is maximized through intelligent charging and discharging of the battery, and feed-in to the utility grid is minimized. The operating mode cannot be used as a basis for configuring individual operating modes.

• Multiuse

  The multiuse function is a combination of increased self-consumption and peak load shaving. The total storage capacity of the battery is virtually distributed between increased self-consumption and peak load shaving. With this function, it is also possible to increase the self-consumption rate and save further electricity costs.

• Energy Management

  With the energy management function, you can adjust the charging behavior of the battery to your utility rate plan (electricity tariff). Energy bills can thus be reduced and electricity at lower cost can be used. You can set different operating modes depending on the time of day, day of the week, or season to optimize your battery usage. At specific times, this is mostly useful when the battery's state of charge has to take on a certain value or the rate plan makes the specific use of the battery more attractive.
