Fronius Symo GEN24 10.0, Руководство по эксплуатации, Страница: 95 / 120

Example
Fronius inverter 6000 W (max. output power)
BYD Battery-Box Premium HV
defined discharge 6000 W
PV power 1000 W
In this case, the inverter would have to reduce the PV power to 0 W, since the output
power of the inverter is max. 6000 W and the device is already being used to capacity by
the discharging.
Since it doesn't make sense to waste PV power, the power limit is automatically adjusted
in the battery control specifications such that no PV power is wasted. In the example
above, this means that the battery is discharged only at 5000 W, so that the 1000 W PV
power can be used.
Load manage-
ment Priorities
If additional components (e.g. battery, Ohmpilot) are present in the system, the priorities
can be set here. Devices having higher priority are actuated first, and subsequently, if
there is still excess energy available, the other devices.
Load management
It is possible for up to four different load management rules to be defined. At the same
threshold values, the rules are activated in succession. For deactivation, this is done in
reverse; the I/O last switched on is the first to be switched off. In the case of different
thresholds, the I/O with the lowest threshold is switched on first, followed by the second
lowest, and so on.
I/Os controlled by the produced power are always prioritised over a battery and Ohmpi-
lot. That is to say that an I/O can switch on and result in the battery no longer being
charged or the Ohmpilot no longer being activated.
An I/O is activated or deactivated only after 60 seconds.
Control
- Control is deactivated.
- Control is effected by the power generated.
- Control is effected by excess power (given feed limits). This option can only be
selected if a meter has been connected. Control via Energy Manager is effected
using the actual power of feeding in with respect to the grid.
Thresholds
- On: For entering an effective power limit, at which the output is activated.
- Off: For entering an effective power limit, at which the output is deactivated.
Runtimes
- Field for enabling a minimum duration for which the output is to be activated for each
switch-on process.
- Field for enabling the maximum runtime per day.
- Field for enabling a target duration for which the output is to be activated in total per
day (total of several switch-on processes).
