Settings in the KOSTAL Smart Energy Meter
1. RS485 interface
By default, no changes have to be made to the RS485 interfaces.
These arrive preconfigured.
The following devices can be connected to the RS485 interfaces:
- RS485 interface (A): PLENTICORE plus / PLENTICORE BI
- RS485 interface (B): PIKO MP plus
If changes are to be made to the settings, perform the following steps:
- Call up the KOSTAL Smart Energy Meter's online interface
- Call up Modbus configuration under Modbus settings.
- Select PIKO IQ/PLENTICORE from drop-down list.
- Press the Save button to adopt the settings.
- Settings for the RS485 interface (A) have been completed
INFO
When an inverter is selected, the predefined default values are adopted. These can be adjusted if necessary.
If a PIKO MP plus is to be added as a PV inverter, the slave interface B must be deactivated.
Parameter | Value |

2. Adding KOSTAL inverters in the KOSTAL Smart Energy Meter
If you want to monitor the power at the grid connection point or use the dynamic limitation of feed-in capacity, all KOSTAL inverters present in the device network must be set up in the KOSTAL Smart Energy Meter.
INFO
If power specification via ripple control receivers is required for the system in question, please do not add the inverters to the KOSTAL Smart Energy Meter under any circumstances!
Instead, configure the use of the ripple control signals in the KOSTAL inverters. You will find more detailed information in the relevant operating manuals.
All KOSTAL inverters present in the device network must be set up in the KOSTAL Smart Energy Meter.
To do this, proceed as follows:
- Call up the KOSTAL Smart Energy Meter's online interface
- Go to Inverter > Devices (manage the inverters used).
- Use the plus symbol to add an inverter.
- Add more inverters using the same function.
- Press the OK button to adopt the settings.
- The inverters have been set up in the KOSTAL Smart Energy Meter.
INFO
When an inverter is selected, the predefined default values are adopted. These can be adapted if necessary. Further information on the set up can be found in the operating manual for the KOSTAL Smart Energy Meter.
Parameter | Value |
---|---|
Series | Select inverter series |
Category | Select here whether a battery is directly connected to the inverter (PLENTICORE). |
IP address | Enter the inverter's IP address. The IP address can be read on the inverter’s display. |
Maximum output power | Enter the inverter’s max. output power. This is required if a power limitation is to be set and calculated at the grid connection point. |
Open advanced settings | |
Unit ID | The unit ID does not have to be changed |
3. Setting the feed-in capacity limitation for the grid connection point in the KOSTAL Smart Energy Meter.
A dynamic limitation of the feed-in capacity/feed-in limitation for the entire system measured by the KOSTAL Smart Energy Meter (e.g. to 70 % of the total output) can be set by going to Plant overview/Settings > Settings (cogwheel) > Power limitation. If this is necessary for your system, proceed as follows.
The power limitation monitors the feed-in of the entire system. If the value set for the feed-in limit is exceeded, the KOSTAL Smart Energy Meter calculates the amount by which each connected inverter needs to reduce its output to avoid exceeding the feed-in limit. The maximum output power value set for each individual inverter provides the basis for calculating the amount by which the inverter needs to reduce its power.
To do this, proceed as follows:
- Call up the KOSTAL Smart Energy Meter's online interface
- Go to Plant overview/Settings > Settings (cogwheel) > Power limitation Power limitation.
- Activate power limitation (1).
- Enter a value for the power limitation (2). The calculator function (3) can be used for the calculation. Here you can enter e.g. 70 % and the power limitation will be calculated automatically based on the values entered.
- Important: If a battery storage unit is being used in the system, the feed-in capacity can be limited to up to 50%.
- Press the Save button to adopt the settings.
- The power limitation has been set up in the KOSTAL Smart Energy Meter.
