v1.5.0

New Features

Peak shaving control point can now be configured within the peak shaving operation mode template

Users can now define different control points for each Peak Shaving operation mode. To do this:

• Navigate to Operations Management.

• Create a new task of type Peak Shaving.

• Specify the desired control point (e.g. 30 kW) in the designated input field

• Save the task

Important Notes:

• Pre-existing modes: All existing Peak Shaving operation modes will default to the control point defined under System Settings → Grid Connection Point.

• EVCS Load Management Limit: The control point under System Settings → Grid Connection Point remains the upper limit for EVCS Load Management.

• Multi-Use operation mode: The integration of control points into the Peak Shaving template is not yet available for the Multi-Use operation mode. In this mode, the global control point still applies as both the EVCS Load Management limit and the Peak Shaving control point.

This update gives you greater flexibility to tailor Peak Shaving to your specific operational needs

New Device Integration: SMA Data Manager M

The SMA Data Manager M can now be used within the EMS as a smart meter, specifically for photovoltaic systems. Within the EMS, it functions like any other smart meter for PV. Power and energy readings from the device are being displayed in various areas of the EMS where photovoltaic data is relevant: Dashboard, Reports, Photovoltaic (Overview, Details, Reports).

Notifications for inverter and BMS errors

EMS users will receive notifications for inverter and BMS errors within the UI as well as via email.

Daily energy values displayed next to the legend in the Overview chart

EMS users are now able to see the daily energy values displayed next to the legend in the Reports > Overview chart for the following data points:

• Grid consumption

• Grid feed-in

• Charging

• Discharging

• PV production

• Consumption

• EVCS

The values for Grid feed-in, Grid consumption, PV production, and Consumption will continue to be displayed if the user selects Month, Year, or Overall reports.

Please note that these values are refreshed hourly.

Please refer to the sample screenshot below for reference:

Changes

REST API (Cloud + local): Control endpoint updated

The Control endpoint has been updated so that:

1. If a charge request exceeds the maxChargeLimit, the system charges at the maxChargeLimit and counts the request as valid, extending the 5-minute period for further requests.

2. If a discharge request exceeds the maxDischargeLimit, the system discharges at the maxDischargeLimit and also counts the request as valid, extending the 5-minute period for further requests.

Allow to enter a TCP port for TCP connected devices over UI

When a TCP connected device is being created or updated in the EMS, the user can now enter a TCP port number under the Interface section in order to be able to add devices which do not operate on the standard port.

See below image for reference:

Enhanced mobile views for pages: Dashboard, Notifications and Devices

The Dashboard page, when used on a mobile device, has been updated to show the energy monitor, similar to the desktop version. See screenshot below:

The Notifications and Devices pages have been also updated to better suit the mobile device screen size. Please see the below screenshots for reference:

Notification types

The Notifications page now displays the type of the notification which are either:

• Error

• Warning or

• Information

Until this change, every notification was of type “Information”.

Carlo Gavazzi smart meter setup - Note

The below note appears when a Carlo Gavazzi smart meter is created. Without setting the proper application within the settings of the device, the functionality of the meter readings cannot be assured.

Reports show only PV values higher or equal to zero

In the Reports section, the charts have been revised to display only PV production values that are zero or greater. Any values that were previously negative will now be represented as zero.

Bug fixes

Alpitronic HYC EVCS - energy data values corrected

The Alpitronic HYC EVCS data has been updated for accuracy, with a correction factor of 10 applied. As a result, the values displayed in the Reports and Charging Stations sections for Alpitronic HYC EVCS will now reflect the correct figures.

Example:

EnerCharge EVCS - energy data values corrected

The way energy data from EnerCharge EVCS is read from the devices has been corrected. As a result, the values displayed in the Reports and Charging Stations sections for EnerCharge EVCS will now reflect the correct figures.

Inverter details: grid frequency shown with decimal places

The display of grid frequency value, under Storage > Inverter details has been updated to have two decimal places. Before this change, the value was displayed without the decimal places.

Autarky set to 100 on negative load

Before this change, when the load value was negative, the autarky was displayed as zero. Now, when the load is negative, autarky is 100%, this being visible on the dashboard.

v1.3.9

New Features

Local Modbus TCP interface

The EMS offers the capability to interact with the PSEC via a new local Modbus interface. This feature allows reading and writing certain registers. For details, please refer to the technical documentation.

In order to offer an enhanced user experience when interacting with the EMS for setting up local interfaces, the previously named Local API tab under System Settings > IT Network is now called Local Interfaces and it presents information and options on the preexisting Local REST API as well as the new local Modbus interface. The information and the controls for the REST API have not changed. A new sub-section was added for information and controls on the Modbus interface. In order to use this interface for reading registers, the Read access toggle needs to be enabled. In order to use this interface for writing registers, the Write access toggle needs to be enabled and current operation mode must be External Control.

The page now looks like in the screenshot below:
