Commissioning prerequisites

The following points need to be checked to have a successful, efficient, and quick commissioning:

  1. Carefully read safety instructions on the product user manual.
  2. The power supply of all the devices needs to be taken from the load side. (applicable for the UPS as well)
  3. Modbus RTU :Shielded twisted cable must be used for RS485 wiring : The data+ and data- should be chosen from the same twisted pair in order to prevent electromagnetic interference. The ground should be chosen from another pair.
  4. Modbus TCP : RJ45 Ethernet cable for TCP wiring.
  5. RJ45 cable and a Computer with a configured Ethernet port in DHCP mode are needed to access the Elum configuration tool (eConf).

Please, refer to the commissioning prerequisites document for more details.

Wire and install the controller

ePowerControl ZE should be installed on a DIN rail.
To avoid the Central Computing Unit overheating, consider a 15 cm cooling area on each side of it.

The power supply connector is on the top of the device.
Grounding and wire routing help limit the effects of noise due to electromagnetic interference.

It takes about 30 seconds for the system to boot up.
Once the power supply is connected, the power LED will light up.
After 60 seconds, the operating system will be ready, and the power LED will turn solid green.

Wire and configure slave devices

Modbus RTU : 

Compatible RS485 devices can be connected to serial ports of the ZE Central Computing Unit using two shielded twisted pair connectors.
Please use a surge protection to avoid any issues on the communication ports.
Please refer to the connect & config guide for more details on how to connect and configure your device.

Modbus TCP :

Compatible Ethernet devices can be connected to the LAN port 1 of the ZE500 and ZE1000, and LAN port 1, 2 and 3 of the ZE3000 using a RJ45 cable.
Please use a surge protection to avoid any issues on the communication ports.
Please refer to the connect & config guide for more details on how to connect and configure your Device.

For both cases, please make sure to enable the dynamic power control of the PV inverters when applicable, and to set the Current transformer ratio, the Voltage transformer ratio as well as the system type for the meters.

EMS configuration
  1. Connect your laptop to the configuration port of the ZE:
    •  LAN port 2 for the ZE500 and ZE1000,
    • LAN port 4 for the ZE3000.
  2. Open your favorite browser, and login to eConf by entering the following IP address: 192.168.4.127
    (the Ethernet port of your computer should be configured in DHCP mode.)
  3. For the next steps, follow the demo below :

FAQ ePowerControl ZE

Yes, in addition to the zero export, our controllers include both the minimum import and maximum export features.

Yes, all of our controllers have the grid feed-in management feature, which includes the maximum export to the grid option. The controller aims to set the active power export target (configurable) at the grid connection point when dispatching PV production.

Yes, all of our controllers have the grid feed-in management feature, which includes the minimum import to the grid option. The controller aims to set the active power import target (configurable) at the grid connection point when dispatching PV production.
The controller monitors the load and curtails the right amount of solar power to enable a maximum PV production, while ensuring zero export to the grid, thus avoiding penalties from the grid operator.
It is possible to add a load meter to the configuration, but it is not required.
In order to avoid all issues, it is highly recommended to use bidirectional meters, particularly for grid meters, to allow positive and negative measurements.

The controllers curtail the PV production by sending setpoints to the PV inverters to control “Wmax”, which is the Modbus register of the inverters that allows remote control of the active power limit setpoint.
Depending on the installation and on the type of the EMS chosen by the user, the controller retrieves measurements from the slave devices, and dispatches the setpoints accordingly.

The fail safe mode describes the behavior of the controller when the communication with one of the critical elements composing the installation is lost, and the usual observations of the control strategy are therefore uncertain. The PV production is ramped down to 0 as long as the communication is lost.

The critical elements are : grid meters, PV inverters, bess inverters, genset meters and genset controllers.

ePowerControl solution offers controllers that include the data logging feature by default.
