Context

Industrial and commercial (C&I) buildings located in geographies with a good quality grid connection nowadays wish to benefit from solar energy to reduce their energy supply costs.

 

When a solar production capacity is added, several issues are essential for the monitoring and maintenance of the site:

  • Anomaly detection on the scale of a portfolio of self-consumption sites
  • Prohibition of injection of solar surplus to the grid (regulation present in several geographies)
  • Interfacing with DEIE box with EDF (France and DOM)

 

A monitoring and control system is therefore essential to maximize the yield of a solar power plant in operation and to comply with local solar injection legislation.

Elum's solution

ePowerLog DL and ePowerControl ZE and ePowerControl PPC DEIE are Elum Energy’s monitoring and control solutions that connect to the solar inverters (RS485/TCP), the grid and the site load (via meters). 

These solutions automatically monitor and control the output power of the PV inverters according to the country’s feed-in regulation constraints. These solutions are compatible with all Modbus-capable inverters on the market.

Key elements

Extensive compatibility with the leading inverter suppliers on the market  

Simple and intuitive eConf configuration menu allowing configuration and start-up of the controller in a few hours.

The ePowerControl solutions are also dataloggers allowing data feedback

ePowerControl PPC communicates with the DEIE box supplied by EDF to control the relays

ePowerControl ZE ensures the limitation of feed-in to the national grid in case of solar overproduction

The ePowerMonitor web platform allows to remotely monitor the status and consumption of the site’s equipment in order to ensure its performance and facilitate its maintenance via a personalized alarm management
