New dynamic power controller with demand management

In recent years, CIRCUTOR has developed some of the most innovative and advanced solutions in the sector of photovoltaic self-consumption in Spain, leading initiatives and movements to facilitate the legalisation of installations interconnected to the grid for self-consumption with zero injection.

This has enabled CIRCUTOR to position itself as the company that offers the widest range of solutions in the Spanish market and with the most flexibility of control.

The range of CDP solutions from CIRCUTOR also enables a phase-by-phase control of the installations in order to take maximum advantage of the performance of the inverters. CIRCUTOR is reinforcing its commitment to offer solutions for photovoltaic self-consumption to the market, and is thus complementing its range of dynamic power controllers (CDP) by offering more options to manage the distributed generation of energy in the most efficient way.

As the icing on the cake to bring the year 2014 to a close, CIRCUTOR is launching the CDP-G on the market, the new Dynamic Power Controller with demand management. With this unit, a controlled injection to the grid can be guaranteed (or injection to the grid can be prevented, as in Spain's case). At the same time, maximum advantage can be taken of solar radiation surpluses for use in electrical consumption in installations.

The CDP-G incorporates all of the features of the CDP-0 and also includes new functions, making it a very flexible unit, in particular for use in the domestic and tertiary sector.

Some of the main features of the CDP-G are:

  • Capacity to control inverters from the leading brands
  • Use of surpluses of photovoltaic production
  • Monitoring via web (smartphone, tablet or PC)
  • Screen that shows consumption data, PV production, grid consumption and activation of manageable loads
  • Modbus/TCP communications for integration in SCADA

This makes it the ideal unit for optimising a photovoltaic energy installation for self-consumption in applications such as:

  • Managing heat pumps
  • Heating water with the use of thermal accumulators (swimming pools, homes)
  • Water pumping and irrigation applications
  • Production of compressed air

In this way, CIRCUTOR continues to be the leader in the sector of photovoltaic self-consumption with the most technologically advanced solutions on the market, thus offering better products to their customers.

Audits in Energy Efficiency European Directive: an obligation for companies and an opportunity for the sector

European Union Directive 2012/27/EU of 25 October 2012 sets a deadline of 5 December 2015 for all companies in member countries to carry out independent energy audits by qualified and/or accredited experts.

This Directive is binding in all member countries, and the administrative penalties for not performing energy audits on time can range from €300 to €100,000, in addition to other civil or criminal liabilities.

  • How can we ensure our installations are in compliance with the Energy Efficiency Directive?
  • Benefits of the European Directive for companies and the economy

Reinventing power factor compensation

An important factor, often not considered when compensating, is the actual imbalance of the loads. The use of compensation systems, measuring in a single phase and only compensating with three-phase capacitors, may overcompensate the system, achieving the opposite to the desired result of improving the power factor and losses in the distribution systems.

All this added to the extension of electronic energy meters (smart meters), which can individually register consumption per phase, and new types of penalty that include penalties for capacitive energy consumption, has led us to reinvent once again the traditional power factor correction systems.

CIRCUTOR presents its new range of OPTIM HYB batteries, capable of performing power factor correction processes based on an actual three-phase measurement of the system (measurement of the three phases instead of one) and thanks to combining single-phase capacitor compensation (P-N) with thyristors and three-phase capacitor compensation (III) with contactors, we are able to perform individual, fast and accurate compensation for each phase.

Energy Efficiency seminar in Malaysia

On 20th November, CIRCUTOR organised and participated with its official distributor in Malaysia in a seminar on the implementation of an energy efficiency system and its impact on the certification to ISO50001 for the optimisation of energy use in any organisation.

50 representatives of companies from different sectors of the country attended the event, which focused on the distribution of the POWERSTUDIO energy management software as a base for knowledge and savings in different production processes. In fact, the representatives of large consumers of energy, such as steelworks and cement works, attended the event and saw how CIRCUTOR can associate these consumptions with productivity rates and, as a result, achieve a positive impact on results, while reducing their contribution to the generation of greenhouse gases.

Consulting and engineering firms and manufacturers of other sectors, such as the food sector, could also see for themselves how we used the network to access energy management systems implemented in other countries from Kuala Lumpur; these systems had self-consumption or electric vehicle charging management solutions that provided an added value to systems, one of the highlights for participants during the session.

The event was closed after presentation of our flagship units, which provide information to this system, and our view of the market, which is particularly sensitive to the penalties applied to excess energy consumption, together with the contributions of the seminar's participants.

CIRCUTOR collaborates in the DIDSOLIT-PB project

CIRCUTOR is participating in the training of personnel responsible for the maintenance of the DIDSOLIT-PB international project. 23 attendees from 7 Mediterranean regions will take part in theoretical-practical training on the 22nd and 23rd of October

DIDSOLIT-PB project:
Development and implementation of decentralised solar energy on Innovative Technologies for public buildings in countries of the Mediterranean Basin

The DIDSOLIT-PB project brings together 7 partners from Spain, Greece, Egypt and Jordan and focuses on innovative technologies in the solar energy sector.

Through this public - private cooperative project, the aim is to promote and implement innovative technologies and transfer know-how in the field of small-scale solar energy systems, including that from the private sector and, especially, SMEs. The solar energy systems selected will be integrated in public buildings/premises through public procurement processes.

The image below shows the countries and buildings in which these new technologies will be implemented.
