CDP-0: An essential element in any photovoltaic self-consumption installation

on .

Constant increases in energy prices are leading more and more people to want to install a self-generation system with solar photovoltaic energy in their house or business to reduce energy dependence and reduce their current energy-consumption costs.

In 2013 CIRCUTOR developed the concept of the Dynamic Power Controller, an element that ensures zero injection to the mains. This has allowed CIRCUTOR to position itself as a leading company in the marketing of self-consumption systems and solutions.

Today, the CDP-0 has become an essential element in any photovoltaic self-consumption installation. In line with its objective of constant improvement, CIRCUTOR has now brought the version 2 of the CDP-0 firmware to market, which includes new features such as:

  • Ability to manage the major inverter brands
  • Web monitoring (smartphone, tablet or PC)
  • Ability to manage several inverters in a single installation
  • Double protection against network injection
  • Ability to download the *.csv file with historical data on consumption and generation via the Web

The new version of the CDP-0 firmware is available free of charge and allows users to update their units to incorporate these new features. Units sold from now on will come with this new version by default.

These new features have made the CDP-0 a useful element for installations with small consumption (homes, second residences and service buildings) and large consumption (companies and medium-sized industries with the space available to install photovoltaic generation systems).

CIRCUTOR Heavy Duty Capacitor: Consolidated strength

on .

For twenty years CIRCUTOR has been using gas impregnation technology which, together with other advances, provides the capacitors with what are known in the market as HEAVY DUTY features.

The capacitors permanently support 1.8 times the rated current, reaching 2.5 times RC, and can reach an inrush current of up to 400 times RC.

Class D of the IEC-60831, the low voltage capacitor manufacturing standard, sets a maximum working value of 55ºC, but the strength of the CIRCUTOR Heavy Duty capacitor enables capacitors to work in extreme temperature conditions, occasionally supporting up to 65ºC, with this being another key feature in ensuring 150,000 h of useful life. All these features make CIRCUTOR Heavy Duty capacitors highly resistant and long lasting.

Manage and control the maximum demand with the new MDC series

on .

Due to the constant increase of the electricity price, all types of customers must find new formulas to reduce their electricity bill. To succeed in this, we are presenting our new power management system to control the maximum demand: MDC series (MDC 4 and MDC 20)

FNov MDC

The main objective of the new CIRCUTOR MDC series is to manage and control the maximum demand of an installation. To achieve this objective, the device connects and disconnects some loads (non-critical ones) to ensure that the maximum demand will never be higher than the contracted power, avoiding electricity bill surprises. Moreover, the extended MDC 20 range, allows a tariff control to adjust the loads for being connected on periods with lower price, avoiding high consumptions due to loads simultaneity during high tariff price periods.
