Welcome to the Continental Control Systems’ support pages. This section contains articles to assist with installing, configuring, troubleshooting, and using our WattNode meter and current transformer products. Information on other products, accessories, and services that are sold by other companies that work with WattNode products are also list here.

Basic kWh energy meter available with custom output options:

kWh Transducer / Submeter
Multi-Color Diagnostic LEDs
Bidirectional Outputs
Perfect for Net Metering

The WattNode Pulse is a true RMS AC watt-hour transducer with pulse output (solid state relay closure) proportional to kWh consumed. The WattNode provides accurate measurement at low cost to meet your needs for sub-metering, net-metering, energy management, and performance contracting applications. The complete Pulse Output family measures 1, 2, or 3 phases in 2, 3, or 4 wire configurations. With voltage ratings from 120 to 600 Vac and current transformer (CT) ratings from 5 to 6000 amps, there is a WattNode model that meets your AC power measurement requirements.

Diagnostic LEDs

Three diagnostic LEDs, one per-phase indicates positive power (green flashing) and negative power (red flashing) to help troubleshoot connection problems, like reversed CTs, no line voltage, or excessive line voltage. See the manual for a full description.

Advanced Output Capabilities are available as factory options:

  • Standard output provides pulses on one terminal for positive energy and on another terminal for negative energy. This is useful with solar panels, where energy taken from the grid and energy fed to the grid can be metered separately with one meter (net metering).

Key Features and Benefits

  • Bidirectional metering: Net metering for PV (photovoltaic) solar and wind power generation with only one meter
  • Nominal 0.5% accuracy (see manual for details)
  • Small size for easy installation in junction boxes and electrical panels, see a sample installation diagram
  • Line powered: No external supply required
  • Detachable terminal blocks: Easy to install and remove
  • Uses Safe CT’s (current transformers), that output 333 mVac at rated current
    • Split-core CTs for quick installation
    • Solid-core CTs cost less and prevent tampering
    • Rogowski coils and Bus Bar CTs available for high current
  • UL, cUL Listed: Approved for use throughout North America
  • CE Mark: Can be installed throughout the EU
  • Assembled in USA, qualified under the Buy American provision in the American Recovery and Reinvestment Act of 2009 (ARRA)
  • Five year warranty
  • Pulse outputs: Compatible with most energy management systems and data loggers.

Safety Note

Warning: Hazardous Voltages – Only qualified personnel or licensed electricians should install the WattNode meter and current transformers.
