Electrical measurement: At Intersolar North America, Continental Control Systems will highlight its line of revenue-grade electric power meters, the WattNode® Revenue, along with its revenue-grade, split-core current transformers. The WattNode Revenue meters are fully tested and compliant to ANSI C12.1, and considered to be the most economical revenue-grade meters on the market. The WattNode Modbus has been certified to ANSI C12.1 accuracy by MET Labs, a nationally recognized testing laboratory, and listed as PBI eligible by Go Solar California. Because of their price point and compact design, WattNode Revenue meters are an ideal OEM design-in for PV production monitoring.

WattNode Revenue meters are designed for use in any application requiring revenue-grade accuracy and revenue-grade requirements, which are usually required by each state. The meters meet the accuracy requirements of ANSI C12.1 and support the Modbus®, BACnet®, or LonTalk® communications protocol or a pulse output. These compact and cost-effective energy and power meters complement the company's line of high-accuracy, revenue-grade current transformers (CTs). WattNode Revenue meters are designed for 120/208/240 Vac or 277/480 Vac applications and are UL- and CE-marked. Each meter is calibrated using NIST-traceable equipment following the procedures specified by the ANSI C12.1 metering standard, and each is supplied with a certificate of calibration. In addition to revenue-grade, bidirectional energy (kWh) metering, the networkable WattNode Revenue meters provide dozens of additional measurements: bidirectional power, demand, peak demand, reactive power, voltage, current, power factor, and line frequency.

The standard line of WattNode energy meters provides line-powered single- and three-phase, wye, or delta configurations of up to 600 Vac, for load measurements up to 6000 amps. The WattNode BACnet meter has been tested and listed by the BACnet Testing Laboratory (BTL) and supports full self-discovery of the meter and all of its objects, offering more than 50 electric power-related measurements, 64 addresses, and selectable baud rates of up to 76.8K. 

The WattNode Pulse Option PV, another member of the standard line, offers an innovative way to receive three independent pulse outputs from a single meter, thus measuring energy from the grid, (energy consumed), energy from the inverter (energy produced), and the bidirectional energy being returned to the grid (net energy).
