The CWC Datalogging System

This system collects, stores and presents information about the performance of renewable energy systems. It is intended to be flexible, low cost (installed cost under $500) and easy to install.

To monitor something you need:

• A CWC Datalogger (no PC)

• Some stuff to monitor (any of):
  • A kWh meter (or other transducers) with "pulse" output
  • SMA inverters
  • Fronius Inverters
  • Outback FX/MX Inverters and Charge Controllers, with "Mate"
  • Xantrex GT Inverter
  • A Davis weather station
  • A bunch of temperature transducers and a flowmeter on a solar hot water system.
  • transducers that use the Dallas Semiconductor 1-wire standard.
  • temperature, humidity, wind, event counters
  • A silicon pyranometer, 250 mV max.
• An Ethernet connection or dialup ISP
  • Uses ONLY http port 80 operations - no open port necessary

We provide a variety of web-based utilities for viewing your data on any PC, anywhere in the world.
