Data is acquired using a DataQ DI-148U-SP A/D controller. Two of the three AC output phases of the turbine are connected to the DataQ, in most cases a step-down transformer has to be used as the DataQ has a limitation of a maximum of 10 volts. Typically a simple door bell step-down transformer (purchased at your local hardware store) which goes from 115v down to 15v (10:1) is sufficient. This gives us the ability to measure the turbines RPM and voltage output.
A shunt connected to the rectified DC can measure amps, and is connected to the analog input side of the DataQ. Now that we have volts and amps - watts can be calculated.
But what would a wind turbine installation be without measuring wind? Our software also has the capability of connecting to a 'bare' Davis anemometer - wow now you can monitor and log wind speed and direction!
All with a single software application!
Let's not forget about Auto-Shutdown... Manual shutdown/restart are provided via the PowerDashboard menu, in addition our FREE remote access Smart Client program (PDSmartClientPro) provides the ability to remotely shutdown or restart your turbine!
And of course you also have all the other frills that PowerDashboard supplies, except it will not show solar arrays, and it does not communicate with an inverter.
* Users that would like to have wind speed and wind direction information, requires a DataQ DI-148U-SP controller. This controller contains 2 string pots, 2 analog inputs, and 6 Digital I/O ports. Wiring the string pots to the Davis 6410 anemometer simplifies connections.
