LH Calculator

Welcome to the PowerSpout Advanced LH (Low Head) Series calculator.

This is a powerful tool which will automatically update as you input information. Just like any program, it is only as good as the information you enter, so please take time to read the system design and calculator manual.

After entering a value, do not press Enter. Simply wait 2 seconds for the calculations to update after each change.

Preferences

Update any calculated value that is in an entry box with your preferred value and the calculator will work out the other data as a result of your changes. Experiment with every possible setting and see how it affects the power at your Shed.

Electrical

Standard design voltages are 80, 100, 200 or 300 V. These inputs will determine what cable size is necessary to connect your PowerSpouts. If you have available cable you can override the suggestions and lock them. If you need to interpret metric measurements into AWG Gauge, you can read the Next Size Up Cable value.

Save & Share Results

If you wish to save your results above and share them with a dealer, please input your own email address, and select a dealer if desired. You will receive an email containing a summary of the results and a reference number. The Job Reference is an optional reference that you can use to track results. It only appears in the email that is sent out, and can't be used to search results on PowerSpout.com.

Job Reference

Your turbine will be designed for the site data you supply above. If you operate it on a different site, the output power will differ. A new generator core may be required to obtain the best results in such cases. If you intend to run your turbine over a wide range of flow rates, you need to state this at the time of ordering. A different generator core can be supplied for an additional charge.
