We have replaced the older model green case hydro turbine with the all new PowerSpout. www.powerspout.com

Please note the new PowerSpout can connect to MPPT regulators and grid tied inverters, so is a better option for many clients.

We sometimes get in 2nd hand units as customers upgrade to the new PowerSpout turbine.

We have 0 new unit left in stock at this price.

We have 2 x dual jet 2nd hand units due soon, clients upgraded to the new PowerSpout, but they do not hang around for long.

All old stock green case turbines are sold.
