I believe the Ecco is smaller due to colder climates not needing as big a heat-sink, hence why they're not sold here.

Look at using a Pump as a turbine (PAT). Power control is done by speed control using a VFD. Less efficient than a Turbine, but much cheaper. KSB have some good literature for spec'ing a pump for the specified head and flow of your application. Else contact JOAT, and ask for Neville.

Thanks Keith, I appreciate the heads up

Hi Coen, Did Revov ever resolve this issue. I'm very interested in their second life batteries, but won't take the plunge if they don't provide good back up. Thanks.
