Just over a year ago there was a blog about Hydro Power<\/a>, in which Markus Pauritsch used a Victron\u00a0 MPPT<\/a> solar charge controller loaded and driven by a Pelton wheel<\/a> water turbine to charge his off-grid cabin battery system in the Austrian Alps.<\/p>\n

As you may also recall a few weeks ago we left the subsequent blog: DIY ingenuity: Hydro Power MkII \u2013 Part I<\/a> at the point where the rebuilt system (after a storm) and his neighbour Werner’s brand new (joint venture) system were at the testing stage. But how did that go, did it all work?<\/p>\n

<\/p>\n

Just before we get into that – Markus’s off-grid cabin and Werner\u2019s nearby new off-grid static mobile home with its power system shed are shown above. Not only do both systems use Victron Energy products but I also discovered Werner has gone ‘Victron Everywhere’, equipping his micro off-grid trailer too!<\/p>\n

Hydro Testing<\/h3>\n

Here’s what Markus & Werner had to say about this phase of the project:<\/p>\n

“The first pressure tests turned out to be not so successful. The pressure went up to 7 Bar, but we had to make several attempts to keep the hose stable and tight. We connected the hose from the supply-pond with a pipe consisting of segments and we used ‘special’ foam to stick them together.<\/p>\n

\"\"<\/a><\/p>\n

Lessons were learned. Don\u2019t use foam for that! Not only because it doesn\u2019t last, but it can get into the main hose and getting it out was difficult to say the least. Plan B and we used a reduction and connected the segments with clamps. After everything was tight we had a stable pressure of 8 Bar.<\/p>\n\n\n
