Mate3 and Wind turbines

Post by sb10701 » Wed Nov 06, 2019 3:42 pm

We are the Science Barge people in Yonkers, NY. Off the grid teaching facility w two greenhouses, outdoor classrooms and wind and solar renewable energy systems. We are wondering how to integrate our 2kW of Primus wind turbines into the Mate3.

I assume you are using other Outback equipment other than the Mate3? If you include details of charge controllers, inverters, battery monitor, etc., it will help in answering your questions.

The wind turbine is DC? Does it have a charger compatible with the system battery?

Hi,

If you are using the FNDC, along with its ability to read from 3 shunts, as long as the wind turbines can provide DC, and, more importantly, they can be stopped when the batteries reach full charge (some wind turbines have this built in, some you need an external control box with dump load), you can use the third shunt to incorporate wind into your system (e.g. 1st shunt = inverters, 2nd shunt = solar charge controllers, 3rd shunt = wind).

Be very careful about over charging your batteries.

A couple of wind turbines I use for example (https://www.zephyreco.co.jp/en/products ... ro_pro.jsp - in built programable battery charger, or this very very good copy of the wind dolphin https://www.bimblesolar.com/nemowind2000w).

One last tip, if you can get spare brushes/sliprings for your turbines, do so. These wear out and need replacing. There are some excellent all-in-one 3rd party replacements, something like this https://www.youtube.com/watch?v=g34GWHdApxE is good, something like this http://www.mercotac.com/html/sixconductor.html is very very good, but very expensive (expensive because they are fit and forget). Make sure to use a slip ring that can handle the high currents (use multiple slipring poles for one conductor for example).

Keep your DC wires as short as possible, and dont skimp on DC cable diameter/rating.

Wind keeps my batteries topped up at night, rather than running my system on its own.

Hope this helps.


Dan
