using the back of a car alternator to charge control my battery bank. This video shows how to connect up a car alternator to your 3 phase turbine so you can charge a 12v battery. We will use this with our table top turbine when we get to charging so don't worry, the table top turbine will be a very practical thing indeed to build. #scraptopower #offgrid #homemade #chargecontroller #fyp | Barra Mulligan

Here I am showing you how to use the back of a car alternator to charge control your battery bank. I am just using the back of the alternator because that's the only part we need. I use a low rpm river turbine to give it the 3 phase power. I am not using it at the moment because I run a hybrid hydro and solar charge controller for charging the workshop but I will definitely be using this on a remote site to give 240v where needed . Like share and follow for more interesting builds from already a

This is another video that got over 1 million plays. It shows the outside charging cabinet using the back of a car alternator to charge a battery from a washing machine motor mounted on a bicycle mounted on a air handling fan. I have the blades on the fan closed off to make buckets. I generate in 3 phase ac at 2 amps per phase. The voltage on the Ac side will be from 11.5 to 13v ac. The alternator part turns this to a charging DC voltage. All voltage readings depend on state of battery at the ti
