I am happy to announce the availability of the latest video in the established electricity production systems series. I have now connected the MPPT Solar charge controller to a battery bank and can test the performance of the Rotoverter together with the overall power distribution capability of the charge controller. Our initial test with a single-phase motor and a car alternator was rather disappointing below 20% efficiency. Looking at the unbalanced power motor types of primer to electric generator my hopes are dimmed. Maybe there is a surprise! You find the video under movies/established-electricity-producing-systems/ at the bottom. Non Members and Basic Members can purchase the video.
