Welcome! In 2012, my wife and I built our own super-insulated home. The house is one and a half stories, which includes two lofts. To some, it would be considered small, but it's perfect for us, and is even larger than most apartments we have lived in. The house is so well insulated that we don't even need to run a heater, save for a couple months out of the year. Join us to see how we built it and what projects we continue to do!

As our channel and website (www.davidpoz.com) grow we will put out more energy and efficiency related videos. We are constantly meeting like-minded people along the way who have their own twist on energy efficiency, which is awesome; the online community is great. We have even done an interview with another energy conscious homeowner and hope to do more in the future.

Thanks for stopping by!

    OK, gotcha. This module would have originally been built to be part of some large system. For example, I've seen shipping containers with hundreds of these modules. The shipping container might have one central computer collecting data on all the individual modules. The system as a whole is a BMS, but the individual circuit board is the BMU. I replaced that with a stand-alone BMS.

    I was considering buying the Growatt 3500 Watts inverter/MPPT charge controller at 48V, but after talking to an installer who has experience with Growatt I changed my mind. He said that the inverter will shut down if the battery voltage drops below a certain threshold, but the MPPT will also shut off so the unit does not charge the batteries. He recommended that I get a separate MPPT charge controller and stay away from the All-in -one unit like the Growatt. Just saying.

    It's a great point. Having separate CC and inverters gives you more flexibility. Personally, I set my low Voltage cutoff fairly high (48V) and never had an issue. I ran my house Growatts for over a year. However, now I'm running on Schneider equipment.

    Your are correct that an alternator is not the most efficient thing out there. I did this because alternators are easy to get used and cheap, and I always wanted to try one.

    David, I loved your project. By any standard it is a success. Reading the comments obviously you can optimise it in many ways, however, what strikes me as your project's greatest strength is that it is all a made from available parts. Arguably you could repair/keep this thing going in a zombie apocolypse! Anyone can go and spend $3k++ on something sophisticated, but can they repair and keep it going if their life depended on it. As a pragmatic engineer I say, if that was your goal then you 'hit the nail right on the head'. Keep up the good work.

Go to the insight home location. 4. connect to the insight home's wifi signal 5. Open the insight home using an internet browsing software (ie. Crome) 6.
