  • ILNDNEV

    Meet “Island NEV,” our Neighborhood Electric Vehicle. It’s small and super convenient, and with a top speed of 25 MPH, you can think of it as a street-legal, pickup truck-shaped golf cart! It’s great for the vast majority of our trips, whether it’s taking the kids to school, grabbing groceries, picking up supplies at the…

  • Setting up a VPN for Home/Intranet Access with WireGuard

    If you’d like to securely make services in your home network available for yourself — and only yourself (and others you trust) — from outside, using WireGuard, this is the post for you! We’ll be setting up VPN Server on Linux for point-to-site access. Prerequisites Also, just to be sure it’s clear: What you should…

  • My Experience with Emporia’s Vue Home Energy Monitor

    About my Setup My Home I have solar panels and a battery that feed into a Load Center (LC). Most of my home’s loads/circuits are wired to the “House Panel” (a sub off of the LC) while a few others are wired into each of the Load Center, the Garage Panel, and the Main Panel…

  • AI-augmented “Reading” — Many-to-One

    In Reader-augmented Writing, I present a way to think about how communication has evolved; how written language, the printing press, and digital media have allowed more people to reach more people with ideas (one-to-many), with readers adding to what authors wrote (many-to-many). Now, with the recent significant developments of large language models (LLMs), I’m adding…

  • Our Heat Pump Water Heater – Part II: Our Experience with It

    Installation & Initial Heating Choosing a plug-in, shared-circuit model made installation relatively straight-forward for me as I didn’t have to get any electrical work done first (no need for a new dedicated outlet nor hard-wire junction box). I just plugged it into the same outlet as my clothes washer and dryer, which hasn’t been a…

  • Our Heat Pump Water Heater – Part I: Choosing a Water Heater

    Essential Concepts Crash Course Heat Pump Resistive heating: A lot of heating with electricity works by just using wires that heat up when electricity is run through them. This is called resistive heating, and some common appliances that work this way include space heaters, hair dryers, stoves with coils, and many older water heaters. This…

  • More than one (or larger) electrical energy storage battery?

    There are various reasons to want a second battery, and a second battery is less helpful to some of those reasons than others, so there’s no simple answer. But if I had to make a general recommendation, it would be to get a second one because it’s an important factor in going all electric; that…

  • A look at the production and finances of my Tesla Energy system

    There are so many factors that affect how a solar energy system will perform and behave, including latitude and longitude, house construction, house orientation, roof shape, trees, neighboring buildings, nearby mountains, HOA, utility rates and regulations, family size and habits, whether you drive an electric car and how much you intend to charge at home,…

  • FAQs about Tesla Energy systems

    Terminology Here’s a quick reference of concepts/terms covered in earlier posts that are important to answering some questions: Term Quick Definition My Setup Backup Load; “inside”; critical The load that remains connected to solar and battery when the system is disconnected from the grid. Everything but my garage (where the car charges). Monitored non-backup load;…

  • Understanding my Tesla Energy System

    Major Components Load Center This is where everything comes together: PV, Battery, Home, and Grid (via the Tesla Gateway). Using the pneumatic system analogy (of the previous post), this is simply a chamber where everything is connected so air moves freely and pressure is equal throughout the system.
