Solar

The usual way to manage critical loads is to isolate them in a subpanel so that during an outage or other similar event you can power just that panel. That works more or less OK when you’re doing new construction, or you can easily access the wiring coming into your main panel. But if your […]

My experimental solar container is doing exactly what I intended it to do: Teach me how modern solar power systems work. I’m definitely drinking from a firehose, but there are some things that make me stop dead in my tracks that just don’t seem to make sense. RSD (Rapid Shutown Devices) and the requirements of

“Nearly anything is really interesting if you go into it deeply enough.”—Richard Feynman Historically residential solar installations were frequently sold as AC-coupled systems (microinverters or string inverters), using the grid like a storage device to yield a return on investment by reducing the amount of electricity you buy from the grid. While that is a

Introduction to the Solar Container Videos This is the first video in the solar container series Which I shot at the early stages of planning. As the project progressed my plans changed substantially. The overall goal is to build a high-capacity three phase system to power my shop completely. I intend to remain grid-connected but

As the Expert Amateur name suggests, I’m not a professional electrician, which means no one pays me to do this stuff, but I’ve been working on electrical and electronics projects for a ridiculously long time, and I insist on studying and digging deep enough to know what I’m doing (hence, the Expert part of the

The neverending Solar Glossary I’m starting a glossary of solar electrical terms that I will continuously add to as long as new terms that seem worth defining pop up. It may seem that the terms used are just to confuse you, but really, any technical endeavor acquires jargon so that professionals can understand exactly what

Something for Everybody We are doing a solar project that will scale in stages to show how to do modern solar power projects from a simple cabin or small house off-grid, to a light industrial or commercial 3 phase system with all the stages in between. The intention is to demonstrate how versatile hybrid inverter
