- In this episode, we get into the nitty gritty of monitoring the power generation, storage and usage with my solar controller.
I also give a somewhat in-depth discussion about how to accurately measure currents by using a shunt, possibly will send some people to sleep, but hopefully useful to at least someone.
This is episode 3 in a series about me developing my own home solar control and monitoring system.
As I discuss in this video, here is a link to a related videos by Robert's Smorgasbord.

Great video thanks and very useful, I live on a boat so use a shunt to measure all my current flow including from Solar of course. Going to dig out my old Victron 500A shunt now and have a play around with it. I have been caught out a few times with dodgy chinese chips, I had some AS5600 chips where i spent two weeks trying to get them to work, then idiotically bought some more cheap ones and stupidly used the supplied "diametrically opposed' magnets and spent a further two weeks wondering why they just wouldnt work only to find out the magets were in fact not diametrically opposed.. Live and learn I guess. Thanks for the videos, very interesting
Glad you found it useful, likely will be one of the few, but a few is better than none! As for buying chips from Ali-Express, I now find myself sticking to a handful of big sellers, never seem to get bodgy stuff from those stores. I know where I was going wrong though now, and now, if I find myself only finding such specialized IC on smaller stores, then this is a big red flag. Simply put, if the big stores don’t have it, then generally this indicates that such chips are not generally distributed in China, and likely what the small stores hold will be junk, so going to the international sellers is the better way to go. Small stores sometimes are ok for some very basic electronic component stuff, resistors, capacitor or mosfets and Chinese brand chips, but otherwise I steer clear. Thanks for mentioning the AS5600 chip, I was not aware of that particular type of IC, but I will keep it in mind in case I need such a chip for my project! What in particular did you use it for?
@@ForOurGood yes all good advice thank you. I used the A5600 for a combined anemometer and wind direction head on my weather station The 5600 measures the rotational position of the wind vane so wind direction and I used a ss441r hall sensor to measure the rotational speed of the anemometer using two normal magnets for balance. Took a bit of work figuring out how to mount everything. All parts 3D printed of course 😁 i did have an old sensor from a steering angle sensor from a car but it was difficult to interface with whereas the 5600 has I2C onboard and can output analog / pwm plus it can register down to less than 0.1 degree change. Seen people using them for intelligent rotary knobs and the like. I only use the basics as I am a newbie but it seems like a very versatile little chip as long as you get the correct magnets!
@@AndyJenkins999 Very cool project, and I like the way you implemented it. I have always planned to do a weather station, so I might steal a couple of those ideas! Thanks for sharing 🙏
@@ForOurGood No worries I was inspired by someone else on the Internet so it all goes around. 👍
