It is a fun little hobby project. I enjoyed building it, although it's quite simple.
I must say that the load on the battery is not equal exactly to the actual load because the solar charge controller doesn't seem as precise in its measurements unfortunately.
- louwrentius 6y agoIt seems that HN is now hitting my Pi 'hard' but it doesn't even register on the CPU (5% across cores). I do notice a small increase in power usage. I wish I had implemented a mechanism to share my Grafana dashboard tracking my solar metrics. (sorry)
- vvanders 6y agoIt's a neat project, we added solar based watering to our greenhouse and having grafana as a dashboard was super handy. Renogy's Rover MMPT chargers speak modbus over rs232 so you can interface it directly with a PLC or other industrial automation tools. The whole thing is self sufficient and was a real blast to put together.
- louwrentius 6y agoThat sounds awesome! Do you have a writeup about that somewhere? Would be nice to share! I love self-sustaining solutions.
- vvanders 6y agoNot yet although I've been considering it. There's a lot of things that are really handy but not easily searchable(like din rails, they're the lego blocks of industrial automation) which I think would be neat to aggregate in one space.
- louwrentius 6y agoPlease come back in about 8 to 10 hours when the sun comes up to see what I did with the icon (currently a battery).
