I are the reading on this ok? (1 Viewer)

Have a Smart Solar Controller fitted to our new van. Having very little info on the product I took the two photos about 10 minutes ago. Do they look ok to you? Bright sunny morning .

This is just idle speculation, while I work up the energy to go and get a coffee... you'll probably get a better answer.

The graph is way too noisy - why? It's showing 1V fluctuations over a timescale of maybe a second, which is way too fast to be explained by solar fluctuations. Does it have some way to enable filtering? Why would it even need filtering? This implies to me that the electronics isn't quite set up correctly.

You're getting 63W (why does it show 62?) at the input, which is probably pretty good. What's the panel rating? This is being down-converted at 95% efficiency, which is good (too good, maybe?)

Overall, looks Ok-ish.

Is the noisy graph an indication of a Multi Power Point Tracker solar controller doing its job as it hunts for the best load to pull from the solar panel. Probably completely normal.

I find that if I wipe down the solar panel with a damp cloth the solar input trebels!

Solar panels need cleaning at least weekly (or every time you get the van out of storage)
