Using the "Select Parameter" button, select (tick) the following boxes:

  • DC Power PV1
  • DC Power PV2 (if you are using the second MPPT)
  • AC Power R/U/A
  • Grid Frequency
  • Total Grid Power
  • Total Consumption power
  • Battery Power
  • SoC

Then post your graph.

OK, so I was on a different SolarMan site ?? https://home.solarman.cn/main.html

So this is the best I can do (no SoC)

Can you also post pics of your setup screens?

Was this a cloudy day, or are your panels shaded in any way?

Please also post the same graph timeline with (V) DC Voltage PV1, (V) DC Voltage PV2, (A)DC Current 1, (A)DC Current 2, AC Power Total Power (Active) and (W)Battery Power.

PV voltages look very healthy. and PV was able to supply the spike of 5K at around 13H00 

The only time I see it pulling from grid is a tiny blip at 11H00, and then just before and after 15H00. Were there clouds at those times?

Nothing... perfectly clear day...

I'm just worried that, because this happens almost daily, that it's a sign of a "bigger" issue

Found the SoC selector... as you can see... the battery is fully charged... so I need to know why it's pulling from the grid, and not the battery!

Please add (W) AC Output Total Power (Active) to the graph above?

Interesting that you are limiting battery charge to 40A in the inverter's battery setuo , yet the battery is happy to accept 200A charge (from the LiBMS screen). Also from the LiBMS screen, the batteries are happy to accept a 300A discharge, yet you have them setup as 200Ah?

What batteries do you have?

I've got the FreedomWon Lite 10/8, but yes, I see they can charge and discharge at 200A...

Bumping it up to 100A should not hurt it, that's 0.5C

I see that max continuous discharge is 240A, 300A is max every 5m per 30m cycle.

Need the system flow chart and the info screen. Seems that you are exporting to grid a bit.

Need the info screen that looks like this

Need to check if the CT value is negative, then it's installed incorrectly.
