Herein lies a can of worms:
Solar Yield should actually be in Wh. (or kWh for larger systems)
What this tile actually displays is “Solar Power” (Current value) This is in W or kW.
So either the Title for the reading should be changed, or the value displayed should be changed. Or the yield should be added to the tile.
What you really need to look at is what the battery is doing, this gives you your value in Amps. But you still need to calculate from the capacity in Ah, how long you have to charge / discharge…
Your data units setting in amps is correctly reflected in the DC loads tile. It could be an oversight that this does not also change the solar tile.
