Monthly data not matching for usage

Hard to see anything amiss from here though the differences between Total Usage - Solar Production and From Grid - To Grid are off by one another by about 1kWh - those differences should be spot on to within 0.1.

My solar production is within 0.2kWh accurate, which should be considered a rounding error.

But if you are seeing negative Total Usage during the day, that’s not good unless you have an appliance inside the house that’s generating energy.

Correct, as my thread here describes:

How to hookup a hybrid inverter?

Danny, did you ever get an answer to your question? I have a hybrid inverter feeding my main panel. It can be either a producer or a consumer. I have several loads sitting off of a critical loads panel behind the inverter. I have my solar clamps on the main panel where the inverter ties in but sense is showing all my critical loads usage as solar generation. Anyone know any way around this?

Sounds like you have an energy source (the hybrid inverter) that Sense isn’t seeing through the solar CT. Or if the hybrid inverter has a battery, Sense might be seeing the energy when it is produced rather than when it flows into main breaker panel ?

Basically I keep the batteries charged during the day with solar.
The unit is able to put energy back into the grid (sell mode) if the batteries are full and enough sun.
My MPPT charge controller tells me it is producing about 5kWh per day that in puts in “the batteries” but part of that is used to offset the load on the output and when there is more solar available going back in to the grid , but on the CT’s of usage of the sense.

Coming back to my original question:
Sense does not show negative values on the daily usage graph. When you mouse over you can actually see if shows eg -200 watt. Could it be that that energy, although not showing up in daily operations, does get calculated for the monthly totals , hence my missing 51.6 kWh?
