wrong battery export readings

[cridemichel]

Describe the bug

Dear Developers,
I have a Solaredge inverter SE5000H with a DC coupled LGchem battery with a capacity of 9.6 Kwh and
a solaredge power meter. In energy dashboard I am using:

• a sensor template for solar production which is equal to (since "sensor.solaredge_i1_ac_energy" is the energy produce by the inverter and not just the one produced by solar panels):

{{ (states('sensor.solaredge_i1_ac_energy') | float) - (states('sensor.solaredge_i1_b1_energy_export') | float) + (states('sensor.solaredge_i1_b1_energy_import') | float) }}

• "Solaredge I1 B1 Energy Export" for energy exported by the battery
• "Solaredge I1 B1 Energy Import" for energy imported by the battery
• "Solaredge I1 M1 AC Energy Imported" for grid consumption
• "Solaredge I1 M1 AC Energy Exported" for energy returned to grid

The readings from battery, inverter and power meter are all reasonably correct except
the battery export (Solaredge I1 B1 Energy Export) as you can see from the follow screenshots,
taken from mysolardedge android app and home assistant energy dashboard.
Note that being battery export wrong, the solar production is consequently wrong (see formula
reported above). Note also the battery import is correct, i.e. equal to the value reported
by mysolardedge app and this asymmetry is rather strange, isn't it?

Firmware of solaredge inverter and LGchem batter are both up-to-date.

Expected behavior

I would expect values from energy dashboard to be equal to ones from solaredge android app

• I have read the Known Issues https://github.com/WillCodeForCats/solaredge-modbus-multi/wiki/Known-Issues
• This issue is not about a template error (do not report template errors, read https://github.com/WillCodeForCats/solaredge-modbus-multi/wiki/Template-Design-Notes)

Additional Context

No response

The integration doesn't make any calculations or change data, we are just passing through what the inverter gives us over the modbus connection.

Since I don't personally have batteries I can't answer battery questions, but maybe someone else can.
