solaredge_i1_ac_power is negative, but why?

[tschweitzer]

Hi folks,

having a question regarding the values that I see from my solar edge integration. I am having a SE10K-RWB48BFN4 converter with meter and battery. The converter shows its energy flow (solar generation or battery discharge) via solaredge_i1_ac_power. The meter shows its energy flow via solaredge_i1_m1_ac_power. I am calculating the consumption of my house as max(solaredge_i1_ac_power - solaredge_i1_m1_ac_power, 0).

Recently I saw solaredge_i1_ac_power being negative (while battery at zero) and my house consumption being lower than the power pulled from grid (solaredge_i1_m1_ac_power) by exactly this negative value. Why was that value negative? Was this charging the battery to some minimum because it was at zero? Then however solaredge_i1_b1_dc_power did not show a value.

See attached picture.

Any ideas welcome.
