Yield increasing when charging battery from grid

[Joebinator]

Hi!

I was charging from the grid tonight, because of low electricity prices, and the sensor.inverter_daily_yield as also the sensor.inverter_total_yield were increasing.

Any ideas how to work around this? I have configured my sensors according to the wiki (https://github.com/wlcrs/huawei_solar/wiki/Daily-Solar-Yield)
