Filter wrong inverter response

[Lawei]

I have integrated my SUN2000 PV Inverter with this Plugin through Venus MQTT to my Home-Assistant's Energy Plugin.
This shows me hourly production. Unfortunately sometimes this value rises for the complete Energy-Counter-Value from one moment to the other (especially at night).
I think the SUN2000 Modbus (because huaweis impl is very pure and has several issues) sometimes answers with 0, so the difference to the next (correct) energy counter value is much to big.
This is a known problem for me, i also faced it on my SMA inverter (i wrote a plugin for it myself because of this and other instabilities).
A zero return for energy counter of the inverter should be ignored in any case!
