Right now, Cerbo shows pv production jumping between 0 and -5.3 W. I guess that negative value means there is some wrong formula in the sw that should be fixed.
I get the negative value both in Node-red
node "Venus system | MPPTs - power (W)" and MQTT at
N/<id>/system/0/Dc/Pv/Power
Venus OS version is v3.00~42
MQTT history log:

{"value": 0.0}
Note: During the day, when there was enough sun, values were correct - matching expectation. On the other hand, I can spot 0 jumping to -5 easily, but would not notice 5 W jumps on high values.
