My first guess would be those two data points were gathered at slightly different times on a partly cloudy day. Do you find its consistently inconsistent?

The app is being worked on at the moment. They are trying to fix several things. This is probably affecting the readings you get
I may have missed some posts above, I apologize. But have you verified you have the latest firmware on your wifi dongle? I posted earlier in this thread that there is more data available with the newer firmware, but I'm not sure if it would affect the accuracy of those numbers. I do know that the polling is slow, and it could be a result of the slow polling in changing shade conditions. I just checked my inverter (sun is low here) and those numbers are off by a few KW, but not as far as yours.Just to confirm... Those 2 readings should match up then? (Total of PV's 1-4 and "Total DC Input Power")
I never thought about the fw on the dongle... How do you check it and how to update it? Not sure I have any instructions/info aside from the lines page or two in the EG4 manualI may have missed some posts above, I apologize.

Anyone willing to clarify what's I see via the monitoring app as to why realtime graphic shows 540w of solar production ... But the device statistics at the same time shows 1110w of combined PV input?
Why the difference? Where the rest going?

Do you have enough load? Or enough MPPT capacity?
MPPT controllers will only draw from PV based on available load. If there is only 2700 W of load (battery charge capacity + loads) then that's all the system will generate.
I've only had mine for a couple of months, but I share your concern about the fans being on whenever the inverter is active. I've been putting the inverter in standby most nights by switching the battery comms to a port that's not connected. The primary reason for doing this is to reduce idle load and the lack of fan noise is a nice bonus.Hey guys
Is it normal for the inverter fan to always be on? I'm concerned about the durability of those fans.
Not always are in high speed but always on.
Is anyone cleaning the fan in a frequency basis?
Update on the inaccurate PV current readings: I started recording some data and put together this graph showing the discrepancy between what the inverter reported and what I measured.Also, something annoying that I've noticed is that the reported PV output is usually too high. I noticed this when I first hooked up PV with no loads behind it--the power output measured with an Emporia Vue CT and a clamp meter was 200-400w lower than what the MR showed. The discrepancy was the worst at lower current values.
Hi there,With no grid, just battery and PV connected, when sun is not sufficient to power the inverter, the relays click and the screen turns off. The screen will then turn back on, show 'initializing' and seem operational. Then if I see PV get to roughly 300watts, the relays will click, the screen will turn off, say initializing, etc. Its almost like the inverter is switching its power source between battery/pv or something. Not sure. Perhaps I have some settings wrong.
I am running in self-consume, but I am unsure what DISC-POWER means, perhaps that is something to do with it? PV-POWER is set to 100%
