ADDITION: The 60W current clamp battery consumption remains constant even with the Gneerator port microinverter feature switched off. So the 84W can't possibly exist as a real power consumption.
UPDATE: After installing two new batteies today and leaving the microinverter option off for half the day, it's now magically fixed, now reading 0W!

What is a furphy in Australia?
A furphy is Australian slang for an erroneous or improbable story that is claimed to be factual. Furphies are supposedly heard from reputable sources, sometimes secondhand or thirdhand, and widely believed until discounted.

The idle consumption on the deye's are known to be ~60w - when on grid I believe it pulls that from the grid as it's more efficient to not have to do a step up from 48v to 240. So idle on grid is just a few W but from DC is 60w ish... As for the Gen port reading, who on earth knows. Maybe the unit only binds to grid and when the mode changes to micro/gen it feeds from the gen input...

2 x 42W is the answer! 😂
It's probably an error on Solar Assistant, maybe you should report it so they can fix it.

Probably a software bug, but maybe the inverter switches on an auxiliary small 240V AC supply (small inverter) internally and feeds it to the GEN port, in order to synchronize and enable the micro inverter on the roof (obviously the micro inverter needs to see a "grid" to enable itself). If your big invertes has some sort of "debug" menu on its screen, it is worthwhile to check if itself reports these 84W somewhere or it is a bug on the SA software.

@EEVblog2 Does the 84w show anywhere on the touch screen? This is a Solar Assistant problem as it showing graphs for an item that isn't configured. If in Microinverter mode you need to ignore the Generator/AUX data in SA. On my setup the Graphs for both Gen and Aux show 'No Data' in the middle which is correct. Do you have the latest SA version installed? EDIT: your opening screen show the Aux Load Power as 'No Data' which the Gen Power graph should also show. It's a piece of ghost data/bug which you should report to Solar Assistant support.

The fact it's a constant unchanging 84 W implies to me it has to be a data interpretation error, if it were a real self consumption reading I would expect it to fluctuate by at least a watt or two when stuff happens or the temperature changes etc.

I would guess it's an issue with Solar Assistant, maybe it's deallocating the memory for that generator power variable which then gets used for some thing else that just so happens to be '84' (idk what language it's written in, but it's possible), I would've expected it to say 'no data' like other graphs with generator disabled. Or it could be a serial message from the Deye changes format between modes and Solar Assistant isn't expecting that format so parses it wrong.

Have you tried changing it to micro-inverter mode and then rebooting the computer running solar assistant?

Go in to solar assistant go to settings drop down to battery the disconnect the advanced skip down to self consumption and you can change this figure to suite your self consumption

[dama]

It's a pre set on solar assistant you can change it

[Chris_Grossman]

84W should easily show up with a thermal camera or by touch if it is real.

Having the Gen port on MI does make the unit consume more power (around 20 watts) but this also varies between firmware versions.

[HomeGrownAlchemy]

With the circuit breakers /rcd / isolators, are they 2 pole (a +n) or are they just breaking the active? Possibly neutral to earth current flow? When you change the gen port from mi to gen, was there a click of a relay inside the inverter?

[erikdenhouter]

0:51, these switches, what a real bad design for a power switch. Both need a real bright colour on the lever arm, and on the ON-side a big dot in the same colour, and on the OFF side in black the text 'OFF'.

[filipbataz]

My gues is that this is software bug, but could be bad sensor some where. Doubt the latter but it is posible, considering instalers you had.

[stevebright]

Could it be that the Deye is treating the micro-inverter as a grid-tied inverter, so it presents a grid voltage to it?

[eimparas]

Definitely sounds like software, Data acquisition issuse.

How does solar assistant draw data from the deye? Does it have a api?

[tanteparodie]

Hello, does the manual for the SunSynk SYNK-5K-SG04LP1 provide more information than the manual for the Deye SUN-3/3.6/5/6K-SG04LP1?

[txbrent]

As a mechanical engineer I'd blame the software...

[kaz]

For it to be stuck at the same value without ever changing must be a firmware bug

[hillppari]

what i dont get why is the microinverter on the gen port when it can use it if its plugged to the grid normally.
