Yep, same. I bumped up the PV start voltage and tada
Note: This was a problem before FAB-1717 for me
EG4 18kPV issues - turning on and off repeatedly at sunrise and sunset

Is your inverter connected to the grid? Or a battery?
If there is no Ac input or battery it is normal for the inverter to try to start and fail as the sun comes up. But it would be great if MPP could add an adjustable solar start voltage as well.

Good to know. I think it could/should be fixed on the firmware side.
I'm connected via battery.

So the lux 12k exposes the solar voltage startup setting to end users whereas the eg4 doesn't?

I am a dealer with my own code. So I have access to those settings. On the app. But anyone should be able to adjust it at the inverter. Under settings-advanced

OKAY so definitely an issue there. Is it the battery that clicks or the inverter?

It's adjustable on the 18kpv

We know its adjustable on the 18kpv, but is it adjustable by the end user? My understanding is that it is not!
Correct me if I am wrong.
Yes it is on the EG4 18Kpv, but can only be accessed on the unit by the end user.

It can be adjusted at the unit! , and by your distributor/installer!

And without a secret password?
It sounds like some hysteresis needs to be programmed into the controls. Like a time off timer so things dont change when pv power input is on the edge of the setting.
Is the inverter manual being updated as the firmware changes?
It sounds like this inverter has potential after the bugs are worked out. And they drop the price. Thanks to the test subjects that have had to endure the issues.

The default password on the display is just 0000 there has already been alot of bug fixes and luxpowertek seems to be quite responsive when it comes to recognizing and addressing bugs.
This inverter has great value when comparing it to the sol-ark 15k
Wich is comparable in specs
But yes a lower price is always welcome as long as the quality stays.

Please elaborate....
The Sol Ark 15K is now down to about $6500. The 18KPV is $5200
The Sol Ark does 15KW continuous, the 18KPV does 12KW continuous.
$ per KW of AC output they exactly the same.
It appears that the price of both units is dropping.
Personally I need more than one 10KW+ unit. The huge amount of pass through doesn't really make sense for me. I'm not trying to eliminate my main panel. I already have subpanels, three of them besides the main panel. For bigger houses I think this is pretty common.
