Greetings, I need some help wrapping my head around the "interface" for the EG4 6000XP unit.

In the simplest form I want it to work as follows.

1: Solar should be used to power the loads as priority
2: Pulls remainder of power from Grid when solar cant keep up.
3: Does not charge the batteries, they are shared with the Victron MPII and it does the charging of the batteries.
4: Pull from solar/batteries in the event of a power failure.

Sounds simple, but I can figure out the right combinations of settings in the Maintenance section to make it perform in this manner.

Any help would be greatly appreciated, oh yeah and EG4-Luxpower, a clearly written guide would be helpful, or even some short how to videos.
 
Here are screen shots of the way it is now, it feeds back into my Victron system through the DC side instead of charging the "fully charged" battery bank, the Victron uses the additional DC input to power the loads on the Victron side.

Given that this inverter lacks a battery backup mode, the desired setup may be challenging. Nonetheless, it might be possible by adjusting the on-grid discharge to 90%, which is its maximum limit, or by setting the voltage according to the battery's bulk charge specifications on this setting. Subsequently, you would need to schedule the periods during which you prefer the utility to power loads using the AC First option. As for not charging batteries with the 6000XP while having batteries connected, I do not believe this is possible. Included below you can find a logic chart for the 6000XP.

Why don't you want excess PV from the 6000XP to charge the battery bank? It's just another charger. Seems like you would want to utilize all solar potential to keep your batteries charged wouldn't you? This is how I have mine all set up (edit: well, I don't want the 6000 to only use grid, I want it to use whatever power is available before grid).
 
The not charging batteries wish is not a must, right now it feeds the charging power back into my Victron system and uses the solar this way, I have the victron set to keep the batteries fully charged.

You mention the EG4 6000 does not have a UPS mode, however it does switch to battery when the grid goes down, I have tested this many times.

The one problem with the chart you listed is it is not clear how to enter these settings into the multitude of settings on the Maintenance page, most of the reference material I see calls the setting one thing on the pdf file and another thing on the EG4 Maintenance screen, making it extremely hard to figure out the correct programming, I guess I will leave it set the way it is for now and simply let it feed into the Victron system.

If anyone else has a solution to my issue, please let me know, Thanks

Right now the EG4 sends the Solar to the battery bank, which is fully charged so the batteries don't use it, instead I have the Victron setup for a DC Power load, this sends the excess solar from the EG4 to the Victron loads, why it is not sending this to the loads on the EG4 side is what is baffeling me. In this screenshot it shows the EG4 in Solar/Grid mode, which means to me it powers from Solar then Grid to supplement?

So the EG4 isn't using the solar to power the loads at all?
 
Try turning off "shared battery". It looks to be grouped with the "parallel inverter" settings and I'm not exactly what that setting does, but you don't have multiple 6000XP inverters paralleled together. I have this setting disabled as well.
 
Same thing, no change, I have tried changing this setting before, but left it on since last time it had no noticeable effect.
 
Nevermind. It looks like you're in "bypass mode" and according to the chart @EG4_Jared shared, Solar charges the battery while grid powers the load.

It seems like even if you set a time for AC First, Grid will always take the load while PV charges the batteries. It seems like you have to be in some kind of inverter mode for PV to go to the loads first.

I have set it for A/C first from 0:00 to 23:59 so it forces it to pull from the grid, if I flip that to 0:00 and 0:00 and flip the switch I get the following. See the screenshots, this makes it draw from the shared battery-dc power bank on the Victron which makes the Victron draw a load from the grid to compensate for the draw from the EG4, so using the A/C first settings have at least allowed me to route the solar to the battery-dc power loads without wasting it.

Hmm, yeah it seems like the 6000XP isn't designed for how you're trying to use it. Any time it looks like it's in grid/bypass mode, PV goes to the battery.

What about setting the "On Grid EOD Voltage" to a higher value so it only uses the top 10% or so of your battery for the load. PV will power the load first and extra power will come from the battery till it reaches that EOD Voltage. Once that voltage is hit, the system switches to bypass mode allowing the grid to power the loads and PV to recharge the batteries. Once Battery is 3V higher than the EOD Voltage level, it will switch back, rinse and repeat.

I am going to give this a try and let you know if it works out, or if I have an issue wrapping my head around it, if you don't mind :)
 
I set my Ac fist start at 17:00 and my AC first end at 08:00 hrs
Set my Discharge settings to control by voltage and the on grid EOD to 53.6v

While I like the idea of this unit powering my 240v Mini Splits, I have to say I am frustrated by the software on this unit, even compared to the Growatt I own, that software is not much better, however I could set the loads priority using one of 3-4 modes available, this is not an option on the 6000XP, but that is one of the issue you face when buying these AIO units, you don't know if it will work for you situation until you have it in your hands.
