Suggestion 12000XP and Generator Switching

Thanks @joel-brodeur and @pawnee.   I don't understand how an off-grid inverter can be so bad at gen switching functions but it's almost unusable in its current functionality. It's probably my ignorance but I also don't understand how a fix is taking so long, seems like a couple tweaks of the firmware would fix this, I'm getting down about it... 

This is my first inverter experience, has either of you used an inverter with proper gen switching? I'm not opposed to switching to another maker at this point. 

@wardo5757 My old system did handle gen switching much better.  However, it was a conglomeration of vendors.  My inverter was a Magnasine which I did not feel comfortable with going to lithium.  My MPPT was Midnite Classic, which worked great but again not certain about lithium.  I also had a battery management system and a remote-control board all by Magnum.  I liked the system other than none of the volt reading or SOC matched between hardly anything and remote monitoring would have been overly difficult with Starlink and CGNAT.  I updated my system based on power needs being met by indoor lithium storage and remote connectivity and control.  EG4 was able to provide that.

I agree that the gen start/stop functionality needs some work, specifically:

1 - better transition from gen start and stop to battery.

2 - simply start gen cycle button on the web monitor.

3 - programable warmup and cool down for the gen.

All of which I think would be MAJOR improvements.

Overall, though I am happy with the EG4 lineup.

I am thinking about investing a different gen start/stop system, something that has the above-mentioned items.  I just hate the idea of adding another "hang-on" component to the system that I think should be able to do what I want.  If it can't be done then so be it, just tell me and I will look at some other way of getting what I need.

Just my two cents.  🙂

I agree 100%, if it can’t be fixed let us know so we can make decisions, but Eric telling me they are still looking at data is simply blowing smoke, I don’t appreciate it much.  

Since this is my first system I don’t know if it’s a problem that all inverters suffer or just EG4, if it is EG4 I will move on to another brand that can get what I think (I could be completely wrong) is a simple operation for an off-grid inverter working properly. What’s so surprising is this issue wasn’t stated in any of the many reviews I watched before buying. 

@eg4eric Hi Eric!  Any update on the gen issue?  Can you give any update on progress towards a firmware update or if y’all have been able to reproduce the issue in the lab?

Just adding another voice to what I believe is the same chorus of problems: my 12000xp struggles with generator switching, though I actually find switching from battery/solar to generator to be the worst.

My typical scenario: running about 6kw on solar + battery heading into the shoulder hours. When I flip on my generator (inverter rated at 9kw running) to the help cover any difference and keep the batteries topped off, the inverter switches from EPS to on grid mode and I get a momentary blackout. Every load power cycles, and the full surge requirement is routed to the generator (gen boost is enabled) which causes it to overload. 

The generator tie in is useless unless I shut off all loads, then introduce the generator, then turn things back on one by one.
