No, Victron is great from what I read. Yes, you can specify a buffer... But if I turn off a 5000 watt load, and the multiplus can't change faster than 400w/s, then it will take a large buffer to prevent backfeeding some.

Yeah I mention which settings have to be enabled for that to work with grid. Essentially self consumption and “sell back” even though you aren’t selling back. And then you can choose your wattage limit. From what Ian said it can power loads. Those inverters just don’t like each other for some reason. He has other 10k’s hooked that way and it works.
The “sell back” option just enables self consumption mode.

Thanks! While looking through the document I found out I can use ess to sell from battery to grid. I didn't know that functionality already existed. Sweet!
Looks like it can do all those things.
I don't know of any zero export system that won't export a little bit. Do you? Any zero export system will get you a call from your poco
Ok I don't really understand why sell back has to be selected.
Could I ask you to please try it one more time when pv is not available? Do you have the CTs connected?

Not interested in an interconnect agreement.
If I have to, I can use a double pole transfer switch but that will not allow grid assist.

I don't have a reason to interconnect. My system in my house is off grid and the system for the shop will be off grid, I'm only interested in grid assist but if necessary I can do without grid assist.
I will have 144 Kwh of battery power here when finished, I don't need an interconnection agreement.

Yeah I tried with and without PV. The sell back option basically allows the inverter to grid assist. So instead of sell back it should be labeled “enable” or something probably.

Ian mentioned he does have video of these aspects also. So hopefully he will work on posting those as well.

I'm probably installing a 200A transfer switch on the outside of the shop with a main panel. Currently wires run thru a LB thru the wall right into the main breaker panel and wires won't be long enough. Using the EG4 18Kpv with built in transfer switch would require a side tap but inside space is also limited in some respects. I want the ability to switch completely back to grid bypassing any inverter is the main reason, I run a business here and if something goes down, I need the ability to make a quick switch.
When I started this I had already looked at grid tie in the past. My brother runs a 17.5Kw wind charger with grid tie and he got screwed when the rules were changed even with a signed interconnection agreement. Around here many farmers installed grid tie and in the last 2 years those agreements have changed and the state utility board allowed it. No thanks, I built my system for off grid with grid backup. If they don't like it, I can shut down the grid at my meter as this acreage has a 400A transfer switch on the pole when I moved here. I'll just install a genny for those times of lean PV and run totally off grid.

Have you measured the idle draw of this unit? Thanks

It seems to vary somewhat depending on the temperature of the unit. I’ve tested 58-63 watts. Ian mentioned he’s seen around 70 watts in testing.
That's pretty good for a 10kw unit wow

Definitely let us know if you pull the trigger. I want see/read more people talking about their specific installs with this. Considering the outdoor rating also this thing is nice unit. Even if you’re keeping it indoors no filters or dust issues. The fans blow through the back chamber over the heat sink’s. Similar to the 18kpv. Except this blows sideways.

Mine should arrive next Thursday. Ordered yesterday.
are you planning to use the grid interactive features?

Yes - I want to have it supply solar to cover my loads and feed Grid power in as needed - which it can do. Additionally, I want to backfeed my home grid to do zero export if possible. I mean I know it does that - but I am cautious about any backfeed that the meter can detect.
To clarify, I want a critical loads panel on load1 and feed back to the grid via the grid connection for zero export. That way when the power does go out, my critical loads are still covered.
