This thread has been very informative for this noob, Im in a similar situation. Looking at buying an inverter but cant decide what I want/need. The LVX6048WP is the closest ive come to finding a complete AIO for me for the price, however it seems that it is very loud and still going through some "bugs". I need to eventually have split phase but I really wanted it in 1 unit rather than having to buy multiple units. My other option would be to get 2 LV6548s but the idle consumption is terrible on these units right now. Anybody have suggestions on a affordable solution? If I have to buy 1 unit and run 120 this year and add a unit next year to get split phase I could also go that route. Would like to get inverter and a 100ah battery for under $3500.

Doesn't appear anyone replied, maybe I'm too late to the party, FWIW:
A
single AIO that will output 120/240, 6kW output capacity, lower standby then running Two 6548's is the MPP LV-6048. I paid less than $1000 USD each, using MaximumsolarUS to supply them.
A single rack battery from Sig Solar is about $1500 USD (and expandable in the future with more in a convenient racking system)
So this is about 2500 plus fuses, disconnects, breakers, wire, PV if you like - or add that later.
This would be close to your budget of $3500.
A few comments - since I have two of these inverters and been running first one since Spring 2021, second since Spring 2022:
the fans can be loud. especially under heavy load or high PV input.
a big load (well pump) is best to be 240v so both legs get equal load, (and total amperage is less).
The units are quite large (wider) than most others.
These units have four input/output Gnd,L1,:L2,N and as such are super simple to install, connect to a subpanel.
These units have internal switching for N-Gnd bonds when inverting, disconnects when in pass through. Check your own system requirements, if you want to remove the internal N-Gnd bonding this is easy to do by removing an internal screw.
I made a mistake one day and blew one MPP comms board, Maximum Solar replied to my email within a couple days and I got a new board, (that was correct and fixed the issue) within two weeks for $40 shippeed to my door. They also emailed me a service sheet to walk me through the replacement steps, it was clear and very simple to follow. (Some members seem to have had issues with tech support from MPP, but this is not my experience at all).
There may be a EG4 model that is similar to the LV 6048, but I am not sure. you may want to check.
