This. Always best to first moderate energy use than to be an 'overconsumer.'
I am sure the original post meant the other inverters would be larger wattage, but the original post does not say that.
Thank you for asking. I am not looking at full off grid. My house is older and correcting to bringing it to better its insulation is far more expensive than doing the solar option as prices drop. My area is never friendly to any permits. I have done as much as possible with windows and insulation. I am slab on grade but the slab is 3 inches poured in 1956. It is stable but a huge thermal transfer. Opening the walls to add a foam board would require bringing everything up to code. Much easier to over produce than bring to new code. The Victron has 10,000 kva while lion has more than that so more inverters on buying victron. I am looking at options to get the most for my money and a nice shop for myself.
Have you checked into spray in insulation? They drill holes and put it inside the wall cavity.
Another method to impr9ve insulation with slab is have the perimeter dug out and foam the outer foot .
Unfortunately, my home was built on a pad. Although very stable, digging would require certification of the compaction and soil type. I wanted to add 2 inch foam then stucco on the outside. I also wanted to do a perimeter cement walk with foam barrier to prevent exterior temps from penetrating the slab. The new codes because I live in the national forest boundaries require so much that a full rebuild would cost the same. Going excessive solar is 1/3 the cost and if I rebuild can be transferred to new building.
