Building 2: one's a schneider xw+ 5548. The other's a dual 8kw Victron (16kw).
I have 2 5kw in the field running now. Both are for smaller home systems and both regret the high operating overhead. The bigger the inverter the faster the idle load seems to rise.
I have, by contrast, a mere 3kw on my home system.
Remember, when sizing your inverter: most inverters will cheerfully run 2x the capacity of the inverter on surge. So build your inverter to your loads, not your surge.

Quoting: creeky build your inverter to your loads, not your surge.
But as creeky and I found out, you cannot ignore the surge entirely. My 60W fridge would trip a 300w inverter because the surge was over 700w. My 500w inverter handles this surge with ease.

I use only a 1000 surge to 2000 pure sine inverter with soft start for my fridge, problem with the inverter is it idles at 1.75 amps otherwise good, still need new batteries hopefully in spring.
