I guess that depends on how you define "really low". The lowest idle per watt I've found is the Schneider XW. The low power idle doesn't really seem to be a difference of low vs high frequency though. The Sol-Ark is high frequency, but its idle power consumption is about on par with low frequency tier 1 devices (roughly equal to victron). However, when it comes to conversion efficiencies the high frequency units do have the theoretical capability of achieving the highest conversion efficiencies (lowest losses). The sol-ark has the best I've seen, but its still only a tad bit better than the Schneider. I think that any whole house off grid residential system would be wise to get a low frequency system, unless they carefully plan their system around their needed surge/inductive loads. The Sol-Ark 12k is actually only 9k from inverter/batteries, and while they claim a surge of 16k - there's some funny business in that number that involves combining power from grid or generator. I've seen a video of the Sol-Ark 12k barely passing 4500 watts on 1 of the 2 legs (only around 2500 watts on the other leg) and shutting off within like 2 seconds. Sol-Ark's actual surge capability is shit.
I'm trying to get reasonable price, good surge, good idle power, good conversion efficiency, good warranty and robustness. Good support would be nice, but can't have it all. So far Schneider is ticking all my boxes the best. I'd rather pay a bit more to have more of those boxes ticked well.
