The power factor point @DY_Power raises is spot on — the Starlink dish PSU isn't a pure resistive load, so your actual VA draw will be higher than the watts suggest.

Running Fogstars myself in a shepherds hut setup with a 48V Victron system, and I'd echo the reliability comments.

The BMS cutoff is absolutely the limiting factor here, and @LazyNomad's right about checking your manual first.

The efficiency angle is worth flagging too. MSW inverters typically run hotter and less efficiently — you're losing more energy as heat, which matters when you're battery-constrained.
