Bitter Lessons from the ISSpresso | Hacker News

A Hacker News discussion says coffee makers and kettles can trip some solar or battery inverters because of continuous-load limits, not just the appliances themselves.

Commenters debated whether this is a fundamental inverter constraint or a design choice, comparing off-grid, hybrid, grid-tied, and microinverter setups.

The thread notes that many solar systems are intentionally undersized versus peak panel output because brief generation spikes are expensive to capture and convert.

Heat, cost, and real-world demand shape inverter sizing, so nameplate wattage alone does not reflect usable appliance power.
