Dual HPWC Install

Side note, I was running both at 80A today, and the perfectly normal 60Hz hum that comes from my panels and transfer switch under the load freaks out my fiance... lol.

At my house it's the meter that hums loudly under significant load.

At my house it's the meter that hums loudly under significant load.

The meter hums also. At 60-70kW draw it is pretty noticeable.

I think the sound from the inverters while they push out power at those levels will be more significant though as they include fans and transformers that would be audible under heavy load. I plan on sound-isolating the electrical room eventually if it is an issue, as well as adding some active ventilation.
