I have a Multiplus II 3000/48.

It works well. I recently enabled AES Scan mode.

Last night I wanted to use the single GFCI outlet I have connected to AC out. The outlet was blinking yellow, then green, yellow, then green. I thought, oh dear, I have a ground fault somewhere, and went to bed frustrated.

Today I figured I would have to open up the outlet and figure out what went wrong, as it was still blinking when the breaker to it is on.

Just before I shut everything down to unscrew the outlet, I realized that the blinking was correlated to the hum of the inverter that changes pitch every two seconds to scan for loads!

No fault! And, thankfully the light in the outlet is not pulling enough current to tell the inverter to stay on.

PS. AES is not a good name, IMHO. I thought it was encryption related when I first saw it. AES = Advanced Encryption Standard to nerds, not Automatic Energy Savings

:)

Yes, I can change some AES behaviors. It was just surprising to see the GFCI reaction to it, especially before I realized what was going on, so I thought I would alert others.

Multi-colored blinking lights on GFCI outlets are not (usually) a good thing.
