Re: [RE-wrenches] XWPro produces noise at low (<50 W Power)

I will agree but despite my frustrations, as long as you update firmware on BOTH the insight & the XW PRO inverter it seemed to address at least that issue. Once FW updated you must, accessing the config menu on the inverter, go to the “control” menu, then go to the reset, select the bottom rese

Re: [RE-wrenches] XWPro produces noise at low (<50 W Power)

Thanks. That was the feedback we already received. I think it is SOP for Schneider to tell you to reinstall firmware and reset to factory - no matter what the problem. Fortunately, we have to go back to do some more wor - they are finally receiving their generator. That will give us a chance to rec

Re: [RE-wrenches] XWPro produces noise at low (<50 W Power)

I have heard this too. Eric from SE has been cced here and the first thing I was told to due was: Set inverter to bypass (someone needs to be on site, as the inverter will shut off during reboot) Check & update firmware, RESET ALL factory defaults and reenter your grid code. If you find this a

[RE-wrenches] XWPro produces noise at low (<50 W Power)

The inverter produces acceptable noise under no-load and at loads above 50 W or so. The noise (humming/buzzing) increases drastically at low power. So, essentially it makes a lot of noise at night. Has anyone else encountered this? We suspect it is the transformer vibrating - some kind of resonance
