Ahoy! I have a 12.24kW system in Massachusetts, and my inverter throws "Arc Fault Self Test Error" basically every day. I've tried working with Tesla support but they either ignore me or that I should ignore it. Every time the self test fails, the inverter shuts down for a few minutes, so I'm...

Any luck with the high pitch whine? On my Delta install the whine was coming from the rapid shutdown modules on the roof, not the inverter. (I've since replaced them with another brand of rapid disconnect and am much happier)

Hi folks, sorry to drag this from the depths of yesteryear, but I'm curious if anyone has gotten sufficient resolution yet? I also have a Delta M10-TL-US, also sprung on me what it was supposed to be SolarEdge. I never made over 8700 watts. And have Arc Fault Self Test Failure showing up in the...

Ah okay. C'est la vie. I have been able to read data from the inverter via a MODBUS connection (on pins 7 and 8 on that ethernet port), but I haven't seen any obvious way to read the contents of the system error log. Things like these, and the string voltages/amps on each MPPT:

@aesculus were you able to make use of the ethernet port inside the delta m-series inverter? I have an M10, and I tried the m professional app and the m tool app on an iphone, as well as the m professional app on android. I tried making an account on the m tool app, the m professional app on...
