Seeing strange alerts

[mark-miller0]

I installed Powerwall Dashboard for the first time about a month ago and am seeing some alerts that I don't understand. See the attached screenshot.

Specifically, what do PINV_a043_gridResistanceTooHigh, PINV_a067_overvoltageNeutralChassis, and POD_w110_SW_EOC mean?

Hi @mark-miller0 !

We have been archiving these alerts as they show up, and adding details as we discover them. You can check out the Devices and Alerts list here on the pypowerwall.com page.

• PINV_a043_gridResistanceTooHigh - I haven't seen this one before - The PINV prefix means this is coming from the Inverter (as you probably already guessed). From your graphic, this seems to be intermittent and not nominal. Do you see any odd behavior? It seems to be happening at night when your battery is in discharge mode or you are on the grid.
• PINV_a067_overvoltageNeutralChassis - It's not clear what this means, but it seems to be nominal (it appears on working systems).
• POD_w110_SW_EOC - This is "End of Charge" This triggers when full backfeed starts and battery is at 100%.

Thank you @jasonacox !

I am going to follow up with my installer and see what they say about the PINV alerts and will report back here with any new information.

I don’t see any odd behavior but wouldn’t know what to look for.

I would look at the Energy Usage graph. Potential odd behavior would be any unusual spikes or flapping between Powerwall discharge and grid usage, especially during the alerts.
