I have 2x Power Wall 2, SolarEdge Inverter, TEG 1. Installed March 4, 2020. Monitoring app shows batteries charging during day, and discharging also when house load exceeds PV output. I set my power reserve at 40%.
I don't understand why it doesn't pull power off the grid to feed the house instead of discharging the batteries under low sun. From what I've read, the batteries get charged then operate after the sun goes down. Also, not a single backup is listed in "Backup History" since installation. That's because the batteries haven't powered the house (yet) during an outage. Tesla Customer Support says the error listed is "High Surge Current" putting the Power Walls into "self protect" mode.
I have too much in-rush current and I should turn off a few things. This escapes my logic as nothing is starting up, no motors, no compressors, etc. I'm drawing approximately 1300 watts and Tesla says I'm carrying too much load. This has happened multiple times, the last being a 3-hour outage. I was told by one tech to cycle the on/off switch 5 times on each Power Wall to reset the overload.
That did nothing. I was told to manually force the transfer switch by peeling back the label to expose an access hole. There was no switch because the "dead panel cover" was installed upside down. Had I stuck my finger into the hole I would have contacted one of the bus bar lugs. Something is causing this "overload".
After multiple tries, I finally have the installer finally coming out this week for an on-site look. During commissioning, they never did simulate a off-grid test, so I suspect I have had a non-working Gateway from the beginning. I have simulated an outage by throwing the 200-amp breaker feeding the house off. Installer says I have to wait 5-minutes before it turns on. I said I waited 20-minutes before I gave up.
Tesla customer service says overcurrent fault is unknown. Bumped to tier 2 support, after weeks, I have to call them for a status report. Same answer, I have a high surge causing the power walls to go into self-protect mode. Has anyone else experienced this situation? I fear the technician will be scatching his head. Thanks!
