I am not completely off grid. The house load overall is too great.Very nice. Are you completely off-grid? The Generac does not charge the PW, does it?
Timeline:Nice !! How long did the whole process take from time of ordering to finished installation ?
One issue I’m still working on is the Full Battery, Day Time, Disconnected From Grid Scenario, where the Powerwalls output 240 V at 65 HZ and my Microwave Oven and UPS malfunction. What issues have you experienced?.
One issue I’m still working on is the Full Battery, Day Time, Disconnected From Grid Scenario, where the Powerwalls output 240 V at 65 HZ and my Microwave Oven and UPS malfunction. What issues have you experienced?
I am still working on the Hz issue. Tesla was supposed to set the Hz at 62.5. They did not.
GRID DOWN TEST - Currently when in "Backup-only mode" or on "Self-powered mode" with a full SOC, the gateway blasts out 65.2 Hz when it thinks the grid is down. 65.2 Hz puts all 14 of my UPS BUs on Battery, throws an error code on my AC mini-split, and makes my clocks run fast. It must be fixed. It doesn't scale down the 65.2 blast until the powerwalls drain down to SOC 96%
Can you imagine if the power went off when I wasn't home? If it were mid day with 9kw production from the PV Panels and the house load was 2 kW, the 65.2 blast would be sent to the inverters at least an hour. It would drain out all the my UPS BUs and destroy their batteries. Key point - I was surprised that the gateway didn't scale down the 65.2 Hz to something lower after the initial blast. My inverters will stay off with as low as 62.0 Hz . At 62.5 Hz my UPS BUs would begin to consume PW power and go off battery.
KY-Lonewolf, are the rest of you boxes outside the house, or in a different location?
I had to submit an online request for service. Then I had to call them to remind them of it. Then they scheduled a visit from a technician, who was, helpful and courteous, but generally clueless about these technical details. He was on the phone with the technical support team, who at first told him that everything is fine and the system is operating as designed. Only after I interrupted them and spoke to them to explain the issue, they changed the setting to 62.5. It took a lot of effort on my part, but it is possible to do.
Not sure if you had another issue that required a site visit but for others that have the same frequency issue it can all be done over the phone. The configuration settings are set remotely and I believe even if a tech came on site they'd have to call themselves to get it updated.
Yes, they had to call. I agree that it should be done remotely. I tried to to get it done remotely, but the person at the customer service line said "no"
I am not completely off grid. The house load overall is too great.
The generator does not charge the powerwalls.
However when grid down, I can use the generator to power the house while the PV panels are filling the powerwalls back up.
Throwing the breaker on the ATS causes the generator to power the house. This isolates the PV panels and Gateway so I can charge up the Powerwalls.
Yes, thank you it was very useful and I had read it previously. But it’s like pulling teeth to get it done. After about a month Tesla tier 2 support, responds via a CS person, that I need to get Enphase to change the must trip /. Shall trip frequency to 60.5, before Tesla can make the change. At this point I’m still waiting on Enphase to get back to me.
