Dang. And we were just beginning to look into one of the approved generators.

Is anyone else hearing that Tesla will no longer support generator interface with their system to charge PWs, even with the approved generators?

Finally located the discussion: Aug 1, 2017 PowerWall 2 Interface with a Generator

I did not realize you were only trying to bump-start it. Is this the purpose of the 'jumper battery'? (For those with a standby generator it would be the generator's starting battery. We have a 35AHr AGM battery kept near the Gateway to connect if needed.) I have a sense that you may be speaking...

The scenarios being discussed above have the solar disconnected. I am comparing with the generator recommendations in the Tesla Powerwall Off-Grid System Design and Installation.

So in an off-grid situation, if someone puts separate manual transfer switches between their PWs and the AC combiner panel (to control whether an individual PW is connected to the AC combiner panel or to a generator), is the PWs communications with the Gateway via the Cat5 cable of concern. It...

I don't think I realized what you were asking with the initial question, and am not clear why a smaller than input GTI is needed. Does it have to do with the MPPT of the GTI? If the generator is set on eco mode, is that ~500 msec ramp-up sufficient duration. I am guessing that would depend on...

1 SMA2000 and 1 SMA7.7; 9.7kw combined cali8484 "Most likely unless you are willing to DIY some monitoring relay circuits." No, just checking. Our generator/PW-Solar transfer switch is manual as well. Monitoring and manual control is not new for us. Also, it does not seem like that...

That is correct, and not for 22 years; never at this location. Unfortunately the Honda EU7000is is not among their blessed generators and I have not yet found out thoroughly why, whether is is power quality issues, the fact that the stock unit is not auto-start, or whether it lacks built-in...

@BGbreeder thanks for the input. Though not the latest technology, we recently obtained a Fluke 43b PQA for logging PW frequency behavior before and during curtailment, trying to capture the occasional 65+hz shutting down solar harvesting. (We have not contacted Tesla to have this adjusted.) We...

@h2ofun with all your infrastructure, are you grid-tied? We are not, and running the generator just for loads is contrary to our goals. It may be very low odds for it happening for you with 30kw generation and 5PW storage. Our 11kw and 2PW is ALL the non-generator we have. Ultra-conservation is...

@diyguy I appreciate the reply. Glad you were able to get the PW that you wanted when you did. For the (completely off-grid) user that already has grid tie class inverters, PWs, and inverter class generator, the situation is more about safely recharging the PWs during prolonged periods of little...

Did anyone move forward on the Generator -> AC/DC Converter -> Slave Inverter -> Powerwall charging proposals? I thought I had seen a different discussion on this elsewhere that included another approach, but I am unable to find it. The frequency of extended grid outages is growing and we can...
