Jay, We bypassed it all. It is rated at 5kw and 7kw surge for 30 seconds. If you stack them you increase both of these numbers. When I helped my client do this, it was to get a back-up to the back-up offgrid. So, there really was not the issue with someone losing their refrigeration or water

Does any know anything about the inverter in the power wall? I never hear anyone mention anything about it. Efficiency, surge, tare loss, repairability, AC charging capability, generator support, AGS, etc. All the normal inverter questions. Thanks Jay Peltz power. > On Jul 19, 2020, at

I third what Ray says. It is also my understanding that Tesla does not allow their installers to be "subs". On Sun, Jul 19, 2020, 10:16 AM Jerry Shafer wrote: > I second what Ray says > Jerry > > On Sun, Jul 19, 2020, 12:49 PM Ray wrote: > >> There are so many really good Li Iron Phosphate

There are so many really good Li Iron Phosphate Batteries available, that are actually designed for off grid, that I don't see any advantage to using a more unstable chemistry that is not designed for off grid.   AC coupled is a 2nd huge no no for off grid, and can leave an unattended system

Hilton, Wrenches As I recall Tesla does not recommend their battery for off grid applications, they need to be connected to the internet and without that there may be warranty issues. I don't think that the off grid world and daily cycling would work well over time either. How would you jump start

There are people who are doing it on youtube but I have not looked at it seriously because it has NMC cells. It is a very nice capacity at 13.5 kwh, and good for the money. I did help a client get a model 2 to work offgrid. After we were done it worked great with a Schneider system and still

Greetings, Wrenches, I have an off-grid client who has been reading the buzz about the Tesla Powerwall 2.0. I have been reading the data sheets and manual for it and it appears to be AC coupled only. There was talk of a DC input version, but apparently that fell by the wayside. I try to be
