Hooray! I got an e-mail today implying Sunrun would let me hook up the HIS system directly to my existing sub-panel rated to draw up to 125 amps when powered by the grid (twenty-six 20-amp 120-volt circuits and a 30-amp 240-volt dryer circuit) on the provision that I will use the system in...

I agree that # of recalls doesn't tell you anything about the seriousness of a recall. But the question that we're discussing is, "Does a recall basically have to do with a reliability issue for a vehicle, or could it be that actually the reliability issues involved are really insignificant...

OTH, Consumer Reports, based on reader surveys of reliability, usually rates Ford vehicles at average or below-average reliability. So, by that data and Occam's razor, it's probably that Ford is not doing as well on reliability, rather than that Ford is just a lot more conscientious than...

<<<sarcasm intended>>>: Sunrun's Field Website instructions on how to set up a "Whole Home Backup." Slide 8 at https://sites.google.com/sunrun.com/sop/work-instructions/backupmicrogrid-circuits Click on slide # in the lower left to access a list of slides. Diagram showing relocation of only...

My latestet hare-brained suggestion to Sunrun to allow "whole-house backup" to my existing sub-panel of outlets and lights (with less than 15 kWh usage per day): Don't wire/activate the HIS grid to sub-panel circuit. Instead, use the existing 125-amp breakered main panel to sub-panel circuit...

I was referring to schemes where folks want to run a cord from the 240-volt outlet in the truck bed to a plug connected or inline with a transfer switch - I'm a dummy and don't fully follow that approach. Am just illustrating that the 400 kW the battery can supply to the motors isn't available...

But if the wiring from the MID to the critical loads sub-panel (or whatever sub-panel you want to hook up the MID load to) only supports ~40 amps, that could be a limiting factor. I remember there is a 50-amp fuse somewhere in there (not sure if it's the inverter or the MID), but that could be...

I wonder if the inverter or the MID/WHB is also limiting when the system is running on power from the grid? I haven't been able to deciper the wiring diagram that I posted above for the FCSP/HIS setup, but isn't power having to pass through one or more of those HIS devices when the grid is...

That's the wife's view, too, as I noted at the start of my reply to you above. The Sunrun sales person, when he was explaining the need for a critical loads sub-panel, said, "We don't want anything to blow up." In retrospect, I interpret his remark to mean if one's system draws too much power...

I asked Sunrun about this possibility today. They said, "No-Can-Do, because a SPAN panel is incompatible with the Ford/Sunrun HIS system." The person I spoke to, who was just relaying feedback from the design folks, also said that a SPAN SMaRT panel is not compatible with their solar system...

That would be great if it were true. But, for instance, here's a Delta circuit schematic for the whole shebang with photovoltaic input. The "critical load panel" is essentially the backup panel (BUP) or restricted loads panel. I don't see any provision for returning unused residual power to...

I did give Qmerit a call. At the time, I didn't have the $3,350 additional quote for "home improvement." They said they couldn't match the $8,900 price for the basic home FCSP and HIS installation. The person I spoke to said that most other quotes that he'd heard of ran at least $14K to $15K...

Thanks for all the feedback. The bit about "Elderly Couple Disgruntled ..." was for the sake of humor. :) But I also intended to convey the idea in the post title that our house has very limited electrical needs for just an old, relatively inactive couple, not a big, young family, in...

I've gotten a bid from Sunrun to install the Ford Charge Station Pro and the Home Integration System and have signed the contract with the option to cancel up to the installation day. Yet nowhere in the contract do they state exactly what they're going to back up. I've told them if they don't...

Perhaps the Tesla techs were thinking of lithium iron phosphate (LFP) batteries, which I've read that Tesla has switched to on standard models. An article today in The Verge explains the differences between lithium batteries with nickel, cobalt, and manganese (what the Lightning has now) and...

Has anyone had trouble with folks swiping replacement antennas, or do you all Locktite them on? The 13-inch Rydonair is pretty highly reviewed by users. https://www.amazon.com/gp/product/B07BDKNQWM/ One reviewer claims its signal reception capability is within a few dB of the stock antenna...

Don't have my truck yet. Is there a direct readout anywhere in Settings of the 12 v battery voltage? I should imagine the Lightning doesn't have a "cigarette" lighter outlet in the cab. In my 2007 Honda Hybrid, I have a dual USB car charger with a voltmeter, like this (the OEM model I got is...

But the pricing criticism is related to EA being a "quasi-monopolistic" government creation throwing EVs down our throat to spuriously save the planet from that government hoax called global warming, which will turn out to be just as fake as the coronavirus pandemic. [tongue firmly in cheek]...

Then, Tesla's invented new Li-ion battery technology. Previous Li-ion technology studies, including studies published in peer-reviewed journals, show that below 20% and above 80% are harder on long-term Li-ion battery lifespan, as is running the battery at elevated temperatures. Or why does...

Very true. But it wasn't random. Geological data shows temperature fluctuations were invariably associated with the gas/volcanic content of the atmosphere - and past much higher CO2 levels lead to global warming and ocean rise. The main thing is mankind around the world has particularly...
