That's the one I bought! I like all the info on the screen.
After spending $2500 on used panels, it seems like spending another 4% to test them makes sense before putting them on the roof or waiting too long and upsetting the seller with any potential claim.
We lived for the last year with no L2 home charger. My EV has three years free charging at Electrify America so I would just take it there. My wife's got plugged into a 110v outlet whenever she was home. Her range is 200m on a warm day and she rarely had to top up at EA. When we got the L2...
My original goal was to get bidirectional charging set up with something like the dcbel r16. They got UL mid-last year, but aren't in general circulation yet. And few cars support the necessary ISO standards. I think the VW id.3 is the closest to something I'd want to drive at the present time...
I don't think I've seen much conversation about firewalls, though there is some implicit mention given the "isolated networks".
It's pretty easy to build a router that has multiple network connections on it. If you have a public internet connection, keep the router manufacturers and software...
Apologies for the late reply (first post here), but wanted to add $0.02... Agree that microcontrollers can provide no-frills intimacy with the task at hand and the task here is pretty tightly scoped.
OTOH, a "larger" rPi-based system has the benefits of language and library support. For...
Same with the Audis on cruise control. I think that's become pretty standard actually, so you won't be embarrassing yourself to teach them. My spidey sense is they are training us all on semi-autonomous driving, one step at a time!
Kubernetes even better. Docker containers are based on Linux cgroups, which is boosted setuid. Single kernel means much leaner footprint and even lower energy usage because there is only one kernel processing interrupts and no expensive superprivileged mode context switches as with hardware...
That's great, thank you for taking the time to share that much detail in your posts!
I live in a mountain state where the grid is spotty in many areas. I live (for now) in a suburban area with relatively new grid infra, but have started watching the power lines when I travel regionally. It's...
I'm interested in the first time they drive this on a slushy wet interstate that has been salted. Seems like this is going to build up a conductive layer cake from hell between that fatty exposed terminal and the frame. Because one would presume they also use the frame as their ground...
Admittedly what I’m after is not touching the brake pads in normal driving, but also know it’s impractical to regenerate to zero. The Tesla blends the brake at the very end of the stop cycle and does so without the tiny lockup at the end of the process. They did that right.
The original Audi...
Yes, without the battery and just a GoodWe grid tie inverter, 4.3 years. All systems including $5,500 in costs for racking, installation, engineering and permitting (it's a metro area). If I can get that down, all the better. Note that 4.3y is just the amount of time to recover the numerical...
I was lucky enough to set my servers loose on the last hours of the Parler hack. Had something like 500 Docker containers running, would have 10x more had the date happened a few weeks later. Got myself in to the 40th percentile of contributors in two hours.
"Ask not what your country can do...
I was also wondering this, bought one of these pallets that arrived last week and I probably ought to test the panels.
Want to find something fun for my 13yo to do with them as well before they go on the roof. Not all of them, of course!
Admitting my heart skipped a beat just there... I thought you wrote in your equipment!
I really want to see an inverter be able to host small docker containers, like one containing HA.
A little OT, but is anyone cautious about having that kind of density concentrated in a single footprint? Or is the LiFePo chemistry so stable that it's not a concern? I can imagine pushing a flaming half rack out of the garage, but not a full rack.
Don't want to be dramatic, trying to learn...
I think I started with this idea a year ago after my mind integrated that a grid-tie inverter merely needed a 240v1p space on my panel. Check! My house has a 225a panel and with the exception of inductive loads, 5kva backfeed from the AIO would be more than sufficient. And I didn't mind...
Many will say that large language models (LLMs as they are known) are good for reasoning about referentially consistent language that they were trained on. They can probabilistically distill and expose nuanced possibilities from such language through probabilities, but do not have an actual...
Our personal EVs don't have one-pedal regen, but I drove a Tesla 3 rental that had it for two weeks and loved it. With a little practice, I rarely had to use the brake and never had to guess whether I was engaging the brake pads.
That said, I also drove Nurburgring in a different rented Tesla...
Aha! This makes perfect sense, thank you! So not just about connection hygiene, but knowing where to monitor.
Good point, my AHJ probably requires them as I'm in a metro area. And if I need them, then my decision kind of gets forced before I learn about the details.
That's something I was also...
That's kind of what I've been thinking too, but wanting to learn about it all the same to help with inverter selection.
My ideal inverter would have some kind of external integration options. For instance, Home Assistant internally uses something called "Event Driven Architecture". This is a...
Hi I am trying to finish specifying my system and need to learn how to choose panels.
I'm using NREL SAM to configure the system, but choosing a panel so far in my journey has been more about looking at a couple of online vendors and searching by popularity for configuration prototyping. Now...
That was a very satisfying read, thanks. You have some serious analog chops. I imagine your remote compound is close to a long enough runway for the occasional turbine powered air taxi to whisk you to emergency jobs that few can comprehend. Please don't ruin the fantasy if that's not true ;)...
Wow, I did not know about these suppliers. Those are really great prices, thanks!
So are folks mostly just shopping for $/W and (as @chrisski notes) by size, then using the electrical parameters to configure strings?
It's a five-sided trapezoid in the 750 sq foot size range before subtracting...
I am building a 10kW solar system for my residential home in Colorado.
Last night. @Hedges was super helpful in steering me on panels, and also got me thinking more about my rather lazy approach to batteries.
My past experience has been with a APC Matrix 5000 for computer usage. It suited the...
I think I realized I'm going to spend the extra money on Sol-Ark after our conversation last night. They have a battery list and I'll cross-reference that with line card of suppliers such as CC, thanks :)
I'm more comfortable with these kinds of things, it's pretty easy for me to debug this...
