I notice the question was about "different ampacity ratings" found online. Hence how coincidentally I ended up on this page.
As researcher by trade I am rarely "happy" with what I find online (and in books alike): Actual "hard" Thinking for yourself, no research (or even less) can replace.
Take...
Not in different places, lol, a tiny house roof isn't the size of your roof. :LOL:
They sit right next to each other, four rows of two, like on the very first photo in this thread.
Given what FilterGuy kindly suggested, I am going to wire each row of four sitting behind each other, in series...
Hi everyone,
I've been waiting half a year to get all 8 panels delivered from amazon.
Got them on the tiny house roof now.
We have a few days of sun forecast (in rain I won't be on the roof, no).
I am wondering if my want-to-have array connection is doable like this? (image below)
It will be my...
Hey Tim, "23.7kw roof mounted solar so far"(?) - why do you need so much power?
And 2) did you not prefer distancing them for airflow/cooling?
And 3) Do you have enough solar-only power year-round, day and night?
(I have only enough day and night during summer, and enough day-only during winter...
" A system that did not convert from DC to AC and back to DC would have the potential to be significantly more efficient. "
This bit is exactly my point, yes FilterGuy! :)
I'd like to refrain from converting my solar input DC to Inverter AC, and back to Bike battery DC. :rolleyes:
"
For EV...
Who said such?
Not me.
Not FilterGuy.
We believe in "or alternatively switching it to charging the EV battery, at will".
Ideally, smart charging (fixed current, fixed voltage, SOC charge limit, ....). :)
Technically easy. Hence why I am surprised why I cannot find online people who have been...
Yes, I like FilterGuy 's connection a lot. (y)
The other is not "mine" Rodrick, the question was what you think.
FilterGuy 's connection is beautifully efficient, doesn't need more wiring, needs less connectors, maybe not even a fuse, and most importantly, it stays within the design needs...
Hi Dave, I know your post is old, but how did you get on?
How I found this post? I searched the forum for "72V on scooter", and 4 posts came up, relevant is only this one, yours. :)
I have only just bought my first electric vehicle, and it's a scooter/motorbike type. Fat wheels. From China...
Excellent, both of you. :)
Absolutely yes. I run everything I have through two breaker boxes (one AC, one DC, I wired my house for dual use), and the small stuff through a fuse box.
Utility box explained:
"
Yup.... I was"
The early bird catches the worm. - But then: Who would want a worm...
Now I was just wondering if solar panels in series can be wired "mid-point" like so?
As opposed to how you showed?
It would reduce my cable and conduit needs :)
Hmm, this too I don't even understand. :unsure: (sometimes I have been wondering if I am developing Alzheimers... but a woman with an Alzheimer aunt in her family said: "No, you would be very different!" :)(y) okay then).
Well, after FilterGuy's suggested connection of the 8 roof panels, since...
Very important points, yes! Thanks. 100V is not for the faint-hearted, I've seen in videos that much lower voltage can kill you.
What I thought is, once I have all necessary items (missing still):
- just before darkness, connecting P1 to P4 in-series, and P5 to P8 in-series
- because of low...
Excellent again FilterGuy :)
I agree with the loss ratio also. An inverter is far worse than a DC-DC converter.
But: Have you used one, or found one, that reliably converts from nominal 25.6V Lifepo4 (actual most times ~26V) UP to 86.4V?
In my (very limited) experience such BOOST converters...
