While I wait for (2) more tax refunds, I've started to tear into the wall where my critical load panel will be installed. In my case, since I'm looking to supply power to the whole office, its more like my "everything but my welder" panel <smile>.
So... what we are starting with:
This is a...
Thanks. I was under the impression UL actually did testing as well as standard setting. Thanks for correcting that understanding.
I love that you have many options to meet different need profiles.
Perhaps it would help others if you incorporated most of the above into your website? e.g...
Well, my Federal tax refund has arrived, now just waiting for my state and an amended 2022 Federal refund. Time to review what is needed for Phase 2:
(Snitching from my spreadsheet, please forgive the cut and paste)
This list was put together about 6 weeks ago, with all parts being purchased...
Because having to use 2 boxes instead of a single one just seems odd? Because Midnight MPPT controllers can handle 600V vs. Victron's 450V? (and perhaps have that 48V buffer Midnight is famous for where the unit shutdowns over 600V but does not fry until over 648V). Because it would be nice...
Love that its a single box for 240V split phase for us North Americans. This should be a wakeup call to Victron - they need to come up with something similar.
Lots of thoughts, mostly since I'm in a somewhat similar environment in NE Missouri and am probably all of about 2 months ahead of you on the learning curve. That said:
When you kill your Pb based batteries, which you will in a year or two, invest in LiFeP04 ones. Cost about 2X your Pb ones...
LOL - screen vendor wrote back. I guess this is typical of their "12 months of technical support" advertised. Their response: "You need to adjust the Raspberry Pi configuration". *sigh*
Hmmm. Officially stuck. Twas fun trying though.
Between the Victron Connect app on my iPhone and iPad, and the remote console allowing me to web into the Pi, I'm not really sure what the point is of having yet another interface. Starting to feel like just more cables, more power supplies...
A bit of progress, kind of. Resolution is apparently being set at boot time:
cat /proc/cmdline
... bcm2708_fb.fbwidth=640 bcm2708_fb.fbheight=480 ...
Now just need to figure out how to change that. /boot/cmdline.txt doesn't do it.
ok - it can be set by adding:
framebuffer_width=1024...
OK - will use this post to keep track of modification I'm making - all of which will need to be repeated after an OS update should one ever be done:
<from a newly burnt microsd>
Connect keyboard and display to Pi, boot it.
cd /opt/vi*/sw*/
./resize2fs.sh
passwd
cd /etc/ssh
vi sshd_config...
Ah, a few other tidbits I'm finding:
/opt/victronenergy/swupdate-scripts contain a number of useful shells. "resize2fs" for instance will expand the root filesystem to use more space on the Micro-SD card. I ran it and root when from 91% full to 22%.
Also, the system has "vi" as an editor...
Quick note, the Victron GX Touch 5" uses 800x480 resolution, the 7" (which we are trying to emulate) uses 1024x600 - so if we can get that resolution working, perhaps other things will fall into place. (e.g. "Fix what you know is broken first").
OK - received the $37 touch screen. First photos, because everyone likes photos:
Unit came with a small bag of screws, mounting brackets (kinda), a micro-usb to usb-a cable, and an HDMI cable. Really didn't expect that HDMI cable with a $37 unit and wasted $10 ordering separate one...
