Nachtrag:
Habs ans laufen bekommen. Es lag echt an dem bescheidenem Solarpanel.Hier was ich schlussendlich genommen habe bei dieser funzenden Plug&Play Version.
Solarpanel: https://amzn.eu/d/8FkqPOG
Powerbank: https://amzn.eu/d/gpViyEH
Board: https://amzn.eu/d/i5v3CcAWenn ihr das wirklich draussen hinhängen wollt, dann empfehle ich noch:

A #rnode build for #reticulum using a #raspberrypi5 and #geekwormx1206 #ups for a #carnode or #solarnode
https://www.loramesh.org/subpages/upsrnode/upsrnode.html
Running #meshchat , four #liion #21700 5000 mAh batteries seem to run the #rak4631 and Pi for at least 24 hours. The device can be re-charged using #usbc or 9 to 18 V DC at up to 3 A via a jack or other connector. The rnode shuts down cleanly when batteries run out & re-starts when power is back, whereupon the batteries charge at the same time in #passthroughcharging -

With N = at least 2 #meshtastic alternatives sprouting e.g.
#meshcore and
#rnodes using #reticulum
it seems that a #solarnode setup is going to need a solar power source and N power outputs from that to N nodes, each one running the #firmware for each protocol.
Now we need a protocol with in-built #ota #overtheairupdate please! -
I venture to post an oddity here
https://meshtastic.discourse.group/t/solar-store-forward-pole-node-testing-24-7-operation/14956
concerning the use of #usbc to #usba adapters and the effect that can have. The section in question is "Testing using USB C input via USB A output from solar panel to prevent drain of battery by the panel" in this #meshtastic #solarnode build test. If anyone can predict if my tests will fail, that would save me time and make me learn even more than I think I have. #usbc4 #usb #usb3 -
However if one switches off the sun (lightbulb) the T-bat switches off (and T-beam switches off) - no lights on at all - the 5 V green output light is off on T-bat - i.e. the T-has not charged the battery significantly - and when one switches the sun back on the T-bat switches back on with green light on BUT the T-beam does not switch on immediately.... further testing of light cycling on & off is required. So has not been shown to switch node back on always. #tbeam #meshtastic #solarnode #tbat

#tbeam does not restart in the above setup.
I have instead tested using a #lilygo T-bat #Tbat , with a battery, connected to a #tbeam wherein the #team does not have a battery in it. In that setup the T-beam node appears to switch itself on in response to the T-bat being sufficiently charged. This behaviour is repeatable. #meshtastic #solarnode The test was done using a lightbulb as shown in the picture because the sun was not available...
-
Concerning the above: After 3 days, during which there was moderate sunshine, the T-bat is flat (the green light is off). The tbeam is at about 50% and still working... so now waiting for tbeam to drain flat on its own battery.... #tbat #tbeam #SolarNode #meshtastic

If the T-beam loses power, can it only be switched on by a manual button press?
Does that essentially rule it out as a place-and-forget solar node?
as seems to be suggested here...

Test: #lilygo #tbeam + #tbat + solar panel. 2 batteries: 1 in T-bat & 1 in T-beam. How long will this run for when sunshine is sparse? Will having 2 batteries help it last longer (panel output directly into T-beam lasted only 1 week). Why test? Can one use this as place & forget #solarnode? When T-beam battery runs out it needs a manual restart (bad for place & forget), but it can restart if gets clean 5V USB. Will T-bat solar-charge & make flat T-beam restart after it shut down? #meshtastic

Lilygo T-beam plugged into a 6W solar pannel via usb B to micro connector lasted a week placed under Velux roof window before a cloudy period resulted in the battery going flat (3.09V) due to not being charged by the sun enough & the device went into sleep mode. Not bad. (Lasts only 1 day on full battery alone.) #meshtastic #tbeam #SolarNode

No. After a day of sunshine the T-bat is still charging and not fully charged (no green 'done' light) and the T-beam is empty 3% all the while. The setup Solar Panel -> T-bat -> T-beam does not seem to work. Perhaps when the T-bat stops charging from the sun, then it will charge the T-beam but I fear not. The drain of the T-beam is too great. #meshtastic #tbeam #tbat #SolarNode Is it not logical that same spec batteries cannot charge each other?
