Probably just my salad as usual, but maybe I'll splurge on a veggie burger!

Tried this but it didn't work with what I have available. Guess I'll wait till Friday when the sungold cable arrives.
Oh, and I got my tracking info and the batteries will be here next Tuesday.

Hmmmm... did you use an FTDI USB-> Db9 cable?
I had a heck of a time figuring the right pin numbers .(kept counting from the wrong end of connector etc.... I could still have it wrong.... maybe I'll try to make a drawing schematic...
The RJ11 only having 4 wires and not using pins 1 and 6 is confusing in itself.
Do you already have Sungold batteries?

My Solar Assistant connected directly to the batteries seems to be matching load/battery much closer this morning....there's definitely a different in "inverter values" and direct "battery values" .... we'll see how it goes forward.
It seems the connection to the battery 'failed' at some point in the night. had to disconnect/reconnect via the Solar Assistant configuration. Seems fine now, but will keep an eye on that.

follow up on cables.... I just 'built' a DB9-> RJ11 from one of the non-working cables I bought while trying to get this to work and success! will post a better wiring/connection/drawing/photo in a bit...but the connections listed above are correct (disregard the colors depending on what you are working with!) just make sure the pin assignments match/connect.

well here ya go nasty wiring diagram:

Yup, I have 2 of the wall mount batteries which I hate. They don't work well in my setup. I guess I'll be laying them down when I get the rack mount batteries next week. The specs are the exact same for both types of batteries. Oddly though the two I have are different ah with one being 100 and the other 105 and both built the same day ? The manuals are the exact same as well for the wall mount and rack mount. At some point I may just get a couple rack mount cases and transfer these into rack mount cases.

.....and of course that couldn't the end of the story right? ....
Solar Assistant and the Raspberry Pi seem to be randomly disconnecting from the battery and I have to go to configuration and disconnect/reconnect....
...and so...after all that....I've switched back to 'inverter values' which at least doesn't disconnect every little bit...

a tip for everyone using Solar Assistant device, is to install a wifi plug and plug the pi unit into that. Solar Assistant has an issue where it goes down alot, so a simple wifi plug to turn it off remotely and back on will trigger the the device to restart and sync back up to the cloud.

I lost connection via usb and SA and I’ve rebooted everything and SA still won’t connect. Anybody have any ideas how to fix?
This is a HORRIBLE idea. This will corrupt your database data eventually.
Choosing reboot/restart in the solar assistant settings menu is a far better way to restart your pi computer.

Interesting. I've only been using it for a few weeks but have had zero issues with it locking up or losing wifi connection or anything like that. Only issue I've had was getting it to talk to my batteries directly and I'm still trying to determine/understand what is going on with the display discrepancies with battery/load/PV...
Choose the pull down where it says usb0 and see if it has moved to another usb port. Choose the new port or at least a different port and see if that fixes it.

I assume you pressed that disconnect and reconnect button? Still nothing? I'd unplug the Pi wait a bit....plug it back in and see what happens.
Cable didn't come loose did it? My usb A cable seems real loose in the inverter socket....

Geez calm yourself, its a simple 15 seconds, you loose 15 seconds of data maybe once a week, nothing and all data is still in the system from past. you cannot reboot remotely if the solar assistant system if you cannot reach it.

That’s what’s weird is I’ve got no other usb in the list I see USB01 initiate in the logs too, no sa option to select anything else
Set it up to allow logins via ssh or add something like webmin to control the pi like I do. Either will allow rebooting correctly. Its not the 15 seconds of data you risk losing its any database tables that are open so you can lose it all.

do you still have the sung gold wifi donngle plugged in? you cannot have both plugged in at the same time
The usb to serial converter may be having problems. Try disconnecting it at the pi computer and the other end too then reconnecting and see if it shows up. If it doesn't then choose to reboot the pi from the menu and see if it shows up then.
