The wifi dongle did allow access.. I had SA connected via the wireless dongle. But when I noticed the unsecured network ssid wouldn't go away, I disconnected it. I was shocked.. you just connect to it and via the eg4 app (without sign in), you can local connect and change any of the inverter settings!
Any update on this?
Just arrived 5 minutes ago
Party time! I really like the LL-S's
Have you been able to get these batteries installed and talking to SA with your other LP4s?
The WLAN (hardwired) dongle does not support LocalConnect, which means SA does not work with it. I think SA is adding a item to their backlog to seek alternate ways of connecting, given that the Wifi approach is kind of a "debug" mode. For now, no SA for me until that is done.
I use the wireless connection and it works just fine.
Did you get your new batteries working with SA (with the original LP4s in the mix too)?
No,
@EG4_Jarrett did you ever get a chance to dig into this? I'd really like to be able to query the inverter directly using RS485, in addition to using the wifi dongle if possible. The only RS485 pins I've found that are referenced explicitly are pins 1/2 in the BMS port, but those don't seem to respond to input register query commands. I expect those pins are setup as a modbus master in order to query BMS devices and aren't going to act as a modbus slave.
Amazing. Thanks so much for sharing, and sorry I didn't find that post in my searching.
I have some hope that it's possible since Tip #2 on page 7 of the RTU protocol manual talks about keeping your polling interval above 1 minute if you're trying to use both the wifi dongle and rs485 at the same time...So my wifi is entirely disconnected... the security on it is atrocious. It broadcasts an unsecure wifi network that anyone can join. So I connect to the black and white wires for the RS485. I'm not sure how you would 'share' it.
