My understanding is that these devices are using Modbus Protocol which only allows a single Master device to send/receive requested registries. Basically, you can only have one cop directing the network traffic. Not sure, but I believe the EG4 LL version may allow redundancy.

Interesting, does the Growatt comm board broadcast modbus simultaneously (spliter) through both USB A and B ports? If so, I guess you could remove the WIFI-F PCB from the case and have room to connect Solar Assistant to the USB B port? Or I guess you are pinning from the WIFI PCB Tx to Pi Rx...

Hello, I believe I discovered that information here, in this forum. I'm not sure of its validity, I have a tendency to be overly cautious. More good information/options to consider, thanks.

Good discussion, I have a Growatt SPF 5000 ES running at 040 04 301, 041 04 301 firmware, except for the Shine WIFI communication, It's been running stable since the system was commissioned early last November, the Shine has been inadvertently freezing, which requires cycling the inverter...

I appreciate the feedback, I've done a general search concerning the dry contacts and could not initially find the information, but I'll continue to search. I'm still curious about "During bypass mode the autotransformer neutral is supposed to be connected to the service neutral.", could I...

I brought my off-grid solar project online two weeks ago, and everything seems to be operating very well. It's a small system, but I designed it in mind for future expansion. My next phase is to run grid power (240VAC) to the input of the Growatt SPF5000ES. However, after reading last night...

Okay, just let me know. I just measured the box, it's 10"x14".

Yes, I still have it. New in box, came from Signature Solar inverter kit. I just want what I paid for it, $395.00.

NEW IN BOX I won't be using a recently purchased SOLAREDGE SEAUTO-TX-5000 STOREDGE AUTO-TRANSFORMER, if someone in the Houston Texas area has a need, please contact me, I could meet halfway.
