what does it do?
I haven't I like it the way it came. There has been a few additions of info to it with out doing any thing.
It changed colors! LOL.
I did it on day 1 so I didn't use the old firmware for long enough to appreciate differences beyond colors.
@EG4_Jarrett is there a way for me to remotely tell what the IP address is of my inverter's dongle? I'm not at my cabin, and my solar assistant is timing out trying to connect to the inverter over the local wifi... I can't check the IP from here to tell if the device IP changed 
.
edit: nevermind! Apparently I needed to remove and re-add the inverter and logger serial and it seemed to connect successfully now.

Firmware update was no go. Same Issue. As soon as the batteries hit 19% they start charging from the grid at about 500 watts and AC Charge is Off. If I set the On-Grid Cutoff to 25% instead of 10% the batteries will stop discharging at 25% as expected but then will still start charging at about 500 watts. At this point I don't really care about the whole 20% thing except that I am missing out on 3kWh of power. I just don't want these to be charging from the grid during On-Peak times if the batteries get down to 20% before Off-Peak time.

I am from Germany. Don't mean to come off rude
Can you PM me your station name?
So I have two 18kpv inverters connected in parallel with grid inputs to both, running in "off-grid" mode successfully for a week now - this is where the off-grid option is selected on both inverters. My understanding is that this setup is required in order to have "self consumption mode" or basically solar->battery->grid.
They're configured to discharge the batteries down to 10%, at which point they should switch to grid.
The weird part is that, it's been a week of cloudy days, and my batteries have drained a bit each day, and last night they got down below the 10% mark. When it got below 10%, the grid presumably kicked in; however, the inverters stopped reporting *any* load, and did not indicate *any* grid input was used.
What gives with this? This is super strange, misleading, and confusing!
Graphs - notice that grid power stays pinned at 0:
When the sun came back out this morning and charged the batteries above 15%, it kicked back over to SBU as expected (which is great), but there was zero indication that the grid was even used at all...

Where are your CTs installed?
I don't have any CTs installed...They didn't come with the inverters - where do you get them? Is this required in order to actually see grid measurements on the inverter?

They came in the small white box. Check your inverter box. It's right on top when you open the 18Kpv box.

That was 8 months ago. Guess my memory was wrong.omg no way
The only thing that was in that little white box was the wifi dongle!
Maybe I completely missed it like an idiot though. I'll check on Thursday when I get back out to my cabin - I'm hoping it was in there and I missed it, otherwise I'm gonna have to contact signature solar and hope they can send me 2 of them (one for each inverter)...

You won't be the first one to misplace the CTs. I did the same thing
@SignatureSolarJess if I'm unable to find the CTs (or if they somehow weren't included in the box at all!) do you think you could help me get 2 replacement CTs for my two 18kpvs?

Hi @Shinzul I can absolutely help! If you'd like to reach out to me at engagement@signaturesolar.com I can get you taken care of!@SignatureSolarJess if I'm unable to find the CTs (or if they somehow weren't included in the box at all!) do you think you could help me get 2 replacement CTs for my two 18kpvs?
Trying to Figure out my solar panel inputs to An EG4 18kpv
32 panels 370w each panel.... 10.92 amps each.... 41 v each panel
each string would have 8 panels in series..... 328 volts 10.92 amps
wired in to EG4 18kpv.....
mppt one 328v 10.92a
mppt two 328v 10.92a
mppt three 328v 10.92a
mppt four 328v 10.92a
Would this input arrangement be acceptable to the EG4 without burning it up?
Help appreciated

Yes, that's fine

Just to point out the exact configuration would be string one and two into mppt 1 and then the other two strings into mppt 2 and 3
