Sounds like a dream to me :DJust a retired old nut living in the woods. Mostly on these Chinese thingies it is not a good idea to attempt to run full out anyway.

Isnt your aio ac out ground cable bonded to an earth rod driven down into the ground ? I _think_ ac out ground and aio chassi ground plug is bonded internally so you can connect ground cable between that and earth rodSomething to be aware of. This high voltage AIO does put 62.5vAC out on the PV wires. It can lead to a hot panel frame if that frame is not electrically connected to other frames. Many of my panels are mounted to metal poles but I did have a few that were on wood based racks and those when measured to the pole mount ones is where my DMM measured the 62.5vAC. it is of a very low amperage though that would not light up a small test bulb. But I did get shocked the other day when trying to hook up my shunt and not completely de-energizing the AIO. (Pretty dumb to not always check a circuit dead before working on it).
My solution was to wire the frame of the panels that are wood mounted ones to the frame of the nearby metal poll mounted ones.
The AIO has a chassis ground that hooks to my house ground. It is NG bonded when operating from inverter and uses the Main panel NG bond when in Bypass. None of these should be connected to the PV input. How it gets the AC voltage on them is a function of the AIO's electronics and is beyond my level of knowledge to explain the path.Isnt your aio ac out ground cable bonded to an earth rod driven down into the ground ?

Just checked my unit. It has battery negative, Ac n and ac ground bonded to earth rod. My pv negative and above mentioned have 100v ac potential and 200v dc potential between them.The AIO has a chassis ground that hooks to my house ground.

I don't have enough electronic knowledge to know if that would be a good idea or not especially with a high voltage MPPT type SCC. A PWM it likely is the default arrangement.Just checked my unit.

On epever charge controllers pv negative in and battery negative out are bonded but aparantly they are not on these powmr units.
Maybe a bond between pv negative and battery negative should be made?
Im not doing that either. Its some weirdI don't have enough electronic knowledge to know if that would be a good idea or not especially with a high voltage MPPT type SCC. A PWM it likely is the default arrangement.
The manual said that the aio housing is hot during use and not to touch it.. ? not sure if they meant hot as in it is energized or just hot as in temperatureI don't have enough electronic knowledge to know if that would be a good idea or not especially with a high voltage MPPT type SCC.

I've tested a 12 volt system and next one planning for is 48 volt DC.Me too, but the eventual arrival of an EV will mean more consumption and the need for more than ~1600W of offset powered by a small 1.1kW DC-coupled array.
I’ve learned a great deal over the past 3 years with my 24V system but I think I’m ready to move up to 48V.
That allows for higher-powered inverters with more headroom which has always been the case, but what has changed is the arrival of the Chargeverter (actually the 48V Emerson rectifier in my case).
That allows me to convert my DC-coupled 3P1S array to AC-coupled with Microinverters and absorb the energy I don’t want getting exported to grid rather than attempting to throttle Microinverter output.
Then I can add a new 1P6S array to keep the battery fully-charged and the new off-grid inverter happy 9 months out of the year with the Chargeverter / rectifier to get the battery through the night even on rainy winter days for the last 3 months.
I’ve been offsetting using two 24VDC GTIL inverters but want to move to a true offgrid system powering ~60% of daily consumption (fridges & freezers).
The Conext SW would have allowed me to stay at 24VDC but I would have had to add a separate HV SCC plus if offers no headroom for future expansion so it does not seem attractive.
Any more details on your bad experience Cindy?Think before to deal with SRNE company.
Very Bad experiance with Sales people , Very bad communication skills and very bad attitude. It's too risky to deal with such people. you can't get support from such people, Internet is full of their companies bad reviews. check facebook.
You can find some other companies for solar products
where can you get this software i can't find it?How is your powmr treating you sofar @Mattb4 ?
Mines doing just fine when it comes to running my household.
The SRNE pc monitoring software tho did not want to work with my rs485-usb cable but worked fine with usb a-b cable.
Data collecting is a bit wonky and get stuck if you work with to many tabs at once in the SRNE app.
Advantages/disadvantages to the higher PV inverter. One thing I will say is the MPPT sweep for the higher PV SRNE voltage units is better than the original 100Voc model. It does not have the annoying drop to zero every 15 minutes. I wonder if the new models of the lower voltage units have corrected that now.Yeah I'm thinking about replacing my srne 24 volt 100vdc solar input for the higher voltage units so I can string my panels instead of paralleling so many. Might do that later this year I've got other expenses but I may even buy the PowMr unit although srne volunteered to sell me direct with air shipping and srne labeled one for a few bucks cheaper from China of course
Both -100 units still going strongAdvantages/disadvantages to the higher PV inverter.

Both my PowMr and the EAsun AIO's are still plugging along.
