Im having a multiple issues w my inverter. ill start w the issue of my inverter overcharging my batteries. it will fully charge the batteries then get the voltage over 60 i believe disconnect and cycle like that until i kill the solar. this only happens w solar. if i use my generator itll just get them to 100% and then stop charging them. my batteries and inverter are bmsed. im not sure how to fix this. ive attempted to reach out to the manufacturer but they are awful w customer service.

Wasnt directed at you. More directed at the guy who seemed annoyed that i would ask for help on a solar forum.
Will try thank you
Lots of info here.
I have mine set at 90 minutes. I'm also using automations in Solar Assistant to reduce charging current as my packs get full.
My generator runs at 120 at around 120amps going in to my batteries. My solar run at 384v w maybe 50 at best going in
What does solar assistant do exactly. Aleo what would u set the batter full recharge voltage point to
For some reason i cant go past 52.8
Hmm. There goes my idea lol.
Let's you monitor your system in near real time, charts data, allows you to change basic parameters.
Somewhere around 53.5V.
First I went fast assuming the video could b paused. Now i know otherwise. Kinda weird. My bms is disabled right now. I believe it was on sla. I had a lot of issues getting the bms to even b recognized on my inverter. Ultimately i had to set my batteries in pylon and used CAN and UZE. The only part of the bms that made any sense here was i had to use the Can/485 port. I tried using the pylon setting on both 485 and can and i would get a error.
Also do you know if each pv jnput can handle the 500v 22amps? I have 10 400w q cells in series about to add 10 more in parallel to that (would b more happy about that if it would stop over charging via solar but its kinda needed) the v and a at mpp would b 371.3v and 21.54. That setup would just get me incredibly close to the amps max (in a open circuit setting) on one of the pv inputs im just wondering if adding more was possible on the other pv input
My gen1 (round) screen srne10k overcharged like this sometimes also, didn’t matter if comms were enabled or what inverter settings were, my batts would eventually disconnect. This would happen more often when I had alot of PV coming in and not much load. I added more circuits to my solar panel ( I put every ceiling fan in house on the solar circuit and left them on all day) I also added several other inductive (coil magnet) loads like my wife’s backyard garden waterfall pump, it use to be on a timer, I just let it run all day. After I put more loads on the inverter it got better about throttling down all the pv power coming in. It’s almost like it couldn’t find anywhere to dump the power so it was over dumping into the batts. That gen1 eventually had a board failure tho, this gen2 doesn’t do that. I hated that round screen srne10k.
440v
Ill take a picture later on as im not home right now. I do have that software and it communicated fine. I dont believe its a bms or settings problem since even without the bms it would still overcharge even if i set the absorb and bulk at 55 it would still go past to 59.9
Did you figure out cold weather calculations to make sure you don't go over 500V?
Have u had to put the extra loads on the new inverter? To me it just seems like a bad onboard mppt which just has no idea what to do with the excess power.
