Charge for lifepo4 is usually 58.4V to 100%.
Will you refund people who had to purchase the cable already to try and solve issues? It should be included!I'll correct Daniel on this. Yes, we will send you the cable for free.
I emailed SolarAssitant and this was the response:The SoC is determined by the inverter. You can try using the "Emulated BMS" in SolarAssistant to see if it provides a more accurate SoC:Ah. Then @TurbineTester does Solar Assistant have editable reference reporting voltages? You'll need to edit 100% to be 56.4V. My Overkill App let's me manually set personal voltage steps for percent reported.
They are set to split phase, 180Are you trying to parallel or 120/240 spilt phase them?
If split phase, do you have 2P2 set to 180°?
Could you dm me your info? This is a bit strange and I would like to get uppity in touch with our tech team to work through this.Still getting wild voltage fluctuations after the firmware update. See picture but the range is from 107v-133v.
For what it is worth, I have had similar experience with Sig Solar's tech support. It is basically non-existent. I understand that they (like everyone else) are having trouble finding bodies, but the ones they have found seem to be just that, warm bodies, and not much else. I suspect that your issues are FAR beyond the abilities of the tech support folks I've talked to. There may be someone there who can help you, but you probably have a better chance of winning the lottery than of getting hold of that person. I just gave up and don't even bother to contact them any more, since they rarely even respond and when they do, it is not with anything helpful.I have been trying to reach tech support for almost 6 weeks, using various contact methods. First issue, my inverters are outputting fluctuating voltages rangine from 105-133 v causing lights to flicker and other wierd things. Second, i think one of my inverters may have a faulty MPPT as it is not shoing up in solar assistant when monitoring. I have solar assistant data for about 5 days showing what i am talking about. It's been very difficult and extremely frustrating trying to reach someone there for technical support with these inverters. I have filled otu two "contact us" forms, two+ weeks ago and today. I have called multiple times and been on hold for over an hour with no answer on the tech support line. I have attempted multiple times to "keep my place in the que and receive a call back" and that hasn't worked, as the call either disconnects before confirming my number or i don't get a call back. I try to answer any calls that appear to come from a 903 area code, but other calls may go to voicemail as i get MANY spam calls each day, but if they are calling and not reaching me i would expect them to at least leave a voicemail. I have not received any voicemails from Signature Solar. I received one email from a person named Travis at Signature Solar on the 4th November about the error 61 battery communication problem on my inverter and his suggested fixes didn't work. When i emailed him back stating such i never got a reply. Then i tried to also get his support through email for the output voltage problem. I have not received resolution to any of these issues and have not received any email reply from Travis since his initial email on November 4, despite emailing him back TWICE trying to get help. I have also called the sales line, spoke with a very nice lady there who said she would "hand deliver a message for someone in Tech support to call me back that day" and i STILL have not received a call back. What else can i do to try and contact Signature Solar to get the help i need? I'm running out of options other than complaining on public forums and very much prefer to just get the system i paid for working correctly. Below is a sample of one of the voltage spike/drop periods from the 2p1/2p2 inverter setup i have.View attachment 125661
Additionally, for some reason Solar Assistant is only showing inverter one on the MPPT2 graphs. I assume this is a problem because I am assuming each inverter have two MPPT controllers, and that solar assistant is capable of monitoring both. I can see both voltage a current on both PV inputs on both inverters on the LED control panel, so either solar assistant just isn't picking up the second PV string on inverter two, or the MPPT is not actually doing anything. *note these graphs are a different time period from the output voltage graph.

I can see where it does correctly dial back almost all PV power once the batteries are charged but why is inverter 2 not showing on MPPT 2 graphs?
Thank you for any help you can provide.
EG4 i was getting the error 61.I emailed SolarAssitant and this was the response:The SoC is determined by the inverter. You can try using the "Emulated BMS" in SolarAssistant to see if it provides a more accurate SoC:
Let SolarAssistant perform it's own state of charge (SoC) calculation by counting power flowing in and out of the battery. This is a good fallback option for anyone who can't get a real BMS reading. It's less accurate than a Victron BMS but much more accurate than the standard voltage based readings of an inverter.
That means i'm back to the original problem that the inverters are not communicating with the Batteries correctly because if i leave the battery setting on EG4 i was getting the error 61. Now that i have the updated firmware i'll try the EG4 setting to see if they will correctly communicate the battery SoC.
This is quite understandable and can happen with mains power too. More of a concern is when the lights are generally flickering, twitching, nervous, jumpy whatever you want to call it.The lights flicker when a large load kicks in like the water tank element

I have run my circular and miter saw with no issues, I would definably investigate more or contact support. Are the loads balanced decently on the two units?So far I'm not really impressed with the EG4 inverters.
I keep getting electrical brown outs when ever i introduce a load to my system.
The other day I was using my dewalt hand held circular saw that plugs into the wall and every time I puled the trigger to cut wood the lights and everything connected would fade and almost black out.
The EG4 inverters can't even handle a circular saw without causing a brown out electrical effect.
Anyone else having this kind of a problem?
Is there a fix?
