Eg4 Lifepower4 battery is ticking on start

You really need an Oscilloscope on a slow sweep to see what is happening. I have the scope I just don't have an EG4 Lifepower battery.

have a scope and everything but I would need a constant current sink of like 1A and if the resistor is 10ohms, I should see a 10V drop for a period before the precharge resistor is turned off. The buzzing sound looks like activation and deactivation which I can’t explain what is happening there.

Just put it across the terminals at the battery or Inverter and set it for a 2 second/Div Sweep and the Voltage to 10V Division. You should see a slow rise up of the voltage and then something will happen that indicates what the problem is. I suspect it will reach maybe 30V and then quickly jump up to 52V when the BMS engages.
If your inverter is just clicking away then it might rise up to 30V or some lower Voltage and then just start to slowly drop because the BMS is not engaging.

Yes, someone with a problem should do this. I don’t have an issue but maybe I would like to see what the clicking is all about.

The battery BMS is being affected without the pre-charge procedure? I thought it's the inverter that should be protected so pre-charge is needed?

Or I am just being confused after 18+ pages :ROFLMAO:

Pre-charge function is for the battery. To save it from the surge of charging the capacitor in the inverter.
 
I joined this forum after hearing Will talk about the issues with Signature Solar. I had a similar problem with the EG4 48v 100ah waterproof batteries. Issues with the BMS incorrectly reporting SOC, random shutdowns. Each time I called SS I was promised a response. Never happened. I would follow up with SS asking me to do some extensive testing. Sent a 2 page email with results, never heard back. I now see they no longer carry these batteries. Seems like their MO is to ignore until you go away. Ya advertise US based support.........does no good if they ignore. It is easy to get a sea container of cheap stuff from China and sell it in the US, they have definitely failed on the support and warranty side. I for one will never buy from Signature again. Same reasons I see here.

Can you post the email thread here?
 
Hi Will,
There is no email chain as they never emailed after a couple of promises. I had to chase them down on the phone after not hearing back and the email is just me sending the data they had requested. I had to drain and fully charge 10.5kw of batteries twice and report results while monitoring. One thing to not reply, another to ask a customer to do somewhat extensive troubleshooting and never hear back. .

End result I am stuck with two 48vs in parallel that cannot report SOC correctly. Right now both are fully charged, one reports 84% and the other 92%. Also one cuts into "protect mode" every once and awhile and goes silent on Bluetooth a lot more than it should. .

What voltages are you charging them at and what kind of measurements are you getting on the Individual cells?
I am assuming the Bluetooth software shows the cell info?

Thanks for the reply Robby,
Not really looking to troubleshoot, nor hijack this thread. I am done trying to figure out the problem and just accept the issues, until I upgrade and find a replacement. I will say, that the issues stem from the Bluetooth interface and the random shutdowns - nothing that charge voltage or cell voltage would take part in (at least my assumption).

may be @sten can help with that. Don't want to put you under the spotlight, but you showed the issue without pre-charge on post #77 (https://diysolarforum.com/threads/eg4-lifepower4-battery-is-ticking-on-start.41681/post-561109). If you still have the inverter, it'll be much appreciated if you do the precharge process (take one for the team)

Will, my conclusion is the some or many of the basic version of SG battery is unable to handle any kind of quick Increase (Not INRUSH) current. So to precharge or to run a hot water kittle, the BMS ticks

Sorry i just saw this message now... I have the faulty inverter still but got a new inverter today and my issue was fixed. :)

The battery ticking was due to a bad inverter? What was it trying to do? ?
 
Good question

Good question... I think the BMS ticks anyways but it was being extreme as it was having some sort of troubles when it was hooked up to the inverter. FWIW my inverter had continuity between +/- which makes sense that there was the alarm preventing the short. Next question would indeed be why?
 
Maybe we have a similar problem! I read this thread all the way back, Thanks for sharing! On Tuesday evening lightning may or may not have fried my 3 Growatt 5000 es. They charge 6 pack of EG4-LL, got 42 each 390 watt panels divided in 3 all bought from Signature Solar last July 2021. Trouble shooting the "09" error code lead me to "return to repair center. Sig Sol told me they could not repair or even recommend repair shop, Tech told me to call Growatt. Not good service, reluctantly we called it act of God and will attempt to get comped by Home insurance. Now comes the current issue. I drove to Signature Solar's compound in Tx 3 hrs from home and purchased three new Growatt 5000 es , installed them on Thursday, exact same wiring, location etc, yes i tested all wires and cables first. System came up as normal but went down with no error codes or anything. Batteries will not power on, they click then change to "Protected" status with no DC out. I attempted to isolate problems but have read at least 3 error codes on brand new inverters; #19, #80 , and # 4. Please note, this is not a "hobby" this is our off-grid power source, I will not disassemble any components or or add any resistors yet, it worked before and should again??? When i disconnect the battery bank, the batteries themselves powers up fine, plug back into inverters and it clicks 3-4 times and goes into protected mode. Please forgive if I cannot describe all these issues clearly with muh CAVE MAN grammer! Basically new inverters not working and Signature Solar cares not about it. Not the first time I have had to take several days to attempt to speak to Signature Solar's techs.

Have u gone thru the firmware update process on the batteries?

We are actively troubleshooting your issue. After a lightning strike, there are many components that were potentially damaged. I know we originally spoke with you this morning and also have a tech on the phone with you as you make these posts. I have recommended to our technician that we try the firmware update, but we will need to get you the cable to do so. I understand completely the frustration, but unfortunately we are doing everything we possibly can to take care of this as quickly as possible. From the moment you reached out to Brian at 10:54am I have been trying to find a solution for you guys and see what could still be keeping you off-line. In the event that we need to get you the cable to flash the new firmware I will make sure we get it in your hands as quickly as possible. In regard to the firmware link, you need the appropriate cable to make it work. I will stay in contact with Peyton to make sure your situation is resolved.

This sentence is hilarious, it's like he's drunk and doesn't understand it got hit by lightning and admitted that fact in the previous lack-of-a-paragraph.
