Are you at 0 battery current? I had the same issue and it was because there was current flowing in/out of the battery at a detectable rate. In my case I could also do system time on the batteries but could not write to batteries. I also had issues with drivers on my m1 mac but after manually...

I also had what I would consider a pretty bad experience with 6500EX warranty, but comparing the 6500ex to a SolArk 12k is not exactly fair when a single 12k is about twice as much as 2x 6500EXs.

There was another thread about someone returning their 18k and it kept getting repeated that it was the first 18k to get returned. :ROFLMAO:

I guess this makes it the second 18K to get returned?

I didn't know this and just stumbled upon this thread. It's been over a year and I'm still going to try to fill it out, but it's pretty absurd that this has to be done, specially since all the info the form asks for they have available on their end. The one thing might be that the purchaser...

Yes. The other commenters here assumed 48 Voc so I think their suggesstions are already up to spec with your panel. I have no experience with using solar panels in the cold (my house is in the caribbean) and have no experience with these Voc fluctuations they mentioned. Just to be sure, you...

@TheHappyNomads If you post a picture of your panel specs we can give you more certain answers on your best string combinations.

You want 1 disconnect for each string in this case.

What I found online for the lv6548 is that it has 2 MPPTs that accept up to 250V, and there's a V model (LV6548V) that accepts up to 390V. I think you might be confusing the watts with the volts, and you might actually damage something if you hook up those 10 panels in series together without...

Was it full pack or cell overvoltage? @Zapper77 showed a screenshot from a firmware that the max voltage set above the alarm voltage. If you had that Firmware it would be very likely to have caused pack overvoltage alarms.

Well that shunt by itself is like 9% of the cost of the whole battery, which has cells, casing and a BMS. I'm sure that if Victron sold you a Server Rack Battery it would be much more expensive than 1 EG4 + 1 Shunt. :P

Yep, 14 AWG should be 15A so you undersizing is great! Glad you got that handled and were able to make your system safer.

The 2A thing was confirmed by someone from SS in this thread. I also tried it with my bench PSU and was able to consistently go from not charging to 2A by increasing and decreasing the amperage in the lab bench a few milliamps. I'm optimistic it may just be a firmware bug and next update will...

Just to make sure, did you pick a fuse rated for the the thinnest cable in the string?

Yes exactly. The way software is usually built you increase each number individually. I have plenty of software at work on like version 2.437.0 and you definitely don't need to preallocate zeroes to get to more digits.

10 > 5 so 1.10 > 1.5

Update: The really imbalanced battery is is still very imbalanced, the process will take a really long time to get as good as the rest of the batteries I think. I'm considering pulling it out, popping the cover and using my bench PSU to get the low cell/s up closer and reduce the imbalance, but...

Did you cycle them as normal and just let them top balance during sunlight topup or did you leave them topped/charging like I am?

Some updates in case anyone also runs into a huge balance difference like me. I ran my lab bench at 56.2V for like 18 hours, but at some point I actually took the battery and paralleled it with the rest of the pack so it would charge a bit faster, then continued with 56.2V. I think it hit real...

Absolutely. I had an issue with a 6500ex and their support was subpar and the way I managed to get them to pay their attention was to complain on the forum. They asked me to do so much troubleshooting of my connections for a system that had been running non-stop for months. I'm also considered...

Where did you find this 57.1? The changelog that I downloaded with the firmware states:

The backfeeding of the USB is actually somewhat of a problem but won't damage anything. It's also easy to fix by putting some electrical tape on the power pins of the USB A side. In my case, if I don't tape those, the PI won't boot up if connected to the inverters. Everytime I did a hard reboot...

That's a good idea. I isolated the battery but left it on comms while charging so I can monitor through SolarAssistant. Everything looking good up until now. Hope this battery gets itself back together after all this.

Ok, I'm gonna charge it with my bench power supply and just leave it isolated from the pack for a few days. while the bench PSU handles top balancing. Will report back progress and thanks for all the help.

I just tried this today and my cell alarm triggered. I think I either have a super out of balance battery or a bad cell, and I'm leaning towards a bad cell. The cell undervoltage alarm triggered at total voltage of like 49.7. A few seconds later I got the SOC undervoltage alarm, but not sure if...

Unless the current of the pack is measured per cell, then I don't see why it would scale with voltage. And I did see me SoC move on mine so it is detecting current changes, buy maybe it gets measure differently. Not sure. I also confirmed you don't get boot info if the BMS detects current, and...

Some extra info from my end. While I also have the issue where currents under 2 amps are not shown, my SOC% still updates. I wonder if maybe the BMS is actually sensitive up to 500ma but the reporting is not providing the info between 500 and 2000 mA. Also for mine it was exactly 2.0amps where...

How sure are you about not being able to get boot info? I've been struggling to get this update going and I think that might be why, but I think I was misled by the video linked earlier where he was able to get boot info but then shows a current of 6 amps going (his solar did also kick in right...

I'm getting here a bit later and haven't read everything before, but I do know a bit about ACs. First of all, you absolutely want an inverted based AC. They will save you a significant amount of energy and provide a most consistent cooling experience. I read that you said that 240V ones are...

I'm upgrading to an EG4 18K soon and want to get more battery capacity along the way. I'm considering getting an EG4 PowerPro but I know I will only be able to use communication on 1 of the 2. Right now I monitor my batteries via SolarAssistant by plugging the batteries in via the USB Cable...

Reviving this late but what gauge is the wire? You can just get a fuse rated for the ampacity of the wire gauge it comes with.

My bad if I'm just stirring the pot here, but thought putting this out there could be useful. I honestly always had a good impression of Sol-Ark until reading this thread. I've gone more budget stuff myself because I enjoy tinkering a bit, but for people who asked me about solar I would...

Lol bro, I know my way around wires and electricity well enough to know what to do. This still doesn't change the fact that it's pretty reckless to ask of all that to even start debugging or getting a warranty claim through. I have no issue with having to read these values myself whenever I've...

Yeah, or have unshrouded probes cross accidentally. This is a good idea and would save me having to press the shutter button, but getting an angle where it was clear the probes were touching the PV terminals took some moving around because there's a few wires and what I think is a toroid on...

No, you should read what I wrote again. I am saying its reckless to ask someone to take pictures of their voltmeter while they're measuring these high voltages. To quote the exact wording I was sent in the email: This means they expect to you take a picture where its clear what the probes are...
