I think there may have been a loss of power for 10 minutes or so.. the inverter should have been utilizing battery power exclusively at that time. Not sure why any input surge did not trip the input breaker but caused 6000ex to fault

I'm posting this in general help to see if this a general type of issue during freezing nights. Our eg4 6000ex failed last night. I had to restart the system for the first time in almost a year of deployment. The error prior to restarting system was the fault code 51 (over current or surge) ...

Hi Tarek, Have you resolved this issue? For me, I think it happens on cloudy days. It seems to me, maybe, there's some number of retries limit when the Growatt would try to start charging in the morning.. and if it's cloudy and it tries to start too many times without success, it stops trying?

What is your PV input voltage? I just started having this same issue after 5 months of working flawlessly. I have the newer control board, though, with the 67/68 firmware. How do you get it to charge again? I have to disconnect PV input, turn off Growatt, turn off EG4 lithium battery. Then, turn...

Anyone had the 67/68 firmware and had issue with Growatt 5000 not starting to charge EG4 battery even in full sun and ample voltage? If so, did updating newer firmware resolve issue?

they primarily range from $6k to $10k from my few months of searching. I wanted to find one with bad batteries, but I paid $8k for a local one with working FLA batteries due to convenience. Thanks for the link to PRCForum!

I believe that kit comes with new lithium charger and new dc-to-dc converter for the 12V accessories.

Wow! So, you will help your friend build a lithium battery pack like this to put in his Ranger EV? I would like to tag along for the ride. I don't have any experience building battery packs. I saw that you used a bms that can discharge at 300A ? From my readings (and I don't know how accurate)...

Has anyone done or looked into converting existing FLA batteries on Polaris Ranger EV UTV/SxS to lithium batteries? It looks like the lowest cost "kits" are around $2800 for 105Ah 48V... that looks much better than some of the $5k to $6k kits. Wondering what gotcha's there may be..

FYI, I resolved my hardware issue by replacing the unit with a new one. As I suspected, something (maybe a relay or contactor?) was preventing my Growatt from waking itself up in the morning when PV starts.

Resolved: This was a hardware issue. I replaced the Growatt with a new unit and it correctly started up in the morning when sunlight brought enough voltage/amperage to the unit.

He said firmware "61.13" for the 6000ex.. did he mean that or 63.13 (which is the latest) ?

I only have 1 Growatt, so I don't know if you can set the Scheduled AC Output option separately on Slave 2. If you can, then that could save you from manually flipping switches daily? I believe it's setting #50

Yes

Okay, I got the screen working again by reflashing the 61.08 firmware. I also noticed I lost the ability to set setting #11 from 10A. I had this set at 110A with the previous firmware version. Now, I can't change it from 10A. The voltage controls still do not use %. Can you please check your...

Help? @akitawpo , I updated the 63.13 firmware first and then the other folder's 61.08 firmware. After that my LCD screen went blank. I recall someone, maybe you?, had the same issue?

I have my GFCIs trip when my 6000ex use grid power. The GFCIs' subpanel is only connected to the EG4 subpanel at the main service panel: This thread

Does this firmware give you control of the back2ACgrid using % instead of Volts?

are you using the 63.13?

all, I'm confused with the mixing of 6500ex and 6000ex postings. For our 6000ex, is there a black vs grey terminal bonding differences? If so, what terminal are people referring to? Also, it looks like they split the firmware to 63.13 for House/Cabin and 63.11 for RV/mobile applications

?? I'm saying i've CORRECTED all the bonding in all the subpanels and the issue with GFCI breakers tripping still exist when the EG4 pulls power from the grid. I've only got 1 bond now, at the main service panel

I think he means the flicker is still happening after the new firmware. What are you looking to fix with the new firmware?

Thanks for responding. I've corrected the grounds and neutrals in the other building's subpanel by separating them in separate bars. The issue remains the same though (before correcting and after correcting bonding). The GFCI breakers and outlets will trip when the EG4 inverter pulls power from...

Still no success with the latest new firmware for our 6000ex?

Thanks, are these GFCIs breakers or outlets? And are they serviced by your EG4s' output power? I'm hoping my issue with GFCIs tripping may be fixed along with the dirty sine wave fix in the new firmware... but tech support told me to wait as the new 6000ex firmware does not quite work. Also, my...

I was okay with the troubleshooting process as I understand there are different levels of user expertise and we all make mistakes. But, once customer service cannot fix the issue with firmware update and turned me over to Resolution Team, I have not heard back. It's beginning to feel like a...

Do you know why they would only trip when the EG4 uses grid power, and not when it uses solar and battery power? Also, these GFCI breakers and outlets are only "sharing" connections with the EG4 at the main service panel (they are in separate buildings from the EG4 subpanels). Or are you saying...

Has anyone had GFCI breakers and outlets consistently trip upstream or in an adjacent subpanel from the EG4 AC input when the EG4 is using grid power?

what gauge wire do I need between these and the AIO ?

I have an AIO with one PV input and 2 parallel solar arrays (each about 10A). AIOmppt charger is 27A max input. I also have 2 inline fuses for the 2 parallel arrays. I've seen a video of David Poz who just connect the 2 PV wires directly in the AIO's PV input. Is this a good idea? If I need to...

I've been patient dealing with Signature Solar's troubleshooting process even though I keep pointing out this is a hardware issue. Now that 2 months have passed and I tried their firmware software update without fixing the issue, their warranty department has not contacted me at all. I'd like to...

did the firmware update cable come with your 6000ex units? or was it sent separately? I tried to update after installing the driver in Device Manager, but it says "can not open serial port". I'm using a couple of cables (one is yellow, one is black) which either came with the 6000ex or the...

Thanks for your response. I saw the lights flickering issue but thought those were the lights serviced by the inverter. I have lights in another building flickering. I will also check the bonding.

I installed a single EG4 6000ex inverter along with a rack of EG4 batteries in my garage building. I'm hoping to get some feedback/comments about these issues. 1. We found that the subpanel in the garage had neutral and ground bars/connections bonded together even though there were 4-wires...
