Just another update as it did it again. This time it turned out to be the little jumper wire for the kill switch if switch wasn't installed. (little black loop wire next to the dip switches) one end was loose, other side pulled out with a slight tug. Good luck

This is way late to help but it turned out to be a firmware update issue. I guess from talking to someone there that the systems stop and then they figure you will call for help. Then you get the update.??? Now few months later doing the same thing.

Did you figure it out I have a Min 8200TL-XH-US that just didn't wake up no errors no nothing Looks like its waiting for power but it has what it needs .

Anyone have an idea on a fix? I have a min 8200 Growatt inverter that seems to be stuck in standby mode. It's been working fine then 2 days ago never woke back up. It's got 244v AC input and DC input from 3 strings of 340 plus volts. It indicates it's in standby mode waiting for DC power (green...

I'm sure you can run a ground rod in someplace close to shed wait for a soaking rain or use some PVC pipe and hose to soften and bore in the ground then beat in the last bit. You might get away with running a 6ga copper wire say 30ft just under the ground a foot or so

Thanks thats what I plan to do once I hope to get some recharge on them after being tested (not letting them sit empty for long) But think I'm waiting to long to test them??? I did initial charge let sit and slowly working thru them (16) pretty sure my numbers will go down the longer they sit (...

The 1234 with the 4.9.2 latest version had to get code and use old version 4.8.4

I charged it as a pack to 3.4/5 with a bench power supply then added the bms to finish and balance to 3.625 then let it sit for 15 hrs then started capacity checking down to 2.8v now I'm looking to get them started charging with the a supply till I finish checking all the cells to reassemble...

Thanks for the info I was pretty sure thats what I could do but don't want to mess up new cells

I have new cells to test/charge The EBC A40L tester works great but Id like to speed things up on the charge side to free up the tester. I also have a switching power supply that is 0-8v and can do 30-40 amps but has to be in the upper volt range to get the amps. Can I use this to charge the...

Don't know what happened to original response but I got the code and changed the code back to 1234 using old version and alls perfect got the cells charged up to 3.625 rested overnight and testing 1st one now with the ECB-A40L. Sadly I must have done something wrong or I have no idea what I'm...

Well I sent everyone I could think of to get the code and Daisy from Docoan came thru. Had to put older app version on the phone 4.8.4 and with the new pass code you can open it then go to change the password again using the pass code to original 1234 (I didn't want to tempt fate) and all's...

I have watched his videos a few time good review of it. loveoff grid garage and Will Prowse channels but you have to get it to open first then the settings to actually take and not put in random numbers

I've tried getting with jk support no help email won't go thru on website tried sending thru email nothing, tried seller nothing yet either. I hear there is some code but who ever has it is keeping it secret. Dropping another 185 bucks for another paperweight just doesn't seem to pass the logic...

Ive tried uninstalling app twice restarting phone every consevable combination of password along with originals. triple checked wires and continuity of them. Nothing working it will power on but won't pair for nothing. Have no idea why it reverted to 2 cells at 5 amp capacity in the setup tab

Just set up the 24s 200 amp bms on 16 302ah cells with 3.36v on 15 cells 1 cell was 3.45 (reason for setting it up initial charge on batteries). I got it to pair with 1234 but verification was 123456??? It read total voltage and each cell so I changed password and started setup under lifpo4 tab...

Just had the same thing happen to me what gives. What good is it if you can't access it (Little help here)

I'm looking to charge lifepo4 cells/pack eventually with solar, but have to get there first. I have a 0-5v 40 amp load/charger coming for initial charge and testing. The question is I need something to finish the top balance. I have 2 power supply's already (12v 60 amp not used yet and a 24v 16...

Thanks for your reply but my is ag style roofing these bracket won't fit

I have called about the Magerack about the R brackets but they tell me they wont work as I have the rounded not flat ridge like the pic. So that leaves me with a lag bolt or a S5 solar foot style bracket. I think the other version of brackets screw into the metal rib only.

My new metal roof has furring strips spaced 2' apart the width of the roof going all the way up. The new system I have to install has to be installed in the landscape orientation. (spacing issues) If I run the racking vertical I can get the minimum spacing for the panels of 13" down the long...
