I don't think you have enough battery for a 12000T, I have 2 Growatt, 6000T and 12000T. At first the 6000T was on 2 LifePower4 batteries and would fault when starting a heavy load, added another battery and no more problems. currently have 4 Lifepower4 on that system and starts 1.5 HP well pump...

I noticed when I used the "calibration" tool the display battery voltage on the Growatt changed, 51.2 makes no sense at all. setting to 51.2 and error 61 came back. I then hooked laptop to the batteries and set the calibration to the current voltage (with solar input off and MPPT not charging)...

Hmm, was the software different than that is available on this forum?

My 6000T doesn't hit 100% most times, not sure why the growatt has battery coms with EG4 lifepower. your lead acid is not communicating with inverter and must look at voltage. what does battery voltage look like at end of day? my solar backs off as battery fills, and here battery is at 99% by...

I had the same code on SPF 6000T during a cloudy couple of days, batteries (EG4 lifepower) were at 31% and indicated 52.1volts. my output was reduced to 229 also code 4 went away next day when the sun came out. no com issue fault code was present. perhaps output power was reduced to conserve...

bummer, try power down everthing for short time and see if it will reboot. I have seen several others disconnet batterys and complete power down unit for a while and then restart successfully

Static water level is 140' pump is at 480' about 20' additional head to top of 3000 gal tank

is that the spf 6000T?

did you disconnect battery and power down for 30 minutes?

you are correct, wrong link. correct link here: https://www.amazon.com/Victron-Energy-VE-Direct-USB-Cable/dp/B01LZ6WTLW/ref=sr_1_1?crid=25KO0AAMKQRH0&keywords=victron+ve.direct+cable&qid=1674613329&s=electronics&sprefix=victron+%2Celectronics%2C260&sr=1-1

Hopefully it will come back up tomorrow, I am using Lifep04, but I see there is a setting for FLd not sure if that will help you. USE would work if you set the other parameters as needed. I used FLA batteries for 20 years, Crown and Trojans, best thing I ever did was buy Lifep04 no more battery...

Not sure where the Growatt is getting a battery percentage from. Voltage looks ok for lead acid. Is there any absorbing time? The lead acid needs that to get fully charged, you should review Crown charging spec and make sure your charging profile is correct for the lead acid.

lost another 0.1 % less then 3 weeks between drop

Hello Danny, that is unfortunate The firmware didn't help you. I see based on your log screenshot you receiving data glitches similar to what I get on my 6000T, I understand you're connected via USB directly to the inverter? I'm receiving the same glitches using shine Wi-Fi dongle. Were you able...

Data glitches

yeah sorry for incorrect link, I had the old laptop so 0$ and 29$ for ve.direct to usb, wifi covers my garage 200 ft and I'm able to see victron connect app from anywhere along with other interesting stuff in the garage:

Hi Browse, Yup, I agree. I have a Trace SW4048 has been running for almost 20 years 7/24 hard to argue with that but the price to upgrade to a Radian from Outback is much higher than Growatt. but you get what you pay for I guess....

if the OP does not have an old windows machine the mini-PC like you have is also a good route and victronconnect app will not see shunt via BT, 29 $ for VE.Direct to USB was reasonable to me

No I haven't adjusted for error 61 yet, the win 7 laptop battery is shot and will require more work to drag over to the site. Also watching Aymanhammoud experience to decide if I want to attempt, or upgrade to another AIO. The 6000t is running with error 61 so not sure...

I have not noticed SOC over 100%, I will observe today and see where it ends up

Hello @SparkyJJO Just wondering if you were able to see the part number for the resistor R19? My 8048 has the same issue and I was able to look at a 4048A power board to see R19 on that board is a 2210, not sure if I want to proceed based on that info but hey, the 8048 is not working now so...

Hello Brightside, thanks for picture. I was able to order 221 ohm resister and installed at R19. However, no love. when I energized the 8048 R19 heated up,smoked and the solder melted dropping the resister of the board so I'm guessing there is more to the Radian R19 story than I want to follow...

Chris, how are you adjusting charge current?

I'm not losing sleep over SOH from these, just makes me wonder why the difference? my packs get charged to balance voltage most every day (setting on SCC is 55.6 to absorb) that pack is usually less than 0.01 delta at full charge edit: currently 0.027 delta during balance

Link to software for calibrating for error 61 is in message number 66 of this thread from Danny

I have done this in the past with two hondas, 3500 and 3000 watt units. pretty much for the same reason as you :)

Currently full and balancing, SOC on all 4 batteries at 100%

Hello Tim, is your comment referring to my 6000T well pumping? I havent had any battery issues: 3 EG4 lifepower seem to be adequate for my demand, never was intended to run more than 1 pump at a time
