I did it just as you described. I built a switch between the two generators and put 240 volt incandescent light across the switch, adjusted speed till phase matched and closed the switch. then feed the load. the two generators ran fine

1. Growatt SPF 12000T DVM MPV, low frequency inverter 2. 120/240 vac pure sine wave, split phase 3. 12 Kw 4. Idle/no load: 133 watts, measured 2.55 A @ 52.3 V Spec: none published 5. No power-save/search mode in use, I'm always at least 500 watts

I have Victron smart shunt in the garage 200 feet away connected via VE.bus to USB...

Watch for multiwire branch circuits, you would be powering both legs from one phase and potentially overload the neutral

here is the power supply I use to balance: any similar would work link to Amazon: https://a.co/d/dQqSJAF

Hello Jungblud59, I just completed setup of SPF 6000T DVM MPV for a friend on 10 acre property for an irrigation system. loads are a 1.5 HP deep well, a 1.5 HP pressure, and a 1 HP pressure pumps. pressure pumps are controlled via irrigation timers to run separately, well pump is on timer to...

google "edge of cloud effect"

Ok looks like you can sit at 55v keep it there for as long as you can stand. correct Current doesnt "need" to be flowing. correct The only thing that matters is that the balancing is working. THIS! Does it balance without charging? Or does it stop as soon as its in float? Balance will continue...

If you are in US set hz to 60, I have the 6000t and if I was going to purchase again I would go larger maybe even 12k

Hi John, each battery has a unique address set via dip switch and are then daisy chain together with short cat5 cables. laptop running BMS test software is connected and reads all battery data, up to 16 batteries

Hello, fight thepower I have an irrigation system consisting of three pumps. Two pressure pumps 1.5 and one horsepower and a deep well at 1.5 hp Growatt SPF 6000T with 3x EG4 batteries and 5kw solar will run any combination of two pumps but not the third. The system pumps about 1500 gallons of...

I tested the 6000t and it shut down with overload at 3200 watts on one phase, after approximately 10 seconds

I am running the 10gs15, pump starts at approximately 13 gpm and 2200 watts and tapering to rated flow of 10. Gpm at about 1850 watts. Pump goes to gravity storage so no pressure head, I would guess about 10kw starting power. 6000t has no problem with that.

JLB, I will keep this thread updated, I also have two more packs to be added when I get a rack set up. I will update SOH on all 6 at that time. bruce

Well, you can leave the setting as adjusted by SigSolar and cells will eventually balance. (You will be bald by then) lowering the current will not slow the charge as the runner cells will over voltage protect (OVP) because even 2 amps at 56.4 V will push runner cells up, lower charge voltage...

Hey Danny, Thanks for the update, glad you are at full power. ? Too bad you had to deal with faulty equipment. Took a lot of nerve to continue with Growatt after that

As ScrousGB said, you need to see delta while charging at 3.48/cell and above. your cells are way out of balance and need to be held at balance voltage but below protection voltage for some time. The BMS in the Lifepower4 pack does not have much balance current, it took me a week of charging...

firmware on his batteries start balance at 3.45 and continue to balance high cells till all cells fall below 3.45, password protected parameters not sure if EG4 will give up the password

bummer, past my experience. hopefully watts24/7 or signature solar will help. unfortunate a firmware update gets you here. good luck! thanks for the update, I will continue to follow...

Danny, No worries, bummer to have to ship unit back. My 6000T still has error 61 but is performing well, pumping water. I will report back when/if I get the "calibration tool" to work. Good Luck with the 12K I will watch your results as that was going to be my next purchase for the house end of...

what do you have setting 05 set to?

so on the 6000XP you are adjusting current at setting #6? or in monitor.eg4electronics.com at maintenance tab for charge settings, what is the "charge voltage (V)" right below "charge current limit(Adc) set to? this is where you can set voltage to stop from hitting "overvoltage protection" if...

I use two bench power suppy as I linked in #42, one set to pack voltage (start at 55V) and one I rotate to the low cells till all cells are at 3.550 then I let the BMS do its job, I can get a pack balance in 24 hours, I think thats a better invesment than a chargverter

Hello Danny, I'm glad your new 12K is working for you would be interesting to hear from signature solar what was going on with the other one, at this time I have not been able to get over to the 6000T with a Windows 7 machine I'll post back to this thread when I do with the results on error 61

how are you charging? solar? or? 47 volts sounds good, should not disconnect at 50 v. my 6000T did not disconect with code 4, however I need to perform a calibration still to stop code 61

good luck in the AM, please update on status

Unfortunately it only shows at most the past 24 hours unless I export data. funny the grass is always greener over the other side (Batrium)

Cory has been most helpful with some issues i have had on SPF 12000K DVM MPV, have you tried logging in to the web portal? http://server-us.growatt.com/login what tim said about shine app is true for me also

That is a great question, I have purchased 14 of the Lifepower batteries. installed at 3 different locations. I will have to research that aspect to see what went where. I will follow up with that next time I visit the remote locations, 6 batteries are located at my house others are at two...

I have SA as well, just use the growatt site for info as you are correct on lack of configuration, loads just fine for me on mobile or desktop however SA much better

I have 4 of the EG4 lifepower and here is my observation over the last year: notice the different cycle count, two different purchases of 3 and 1 batteries. I am watching the 63 cycle battery drop 0.1 % every month. It was at 99.7 SOH when I put it in service. I would be happy to see 0.3 over...

Danny I just got the warning code 61 on 5/28, three-day weekend-right? so I'll see what tech @SignatureSolar has to say soon I hope. I'm running well pump and 2 pressure pump off the 6000T and it has no problem with one at a time so is somewhat of a balancing act to get them timed right, has...

Like Scrotus said, set the voltage and leave it for several days, balance current on these BMS is weak. you might be able to move up 0.1 volt every other day once you get the delta down in the 0.030 - 0.020 V range but until then nothing you can change will help. goal is to have balance on and...

CV setting on the 6000XP is too high (default is 56.4), I would leave it on lead and drop CV setting (#7) down till you don't get overvoltage protection and allow BMS to balance until cell deltas get lower, whats up with pack 1 total voltage is 1 volt less than the other 3?

SOC will be way out of wack till you get the cell delta down, I have 14 of the lifep04, in three batches, I just open them up and balance manually, all 14 are at 0.007 - 0.009 delta at 55.4 volts where I stop CV

BMS does not need current to balance, passive balancer will bleed off current from the high cells, thats all that is happening I'm not sure how much balance current these BMS have but do some math, if the high cell is 5 ah (5000 mAh) fuller than the low cell and BMS is maybe 150 mA - 5000/150...

Very nice, hope to get ya back up soon. Bummer that firmware upgrade bricks the control board. I will not be upgrading my firmware any time soon...

This was at end of the charge? cell delta at 53 volts is easy to get down, what is delta at 55 pack voltage? you are charging with a chargeverter? the cell voltage has to get high enuf to hit balance

Danny however with 12K and 400ah.......

Just sold my 2014 spark to upgrade to 2023 bolt. 45K solar powered miles and not one issue on the Spark 83 mile range when new was delivering 75 +/- miles when I sold it. might be kinda hard to find in NC since was a compliance car here in CA. effectively paid $11500 for the Spark after tax...

I do not use the server for settings as the language is different for many parameters, I set all parameters at the local device and step through the user manual that came with each device, do you have the user manuals? available here...

few people have been successful using newer OS, I haven't tried with win 7 yet, and failed to connect with win 10.

Hello Danny1987, I have the SPF 6000T DVM MPV version and have had it in service for just 10 days. Now receiving the same fault/warning code 61 as you are but not seeing any voltage swings. I have sent an email to tech@signaturesolar.com as Alex suggested above, however, I wondered if you had an...

ok thanks

I had the same problem with FM 80, sent it into Outback and refurbed/repaired for flat rate of 90$

I also have two Growatt, SPF 6000T and SPF 12000T I changed all settings locally when I powered up both units. I only use the Growatt server to monitor, The manual has a list of parameters and default settings, I believe a password is needed to change the setting via the server, and is kinda...

Good deal, so you were able to use a win 10 machine and recalibrate the inverter to clear error 61?

Where are you getting your data from? Growatt Shine app? I am running SPF 6000t and using Shine app, my data is all over the place, only thing I believe is SOC. Maybe some time weighted average will give you more insight.

Update on error 61: was able to calibrate with win 7 laptop. Will continue to monitor system.
