    MPP PIP2724 versus EG4 3kw

    Have the Growatt in my campervan and don't hear the noise much until the fans kick on with the inverter on.... kicks on high when I'm running the microwave, a drill etc at higher amperage.... kicks off when done, so I really don't notice it... especially with just the monitor/speakers on with...

    Growatt + Daly, constant pain

    I can't remember exactly what Ian said about it, but you're probably right on the 'non-smart' BMS that I had, as the 'smart' ones can be programmed better around the needs of the GW. I just know he was right.... first, as a newbie, I had the basic issues, but my 'non-smart' non-programmable BMS...

    Growatt + Daly, constant pain

    Yes, I have repeatedly check the individual cells... one of mine charges up faster than the other 7... not really a problem if I set the charge lower... currently have it set at 27.5, so the GW always shuts off about .1 above that, as the reading goes up and down some while charging, which could...

    Growatt 3000 24 volt shutting down.

    Yeah, I think most everyone does the 'user defined' setting. I'm in a campervan with excess panels and battery for my needs, so only problem I had was the BMS as Ian mentions over and over... seems most of them give the GW a problem... so I don't use one any more... haven't needed the alt to...

    Growatt + Daly, constant pain

    Ion at GW explained to me that the BMS's we use is the biggest problem.... I finally agreed after frying mine.... the GW doesn't seem to need it... I have them inside the vacampervan setup)... same batteries in self build.... all new to me.... GW worked fine without the BMS... I have one cell...

    Growatt3000 24v with Daly100A BMS unit settings and issues.

    No, don't trust the ISDT much, especially after I put multiple extensions on it... which really didn't change much, but I have another meter to check the loads and general battery charge etc... but I mostly trust the multimeter for battery cell charge; that said, they are all consistent in their...

    Growatt3000 24v with Daly100A BMS unit settings and issues.

    Was that qoute a question? M problem was the BMS... shorted out a terminal connection on the first one, installed the wrong BMS the second time... didnt notice that short until I put it back on after returning the second BMS... in the end, I'm not using a BMS.... since I have plenty of solar for...

    MPP 1012 voltage bouncing around?

    My Growatt had a similar issue, ended up being the BMS. When I disconnected the BMS, the fluctuations went away. One of the leads going into the BMS was shorted out... another BMS was the wrong type... no problem once I top balanced and took the BMS off. That shorted out lead was the connection...

    Gw 3000tl lv user2 setting

    Yes, I've read that lithiums don't need or even want to 'float'... I do know that the other little lithium batteries in home appliances, like shavers etc, are usually used till near zero.. and then recharged to 100%. So, after playing around with it.. due to my screwing the BMS up initially...

    Gw 3000tl lv user2 setting

    Did you ask Ian about this? When I asked, that setting for USER2 does link Prog 19 and 20... I setup my system for double my current usage, so I really don't need it to charge up everyday unless a storm system is overhead for a few days. I find that during charging, the reading on the GW is...

    Ok, 18650 is Li-Ion? Doesn't it say LiFePO4 in that ad on Amazon? ... didn't arrive with any temp probe either... not a separate one, unless it uses the cell wires for analysis? That ad says: DALY BMS 8S 24V 200A LiFePO4 Battery Protection Module PCB Protection Board with Balance Leads Wires...

    Growatt3000 24v with Daly100A BMS unit settings and issues.

    Tried running the wire to the GW thru the meter shunt.... doesn't seem to be a problem... just ~.1v loss. This was just after 5pm with the solar panels in the shade about 80v, 0amps, 36 watts. Meter Shunt-- 26.68v Growatt--------26.76v Battery---------26.70v Turned inverter on a little later...

    Growatt3000 24v with Daly100A BMS unit settings and issues.

    GW without BMS charging fine, at 27.1v on GW monitor, 26.68 on battery ISDT meter. One thing when testing the BMS that I didn't think of is that I have a different battery meter's shunt between the out wire for the BMS to the GW. Could this be the problem? I think I'll test it later if the...

    Growatt3000 24v with Daly100A BMS unit settings and issues.

    Well, after cleaning, that cell doesn't "run" anymore... it's normal, and the same with the last #8 cell, only off ~.01v so not a problem, right? as it doesn't "run" either... all stable off the Daly BMS. So, I reattached the BMS this morning and back to the same problem of the fluctuating batt...

    Growatt3000 24v with Daly100A BMS unit settings and issues.

    Hey Zwy, I did as Ian suggested, disconnected the BMS and it works... fine except that bad cell ... so I read up on this problem here and cleaning the busbars etc was the first move and WTF! Seems that was it.... on the main #5 cell , tested inverter... seems ok... in the shade now, and I'll...

    Growatt3000 24v with Daly100A BMS unit settings and issues.

    Charging seems fine EXCEPT for one bad cell in the battery, that charges ~.5v faster/higher and discharges ~.7v faster with inverter on... Didn't notice this before, but I didn't watch the individual cell readings enough to notice. Not sure how much of this is causing the other issue with the...

    Growatt3000 24v with Daly100A BMS unit settings and issues.

    Well, like I said, the firmware update got rid of the beep, the program stays in 'off' mode, though the symbol remains on screen. I've tried all the connections, another Daly BMS, and as Ian said, it's the BMS going into 'open circuit' mode, if that term is correct, as I really don't understand...

    Growatt3000 24v with Daly100A BMS unit settings and issues.

    Well, after the firmware update, which helped... finally got rid of the beep, even if the icon remains on screen, but the US2 has to be used for LifePo and there is only one setting for bulk/absorption, no bulk, then absorb, changing one automatically changes the other, which isn't a problem...

    3 CSUN 310w mono panels... 60 cell... VOC is 40.0v I set them up on the roof of the van in parallel mode because half the day is under a tree, even though it doesn't have leaves on it yet, and I think I'll send more time in those conditions than out in the open desert sun which is better for...

    Growatt3000 24v with Daly100A BMS unit settings and issues.

    Yeah, I'm on SBU, just trying anything to see what happens... so far, nothing much... same result tonight. I did notice the charging went higher today... 29.8- 29.9 at times... even though the Bulk setting is 28.8.. and the float 28.2... maybe that did something? Low cut off still set at 21.4v...

    Growatt3000 24v with Daly100A BMS unit settings and issues.

    Made it out early this morning to the campervan (off grid setup).... similar but different, unit was off, no backlit screen... before sunrise.... then unit came on and fans started the same cycle... couple seconds on, then off and alarm beeps... the alarm symbol shows up on screen... then about...

    Growatt3000 24v with Daly100A BMS unit settings and issues.

    For Program #21, Low Volt Cutoff, the setting is 21.4.... the battery cells are listed as 2.5/cell, so 20, so I put 21.4 for low volt cutoff. As for the BMS, I just put a new Daly BMS on it.... had problems with previous Daly... this one is just a little larger... common port 24v 200a/100a DL8S...

    Growatt3000 24v with Daly100A BMS unit settings and issues.

    Yes... seems to be working after another issue with the BMS... so now, it seems a matter of tweaking the settings as Ian said.... Understanding them would come first, but it is shutting off and on regularly.. OSIS.... I was a little late checking it last night and this morning, but before it...

    Growatt3000 24v with Daly100A BMS unit settings and issues.

    Ok, thanks a lot.... this is in a campervan setup. I can try one at a time, but that means doing so every 15 minutes after sunset and before twilight, so it will take some time. I don't have any utility plugged in, so your mention of it trying to switch back and forth as the solar goes flat...

    Growatt3000 24v with Daly100A BMS unit settings and issues.

    Ok, no change... Ian said I didn't need the firmware, just reset,.... must be one of my settings. So... what any ideas? As for the settings, I tried SOL and SBU... the change did nothing. What is the difference really? They sound the same in the booklet. My problem is that 15 minutes before...

    Hopefully getting my van back today to do this firmware update, then I see this comment by Ian on another thread with the beeping problem: (1) Growatt spf 3000TL LVM -24p....change program 15 to BOF but it still beeps. Is it abnormal?? | DIY Solar Power Forum Seems maybe I should wait awhile...

    Growatt spf 3000TL LVM -24p....change program 15 to BOF but it still beeps. Is it abnormal??

    On my thread on the Growatt, was posted an updated version of the prgramming for it, mentioning a update from last July 2020.... but comments below the video on YT from 3 weeks ago, said to turn Program 15 'On', not off, as that worked to shut it off for them: GroWatt SPF3000TL LVM-48p Secrets...

    Thanks, didn't know he put out a new update video.... but the comments still complain of the beeping not going away. So, I need to update the firmware so USER2 shows up for Program 5 as it seems they did an update last year after I bought it. I wonder if this matters as others are still...

    Growatt3000 24v with Daly100A BMS unit settings and issues.

    Changing Program 1 to Sbu didn't work, same problem after sunset, the 15 minutes leading up to twilight t be exact. And the beeping remains... seems to stay in 'off' mode until this approach to twilight every night.

    Growatt3000 24v with Daly100A BMS unit settings and issues.

    Ok... I'm back... BMS issue resolved, but the Growatt3000 24v unit is in Solar First mode and at sunset, it goes into a 15 minute routine every night in which every 30 seconds the fans turn on for 2 seconds, then shut off and the beep alarm goes on for 3 seconds... until the sunlight is dark...

    COmmon port model.... but I found the problem is a wire short on one of the leads... I bent it and it started working again, back to 26v. So, I'll have to fix that lead... works now after I bent it back up a little, but I'll have to replace it for long term. It seems that moving the cover off...

    New day, same problem... checked the reading out of the Daly BMS this morning and only 15.83v..... tried the shorting process again of B_ to P- and it went to 22.27 without the balance harness connected... still 15.83 connected.... same as yesterday... either way, just sitting overnight without...
