2) My Shinephone app is no longer consistent, I find the device showing as offline a lot of the time. Is this a firmware issue linked with the change to using the BMS?

 

Discussed here I believe https://powerforum.co.za/topic/5535-growatt-data-missing/

 

Sorry been testing again ... 
So latest version of the firmware .. float works for the first maybe 4 hrs then falls .. So terminal voltage sinks . no good as it should at least retain the voltage . 

and inverter still takes its power from the battery when in standby ? pulling my hair out .

What does our friend to the East say?

Good day, Could you please email the firmware updates to me.

Thank you

 as you see it on battery backup applications no solar we have a problem .. and the charging symbol is gone never to return .. draining batteries in some cases till they are empty. Just did a test with old 4kw 48v mecer and dont have this issue . So its a problem with the firmware . pending resolve it will mean taking it up with the manufacture and supplier until either a change out for a model that does work or a firmware patch to fix the issue at hand ..

I'm a noob 👶 when it comes to Growatts; could you briefly summarise the difference between the ES and the TL-HVM, please?

as mentioned i think .. 450v dc mppt can handle 6500w of solar . has inbuilt power blending allowing grid to power devices and solar at the same time offsetting power consumption and batteryless operation meaning no battery mode .. headless mode lol . all of them work really well. also support canbus and rs485 . canbus works well and rs485 doesnt not sure why in my case . need to retest .

? So are these features common to both models, or to one? If so, which one?

By "charging symbol" do you mean the dotted lines pointing into the battery?

Or the "CC" in the bottom right corner?

Browsing the 500.07 firmware today, I see that the variable I'm calling chargeStage can only have three values, 1, 2, or 3, and in various commands these display as FC, CC, and CV respectively. I assume that these mean Float Charge, Constant Current, and Constant Voltage. So it's surprising to see the firmware apparently not charging at all. I suppose it's possible that this variable has been set to an invalid value somehow; if so, that's definitely a firmware bug.

Of course, there may be other variables that determine charge stage, I don't pretend to understand even 1% of the Growatt firmware as yet.

the 5000es model only not the 5000TL

So to highlight the three stages correctly this is actually what takes place .
CC 
Then CV
then FC 
if the systems remains in FC for too long the AC to DC charger symbol disappears and if you pull the plug and renable the power it enables the charg e process again .. and after the 2 or three hr window the symbol showing battery charge goes off the screen meaning no charge being applied at all to the battery . This is clearly a Firmware float bug issue . i Know i did question and send you a Pm about the issue regarding the Mecer/Axpert but it doesnt exist .. its true to the settings and holds its float well .
So this is  a Growatt issue . The higher model 5000es 450v MPPT doesnt do this. It holds and maintains float respectively .

So what main firmware version are you running?

If I understand the Growatt 5000W models correctly, there are:

SPF 5000TL HVM/HVM-P (it's unclear to me whether this is one model number or two): smaller display, 145 V max SCC. Parallelable up to 6 units. Perhaps the 5000TL HVM-P is the model number for a 5000TL HVM with a parallel card pre-installed.

SPF 5000TL-HVM-WPV: same as the above, except with a 450 V max SCC, and of course different firmware to support this.

SPF 5000 ES: similar specifications to the above, except that can handle up to 6000 W of PV, and it has the larger display (with 6 sets of numbers). This model may be an AC-coupled hybrid, where the inverter synchronises with the utility and pushes power into it, giving it the ability (if enabled) to export PV or battery power to the grid.

The subject of this topic is the first one.

How am I doing?

Hi there i have just gotten back to my desk i can take pics of the CC and CV and FC on the growatt 5000TL HVM and on the growatt 5000es with CC CV and FC if you would like ? though might be abit hard to emulate at this time of day with a 90% soc on my batteries but nothing is impossible . 
Im prepared to submit as much information as required to fix the bug seeing as growatt themselves seem to be head strong about the fact there is nothing wrong with their firmware... hmmm i wonder why that is ?

You are correct on all accounts in your post about SPF 5000TL-HVM-p with a parallel card seem to be the models we get here commonly and the spf 5000tl-HVM-WPV being 450v with a scc but doesnt support battery-less mode . 
5000ES i have installed and running and can fully access at present on solar but .. i dont have a firmware image for does the 6000w of solar and ac coupled hybrid indeed .  However being able to export power into the grid is yet to be confirmed .. would be a really nice feature to have actually .
let me know if you need pics ?

please see below

sorry not that is is not charging at all 
on use setting we get the CC and CV stages and even the FC stage.. meaning we bulk absorb and float .. but float only remains on for about between 2 and 4 hrs which is not great .. why should it turn off ?

Thank you

ive uploaded the firmware on my previous posts please can you get the firmware down from the attachments .. Note i hope im allowed admins ? i take no responsibility for the software and the effects, disclaimer use at your own peril !

Is there a changelog somewhere on exactly what the differences are between 500.07 and the 500.08 you attached?

maybe if we get a chinese man from growatt to explain but that might be hard .. i dont really know what changes have taken place .. the menus require real probing to get any idea of which selection to use for which battery type. The manual off their website is still version 1.0 . 1.2 seems to come out in the packaged more recent units but again no battery explaination for rs485 or canbus its all clouded in growatt mystery .. sorry

Ah, thanks.

I see that chargeStage has two more possible values now. There is EQ, and NU. EQ is very likely the equalisation stage, but any clues on what NU might be?

Has anyone seen NU in the corner of the display?

Edit: "Not Used" comes to mind, but that's just a wild guess.

Edit 2: NU stage is set in only one function, but that function gets called from 18 places.

ive done alot of testing and honestly have not seen this on the screen 
What we do know is that charge process now is flawed when using lithium batteries charges up to 100% then turns off solar totally .. runs of battery on the 5000TL version .
We know that the Float charge FC does not stay on and has a timer function built in that causes the unit to turn off float totally too .
Please advise all 18 places that it gets called from in the firmware code ? this might help me assist you with what it is used for ?

I am currently running AGM batteries and now, with loadshedding, I am in Utility first (line mode) most of the time to ensure my batteries are always fully charged. The inverter seems to keep the batteries in float all the time from the utility - but there are periodic breaks every night, mostly at around 1am for 40 min and then again at around 4am for about 15 min according to the data logs, where the inverter stops the float charge and starts it back up again. It seems timed and happens regularly, so it must be an intentional timer triggered function. Therefore this does not only happen with lithium profiles, also with AGM. I assume they must have a reason for it. Mine starts back up charging fine again, so it does not bother me at all, just thought I would mention it.

That's somewhat difficult to describe in words, and in many cases I simply don't know yet (it's an unknown function called from an unknown location, manipulating unknown areas of memory). In most cases however, it's about to change mode, 7 times to fault mode. There is a lot of clearing of memory at the same time, so I suspect it's part of "kill all charging". It's never called when changing to battery mode.

thanks for this update really helps alot .. 
confirm which firmware version and which battery setting are you using AGM ? FLA ? or USE ?
