Hi

@jumper, but you shared with me this link and it shows 

https://community.victronenergy.com/questions/125321/taico-bms-not-detecting-by-ccgx.html

and they said they used Victorn and Pylontech from voltronic with CAN and it works.

I asked Taico and they said it works.

@coloumb: is saying that it should be RG485. 
 

I need a solid answer, did anyone try the same setup like my setup

3 inverter Axperts king 2 with 4 Taico batteries or not?

i need a solid solution  to solve my issue, trying and trying, no one is telling something solid.

do I need Firmware?

do i need RG485 or CAN?

do I need Poly, LIB or other from inver?

do I need Victron, Darfon or any other setting from Taico?

why Taico does not test such setup at their end and close the story?!!!!!

 

Who can decide the protocol CAN or RG485, the Battery or the inverter as the cable that I did support both connection types!?

from battery it seems there is an option to select communication type?! Is this right?

why terminator at battery with CAN? Is this must or optional?

That is a victron forum, the people there are working with victron inverters. I linked there to show that they have the battery comms working and they have the bms software working too. I thought you were using CAN and so are they so I was demonstrating that it does work (on a different inverter). There is also info there showing the different settings for the CAN protocols on the bms... it was just for reference, not direct wiring for the axpert.

I'm not sure you will find someone on here with the exact same setup as you have, that's why I was trying to assist you.

Btw there is another user on here with a different battery, but looks like the same bms and they were given different dip settings by their supplier, maybe you want to have a look. They have a different inverter too, but I'm just trying to find info for you on what actually works regarding parallel wiring and dip settings:

Hopefully you can find someone who has your battery and inverter combo.

Just to conclude on the settings I've been told, with 2 batts of the same brand and spec: "master batt": dip switches 1-4 off. Slave batt: 1 ON 2,3,4 off. I have yet to test extensively wether these are the correct settings, but its what I've been told, so take it with a grain of salt.

Hi 

what is the right DIP switches for my 4 TAICO batteries.

Master DIP switch?

Slave1 dip switch?

Slave2 dip switch?

Slave4 dip switch?

so I can see in master inverter 800AH and 40960Watt batteries capacity.

Axpert king 2 only show the value  like 

P04 or p01 and Group!!! do we have a way to see the 4 batteries capacity with Axpert king 2 inverter/.

Hi all! We have an Axpert max II8000 inverter and Pylontech US2000C batteries. To connect the inverter to the battery, you need to use a cable that is suitable for Victron inverters. On the cable from the side of the inverter we use pins 7-8, on the battery we use pins 3-5. You should get inv->bat : 3-8, 5-7. On the Inverter, in the BMS connector, on the battery, in the 485 connector. On the main battery (master), turn on DIP 1. Sorry for my English .

For cable, I did the right one.

Now on the battery side, when you use pylontech. in the BMS of the battery what you choose, you choose Victron or another type of inverters.

because in my Taico monitor software, I should be selecting the type of inverter to talk to Axpert.

for example: if you choose LIB in Axpert

I works with RG485 and Daifon on Taico battery

now you are saying Pylontech

what should I use in Battery side as

victron or what.

how many batteries you have?

which dip switch on master u use?

0 0 0 0 or 1 0 0 0 ?

What i should choose

for Victron it is CAN

for Daifon RG485

this is a Taico BMS monitor, what you choosed in your case?

In your picture there is mistake, from batery should be 3 5 for RG485 and from inverter should be 7 and 8

 

in my case / yes 3 5 from inverter it is 67.

what is the dip switch you make in the master battery?

Ты прав! Извините за булавки, ваша картинка правильная?

I made the cable for this inverter and battery as recommended by the equipment supplier. And it so happened that in this case the cable is compatible with the Victron inverter. I just connected the inverter and battery. Set the battery type through the inverter menu. All!

Now it seems from my side

for RG485

i used from inverter 3 5 

and from battery 1 2

now for Pylontech? 
do you have battery software to configure? What did you select

RG485

then which inverter type?

In my case it is not like this easy

it is giving fault 04 when I choose like this

i should select the right inverter from battery tool during setup.

The problem in mycase is the charging current when i select LIb type in inverter Is low and BMs is ok

i need to fix this by changing the type of battery and see, but how and what i should from battery setting

No, there is no battery software, I am a hardware installer. I can only change the software for the inverter. Otherwise, you can turn the battery into a brick, expensive brick

Can you help me with 

axpert king 2 voltronic inverter software 

do you have any new firmware which could help in charging current to be maximum while we have LIB type of battery selected as BMS is working fine however, current is limited to 30amp at inverter

also I have three inverter in parallel KIT mode, one of them is master

Можете ли вы помочь мне с 

Программное обеспечение инвертора Axpert King 2 Voltronic

также у меня есть три инвертора в параллельном режиме KIT, один из них является ведущим

Sorry, unfortunately I can’t help with the software, I don’t have much experience and I’m afraid to do harm))) Dear Coulomb knows better in this matter. If you have several inverters working in parallel mode, set the main inverter to the battery type, for example PYL, set the other batteries to USER settings with the necessary parameters for the batteries (voltage, current, etc.) and everything should work.

Problem is the battery BMS, battery is Taico using maybe like Pylontech BMS

what setting under battery should I choose from battery Monitor

with Victron inverter it is OK.

but with Axpert seems not.

do you know anyone tested Taico with Axpert inverters?

 What dip switches? According to expert catalog  the battery address is for group and not for battery pack

for instance if Dip 0000 means first group and master battery.

others not restricted.

If RS485-1 port

The inverter's display firmware decides that. Pylontechs will talk to whatever is plugged in to the appropriate port, RS-485 or CAN bus.

The inverter's display firmware decides because it only provides one option, the battery provides both.

From a slightly different perspective. I also have a King II in parallel mode. The maximum current is set by the BMS at 90 A (this can be set in the Seplos BMS). The problem is that when any solar power is available, the inverter does not charge from the grid unless I disconnect the solar string (or night ). It is normal? I have SLB UCB set primarily, but it doesn't work even in the second configuration that supports external charging. Otherwise SBU mode. Thank you

 

* 3.5 kW from PV and about 63 A to battery (31.5 A to 1st batt and 31.5 A to 2nd batt)

Yes it is normal if there is any PV coming in even at a low 10V and very low current the inverter does see PV is available and it will only switch to grid charging if there is no PV. I  even find at 19h00 the inverter will switch to grid and back to PV a number of times before staying on grid charge.

That's weird. I would expect it to be waiting for start-up voltage under these conditions. The Max manuals mention a start-up voltage of 80±5 V. Oddly, the King II manual doesn't mention a start-up voltage. Though we do see weird readings on the Maxs in the early morning too, followed by a period of supposedly zero volts.

I assume that you get a mild form of "stuck at 120 V" in the morning and evening; the MPPT code looks identical to that of the MAXs, except that the King II's minimum MPPT voltage is 120 V (compared with 90 V for the Maxs).

Hi Guys!

 

I have an axpert max 8kw with taico batteries 3 pcs 51.2v/100ah but when I connected them the axpert says low voltage “code 4”. The batteries are almost full. Any idea to solve this problem? The batteries see each other and the inverter works in lib mode. 
 

thanks

What battery voltage does the inverter report? 

What does a multimeter read?

My wild guess: the inrush current is too high and the BMS disconnects. You could try pre-charging the battery capacitors. Discussion here:

https://forums.aeva.asn.au/viewtopic.php?p=97722#p97722

My batteries are Junlee brand, but use same BMS . There is an option in the BMS that Taico uses - current limiting. And if it's checked as ON, the BMS will not allow to charge more than certain amps in that setting. In my case - 10A. Inverter tries to push 60A, as I have 3 batteries In parallel. But as soon as I put batteries in Darfon, RS485 and inverter into the LIB - inverter switches to SUB mode, and shows "warning 60" - battery is not allowed to charge or discharge. Manual for the BMS says, that with this option on BMS checks the incoming current every 10min. and if it's higher then indicated in setting "limiting current", BMS goes to the sleep mode. 
Regarding the RS485 A-B ports - in my case A to B made parallel connection, and I see both batteries in parallel monitoring in RS232 monitoring software.
Also the strange thing that when BMS connected to the inverter, in the WatchPower it shows the back to charge and back to discharge voltage, but settings back to charge % and back to discharge % is 0. And it's not possible to adjust that.
My idea is switching off the current limiting option might help to fix the low charge current issue. Didn't try that yet though to be sure. By the way, I had pretty good communication with the Taico representative in Whatsup via +86 176 8854 3176.  She was responding pretty fast with some recommendations. So it might be good idea for Ibrahim to write to her with his issue.
