Deye SUN-8K-SG02LP3-EU works with Seplos BMS v2 (10E)

[MSXGames]

Hi All,

If this question is already asked or there is a threath, please forgive me.

But my question is as followed
I have 2 battery kits with each a Seplos BMS v2 (10E), with 16 cells
I am thinking of buying the Deye sun-8k-sg04lp3-eu and connect the Seplos battery kits to it.

The thing that I want to know is, does the Deye inverter works with the Seplos BMS v2 (10E) ?

Does anyone have the settings for it ?

Thank you
Kind regards

Yes, it should work. Set Deye to Lithium 00 or 01, I can't remember.

will work perfectly , both on CANbus and RS485
( i run a variant of these inverters and seplos mason boxes and 10E bms)

btw love the username ;-) en welkom op het forum

Dank je wel voor de ontvangst

Then I have another question, the Deye inverter is working and is charger the battery, but when there is no solar, the Deye inverter will not use the batteries to power the house (battery discharge to power the inverter) and the inverter is using grid power for powering the house.
Is it possible that I forget a setting ?

How's you mode setting, "load first" or "battery first" ?
Have you setup Time of Use ?

 

[MSXGames]

Time of Use is on (grid or gen charge is off)
I have Zero Export To Load first (think this is the battery first, then load house, then grid)
I want to use Zero Export To CT (load house, battery, grid), but if I use this Zero Export To CT, it is beeping, I think because the ct-clamps are not installed yet, but there is a ct meter (chnt) installed.
The ct-clamps need to be on a specific place, but I am in doubt, before the circuit breaker and after the grid meter or after the circuit breaker and before the chnt meter.

Here are the pictures of the inverter settings for the battery.
If you need other pictures of the settings, let me know.

Hi All,

Here an update.
What I have found out (thanks to @houseofancients ), is that there are chint 3-phase meters with software from Growatt,
I had a Growatt inverter before and that comes with the chint meter, I thought that all chint meters are the same.
But in this case not, the chint that is delivered with the Growatt inverter will not work with the Deye inverter (pin layout differs).

So I bought a new chint meter and that works flawless with the Deye inverter.

Kind regards

The meter you bought is a generic one or specific to Deye?

 

[MSXGames]

Just a generic one, bought it from Amazon.
CHINT DTSU666

The eastrons work just as good

Eastron SDM230 modbus 1 fase kWh meter

Geavanceerde 1 fase kWh meter met een Modbus RS485 uitgang voor communicatie met randapparatuur. Daarnaast is deze kWh meter MID gekeurd voor officiële registraties en verrekeningen.

webshop.cedel.nl

Single phase modbus V2

For 3 phase installs ( and the one I have been running)

https://webshop.cedel.nl/nl/Eastron-SDM630-3-Fase-kWh-meter-Modbus

Both are for 230v
I am sure they have split phase ones too

Hello what protocol you use on seplos with deye sun? I have a problem to connection deye with seplos v2. Seplos have errors..

You can leave it default, it is set to pylontech on the BMS.
In the inverter, set to lithium, protocol 0 (pylontech)
Make sure you use the correct pinout on your network cable, as you most likely cannot use a straight cable ( depends on your model..)

What is the reason for an external energy meter? I don’t have one and my inverter reports and logs everything I’d expect it to: production, consumption, import and export.

Thank you. I haven’t found that. Yes, I asked the same question in a few different threads since not everyone reads every thread and this is a question that’s been on my mind for some time.

The responses I have seen to the question haven’t answered the question.

funzionerà perfettamente, sia su CANbus che su RS485
(io uso una variante di questi inverter e scatole Seplos Mason e BMS 10E)

comunque adoro il nome utente ;-) e benvenuto sul forum

SALVE IO NON RIESCO A COLLEGARE BMS SEPLOS V.20. VER 10 E IN RS485 CON INVERTER DEYE MONOFASE 6KW. QUALCUNO PUO DARMI DEI CONSIGLI ?

English would be better.
Why are you connecting through rs485 , and not the default for both deye and seplos v2 canbus ?
