bms-to-inverter's Introduction

BMS to Solar Inverter communication

(Use, monitor and control any battery brand with any inverter)

This application is reading data from a BMS and sending it to an inverter. This way you have no restriction on what battery brands you can use with your inverter. Many inverter manufacturers only allow batteries from certain battery manufacturers and certain models. This project enables you to read your BMS's data via different protocols - RS485, RS232, UART, ModBus or CAN - and write the battery data to the inverter in a specification that the inverter supports - Pylontech, SMA, Growatt, Deye, SolArk, etc. You can monitor each of your battery packs cells and view alarm states on the included webserver or hook up via the MQTT broker on your smart home. Or you can just read out your BMS's data and use the optional MQTT broker or Webserver to monitor your batteries packs and cells wherever you are.

The (reference) project uses a Raspberry Pi 4B with a Waveshare RS485/CAN hat or Waveshare 2-Channel CAN FD HAT module but you can use any CAN or RS485 module for your PI that provides ports like can0 or /dev/ttyS0 or similar. It will also work on older/newer PI's such as 3 or 5. The appplication supports multiple BMS (even mixes from different manufacturers), aggregating them and sending the data to the configurable inverter.

This way you control what gets send to the inverter.

A wide range of BMS and inverters already supported (see below). Any BMS or inverter can be supported in a very short time by just mapping the manufacturers protocol specification in an own implementation of the BMS or Inverter.

NOTE: If you would like me to add a BMS or inverter module just let me know! I would appreciate support to test the BMS and inverter bindings in all variations. Please let me know if you would like to support this project - Testers are very welcome! :)

bms-to-inverter's Issues

Webserver module

I noticed a bug that after sometime 24 hours the webserver is working but do not refresh values like SoC and other correctly. Actually they stay as they were previous day. App seems to work no crash. I stop and start it and everything is displayed normal updated. If you need more info you can email me for live access.

Daly BMS - ttl

Hello,
Currently you are supporting Daly BMS (RS485 or CAN).
I have bad luck with my daly bms and i am missing the hardware parts in my Daly for CAN/RS485.
I have only TTL usb.

Maybe i should use USB to RS-485 but how i am gonna connect it to my PI ? Now i can connect directly via USB
and read data like cells , soc and all of this.

Batteries with no content shown in the overview and webserver

When using Pylon HV BMS with non-incremental identifiers for batteries there are batteries shown
with no content in the overview and webserver.

First time running with Daly TTL

Here is the debug info as requested:

root@sol:~/test # java -jar bms-to-inverter-main-0.0.1-SNAPSHOT.jar

debug.txt

also I am attaching my pom.xml and config.properties files

Raspberry Pi 5 compatibility

Not really important to fix since Pi 4's are still easily obtainable.
It might be worthwhile putting a warning that the Pi 5 and Waveshare RS485/CAN adapter may (probably) not work and still a work in progress.

Just in case anyone (like me :) ) think to get a Pi 5 because it's the newest.

Growatt Hybrid high voltage / Pylontech BMS high voltage (powercube x1) / CAN

Hi,
great work. Thx.
A quick question, support your converter the Growatt SPH Hybrid (HV) series and the Pylontech HV BMS system (powercube X1) over CAN?
Thanks for your response.
Best regards
Utz

configuration issues

After latest commits seems like webserver and email is broken. Also there are many errors in cleanrepo.sh

Hardware connection to the Growatt Inverter

Hello,
I have little technical question about connecting Growatt to PI.
I have 3 ways to connect it. One is via RS-485 to USB but as i see you started only CAN. Next way is connecting via CAN from the inverter to USB port in the PI device. Growatt has one USB port too which i have already once connected to my PI for reading inverter data. Now i am wondering how exactly to connect it to the inverter. I have received CAN to USB modules so i can use that too. Also i think growatt has some kind of password which is growatt+current_date. Can you give a little help how exactly you are expecting the data from the inverter via CAN ?

mqtt with authentication?

Hello,

is there any way to use mqtt with authentication?

I was trying tcp://login:password@server_ip:1883 but no luck
mosquitto reports in logs:
Client disconnected due to protocol error.

cheers

Growatt Inverter support via RS 485 / CAN

Hello,
Do you plan any support for Growatt Inverter support via RS 485 ?

waveshare CAN expansion hat compatibility

Does it also work with the Waveshare 2-Channel Isolated Can Expansion Hat or does it only work with the flexible data rate (FD) version ?

Nice project by the way.

Daly Growatt implementation imminent

Hiya

16 Lishen 272ah @ 1C
Daly 48v 150A
Growatt SPF 5000ES
Solar only, generator backup

No comms to BMS

RS485 (Daly) to RJ45 (growatt) fail. Crimped then inverted pins then removed 2 then inverted again. Could not set BMS to any specific (Pylon) protocol. Speedy email response from Daly support asked where I bought it but hasn't replied to me since I told them it was a small south African online shop that has since closed down, with a very bad reputation.

Daly interface board option but I think I still need to set the battery type on BMS so I don't want to buy it.

RS485 (Daly) to USB windows success
Daly software could also not change battery protocol. But I had full live Conn to BMS, all voltages etc working fine. 3 wire from RS485 to USB. So the BMS is speaking fine. Just need to relay the message.

Tomorrow I'm going to get my first ever Pi. Pi 3 and with your suggested IO. Then I'll follow your guide as best that I can. I'm excited.

I need this. My growatt isn't very good at charging blindly. 😅
