G Thanks @georgelza , lol @Donovan_kk1997 My understanding/assumption is that most of the settings etc are managed on the "Master" inverter and there is very little that you need to change/setup on the "Slave" once they are connected. As a result I would guess that you would only need to connect to the Master Inverter to be able to change "Work Mode" settings, read production data etc as these are all read from the master inverter. It is however important to bear in mind that I have had no actual experience with a multi-Inverter setup and that this is all a guess and I could be totally wrong 🙂 I would start with one ESP32 or KellerZA connection and see what happens, worst case you have to get another one and try and work out how to set it up.

August 31, 20232 yr Hello Guys, @Sc00bs and @kellerza, Have you done any experimentation with communicating on the parallel ports? I have an interesting problem, using the REVOV R9 units with the TIAN POWER BMS modules which only have RS485 comms and thus if you want the inverters to connect to the BMS then you only have access to the Parallel ports or the RS232 port. At my house I am using Solar-assistant and the RS232 port but then cannot get inverter firmware updates or inverter status. I will message the guys at Solar-assistant and ask if the inverter status could be included in their MQTT messages. Would you recommend that I move over to the integration for Solarman? Does this now support changing of settings on the inverter? My parents house have the same batteries but with 2 x 12kw 3 phase inverters and the E-linter logger units, I do not want to use the E-linter to log data from the cloud and wanted a local solution. But require the E-linter units to remain connected as they have an SLA with the installer and the system is remote monitored. I also experienced some strange behaviour of not getting their BMS units to talk with the inverters on RS485 in the dual port. I have the Revov RCU v2 to convert the RS485 to CAN (you get very limited battery information on CAN), and then have Solar-assistant connecting on the RS485 portion of the dual purpose RJ54 BMS port. Their setup is further complicated by the inclusion of SolarEdge inverter providing feed on the aux input as a micro inverter. So getting all the data is quite a challenge. Solar-assistant say that both Sunsynk inverters need to have their own RS485 connection in order to get all the data. This does not really make much sense to me as all the data should be shared between inverters. Any input would be great.

It's only the settings/system mode controlled from the master.

You can write settings using the apps/web interface back to the inverter using either platform. I don't think that it is currently possible to write the settings back using either of the Home Assistant integrations. The Solarman integration does have the advantage of speaking directly to the Wifi dongle rather than going via the cloud API that the Sunsynk/E-Linter integration uses. I personally use the Solarman dongle on my DEYE but have a Sunsynk dongle as well for video's and testing. There was some talk of the Solarman and Sunsynk platforms cloud server update frequencies being increased to every 60 seconds instead of the default 3 minutes (I think). Not sure what the status is of this.

If you do monitoring, you need two RS485 adaptors (for my addon & solar-assistant). Even for ESPHome based solution. Can't tell you specifically for solarman or e-linter.

I must have a dongle somewhere around the house, will try test over the weekend.

For slave I used bms 485 port, it does not share the port. Thanks to @Magetsi I managed to ignore the initial errors and connected to the shared port on the master and got readings, my TX rx are 1and 3 and 16 is the control pin. I had errors before finding the right port in both instances. Aport from the pins and the soldering, finding the right port is important, I used @slipx yaml, it allows for reading and writing data,no more having to manually change the grid charging settings 1 by one, I do that on homeassistant with scenes as per the YT video from solar integrations. Good Luck Thanks for your reply, so after trying many different things, i have now managed to connect an esp to each inverter and can see the date of each. this part is now working perfectly. My next challenge is as follows: Not sure if you have managed to find a solution. I am using values taken from two sensors and adding them in a template sensor. sensor.sunsynk1_slave_total_load_energy (slave inverter) sensor.sunsynk_master_total_load_energy. (Master inverter) # sensor.sunsynk_total_pv_energy sunsynk_total_pv_energy: friendly_name: Sunsynk Total PV Energy value_template: "{{ states('sensor.sunsynk_master_total_pv_energy') | float + states('sensor.sunsynk1_slave_total_pv_energy') | float }}" unit_of_measurement: "kWh" I have renamed the template sensor sensor.sunsynk.total_pv_energy This value however does not display correctly on the graph and shows as “undefined” Below is the .yaml code used for the graph. type: custom:plotly-graph view_layout: grid-area: daily entities: - entity: sensor.sunsynk_total_pv_energy statistic: state name: | $fn ({ ys,meta }) => "Solar" + "🔆" + "(" +ys[ys.length - 1]+"kWh)" period: day type: bar texttemplate: '%{y}' filters: - filter: i>0 marker: color: rgb(255, 155, 48) I have tried to include device_class as per a suggestion i received on another post but it still does not read the value. However when entering the entity it shows a state in this case 9793.6. image1037×333 40.3 KB Below is the code showing device_class Does anyone know what could be the problem. # sensor.sunsynk_total_pv_energy sunsynk_total_pv_energy: friendly_name: Sunsynk Total PV Energy value_template: "{{ states('sensor.master_master_total_pv_energy') | float + states('sensor.sunsynk1_slave_total_pv_energy') | float }}" unit_of_measurement: "kWh" device_class: energy_storage
September 1, 20232 yr That plotly graph will start populating once there is sufficient long term statistics collected. Give it some time.
September 1, 20232 yr It has been running like this for days now and there is no if shown on the solar. , The issue I have with the template sensor created for "sensor.sunsynk_total_day pv" is that it does not read the state. State is shown as undefined. the other sensors read correctly, however this is info taken either form the master or the slave inverter. As soon as I create ethe combines sensor template, I get the same result.

Yes, you would need a cable to each to pull individual power/energy stats. It's only the settings/system mode controlled from the master. Thank you for the response. I have your integration running at home and have disconnected Solar-assistant. They are not the old parallel connectors from printers. They are actually using DSUB like connectors. Like 15 pins times two for each battery module. These BMS units actual have a temp sensor per cell apparently. But as for my parents setup, there I need to try figure out why their batteries are not actually able to communicate over RS485. Could only get them to work with the Revov RCUv2 RS485 to CAN module. What would be awesome is being able to tunnel the RS485 comms of the battery through a Pi or ESP32 to the inverter and have the comms to the inverter. This is only really for my parents setup as the have the newer E-linter units and I do not want to rely on the cloud for data to HA. Thank you for an excellent integration addon. There is a LAN version of the E-linter dongle on its way. I just need to ask my contact to push them for direct LAN access to the units. Would be useful on the Wifi versions as well.
