I bring to your attention the program for monitoring a solar station on Deye inverters.
The program is still under development, but the presented functionality works.
You can download and use it.
Program website: http://doro.poltava.ua/dsolar/index.html
The program interface is in...
No connection is required to collect information from inverters.
The dSolard information collection server works on a local network. The database is also hosted on your hardware.
You can view data using dSolar both locally and remotely via the Internet.
I Created a demo login, which makes it easier to familiarize yourself with the current functionality of the program.
For this you need:
1) Download the dSolar client program for Windows or Linux or Android using the link:
2) Run the...
Anyone using "low power mode"?
It doesn't work for me.
I have a parallel system of two SUN-6K-SG03LP1-EU inverters.
Low Bat set as 51.2 Volt.
Time Of Use Voltage set as 51.1 Volt.
Checker for "Low Power Mode<Low Batt" set is on.
Grid is connected.
PV is disconnected.
The battery voltage...
New version of dSolar program ver 0.0.5 from 13.04.2023:
* Sensor portrait orientation of the screen
* Message from the server
* Optimization of statistical requests to the database
* Assembling the dSolar server for Linux x86_64 architecture
It seems to me that it is necessary to add a certain algorithm for disabling the slaves inverter. For example, in the absence of solar generation and low load - turn off slave inverter. And turn on the slave inverter when the load increases or the sun appears.
I tried to turn off the slave...
New Version ver 1.0.0 (09.05.2023)
* Checking the existence of a new version
* PV graph for historical data
* Assembling the dSolar client for Linux x86_64 architecture
* Control of 4-channel Wi-Fi relay to use excess energy
* Control of transition to absorption, float, charge/discharge battery...
I have two inverters sun-6k-sg03lp1 connected in parallel that work without a grid (only with pv and battery).
The photo shows the actual self consumption of two inverters for the month of May.
Self consumption is quite significant.
Does anyone have any ideas on how to reduce the inverters self...
I have the same battery. I want to connect to my solar station monitoring program.
Was it possible to fully decipher the protocol?
Is it possible to read the description of this protocol somewhere?
Something is happening, but what it is is unknown.
When I sent a command to the slave inverter, the slave and the master stopped generating to the load.
The master issued an error about the loss of communication with the slave.
Both inverters continued to be powered by the battery.
I have two questions, I will be sincerely grateful for your help.
The first question:
Can I turn off/on or put the inverter to "sleep" mode by sending a modbus command to it?
The second question:
What does register 043 of the modbus protocol mean. They named it as: "Switch on and off enable"...
Thank you for the answer.
I think the Deye would also turn off without problems.
The problem is that I have a parallel system of two inverters, one of which I turn off.
I do not have a description of modbus commands for three-phase inverters.
Could you please share this description with me?
