You can familiarize yourself with the functionality of the program without connecting to your own equipment. In demo mode, the program will show the real-time operation of my own solar station.

For this you need:

1. Download the client program dSolar for Windows or Linux or Android
2. Run the program

Architecture

Equipment

The dSolard server processes data from the following equipment:

Hybrid Deye/Sunsynk inverter Epever MPPT AN Victron SmartShunt

The equipment is connected to the Raspberry using specialized cables with a built-in inverter interfaces rs485 to USB (for Deye/SunSynk and Epever), VE.Direct to USB (for Victron SmartShunt).

Connection of the RS485->USB cable to the Deye/Sunsynk inverter:

Pinout of RS485->USB cable for Deye/Sunsync:

The dSolard and dSolar programs do not require any additional configuration operating systems on which they function.

Step-by-step instruction for install dSolard on Raspberry PI or Debian:

Step-by-step instruction for upgrade dSolard on Raspberry PI or Debian:

Recently, there has been a significant shortage of Raspberry computers. For my own use, I switched to a mini-PC.

Bought here: Beelink Mini S

I am satisfied with the computer.

Mini-PC as dSolard server

After starting the client program for the first time, you must specify the IP address of the Raspberry server in the settings:

Initial configuration

The equipment configuration is allowed only when the server is running in configuration mode:

And add your equipment:

Equipment

When changing equipment communication data ("Port" or "MODBUS Address") or adding new equipment - it is necessary restart the dSolard server.

After completing the equipment configuration, it is necessary to start dSolard server in normal mode (without attribute "configure"):

If the indicator is used on the main instrument panel where they are displayed generalized data on all generating equipment. Otherwise, data on specific equipment is displayed.

Solar panel indicator

Indicators of the indicator (from top to bottom):

1. Maximum power for the current day
2. Instantaneous power value
3. Percentage of the instantaneous power value relative to the nominal value (set during equipment configuration)
4. Energy generated during the current day

If the indicator is used on the main instrument panel, they are displayed generalized data on batteries. Otherwise, data on specific equipment is displayed.

Battery indicator

Indicators of the indicator (from left to right, top to bottom):

1. Battery state: Charge(Ch), Discharge(Di), Float(Fl), Absorption(Ab)
2. Maximum charging current for the current day
3. Maximum discharge current for the current day
4. Maximum charge capacity for the current day
5. Maximum discharge capacity for the current day
6. Battery charge in percent
7. Battery voltage
8. Instantaneous charge/discharge power value
9. Instantaneous charge/discharge current value
10. Percentage of power from maximum
11. Total charge energy for the current day
12. Total discharge energy for the current day
13. Remaining charge/discharge time
14. Energy in ampere-hours until fully charged

If the indicator is used on the main instrument panel, they are displayed generalized load data. Otherwise, data on specific equipment is displayed.

Load indicator

Indicators of the indicator (from left to right, top to bottom):

1. Maximum load capacity for the current day
2. Instantaneous load power value
3. Percentage of power from maximum
4. Total energy consumed by the load for the current day

If the indicator is used on the main instrument panel, they are displayed data over the public grid.

Grid indicator

Indicators of the indicator (from left to right, top to bottom):

1. Frequency of alternating current of the grid
2. Maximum power consumption for the current day
3. Maximum export capacity for the current day
4. Off Grid - signals the physical disconnection of the grid from the inverters
5. Instantaneous values of power, voltage and percentage of instantaneous power from equipment power
6. Total energy consumption for the current day
7. Total energy exported for the current day

Indicator is used on the main instrument panel where they are displayed data from the sensors of the transducer.

Temperature indicator sliders have dynamic initial and final temperature values, which are, respectively, the minimum and the maximum temperature value for the current day.

Transducer indicator

Indicators of the indicator (from left to right, top to bottom):

1. AC frequency of the transducer
2. Transducer voltage
3. Transducer efficiency(useful energy ÷ all energy) and the power lost during invertion
4. Current temperature value of the DC transformer
5. Current radiator temperature value
6. The transducer's own energy consumption for the current day

When clicking on the Solar Panel Indicator opens the PV dynamic data window. This window presents the data in section existing equipment (MPPT tracker). Textual, graphical, diagrammatic information is displayed dynamically with a second-by-second change based on the latest sensor values. For graphs, you can specify the visualization of data for the last minute, the last ten minutes, or the last hour.

General PV dynamic data

Device PV dynamic data

Clicking on the icon located in the lower right corner of the solar panel indicator opens a window of historical PV data. Histogram of energy and graphs by sensors.

PV energy per day

PV energy per month

PV energy per year

Historical data on equipment sensors is available for any day. Graphs can be scaled to the seconds interval.

When clicking on the Battery Panel Indicator opens the Battery dynamic data window. This window presents the data in section existing equipment (Inverter). Textual, graphical, diagrammatic information is displayed dynamically with a second-by-second change based on the latest sensor values. For graphs, you can specify the visualization of data for the last minute, the last ten minutes, or the last hour.

Battery dynamic data for SmartShunt

Clicking on the icon located in the lower right corner of the Battery Panel Indicator opens a window of historical Battery data. Histogram of energy and graphs by sensors.

The energy diagram is supplemented by two graphs:

• "Δ Delta" - the difference between charge and discharge energy
• "Σ Summation" - the amount of energy from the beginning of the day/month, year

Battery charge/discharge energy per day

Battery charge/discharge energy per month

The program informs about server communication problems with the equipment by showing the server message icon on the dashboard.

Server message on dashboard

Clicking on the icon takes you to the window with list of all existing server messages. Also, this list is available from the main menu.

List of Server message

Viewing the full text of the server message is also available.

I use the first channel of the relay block to dump the excess energy to heat the water. And uses the second channel of relay block for disconnects the grid when it is not needed.

Consider the rules for turning on and off the water heating relay:

Configure relay block

Water heating is turned on if:

Water heating is turned off if:

Manual relay control is also possible:
