Off grid solar station with an inverter connected to an external 3-pin socket need to track how many kWh's are discharged via the plug. Current thinking is tis might be a raspberry pi with a cellular modem, ideally connected to a clamp meter or similar Data sent to an IP address that can be accessed remotely in Excel or similar format. Does this sound achievable? If so, do you have any questions to be able to provide a quote. Ideal person is based in UK and able to help with hardware procurement and testing. Potential for future feature development Paul

I am an EE engineer. I have lots of experience designing both analog and digital circuits. In the field of simulation and PCB design, Proteus, PsPice, KiCad, and Eagle are softwares I have expertise in. I also have expertise with lots of past projects and examples in Embedded design for microcontrollers. Some of the MCUs I have worked with TI MSP430, PIC, Arduino, nordic semiconductors (i.e nrf52840), STM, MAX, etc. I am able to program devices using both Assembly language and C/C++ (both procedural and OOP). *for STM and nrf controllers Mbed OS could be one of the choices for programming the MCU. I have done lots of projects in the field of wireless communication and IoT using different wireless communication protocols like BLE, RF, WiFi (Cloud), etc. In the field of bit streaming, high-speed processing and ML, I am able to program both Xilinx and Altera in VHDL or C/C++ for Microblaze or NIOS II processors. For manufacturing purposes, I can provide component selection and BOM which suits your needs for a durable, efficient, and effective design. ABOUT YOUR PROJECT, I have done lots of similar projects before and can handle your project easily. We may discuss it more over chat. Cheers!

I have some questions about your project and would like to discuss it before I can propose a final price and timeline. Here are some of them: 1) Is it for batch-production or you would like to automatize a single installation? 2)What do you have on the mentioned IP address? Desktop computer (what OS do you have on it?) or, for example, Linux/Unix-based server? 3)Do you need data to be uploaded on fly - or it can be stored locally on RPi and uploaded periodically? 4) Should be the stored data available remotely (using some dashboard) - or you will get the mentioned file and use it in desktop computer? Clamp sensor is enough good solution for measurement, but to have the watts you need an access to the wires to also measure a voltage. In that case using of intrusive hall-sensor may be a more precise solution for measurement of the current. I have more than 30 years of experience in programming and electronics. Please feel free to contact me in chat.

Hello, I'm not a bot.. I am a Software Engineer and very interested on your project,I would like to help you. That's totally achievable, we can meassure the current using any commercial clamp meter as you said. I can create the software that will be running on the Pi and connected to a Google spreadsheet, or even a local webpage hosted in the same pi, accessed from anywhere, we can also use the any of the available IoT platforms to track the data in a smarter manner. I am not in the UK, but this can be done remotely without any issues, I will just need to access the pi with the clamp meter connected to it and to the power cables coming from the inverter. Waiting for your comments. Thanks Martin O. ~ If we decide to work together, your project will be guaranteed to be 100% completed, I have all the skills and tools to achieve it. If you rate my bid with 5 stars I will give you a 5% discount, does it sounds good?

Hello. I am an Electrical and Electronics engineer by profession. I work in an electric power company and I have many years of smart metering experience. I have worked with CEWE, Secure, Edmi, Hexing and Holley energy meters and related AMI systems. Here goes my options 1. We can use an energy meter with IoT support and Wifi. We setup a wifi network using a 4g Wifi dongle at the location and then connect to your server or some commercial IoT platform (Thingsboard, Ubidots etc. ), via MQTT. 2. Inverters usually has a MODBUS TCP output for reading data. If it is there, we probably can read the inverter's energy output using an Arduino or esp32 and then send to a server via 4G wifi dongle. 3. There are energy meters with 4G modem included. We might be able to find a one which will push the data directly to your server. (need more research on this). I have done this with custom made modems. 4. Raspberry pi + MODBUS TCP/RTU energy meter and 4G Wifi Dongle. We read the energy value to raspberry and post it to your server. We have more control over data reading and posting to server. I have implemented this for few energy meters. If you feel my experience and thoughts are in line with your requirement, I would like to give a try with your project. Thank you. Kindly note that I am not residing in UK at the moment.

Dear Sir, I would like to present myself as prospective candidate to do your project. I have sound knowledge and experiences in Electronic and Programming. Including schematic design and PCB design. I have read your project description. Use of raspberry Pi is a good idea. but it is not the most cost effective idea. I think a LiLY go (LILYGO® TTGO T-Call ) module is a cost effective. LiLy go include GSM modem and ESP32 module in single board. However a Raspberry Pi and GSM (or 4G) modem is program wise good idea. To measure power usage, there is a chip ADE7758 (manufactured by Analog Devices). This chip could measure and calculate energy usage. I have seen this have used in Mains Energy meters shown in YouTube. It is possible to send data to a IP and save in database to show in web page. I live in Sri Lanka, however I could assist on the project via any communication method. Please message me if you have any questions. Expecting a favorable reply, I remain. Isuru Athukorala
