I would like to develop a device that can communicate a device that can interface with a grid tie inverter via a RS485 interface using Arduino. The inverter has a set of parameters that can be requested by the inverter protocol, as well as a set of instructions that can be sent to the inverter. The successful bidder will implement all relevant requests and instructions included in the inverter protocol sheet (about 12 requests, and 3 instructions which will be supplied). Data must be logged to a SQL database via WIFI/Ethernet/USB, and must be visible on a small LCD screen. A set of 2 or 3 buttons must be included to manually adjust settings, or view different parameters. The project is subject to a non-disclosure agreement. Please only bid if you have experience with commercial RS485 communication. Deliverables will include the full code, a list of components and if possible a simulation. A variation of the project on another platform, such as Raspberry pi, will be considered.

NOTE: I charge higher than other freelancers available and take relatively more time but don't compromise on the quality. So please ignore my bid if you're VERY short of budget and time. ============================================================================ Dear Hiring Manager, I'm a professional electrical engineer and have made more than 200 projects for local and international clients. You can have a look at my profile and read the wonderful reviews about me. ============================================================================ Regarding your project: ================== I've hands on experience in working with Arduinos and programming microcontrollers + RS485 interface. In fact more than 80% of my projects include some kind of microcontrollers. Moreover, you can have a look at my past projects and I've also built a grid tie solar inverter, but that was without the interface. I'm perfectly okay with signing NDA for the project and start the wonderful experience together. The services I will provide you include: 1- Circuit Design. 2- Neatly written, full commented code. 3- Bill of materials. 4- 110% satisfaction. 5- Free support even after the completion of the project. 6- Prototype built (costs of materials and shipping to be provided by you) My demands from the client: ===================== 1- Be high on budget to get awesome work from me. 2- Be patient and provide as much time as possible to finish the project and I'll meet the deadline.

Hi, I believe you want to create a console for an inverter with RS485 serial interface. Though it is standard RS485 interface, it depends on how the interter is implementing the commands. I have worked on several projects involving serial (using Arduino/raspberry pi and PC) using corresponding interface (to match with rs485 serial lines) like interfacing industrial boiler, interfacing with mdb cashless device etc. Let me know more information about this. Thanks!

Hi I did the same thing for rectifier and DGset. Rectifier and DGset Status can be acquired using RS485(Modbus) or SNMP Protocol...... Then the status is transmitted to remote location using Ethernet.... I used Arduino Ethernet shield that is mounted on an arduino mega. Arduino Mega make requests and acquires data from DGset... Then through Arduino Ethernet shield it makes connection to server and Posts its data their.... I also published data on Server using WIFI Module ESP8266............ For further discussion on project you can message me any time... Fell free to contact me..........
