Hi, we need an electrical engineer to assist us with a circuit design problem. We have a solar charge controller and an AC/DC power supply and need the solar to operate a load and if there is excess power send this to Load2 which is being powered by the AC/DC power supply. So we need a one-way junction circuit and know there must be off-the-shelf devices to do this but need some help please. See attached drawing. We want to achieve this using off the shelf components such as reverse protection diodes and NOT to have a microprocessor or software if possible. Many thanks, Mark

Hello, thank you for your job posting. I read your description about--CIRCUIT I am a senior electrical engineer. I have plenty of experience in firmware development and micro-controller developments. I can write the firmware based on Arduino, Raspberry Pi, Pic, Atmega, FPGA, ARM, DSP, PLC and so on. And I can design the circuit by the Altium, Eagle, KiCAD, Allegro & OrCAD, PADs. I provide the services - Gerber files, Netlist generation, BOM generation and 3D Models of PCAD and ECAD. I am also good at AutoCAD, Solidworks. And I can simulate all circuits with Proteus, LT-spice, Matlab, Simulink, Multisim, and Labview as well. Due to my experience in firmware development, I will bring you the perfect result in time with high quality. I will also give you a detailed explanation of the process. Looking forward to hearing from you soon Thanks

Hi! I am an Energy and electrical engineering Expert with over 5 years experience in performing solar system feasibility studies, design, installations and commissioning including ESS design from Residential, Commercial Rooftop and Utility scale systems from kW scale to a MW scale both for public and private sector. I have done similar work and it is my specialty as you can see my company profile here on the freelancer but can also check our website for your reference. I will be able to perform these designs efficiently and according to your specifications and scope of work including specific instructions and according to the national / international standards and regulations including policy requirements. I can also advise or recommend best approach on carrying out design from inception to execution. I am using AutoCad, Revit, Aurora, Helioscope, RETScreen, PV SOL** , Digsilent and a bit of eTAp and PV Syst and other tools to perform this work. I am also experienced in design of medium to high voltage distribution lines from 0 Volts to 132 kV line including substations for solar plants. You can also recommend your preferred tool to be used for both energy production assessment, designs and economic analysis to find best Levelized Cost of Elelctricity (LCOE) if required. Let chat, I am happy to start project design. Please check my work in freelancer profile (https://www.freelancer.com/u/mhunubi) .
