MPPT

Hello. I'm a PCB designer / electrical engineer. Your project interested for me. Also I ask you about existing board. Can we use it as starting point for new design? Wait for your response - please write in PM. Will do my best, Viktor.

I have over 35 years experience as an electronic design engineer, please see my profile for more details The current price and timescales are only place holders to allow me to communicate with you I wonder if a design based on the BQ24210 would suit your requirements? If you think I can help then please send me further details including the current and voltage that the LEDs require and all the various modes of working required. Best Regards Dave Lelievre

Hi, If you are still in search and didnt find the right person to do this job then lets discuss. Will design the product, build and test a prototype and deliver fully functional design. My job includes programming of the microcontroller as well. I did a very similar project but not for powering LEDs or LiPo battery. It was for VRLA Battery instead. Lets discuss and will do the job nicely. Thank you. Regards... Roy

Hello Dear, We are a ream of experts with a cumulative experience of more than 50 years in the field of embedded systems and prototype development. Our experts have hands on experience developing ultra low power solutions with complex computations. We work in smart grid, wireless, telecommunications and automotive. I have checked the details of your project and shared the same among my team. We are happy to offer you our services for the prototype development of this charge controller. The break down is as under 1) Schematic design ------------------------------- 250$ 2) PCB layout with 3D Modelling------------- 350$ 3) PCB fabrication and BOM ------------------ 400$ 4) Firmware Development ---------------------1000$ 5)Samples and shipment -------------------------500$ I am online and available for discussion.

Hello, Have a great day. We are running a setup for developing Electronic devices. We will ship you fully working hardware. Please feel free to contact us. (i have a product that uses this circuitry it was built by me couple of years ago) Regards, Shahbaz.

Hi, I have recently been working on a design for data logging device that importantly utilized a solar cell and energy harvesting technologies as its only source of power. There are a number of excellent solutions available. There are obviously many questions related to how you plan to implement and use the energy collected, but other than driving LED's, your project description is short on specific details. I have the skills required to design the device including schematics and PCB's and to build and test. Always happy to discuss the project. James Harrison-Smith

Hi, I am a post graduate power electronics engineer and having very good industrial experience of 8+ years in R&D and project development. I am excellent high frequency transformers design, circuits design, multi-channel LED Drivers, Regulated power supplies design with universal input to DC output, Audio amplifier, drives design, Filters design for harmonic analysis and Power factor correction, SMPS, LED drivers, DC-DC, AC-DC converters design, PFC interleaved boost converter, Battery management system, Battery chargers, UPS design, sine wave Inverters, solar grid tie inverters, Solar battery chargers and street light systems design from few watts to KW range using Buck, Boost, and Buck –boost, Interleaved boost/buck, Fly back Push Pull and H-bridge inverters. I have work experience to design from few watts to KW range meeting all compliances like EMI/EMC and safety standards UL etc.

Hello, I have an experience with 3.7v lipo powered long life devices. For example, one of my project the BLE tracker with a wireless charger. If you have interest you can ask me in chat. Best Regards, Andrew

hi I offer you 20A Maximum Power Point Tracking (MPPT) solar charge controller for 5V solar panel. This Solar MPPT Charge Controller including reverse battery protection and software programmable alarms and indications can be configured to detect over-current/undercurrent protection The design has an operating efficiency of above 96% at full load in a 5V system.

Hello I have read what you exactly need. However, I would like to ask you a few questions. I do work in a smart way and do not rest until I get the job done. Please feel free to ping me anytime so we can have a detailed discussion and finalize our budget and timeline. I will deliver in best possible way.
