Designing a digital 20A buck boost SMPS

I would like to create a digital SMPS with these specifications:

Input: 20~45V, 20A

Output: 29.4V +- 0.1V (configurable in the range 25~34V)

Current: 20A continuous, or more

Efficiency: > 85%

Must be digitally controllable: though serial, SPI or whatever, we must be able to control output voltage => most important part

Input GND should be linkable with output GND => I was thinking about a SEPIC topology

I'm searching for someone able to design such an SPMS. Providing me an electronic schema and a BOM of the components available in common electronic stores.

PCB design and manufacturing is a plus.

------------------

Full project description:

This SMPS is just a part of a bigger project: I'm aiming to create an "IoT" and scalable solar power solution:

- X parallel solar panels (0~42V, 300W, 30V 10A peak)

=> connected to

- N parallel SMPS, able to deliver constant current, floating voltage and vice versa (floating current, fixed voltage), where the max voltage and current will be defined by a "master". Moreover, current and voltage monitoring (both input and output) should be a must have, where an OV, UV and reverse protection is a nice to have. So in reality, 20A is just a number I took to mitigate the cost but it is not a fixed choice, 10A would be fine if it cost 2 times less.

=> connected to

- L parallel 7S lipo batteries with BMS

=> connected to

- Y inverters

Each of there parts must be "plug and play" and "IoT" to enable high scalability and monitoring

Hello, monsieur. I have several ready-made solutions to a similar problem (it would be strange if they had not been in 20 years of my practice). About SEPIC ... I have to do a little calculation. The output current bot Lagi
