Building mppt-2420-hc

i like to build a mppt-2420-hc.
Is there somebody (located in germany), who wants to join this rebuild.

My system setup:

  • 2*375W solar panel with 80V input
  • 48V LiFePO4 bat

I am thinking about this modifications

  • Maybe, redesign to a available uC (STM32L051C8T6 ?)
  • Maybe, redesign of other not available parts
  • Socket for ESP-01 module
  • Maybe support for cheap (jlcpcb) 35um PCBs
    (add 2.5mm2 copper wires for high current signals)

Any comment regarding this?

Somebody like to join this rebuild?
