I have 26 230 W 24 V solar panels. I also have 20 circuit boards each board has 10 mosfets? or IGBTs that are 290 V 40 A each one as a 20 amp fuse beside it there are other components on the board to drive the FETs. Each board as a + and - 15 V and a shielded input cable. I would like to use some of the boards to make a charge controller, possibly MPPT. does anyone have any suggestions on how this could be done?
Thank you
Craig
