Hacking GTIL On-grid Inverter
#1
I am trying to hack the Sun GTIL inverter's dc controller board (which manages the input side of the GTIL blue inverters) which uses a Microchip dsPIC33FJ64GS606 PIC. Am doing this because one of mine died, and I can not get a replacement board from the manufacturer.

I think the chip is still ok, just lost some of its code. The problem is that the PIC does not now implement the MPPT function to havest max energy from solar panels. It just drifts from 20-200 watts at random. The inverter was making correct power (about 1550 watts) just before the PIC lost its mind. Does anybody have any experience using Microchip's MPLAB IDE tool? Or does anybody know how to clone one PIC from a known good PIC.

I have the PIC spec sheet, and have ordered the Microchip MPLAB PG164100 Debugger.

thanks
