The prototype version is still going strong, but I still need to draw the controller pcb.
Today I saw 84A peak, good for more then 4600Watts in to the battery!
The unit is fused with a 63A breaker so it allows this kind of peaks.
I must say the inductor is cooled actively, at this kind of power it gets hot, +/-90°C.
And important, the tracks are short but the board is only 1oz thick, so the pcb is getting hot as well.
The unit is now running allmost 2,5 months without problems. There is 5600W panels connected. The final install will be verry conservative @ 40A max per unit.
