with Enphase commercial applications and am currently working through a
commercial design. Enphase, on their M215 datasheets claim up to 25 micros per
branch, at 1.0A each, with each branch terminating at a 20A breaker. By
my calculations, 25 micros at 1.0A each (25A*1.25=31.25A) need to terminate at
a 40A breaker. Anyone know what I'm missing or know how the 20A
breaker design gets past the AHJ?</SPAN><o:p></o:p></P></DIV>
