[RE-wrenches] Enphase Application

[Bob-O Schultze]

Mark,
Not to criticize your math or your premises, which I agree with, but  
we really should be using list prices when we make comparisons here.
This is a publicly viewed forum.
Ya know??

Humm...

14000 kw / 200w mod = 70 mods = 70 micro inverters,  70 * $161 = $11,270
plus $635 EMU = $11905 cost for inversion

Verses

2 x 7.5 kw Fronius inverter = 15000 kw,  2 inverters * $3877 = $7754  
cost
for inversion

That's a $4151 delta on inversion cost, a 53% increase over standard  
string
inverters. No experience needed.
