[RE-wrenches] SolarEdge v Enphase

[Mark Frye]

Indeed.....
 
Yes it is 1v per module when not operating, but still >250V when operating.
That means that all code requirements for >250V still apply to the DC wiring
such as bonding bushings for conduit as required etc.
 
SolarEdge is making hay off of this safety feature, but this feature is
inherent in microinverters as well.

Mark, 
I thought that the SolarEdge reduced the 'string' voltage to 1V per
unit/module, reducing the high DC voltage risk factor, until the inverter
switch was turned on?

The fact that by hitting the "off" switch on the inverter will reduce the
potentially high DC voltage to 1V per unit/module could be an advantage from
a safety perspective (maintenance, firemen/utility workers)

Labor/time-wise, it is like installing both a microinverter system and a
string inverter system together, soooooo....
