[RE-wrenches] SolarEdge v Enphase

[conrad geyser]

Andrew,

 

We installed a Solar Edge system on a 5 kW this spring.  We've had to
replace all the optimizers and the inverters.  They've been OK with support
on this but perhaps a bit slow in throwing in the towel making us go back
three times.  Maybe the bugs are out by now but our experience wasn't one
I'd like to repeat.

Does anyone have any experience installing SolarEdge?  The advantage that I
see over microinverters from a reliability standpoint is that the power
optimizers do not contain electrolytic capacitors.  The inverter is also
supposed to last longer since it does not handle the MPPT duties so the
electronics are less complex.

 

Marv - Do you have any SolarEdge reliability and / or performance data you
can share beyond the white paper on the SolarEdge website?  Also, one issue
that I've had with Enphase is an occasional loss of data transfer between
inverters and the monitoring system - does SolarEdge have that issue?  If
not, how have you overcome it?  Can you share a link to a live SolarEdge
system monitoring interface?

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....
