[RE-wrenches] SolarEdge v Enphase

Thu Jan 12 16:56:41 PST 2012

All,

We had a component quality problem with some early production batches.  Unfortunately  you guys in the field had to go thru a fair amount of grief before we wrapped our heads around what was going on, identified the root cause, and fixed the problem.  We absolutely stand behind the product, and also provide compensation for your time in dealing with our quality issues.

There are still occasional "glitches" in some installations, but the current generation of product is proving to be very reliable, and the "out of box" failures have dropped significantly.  Never low enough for me, though.

That's all I want to post here, but you know how to get in touch with me if you'd like to have further discussion.

See ya!

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....
