Re: [RE-wrenches] SolarEdge v Enphase

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

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

Wrenches, I wish this urban myth about electrolytic capacitors would die, but it won't.  It's been a wonderful marketing ploy for some time now. Simply stated, existence of electrolytic capacitors in inverters does NOT mean the inverters are less reliable.  Satellites have been using

Dan, Thank you SO much for that post. You are absolutely right on. EVERY component in a circuit can be the weak link. Component quality, design margin, and actual use conditions really dictate what is going to fail, and when. See ya! Marv Director of Technology and Support, North America

Once again Dan, you nail great information to this board. Key phrase: used within its specification Back in the '80's I replaced hundreds of small caps in very poorly designed 2-3 year old C-band satellite receivers, all damaged by excessive internal heat. Thanks for your input. Larry

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
