[RE-wrenches] I know you've all said, "I told you so..." SolarEdge...

Fri May 24 13:38:10 PDT 2024

This wasn’t an RSD rant (and thank gosh NEC2023 clarifies and reduces some silly RSD requirements), but a rant over the damn finick-iness of the BUI and multi-inverter setups from SE. 

I’ve developed a nervous tik that comes on with lighting and storms and hits a peak when phone rings from customer immediately after the storm…heck, even the surge from the grid utility coming back seemed to freak out the one I was at yesterday which was operating fine in backup mode.

Can’t say many didn’t say, “I told you so.”

Enjoy your weekends. Scot

Sorry but my previous post went out before I finished my thoughts.

I know MLPE electronics can be a pain. I hated the RSS requirements when first introduced. However solar energy sources pose unique safety concerns. There is no safety disconnect on the sun. IMHO, having a means to safely work on high voltage PV circuits during daylight hours is worth the added cost and inconvenience. 

With all due respect.  Rant off.

Well to me the final, final straw is their stock price losing 2/3 its value in a year.

I tell all of my clients if you ever have to do roof solar, you should use a central inverter and not ever put electronics on a roof. Bad enough to put solar panels up there!

SolarEdge…I keep saying they fixed their reliability issues, but the latest storms in Central Texas leave me again with frustration. Some systems worked, others did not. Worst was ones that were surge-sensitive as grid utility power was restored so a system in backup yesterday turns into a service call with the grid back, as a finicky BUI transfer switch didn’t go back to grid power.

Make the run to the affected customer and wait and wait and wait for tech support, only for them to finally take my call after I’ve packed everything up (how long must we wait for a call pickup?) and the first question is “send us pics of the installation.” Of course that is to grade the work and despite me saying we replaced a comms card in November, and don’t you have that picture still? I get the tier-1 blocking before I get to tier-2.

I’ve had a lot of final straws with SolarEdge, each time assuaged by a “we’re fixing reliability…we’ve improved tech support” but objectively, this company drives most of my reliability frustration. Intra-“box” comms are so finicky. I’ve told them they have Backup Interface Units that get stuck between grid and backup during the rapid on and off utility outages that come with many storms and they try to say “we have not seen that” but I tell them I gave five examples just from me!

Vent over…know many of you have left SolarEdge and I suppose its stock price a manifestation of that.
