Re: [RE-wrenches] SMA 1800u not generating power
Is another possible solution.use the prior version of the SB (non-TL)?, of course if the VDC of the strings works out. You wouldn't need to worry about any of the wiring, or trying to convince a clueless AHJ one inverter in safer than another. I've used exclusively TL's in all my installs lately, I assume the non-TL SB's are still available.

The TL has arc-fault detection and much better ground-fault detection. Conduit is not the answer since it breaks several other code requirements like the module manufacturer’s instructions (110.3(B)).

[RE-wrenches] SMA 1800u not generating power
I am looking at a 1800u from 2004 that has a green light and in mpp mode, but Pac is zero. Grid and DC voltage are good. No other indication of problems. I saw Pac tick up to 2W a couple of times, but that's it. It's just not delivering AC power. Any thoughts? Sadly, it doesn't make much financial sense for the owner to replace it with a current model, as the replacement cost would take almost 10 years to recover with the small BIPV array connected to it. I'm hoping for a field repair option.

Someone contacted me off list and said this company does out of warranty SMA repairs: http://www.shop.solarcowboyzoutlet.com/Inverter-Repair-Service-Inverter-Repair-Service.htm Looks like there is a risk in how big the repair is, but apparently they are willing to talk about the diagnostics before you send it in, and fix minor problems for a flat rate. One bad part about these small systems is that labor to repair or replace failed units can easily turn into a cost equivalent to years of energy production, not to mention the hardware cost itself... I've only sold a few tiny systems over the years, and never really considered this.

All the way back to the module jboxes? Sounds pricey. That is assuming the module jboxes accept conduit.

Something should be written into the code to allow old systems to use TL inverters for upgrades, especially since TL inverters are safer than their transformer based (isolated) counterparts. For now I guess we either make a decision to source transformer based inverters for replacements or install TL inverters despite the code violation.

Re: [RE-wrenches] SMA 1800u not generating power
Glenn, While the installation may not claim exact compliance with the current NEC (debatable), you can easily show that the TL inverter is much safer than the older 1800U. The TL has arc-fault detection and much better ground-fault detection. Conduit is not the answer since it breaks several other code requirements like the module manufacturer’s instructions (110.3(B)). Bill Brooks.

Re: [RE-wrenches] SMA 1800u not generating power
Hi Glenn and All – Most of these old systems have module cables made out of USE-2. So, just changing out the array USE-2 home runs won’t technically cut it. Something should be written into the code to allow old systems to use TL inverters for upgrades, especially since TL inverters are safer than their transformer based (isolated) counterparts. For now I guess we either make a decision to source transformer based inverters for replacements or install TL inverters despite the code violation. It is definitely a bummer that SMA isn’t doing the refurbished program anymore with their old units.
