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 financ
This is a known issue. I've come across a bunch of their inverters that have
had this problem. In addition to seeing this issue on their 1800's I've seen it
happen on their 2500's as well. Shows a solid green light but isn't putting out
power.
The first time I came across this issue they had a

SMA used to to do repairs but last I heard they no longer have replacement
parts. I have used the new SMA TL-22 because of the low voltage dc input. If
you added some additional modules to the "B" input it might qualify for the tax
credit (I did say might)

How do you get around the code requirement for the use of PV wire with a TL
inverter on the existing array?

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

All the way back to the module jboxes? Sounds pricey.
That is assuming the module jboxes accept conduit.
Indeed it I not only the home runs that need to be concerned with the PV
rating, but the module conductors as well, as there is no distinction made in
the code between them.

Glenn
There you go, I just assumed it was

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
Bill,
Thanks for chiming in and going on the record with a good position!
