arc fault protected inverters NEC 690.11

[mikesimpson5]

Has anyone had problems obtaining inverters complying with NEC 2011 690.11? Especially in New Jersey

As far as I know, the only 690.11-compliant inverter options are available today are from SMA and Fronius:

With CA about to adopt NEC 2011, I bet the number of compliant products increases rapidly.

For larger systems w/ central inverters, SolarBOS has listed AFCI combiners:

I just had this problem. Supplier told me the DC disconnect for the SMA SB6000US inverter is not available in the AFCI version. (for many SMA inv.s the DC Disco contains the AFCI)

The new TL-X000-US series has built in AFCI.
But it does not go up to 6000 watts.

They're saying the D/C doesn't meet AFCI? The spec sheet led me to believe the 6000 is ACFI compliant out of the box, no?

His supplier may have old stock.

Yes, many different DC Disconnects exist for the 6000 and larger SMA inverters. Only some contain AFCI.
Some are "made in Canada" or whatever and qualify for their subsidies. MAybe other kinds too???

GGUNN, thanks i followed your link. It says,

• Optional integrated AFCI functionality meets the requirements of NEC 2011 690.11

Of course, they start by writing AFCI!!! in big letters everywhere.

[All of the new (very awesome!) 3000, 4000, and 5000 SMA TL inverters have AFCI.]

Power One has compliant inverters as well
