[RE-wrenches] Any experience with Power-One AFCI inverters

[Jeff Irish]

Yes it's real and they are apparently working on a fix.  As we were told, the problem only occurs when there are two or more paralleled inverters, and only with the small 3 to 5 kW units.  I believe they interfere with each other.  I'm not sure if it occurs all the time or only in some instances.  Our state is not requiring AFCI yet so we are requesting non-AFCI units from Power-One for the time being.

All -

As many of your are aware, the 2011 NEC is coming to California in the new year and so we'll start installing AFCI inverters on our projects. Has anyone had experience with the AFCI string inverters from Power-One? I've heard through the grapevine that some people have had problems with Power-One's AFCI circuitry tripping when there aren't any faults and thought I'd check to see if this is just a one-off experience or if it is widespread.

Thanks,

August
