Re: [RE-wrenches] After market SMA TL inverter shade covers

Andrew We had some problems last year with some of the fronius primos leaking in rain / wind conditions. Customer had a local shop tig weld an aluminum shell / box that went around the unit. Had a shelf at the top that stuck out like the brim of a hat. Worked great. We had also looked for

Re: [RE-wrenches] NRTL certification question

Jerry, it is for off grid, but that's not synonymous with non permitted. This is a house being built with standard permits. Unlisted modules are only appropriate for "unpermitted owner-built homes too remote to be discovered by the AHJs". It's a specific category of its own. We have

Re: [RE-wrenches] NRTL certification question

Hi Allan, TUV is now an accepted NRTL, but the equipment still has to Listed to applicable UL Standards to mean anything. Testing only to European standards doesn’t cut it here. “CE” is meaningless here also. Brian Teitelbaum AEE Solar *From:* RE-wrenches

[RE-wrenches] NRTL certification question

Allan, OSHA maintains the list of NRTL’s: https://www.osha.gov/dts/otpca/nrtl/nrtllist.html. TUV Rheinland is included, but CE is not a NRTL – it is a manufacturer’s declaration of conformity (literally translated is European Conformity) to European requirements for product conformity. As a

[RE-wrenches] NRTL certification question

Wrenches, And now for something completely different... are TUV Rheinland or CE module certifications valid yet in the US? I was called to consult for an off grid client who had purchased 40 250W generic Chinese modules through a friend who got them on Ebay... yeah, right. I got to be the

Re: [RE-wrenches] Low array voltage stumper on legacy system

Mike, Jay's suggestion to turn off string three, the low one, is good. Plus I can guide the homeowner by phone, thus avoiding the cost of another site visit, so that adds appeal. I just spoke with him. While he lacks the DMM and DC amp clamp, he is going to record V and I in and out for each

Re: [RE-wrenches] Low array voltage stumper on legacy system

Your measurements of the Isc for the four stings seems to be odd in string 3 with only 2.4A. However, when you measure the circuit under load, you are getting 14.6A from all 4 strings, which averages 3.65A. I’d say check that string again, perhaps the current clamp wasn’t zeroed or something.

Re: [RE-wrenches] Low array voltage stumper on legacy system

Steve, Yes, in the same sequence: 75.5V, 73.8V, 73.9V, 74.0V. All just about what I'd expect. Brian, I have seen that with KC120s over the years - good Voc and Isc but no MPP. That's a known failure that Kyocera (to their credit) continues to warrant 15 years out. But I haven't seen it with
