Wrenches, What a delight it is when a client is so fully able to understand and follow directions! Albert, the homeowner of the 1997 system with 16 BP 75W modules on a tracker, sent the results below. In short, he isolated each string and measured input and output voltage and current as shown

[RE-wrenches] grundfos SQ pumps

HI All, I wanted to follow up that Grundfos does indeed have pump efficiency curves for the SQ pump. I was able to get copies from my main pump supplier, Preferred Pump. Grundfos seems to hold them pretty close and they are not generally available. I have a few of them, so let me know and

[RE-wrenches] Getting ready for 2014 NEC rapid shut down with string inverters

Hi Wrenches, I’m preparing for 2014 NEC 690.12 Rapid Shutdown to hit in California January 2017. Specifically, I’m trying to determine what to do for new string inverter based installations. I’m assuming that microinverter, AC modules, and systems with power-level electronics (SolarEdge etc)

Re: [RE-wrenches] Made three shut down

Hi Dana If you are in a lightning prone area surge protection is a must. OutBack has a surge protection device that mounts directly on the inverter (see the link below). http://www.outbackpower.com/downloads/documents/Hardware_Accessories/flexware_surge_protector/fw_sp_specsheet_english.pdf

Re: [RE-wrenches] NRTL certification question

Steven, Although you are correct that OSHA certifies NRTLs for specific test standards, I have not run into jurisdictions in California that reject products listed to UL standards by ETL, TUV, and CSA. There have been specific cases where the County and City of LA have questioned various

[RE-wrenches] NRTL certification question

Just to expand on this, the NRTL has to test to the specific UL standard. However, if you look at the definition of "listed" in the NEC, it states "equipment, materials, or services included in a list published by an organization that is acceptable to the AHJ...). I have heard of some

Bill and Jay, I didn't hear it from Enphase directly myself, otherwise I would have called BS. Around here, if they are on a north facing wall with no obstructions to the east or west then they would get some direct sun early and late in the day, for maybe a month or so in the summer. Hardly

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

Hi Wrenches. Yes, our product is NEMA 6, so is pretty robust once the DC and AC cables are connected. That said, our M215 Installation and Operation Manual states that the microinverters should not be installed in a location that allows for "long term exposure to direct sunlight." The
