Re: [RE-wrenches] Stackable Battery-Based systems complying to IEEE 1547-2018 standard

Mac – what utility is this? My understanding is that IEEE 1547.1-2020 contains the details of the testing protocol so that devices CAN be listed to 1547-2018. It got published in late May 2020. Are ANY inverters listed yet? My understanding is testing is a months long process and that would

Re: [RE-wrenches] Stackable Battery-Based systems complying to IEEE 1547-2018 standard

Yes, seems a little heavy handed to require this so quickly out of the gates. This is Rocky Mountain Power specifically Eastern Utah, owned or operated by Pacific Corp. This may be a way to get the customer to pay for a transformer upgrade. They offered an alternative to this compliance by utili

Hi Wrenches, I am working on a design for an all-electric home whole-house backup. The utility is requiring either an inverter listed to IEEE 1547-2018 or utilize an effective grounding transformer with associated relay control system. Im unclear whether the grounding transformer is on the custom

[RE-wrenches] SolarEdge Site Monitoring Administration Rights Transfer Form

If anyone has a copy of this form, can you please send it to me off list? I don't understand why SolarEdge hides access to this document and makes it so hard to take over another installer's site. I'm cleaning up a lot of messes recently and it's really hard to support these service clients.

I use a pair of magnetic boots, "Cougar Paws" be careful read & the fine print as they have many styles for “roofing” but only one for magnetic. Fit well and offer good support. when I move around on the ground I slip on a pair of “booties” over the shoes so I don’t pick up metal that might scra
