    Bringing old Microinverters into NEC 2020 compliance

    Would you happen to remember if the landscape version was available back in December? I can no longer find it on the enphase page. Do you still see it?

    Engage Cable Landscape needed - but I have mostly Portrait.

    I guess I could do multiple Junction boxes in between the engage cable connectors to lengthen them from portrait size to landscape, but that would be a lot of J boxes. From what I see there is not a significant amount of voltage drop that would result from this extra splicing if the wire nuts in...

    Engage Cable Landscape needed - but I have mostly Portrait.

    I bought 34 M215 Enphase Microinverters on ebay about 6 months ago. The Engage cable that came with it has 10 connections of which are landscape - the 24 other connections are portrait. However I need to have 32 landscape length connections. How would you fix this? Buying options for Engage...

    Rapid shutdown switch question

    Like something like this correct? https://www.eaton.com/us/en-us/skuPage.DG222NRB.html My plans are to have M215 MI. My understanding is that turning the AC off would then start the Rapid shutdown process. I have the isolator on my pergola structure as the additional gap for when work needs to...

    Rapid shutdown switch question

    What would be the difference then between an AC Isolator and a Rapid Shutdown Switch? Or are they the same thing...

    20 or 30A breaker for Enphase Combiner receiving 16 M215 Microinverters

    That is SUPER helpful to know as one of the many reasons I am doing this is that there is very few solar installs in the area. Initially I was going to work with a solar cooperative, but that fell through and so that has evolved into this current 6 month odyssey. How large is a typical packet...

    20 or 30A breaker for Enphase Combiner receiving 16 M215 Microinverters

    Thanks, I did ask my local utility if they had issue with it and no comment. So my path currently is to get Inspector approval - then submit plans to the utility for final determination. Could you expand more on what you mean by "You need to make sure you have 6.9kW of charging and inverter...

    20 or 30A breaker for Enphase Combiner receiving 16 M215 Microinverters

    Thank you, UL1741 only - no SA. My current understanding is that I will then have sudden shut offs and not be modulated. Am OK with that. Would that be an issue at all with Grid Tie in? Yes I have seen the posts on the issues. I was able to get Used M215s and used PVs and so that is what lead...

    20 or 30A breaker for Enphase Combiner receiving 16 M215 Microinverters

    That now makes more sense to have it limited to 20A breaker based on Manufacturer's specifications and that will protect the 12 AWG of the Q cable (75C rating of 25A 90C rating of 30A but then would need to be Temp derated). Thanks for helping me think that through. So in terms of landing...

    20 or 30A breaker for Enphase Combiner receiving 16 M215 Microinverters

    Attached is the latest version after amanedments. The other thread I tagged you in has the original plan. The updated version has the correct Temp ratings and other improvements.

    20 or 30A breaker for Enphase Combiner receiving 16 M215 Microinverters

    Uffda! Realizing now that there is a 25A Eaton BR breaker that would serve this direct purpose.

    20 or 30A breaker for Enphase Combiner receiving 16 M215 Microinverters

    I am centerfeeding a string of 16 M215 Enphase Miroinverters (so the junction box is in the middle of 2 sets of 8 MI). Altogether this would be 16 MI that would land on the breaker in the Enphase Combiner box and I am wondering if this should be 20A or 30A. The current per MI is 0.9 so 16* 0.9...

    # of CCC in conduit / Ampacity check of THWN-2 in 4 CCC 18" underground PVC conduit

    Correct the THWN-2 is actually 90C rated wire - however the breakers attached are rated at 75C
