Re: [RE-wrenches] Sunpower connectors

Evan, I am not sure if this is the same issue, but I have seen a lot of arc fault issues with the E20-327 modules paired with SMA inverters. Every system that we have done repairs on have had the Yukita junction boxes, and there were a handful of failed solder joints on the diodes in the junction b

Or a different way to actively vent a battery box? I prefer to not have a DC draw that does not go through the inverter if possible. Cheers, Dave -- [image: Logo] <https://www.sungineersolar.com/> Dave Tedeyan, P.E. Owner | Sungineer Solar p: he | him | his a: 1653 Slaterville Rd. | Ithaca,

It was about a month ago that I tried reaching out and was getting that weird phone message that does not allow you to get anywhere.

Re: [RE-wrenches] UL3741

Hi Lou, It looks like Ironridge with the Midnite's MNSSR-600S-SS and some Solis Inverters (or Tesla) are compatible. But that is all I know of off the top of my head. https://www.ironridge.com/2024/02/27/flush-mount-systems-listed-to-ul-3741/ I have not actually pursued this yet, but would be cur

Re: [RE-wrenches] 208V residential service

Hi all, Unfortunately this sounds like it is occasionally done on purpose by the utility, and I don't have much leverage to get them to change it. Good to know. I am trying to get details from them though about whether they would drop in a 240V transformer and what the cost will be. In the meanti

Re: [RE-wrenches] Overpowered mppt landing in a SMA-41?

Hi Bill, Those SMA inverters can handle a max Isc of 18A. Check your module datasheet, but I would assume that you would be under this limit. I've had strings with an Imp of 11-12A and the inverter just adjusts where it is on the MPPT curve to keep the current to under 10A. So there is a little bi

Re: [RE-wrenches] All-In-Ones / Sol-Ark fail

Yikes! I cannot speak to the AIO's in general. However, I do still always install some sort of inverter bypass in battery based systems. Then in case of a failure like this you can at least continue to power the house off the generator as long as someone is there to throw the switch. Cheers, Dave

Hi All, I talked to Enphase recently about this. They will be providing warranty support at least for Sunpower's microinverters. They do not know how long Sunpower's monitoring will continue to work. But they have figured out a way to use their Gateway to monitor Sunpower's microinverters, even th

u are adding Enphase to an existing Sunpower system, you might be able to get one of the specially programmed Gateways from the beginning. Those will be able to monitor both the Enphase and the Sunpower equipment. Cheers, Dave On Fri, Sep 27, 2024 at 8:05 PM Dave Tedeyan wrote: > Hi August, >
