Re: [RE-wrenches] SI6048s won't charge from generator
Jerry: The gen is powering the loads through a bypass breaker so we can't be stopping and starting it. We did simulate an inverter start by initiating a start signal and immediately closing the gen feed breaker. This eliminated a sync error but did not allow the gen to charge.

Isis you use the inverter to turn on the genny or did you just start it up because it may not connect if it did not request it that has happened to my customers. Go into the gen menu and try from there. On May 4, 2014 7:25 PM, William Miller will...@millersolar.com wrote: Jerry: Your answer was pretty vague. What kind of mid-wire or programming error?

There is no phone service so using tech support is cumbersome. Has anyone experienced this problem before? Thanks!

[RE-wrenches] Solar Edge Experience?
Hi Wrenches, I have been watching Solar Edge for a while now and am curious if other wrenches have been using their product and what they think about it. I’m generally hesitant to adopt new technology until it has a good track record but I have to admit that I’m seeing some serious benefits in the Solar Edge system – long strings, module level tracking and monitoring, design flexibility, etc. Can folks who have tried their product let me know what you think and if you’ve had any failures? http://www.solaredge.us/groups/us/inverter/single-phase-solar-inverter Best, August Luminalt ___ List sponsored by Home Power magazine List Address: RE-wrenches@lists.re-wrenches.org Change email address settings: http://lists.re-wrenches.org/options.cgi/re-wrenches-re-wrenches.org List-Archive: http://lists.re-wrenches.org/pipermail/re-wrenches-re-wrenches.org List rules etiquette: www.re-wrenches.org/etiquette.htm Check out participant bios: www.members.re-wrenches.org

Wrenches, I'm am in the initial phases of design for a commercial system in Honolulu and I'm planning on 1000v on the DC side and I want to know if anyone has had any issues with the AHJ on going over 600v. Any advise on designing or installing in Hawaii is appreciated.

Re: [RE-wrenches] Solar Edge Experience?
Hi Bill, That was my take up until recently. However, we’ve had lots of Enphase failures with M190s and M210s (to Enphase’s credit, no failures yet with M215s and M250s) so I’m hesitant to put more and more micros up on the roof. Plus, the price starts to beat micros around a system size of 4+ kW. We’re seeing a lot of competitors offer Solar Edge in the Bay Area including Solar City so there must be some good reasons to use them. In my mind, reliability is of utmost importance and I don’t have any firsthand knowledge on how the Solar Edge systems are working. I think they’ve only been in the US for about 3 years.

Re: [RE-wrenches] Solar Edge Experience?
No trunk cable is bonus. Working with regular PV cable is easier on stocking materials. Safe working voltage is real bonus and makes testing during installation reasonable. Strings over 12 is bonus. Sometimes, 16, 18+ makes sense physically. Now it can make sense electrically. With different solar exposures. Still needing to use metal conduit inside is sometimes a hassle, but MC cable makes it doable. No way to test communication with optimizer until DC voltage is applied. This means if you have a DOA optimizer that reads correct voltage, you are removing modules to get to an optimizer. That is a drag. Support is pretty good. The new 7kw inverter matched to 40a OCP to max out residential 200A panel backfed breaker sounds good.

Re: [RE-wrenches] Solar Edge Experience?
Augustwe have a half dozen systems out thereThey are all producing with high efficiency and no failures yetI think one advantage they have over micro's is that your wire runs are made using 350VDC and so you can get up to 25 modules or ~5200 watts per string ( which ever you hit first)where as with Enphase you are limited to 16 inverters. Addtionally they have 300 watt optimizers which i like for the bigger 60 cell modules. This means no clipping. That said Enphase has some arguements why clipping isn't so bad. We have found there to be more labor on a Solar Edge installation as there is both a central inverter and a rooftop box that needs installed. All the communications to their web site has been working perfectly so far. As does the communication between the inverters and optimizers. Make sure to get the proper module connectors that match your solar panels. Good luck.
