Re: [RE-wrenches] Removing paint from solar modules

Hi Mac, I second the isopropyl alcohol (diluted), a soft cloth, and razor blade if needed. Magic erasers would probably work too, but I believe they are made from very hard microscopic crystals. Good luck. Garrison Riegel Celestar Solar LLC > On Apr 15, 2022, at 9:45 AM, Dana Orzel via RE-

Re: [RE-wrenches] Has anyone ever had one of his customers get a note from SolarEdge like this one?

Hi Scot, Do you know your local SolarEdge rep? If so maybe they can help. I have been having ongoing issues with SE “revenue grade meters” reporting inaccurate data for months, and my rep has been a good advocate. She is pretty new so doesn’t have a lot of clout, but to her credit has helped ge

Re: [RE-wrenches] Utility transformer limitations

Hi William,One possible path forward would be to ask the utility co what AC inverter capacity would be allowed. Maybe the solution would be to unplug a micro or two if you are just over the limit. Even better, maybe they would allow you set an export limit on the micros you have installed.I had a r

Re: [RE-wrenches] Truss finder

Re: [RE-wrenches] Snapnrack end caps

Hi Drake, I can confirm. The design could be improved. I’ve noticed that end caps on rails that are flush or a fraction of an inch shorter than the panel frame lose the end caps at a higher rate than when the rail sticks past the module frame. My guess is that module movement from expansion/c

Re: [RE-wrenches] SolarEdge Battery question

Hi Jason,On a recent install 2 of 3 new batteries had a low SOE and failed the self test. This made sense as part of the self test is discharging the battery, which you wouldn’t want to do if the batteries are depleted. Anyway, the low SOE batteries also had trouble “associating” with the inverter

Re: [RE-wrenches] Panel installation in snow country 0.02

Hi Howie,I have found one scenario where heat tape can help with snow on solar.As we know, solar panels warm up in the sun and melt snow even when ambient temperatures are below freezing. The water from this melting snow drips off the array and slush/snow can slide off the panels.On a cold day, in
