Allan, I have used the Mean-well converters several times and have had good luck. My other choice would be an Iota but definitely more expensive. John Blittersdorf Rob Stubbins Solar On Tue, Dec 19, 2017 at 1:29 AM Sindelar Solar wrote: > Wrenches, > The time has come to upgrade a longtime c

[RE-wrenches] Concrete Tile Roof Solar Installation - Oregon - Engineering requirements

2017-12-19 Thread Kirpal
Hi Folks! We don't get many jobs installing solar on concrete tile roofsthere aren't many around here. In Oregon we are allowed to do an engineer-less installation on metal and comp roofs when the array is flush mounted to the roof. Concrete tile roofs don't fit into this scenario. My engin

I have a Postive grounded SunPower System with two private labeled SMA 6000 watt Inverters installed in 2009 and want to use SolarEdge 7600 and their optimizers at least for half the array ? Modules are SunPower 210 watt modules - how do I work this out ? GatorTom PS : 48 modules ground mounted i

Kirpal: It seems to me this is a matter of defining "Flush-mount." I would call any installation where-in the panels are within the perimeter of the roof, parallel with the surface and not more than 10 or so inches from the surface of the roofing material a flush-mount. A proper tile roof instal

I’ve used Iota or Powermax over the years for this exact situation with great reliability. Maybe today there are less expensive options? Jay Peltz power. > On Dec 19, 2017, at 6:15 AM, Roy Butler wrote: > > FYI.It appears that Solar Converters may be out of business. > > Roy Butler >

Fellow Wrenches Some time back we were doing concrete tile install all the time. We approched it somewhat different. We removed all the tiles on the area for the array, preped the area and installed installed comp with quick mount afterwords we reinstalled the tile around the modules. The profile w

We have just received some product from solar converters. I don't believe they are out of business. We use their 48-12V converters frequently for situations like this. Lower idle loads and higher efficiency than using a 12V power supply from Iota or others. Though have had a couple failures o

Kirpal, Specialized structural engineering really shouldn't be required for a standard flush mount tile project. If it is, I have a few PE structural contacts who typically do this kind of work for closer to $200, contact me off list if you're interested. Secondly, I agree with William to be wear

Tom - I was just asking a SunPower rep about this. My understanding is that a PID (Potential Induced Degredation) discharge device is required to use SunPower positively grounded modules with a transformerless inverter. These are expensive and not listed for the US market. Long story short, I don't
