Re: [RE-wrenches] Unirac SolarMount rail caps

Haven't looked at how different the profiles are, but IronRidge's light rail is fairly similar and they make black plastic end caps that you might be able to make work... Howie Michaelson NABCEP Certified PV Installer Catamount Solar www.catamountsolar.com 802.272.0004 Sent from my cellphone

Re: [RE-wrenches] Murphy Gen Control Oopsies

Turns out to be a grounding issue.. the solenoid uses a common ground wire for suck in and run. It also shares a circuit with the starter solenoid. so when it sees no/ bad ground, the next best path is thru the starter solenoid.. which can energize the start circuit (sorta). They told us similar st

Dana, We were looking for a square cap, but I think I remember some rectangular ones? Their site isn't very navigable, so maybe a call to C.S.? [Description: Description: Description: NYLElogo] Mark Richardson mrichard...@newyorklightenergy.com From: re-

Re: [RE-wrenches] Unirac SolarMount rail caps

Thanks for the thoughts, everyone. I suggested filing the ends with grey caulk, but the homeowner didn't like that idea. I think I'm leaning toward finding some aluminum channel or angle to fit over the end and either glue or screw it on. Mark - Did you find rectangular vinyl caps? I checked out

Thanks for the responses, all. Matt, I am coming up short with an internet search for 'Seltrol 112' and 'Seltrol 112 inhibitor.' Do you have a data sheet and/or a lead where to buy it and find out more? Thanks, -Nathan -- Nathan J. Stumpff - Arctic Sun, LLC NABCEP Certified PV Installer #09120

All SunPower modules with NE in the model number are specifically listed to be positive or negative ground or ungrounded with transformerless inverters. Thanks, Will __ Will White Regional Field Operations Ma

Re: [RE-wrenches] Enphase M210-84-208-S12 Inverters Available?

HI Dave, You are correct. The Enphase Microinverters bond the DC positive to ground. This is not an issue. Most modules will operate normally with either; no ground bond, the DC negative bonded, or the DC positive bonded. SunPower modules are the exception, with a requirement for being positiv

Re: [RE-wrenches] Unirac SolarMount rail caps

I have put expanding foam inside the ends to prevent insects. As for the finished look... never had the problem. We just do a clean cut with a sharp blade and keep the length outside the module to a minimum. Jason Szumlanski Fafco Solar On Fri, Aug 10, 2012 at 4:12 PM, Dana Brandt wrote: > We

Re: [RE-wrenches] Thermal storage water stabilizer

Distilled water is distilled water, not hot water. Distilled water comes from water boiled into a gas, then the gas is distilled by passing through a cooling coil or heat exchanger, and when this gas turns back to a liquid it is distilled water. Commercial water distilling systems use either glas

The SnapNRack ground mount rail system has end caps, we just installed them on a project and they look great. On Mon, Aug 13, 2012 at 9:24 AM, Mark Richardson < mrichard...@newyorklightenergy.com> wrote: > We had to find end caps for a ground mount that was used as part of an > environmental lea

We have used Seltrol 112 as an inhibitor in large unpressurized drainback systems based on a recommendation from Holocene. I have previously worked on large unpressurized systems from other installers and not seen any issues with their tap water-only systems (though I have seen multiple issues wit

Re: [RE-wrenches] Thermal storage water stabilizer

I've wondered about this as well with our unpressurized drainback systems. My HVAC supplier had told me that once you heat the water above 165 or so, that you basically have distilled it. Not sure. I thought you would need to boil it. Though we have had no issues with corrosion as we have had s

Re: [RE-wrenches] Thermal storage water stabilizer

Nathan, We've done a couple of systems with large unpressurized tanks (STSS). They work well but there are a couple of things you need to pay attention to. We use tap water to fill the tank which works fine but you have to make sure the PH of the water is in the correct range. I can't rememb

Re: [RE-wrenches] Murphy Gen Control Oopsies

Silly question, but have you talked to the manufacturer? http://www.fwmurphy.com/ I can't see how it would be an off-grid issue. The voltage on the solenoids can only be 12V, so it's not an overvoltage issue. If the controllers were faulty in the way you detail, that would be happening with every g
