Re: [RE-wrenches] Water system with Grundfos SQFlex

Brad,For hand installation, especially with lower flow rates, my go-to solution, mentored to me by Windy Dankoff, was SDR9 high-pressure (140 psi max if I’m remembering correctly) flexible polyethylene pipe with bronze SDR9 compression couplers and connectors to MPT. They all used a stainless

Re: [RE-wrenches] TPM Search

In my experience, trackers have never made sense in off grid residential applications. In general terms, an expensive dual-axis Wattsun tracker offers a ~35% potential increase in daily solar gain around the summer solstice, and only a 10-15% gain in winter, due to seasonal sunpath variation. Any

Re: [RE-wrenches] Conergy solar module issues

Chris, as an issue of concern for many on this list, don’t ask for replies to issues of this type off list, but rather here. In fashion typical of the solar coaster, Conergy was a Major Supplier for a few years before predictably imploding. Quite a few of us have installed systems with Conergy

Re: [RE-wrenches] Home grid stacked battery heating

I did this modification to a 16kW Blue Ion LiFP bank during installation, following this guide, Darryl. Blue Planet had sent me this. Shortly after initial installation a plumber had installed an electric space heater in an unheated space with water pipes, which of course soon drained the

Re: [RE-wrenches] Magnum problem

Ron,You didn’t say whether the 4448 is a PAE or the original AE; at 4,400 rated watts, I’m assuming that it’s a PAE, meaning split-phase 240. Your 2,000W Honda has a 120V output, and I suspect that the 3,800W Champion does too. Have you taken this into consideration?Many years ago, one of the

Re: [RE-wrenches] Old Solar Modules

The Photowatt is French. Early 80s most likely. Windy Dankoff imported them for a few years, late 70s - early 80s. They’re remarkable modules. I had (before I retired) several clients still using them. Every one is still putting out at or close to rated output, 40 years later. The only problem

Re: [RE-wrenches] Magnum Inverters

One caution, Jeremy. The EVOs that I used are only available in 120V input and output, and Magnum PAEs are split phase 120/240. Allan > On Jul 23, 2022, at 3:34 PM, Jeremy Rodriguez via RE-wrenches > wrote: > >  We’ve ordered one to try since we cannot get the PAEs. > I hope Magnum can
