[RE-wrenches] The legal and financial fallout from LG ESS inability to communicate RMA replacement timelines

I wanted to let my professional peers know the disappointment I am having with LG ESS. The inability of LG to communicate warranty replacement timeline has resulted in legal action against me the installer. Maybe my alert here might save some of you similar angst. As much as I'd like to push b

[RE-wrenches] Remote AC well pump

Hi all, I have done no remote well pump system design. I have a potential client looking for help driving a remote AC deep well pump with PV. My first reaction is too say in order to do that, they will need an inverter and batteries as well as PV and charge controller. But it occurred to me to ask

[RE-wrenches] Lighter tubing?

Hey all! I am proposing a [20] module, 35˚ tilt up array mounted on a flat roof in snow country - Central Idaho. Its in town, trees behind & off to the side a ways. The SnapnRack design calls for [21] Pieces of 1 ½” x 21’ sched 40 pipe +/-. I am trying to understand the need for sched 40 pipe

Re: [RE-wrenches] Lighter tubing?

We did a setup with the Snap N Rack rack on a roof once.  We just used the recommended galvanized SCH 40.  Its basically a readily available product.  I would be careful with other types of steel tubing: make sure it will fit the fittings.  We actually retrofitted a Snap N Rack to some existing

Re: [RE-wrenches] Remote AC well pump

Hi Howie, There are many options for this equipment now. If the well pump motor is already installed, it may limit your options. If it hasn't, then there are a lot of good solar pumps available. Grundfos SQ Flex is solid from our experience. There are also drives that can take high voltage sol

Re: [RE-wrenches] Remote AC well pump

It all comes down to how deep the well is, and how much water you need to pump.  For lower head, lower flow rates, just go with the SQF line.  If you need more water, then start looking into the other options. Just as with off grid homes, you need to carefully define the parameters:  depth to

Re: [RE-wrenches] Remote AC well pump

Thanks Jerry, that is what I would certainly suggest first, but I was just curious if there is a way to drive an AC pump with just PV before I suggest pulling the pump. Howie Howie Michaelson Sun Catcher NABCEP Certified Solar PV Installer™ Solar Electric & Heat Pumps Systems Sales & Service 802-2

Re: [RE-wrenches] Remote AC well pump

Hi Howie Yes ac PV direct is off the shelf these days. But typically with 3phase pumps. Tons of variables, how about some specifics as to depth, gpd required, gpm requested, well production, pumped height, location for starters. Jay Peltz power > On Jul 26, 2021, at 7:14 PM, Jerry Shafer
