Re: [RE-wrenches] DC-DC converter question

Allen, John, et al, Aren't DC-DC converters a mainstay of Solar Converters, Inc. product line? Just to toss another manufacturer into the mix. Stay warm, stay safe, Bill Loesch Solar 1 - Saint Louis Solar 314 631 1094 -From: "John Blittersdorf" To:

Re: [RE-wrenches] GENERAC EcoGen 6kw problem

Wrenches, Kudos to Ray for "getting down to basics" May I suggest that my own observations are that a comprehensive visual inspection of the affected component can be the most valuable time spent diagnosing a problem. Recently I was called in after five other techs had "looked" at the power vent

Re: [RE-wrenches] Electric Water kWh/ person

Ray, Chris, et al, Both Paloma (185,500 BTU/h) and Bosch (117,000 BTU/h) manufactured natural draft heaters that used zero electric, just like common tanks. Because the majority of these units used a standing pilot, they were castigated by the energy bureaucrat folks in favor of something that use

Re: [RE-wrenches] Electrolyte Dilution vs Voltage

Steve, Thanks very much for the IR image and the explanation and one possible remedy. I had (mistakenly) always considered once the plates were exposed to air there was always irreparable damage. What camera are you using? Thanks again, Bill Loesch314 631 1094 ---

Re: [RE-wrenches] battery temp sensors for older Trace/Xantrex inverters

Fellow wrenches, Am I missing something? Other than the way the sensor connects to the inverter/CC/??? is this not simply a thermistor/other discrete component with the appropriate output? Yes, it is potted for preservation in the potentially acid vapor environment, and provided with glue when the

Re: [RE-wrenches] Trackers

Chris,I thought since solar PV prices have come down (understatement), is it not more cost effective to buy more modules than a tracker? Are there scenarios that the above would not ring true? (As I remember, off grid water pumping for livestock ponds may still be an exception as also, limited spac

[RE-wrenches] Digital Refractometers

Hi William, The old school optical (analog) version is too time consuming for your needs? If not Misco makes two models oC or oF The oF model is 7084VP. The actual manufacturing of the unit is done by Reichert. Reichert makes multiple digital refractometers, hopefully of the same quality as the Mis

Re: [RE-wrenches] New Washer - Old Inverter

Lou, You are getting great advice from the list. Yesterday's sinewave inverter is not today's sinewave inverter. The washers are improved, too, likely using an ECM motor today. If the washer is the only holdout, have you considered a dedicated high quality, high surge, 1800 watt inverter for just t

Re: [RE-wrenches] Hurricane damage to solar arrays

Jason, Thanks for the preliminary failure analysis of the latest hurricane damage. Do you have any photos which shows the bent mounting plates for the micros? Wouldn't that be an indication of the force applied before something gave up? Good call to get new micros when the leads and their attachmen

Re: [RE-wrenches] Outdoor rated insulation covering for Solar Water Heating Systems

Chris, The fitted covers certainly provide a more finished appearance. One of my customers painted the insulation (w/o fitted covers) with latex paint and after 30+ years the insulation was still quite flexible. My take away was simply that eliminating the sun (UV) effects paid off big time. As I

Re: [RE-wrenches] Outdoor rated insulation covering for Solar Water Heating Systems

Hi Chris, Your question certainly generated a number of responses. While the field applied covering I mentioned certainly peeled off and had the consistency of latex paint, I did _not_ perform an analysis. There is outdoor latex paint which should have UV inhibitors, so perhaps it really was latex.
