Hi Wrenches. If you have any questions or concerns, please contact me off-list. Several folks have asked me about the RE-Markets list that I set up, and run in conjunction with Bill Roush. Here is what it is for: The RE-Markets list was set up specifically for discussing marketing and similar

HI Brad, I was just about to hit send on those exact wattages, yes completely agree. As a sort of joke, the self discharge of the batteries is probably more than what she could make in a day. Jay > On Mar 16, 2023, at 4:29 PM, Bradley Bassett via RE-wrenches > wrote: > > I tried this

I tried this back in the 1970's with an exercise bike and a high efficiency generator (still have this if anyone wants it). If I pushed hard I could get it up to 200W, but only sustain about 100W. The only time I used it is when my battery was depleted and I wanted to watch TV. I had a 12VDC 5" B

As I recall from pushing the "wayback" button, Backwoods and Real Goods used to sell something like that in the 90s.  I would only see a pyschological benefit, based on the system size. I recall that the charge rate was less than 50 watts, so its really not going to be worth wiring into the

Bicycle charging her L16 battery bank would be fine waste of effort. In good shape she might be able to make 200 watts for some part of an hour before being tired. Even Lance Armstrong in his peak probably wouldn't be producing multiple kWh per day. My $0.02 worth, -James Jefferson Jarvis APRS

Wrenches/Hilton Home run connections, confirm brand, had issue where it needed more volts to overcome the poor connections. You will need to be on site with at least two techs and check each homerun first but l have had module to module issues. I have also had internal issues at the Jbox some

Hilton, Can you give more details about the inverter? And when the DC was reading 0 volts, did you try turning off the disconnect at the array to see if isolating it from the inverter, it would show voltage? Howie *Howie Michaelson**Sun Catcher* *NABCEP Certified Solar PV Installer™* *Solar

In my experience, if the Trina modules have the TS4 connectors on them and are mated to an MC4 connector they tend to have issues. Bryan -Original Message- From: RE-wrenches [mailto:re-wrenches-boun...@lists.re-wrenches.org] On Behalf Of Hilton Dier via RE-wrenches Sent: Thursday,

Hello Wrenches Here’s a classic problem for you. I installed an array of 11 Trina 380s on a ground mount, commissioned January 6 of this year. It worked fine for a while, but in the last week it has had an intermittent power problem. For example, this morning it was putting out zero watts at
