I understand the general idea "electric hot water heaters" are inefficient and also often require expensive wire upgrades and maybe larger breakers, or even special 240v circuits. People usually learn about it and get disillusioned. I've watched more youtube van/rv/camper/offgrid videos than I...

I want to find a way to use two old home theater subwoofers with failed amplifier boards. I also have two Jensen XDA92rb car audio amps which run on a typical 12v car battery, around 240w rms @4ohm (600w peak) which matches well with the subwoofers. I have a 24v 200ah lifepo4 battery charged...

Hello, I needed a way to charge various batteries and decided to go with the newer ISDT charger similar to the q8 called the ISDT Air8 (20A, 500w, 8s). It also came with two of the Battgo plugins which was part of the reason for my choice over the q8. Of course, you just plug them in and the...

Any time I find a decent ground mount idea I find something to dismantle the idea, often it becomes quite expensive. I was contemplating a solar pergola to shade my porch and back of my house (southern facing, yeah). I'm the guy who would live in a geodesic dome but I've read enough to...

I found a local supply for a few of these panels but when I searched reviews I find only the same videos I watched years ago. Stion 135 with a frame is the model. I realize the company is gone. Can anyone comment on expected vs real solar output? Longevity? Issues? Thanks,

I have around 2.5kw of solar (off the grid) and I'm switching to a very cheap overnight grid rate ($0.02 or so most of the time at night) so using electricity for heat. After searching and looking at the overall market, I just discovered these small 110v heat pumps for smaller swimming pools...

Just a little background. I have been using around 5.2kw of 32650 cells premade into 20 cell packs which came pre-spot welded with nickel strips (battery hookup) and terminating in ring terminals and 1/4in screws and bolts. Works fine. Then I just bought another 20kw or so of additional 32650...

There is a local supplier of some damaged 235w 60 cell panels. The "damage" seems to be mostly the broken front glass. MC4 connectors seem intact. I will be able to visually inspect each one, and I'm sure I'll at least check voltage, etc. If someone has a great checklist of things to look for...
