I always thought spending a couple hundred dollars for a day's rental of a man lift would do the trick nicely. That, or build a basic crane with 2x4s. Lots of out of the box ideas. A basic ramp made with 2x4s works well too.

I've thought about buying one of those "400W" wind turbines from Amazon and designing/fabricating some larger blades for it, potentially 3d printed with wood spars (or similar). I would imagine the "400W" rating is reasonable for the generator/wiring and wishful thinking for the power able to be...

I don't recall if it was with rtl_433 or rtlamr, but using a SDR and listening to the broadcasts for my own smart meter (ITRON) showed a field that was named something along the lines of BackfeedPower and last I saw it read 44. This was 1-2 years ago. Trying to figure out which it was. I haven't...

100% this. I like to point out to rabid green people these three things: there are constant news headlines about "more wind/solar installed in [previous year] than any other year!" there are constant news headlines about how the price of new wind/solar is the lowest it's ever been their...

any of you looked at repurposing a pool heat pump to heat your house (either via water or air)? just started a thread here - https://diysolarforum.com/threads/pool-heat-pumps.77234/ https://www.amazon.com/villastar-Inground-Heaters-gallons-Electric/dp/B0CGQSBTP7/

Anyone using pool heat pumps to either heat water for heating house or cooling water to spit out hot air in the house? The prices on some of these are pretty low for a water-air heat pump. Example (there are many in the $600-$1000 range for nominal nameplate heat output)...

NWS does provide an hour-by-hour cloud cover forecast. You can get this data in xml format as well. Not going to help if forecasting is particularly difficult for your area (I am Front Range, CO, and the mountain wave clouds or lack of are notoriously difficult to forecast on certain days). 3rd...

sorry, guess I misunderstood the ask

Get a used APC UPS in the 1500W range. Lots of people sell for cheap because the lead-acid batteries go bad after like 3 years. These use 24V batteries. They have minimal idle draw. Then hook up as much battery as necessary. Then either plug into wall or if you still want double conversion, get...

Unless you had the panels actually hooked up to a load and 2x meters (one for voltage, the other for current), you measured the open circuit voltage (VOC), and the short circuit amperage (Isc). Panels never produce at the power represented by VOC x Isc. There is a curve. MPPT (maximum power...

Do some quick math on your options here regarding your unusual phase situation: buy a new fridge that's single phase buy an inverter (or 3x) that can output the correct phases You may find it cheaper to get a new fridge and 1x standard single phase inverter

I know this thread is about dumb heating elements and water pumps for concrete heating but you should probably also consider mini split heat pumps. In heat mode, they run like an AC in reverse (cool outside, heat inside). They are commonly 3x more efficient per watt-hour than pure resistive...

Lots of wall to hang solar thermal collectors on! Nice shop/building!

No way they're paying residential rates. $2.6 / therm is #1 a lot, and #2, $26/MCF. Natural gas traditionally is priced in million BTU increments via futures and whatnot (henry hub - contract is for 10,000 MMBTU -...

Build some solar thermal water heating stuff. HD says 0000 is $1200 for 500 feet. I'm assuming need 3x that due to L1, L2, neutral. + some extra for ground (not as big a wire). That's $4000 you could use to do solar thermal heating...
