Sorry but I'd trust a handyman here about as much a chocolate kettle, the majority of buildings here have ground to earth just the un-handymen don't understand what a ground even means let alone how it's attached. See the image below, this is how the majority of roofs are connected to the beams...

Sourcing copper above 12mm diameter might be an issue, where stainless is readily available in any size for mainly manufacturing gates.

They look to be old poly stock you can get 250w versions on Lazada for around the 2,000 PHP mark

If you have one of the original undamaged connections and a Vernier/micrometer some measurements of the connection would be interesting, the plastic likely gives a tight connection but how are the tolerances on the actual contact surfaces. Edit: Or better yet measure multiple from your stock to...

I'm always curious as to why us as Westerners seems to congregate in the most inhospitable parts of the world many Americans live on fault lines, near super volcanoes and hurricane highways. Britain is a perfect climate for frogs and almost nothing else, yet both the US and UK seem to be fine...

I distinctly remember copying the thread to my clipboard but sadly I'm an idiot and must not have posted it sorry Ouch it's overcast and miserable here I would have put it on par with Wales but we still seem to get around 2kwh per day off 760w of panels. I'm sold on getting a system to power...

Surely she will see you trying to hulk those panels up the stairs.

Is that °Celsius? Edit: Ignore me I can't read or spell

Of course I'm assuming op hasn't stated otherwise, I'm British and we used to use doubled conductors in every household two 20 amp conductors fused at 32amps feed the sockets it was 30 years ago since I did any training so I don't remember the science but it was drummed into us that using two...

Sorry I stand corrected I had no idea there was a difference as most knauf insulation is classed as glass mineral also and basalt can be considered volcanic glass. so polyester has less than half the r-value of rockwool as rockwool is considered 33% higher than normal fibreglass.

I have a epever mppt controller that was fairly easy to set up with esphome and is kinda officially supported but there are many many more out there it's just a matter of finding them on GitHub. I did a quick search for hqst but couldn't even find a breakdown of the modbus registers so you...

Just worked out the pricing and I'm saving $500 by using 200ah Lifepo4 cells compared to 160ah FLA and that's just a single 48v bank so I might still be better off even with the cost of the cooling. I doubt I'll start the project till maybe the end of the year or the start of 2025 but at least...

A picture would be great! Everyone suggesting stoves and such is fine but is it integrated grate or free standing, does the house have a hot water cylinder that could benefit from a stove with a back boiler? If it's a freestanding fireplace( box in the wall with a flue) and there is a hot water...

Sad thing is I could have shipped you anything 12 months ago even complete burners if I'm remembering correctly the riello`s used danfoss oil pumps that had a solenoid fitted and would be powered by the squirrel cage fan.

Thailand it must be torture for you.

I understand the need for distance when placing rods what I'm saying is there should never be an exception to your resistance. once you meet your desired resistance rating you can then test for loop impedance to work out how big your cable size needs to be, at least that's how I was taught.

Power factor is rarely shown in documentation but it's a very good point that I haven't even considered when sizing the inverter for my home, I have power factors on all my meters around the house maybe I should implement some code to show me accurate figures.

One thing you might be not accounting for is the inverters demands, not sure about every brand but the ones I've come across don't display the wattage the inverter uses in their software. My SRNE is 2kw but uses 30W give or take on its own which might not seem alot but at low loads can make the...

First thing would be to burn your isp provided router(semi joking). What are your needs? How much are you willing to spend? How far deep down the rabbit hole are you willing to go? Those are the main questions you need to ask yourself If your only talking about a small network and you just want...

Buy American, Buy Molex

thanks for the speedy replies guys. so it hovering between 80-85% is standard, it was a new data set i added myself out of curiosity as the inverter had nothing about it other than the quoted 95% on their website,cheers for setting my mind at ease.

Quicker reaction speeds and more accuracy for automations currently I'm limited to 20 second polling so a load may take 20 seconds to switch off but during that data input there may just be a passing cloud so a load might switch off for no reason. More data sets more accuracy better I can set...

Had a slightly heated debate with a German electrician on this and she pointed out screw terminals loosen over time and connections like this have been available in Germany for almost 40 years and haven't needed regular maintenance. Oh now I feel slightly bad for slagging off the installer but...

Many homes in Turkey and Greece just use old compressor tanks painted black very similar to this https://www.byexample.net/projects/current/batch_collector/

That has a dedicated wall wart no? Guess it would have to as SSDs fail on usb power, spinning drives have no hope. I have a pile of pi's here that got replaced by a single commercial server, I keep thinking of novel uses for them like a robotic lawnmower but I'm yet to actually do anything with...

Personally I wouldn't even use a copper washer unless all the surfaces were copper especially on something I'm supposed to kinda do once and forget(might be an incoming idiot moment) surely galvanic corrosion would start to be an issue if the contacts were zinc plated or worse steel if your...

Be sure to dip your rod in wax first before testing, most hyperbaric welding is in the 300-400amp range maybe at the amperages were using the arc wouldn't sustain but I'd be inclined to think the water will just vaporise but wetting the surrounding area might prevent the arc from spreading.

Lol we went from french press to percolator to instant e-waste coffee

I have a few pi4b and pi400 and all have corrupted with influx+graphana on official pi psu's and 100w gan chargers can't even get my touchscreen to work on the 400 because I have to separately power it which seems to disable the touch input. Don't get me wrong pi's are great but after all the...

The record time to get from the UK's southern most tip to northern most point is less than 10 hours, you can literally fit the whole of Britain into Texas but my previous home in Wales was 500 years old.

See the house burned down thread no signs of his steel battery queen boxes.

Sorry OCD, I tend to self level and epoxy all my workshop floors, i had a flagstone floor in the basement of my previous home although it was "pretty" I'd made me sick looking at it.

Essentially the same thing but Japanese, confused is the pump on an independent motor? What's wrong with that one?

From what I can see from the esp code it seems to be 5s intervals which is still alot better than I'm currently getting not real time but that's still 4 data sets in the time I usually get 1

Anyway back to topic Meme: from the Greek mimema, meaning something that has been “imitated.”

If there's a option for misinformation and say 4 or more press it the post could be striked out or have a warning "this is BS"

With sd cards and usb sticks it's more to do with the limitations of the nand chip, you might currently have better luck with usb but I would say given time that's going to fail also they just aren't designed for that many writes and will slowly corrupt/die. If you want to keep your data id...

Send me some details on the pump that's fitted and remove the burner jet and give me the jet diameter and angle(should be stamped in the brass) and I'll take a look

What I mean is peak power on typical meters isn't actually peak as it accounts for power factor most of the high current draw items in my home are "high efficiency" so likely have a lower power factor. When an inverter specs show a peak power rating that's going off a pf of 1.0 when in reality...

Negative and positive would need to be connected, ground/earth should be connected to a grounding/earthing rod not the battery. But going off your name maybe a buried rod wouldn't be ideal if your setup is on a moving vehicle

This is why I'm thinking of forming them myself that way I can keep any connections above ground, I don't have a Tig welder on hand here and I'm unsure of adverse effects of oil on solder and even how well you could get it to adhere to stainless, so likely I'd go down the high pressure flange...

Bonus that you still have to pay for isn't really bonus, a few bags of self leveling compound would have fixed the unsightly gaps under the skirting. If your flipping a house it's fair enough but if your aim is to spend the rest of your life in a property things that aren't perfect tend to...

Also if your system is to be fitted to a van be careful to make sure your panels aren't grounded they can fry electronics in the van, do a Google search there's plenty of forum posts and literature about best practices when installing on vans.

No idea what's going on here but it's not series This is parallel and would only give you 12v I believe

The sunsynk card can likely be used, you still have to input your own entities but it's a pretty neat card for a quick overview https://slipx06.github.io/sunsynk-power-flow-card/index.html

Because that's boring....no in honesty if the theory works it shouldn't really need any maintenance and if the ground source cooling works extremely efficient, I could also put in redundancy pumps for any emergencies and as far as operating it's likely going to be connected to the house via esp...

Staubli are indeed German and sadly @Supervstech china do indeed make exact copies @jdurban if you can't be sure where the connectors are being shipped from I can recommend molex mc4 atleast from what I've seen the Chinese aren't making copies of those yet and they are still made to a high standard.

You could try to inject dielectric into a mated connector before tightening the gland on each end but it seems like it would be messy and a pita if you ever needed to disconnect and reconnect later.

As wpns stated and going off your 2nd attachment(mounting plan) the rails should be mounted perpendicular to your rafters then the panels mounted to the rails, seems the plan indicates 8 lengths of rails with 7 mounting points to rafters per rail.

This guy has been playing with lora for years now on YouTube check out his videos. Ended up using a large WiFi network myself but I was only dealing with a few km².
