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 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...
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...
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.
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.
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

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...
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...
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...
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...
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.
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...
That seems to be the pzem017 which sadly doesn't report current direction I've looked at the other models but I'm currently looking at the junctek kg-f (Hope it's not junktech) it seems to be able to show directional flow and I should be able to hack the rs485 output. It's just a test idea for...
Ahh right I guess this is where your confused type-b GFCI devices weren't a mandate in the UK until recently and still only on new installations so as far as DC the ground is your primary protection not the GFCI. More Worrying is that unless it's a new install many people in the UK still don't...
Depends on your tariff, some people are only allowed 2.5 Kw average, 7.5kw peak
You are only allowed a 5kw grid tie inverter to be connected at single phase.
guessing your probably very lucky and none have surged together especially the freezers that model inverter does have 2.2kw peak though. Im more curious now what OP`s inverter is i just re read the original post and he said its 6kw peak is that western standards peak or chineaseium standards?
Only thing I would add is, is it one of those very cheap solar controllers? Did you wire the fan into said solar controller or directly to the batteries? The $2 solar controllers are a toy and when people use.them 90% of the time they have issues from not being able to output rated loads to...
Home assistant with power meters would likely give you a better understanding of your usage and there might also be a way of adding the agile tariffs to show you when to use certain circuits which could be set up automatically to say charge the EV when the tariff is at its lowest.
Few issues...
Don't be foundations on pretty much every building are almost non existent even massive piles sink we ended up building the whole house on a 24"floating slab the locals were very confused as they normally deal in 3inch slabs and pig wire used as rebar.
How's the pwm signal? I gave up using 8266 as it's all software defined but my use case was lights and far more obvious esp32`s are hardware based so I got far better results though it didn't help I already had alot of pcbs that were based on the D1 mini, thankfully I got a hold of a few D1 32's...
yes it maxes out at 500v but i dont really want that many panels as its mainly going to be off-grid and with the heat here id like to stay as close to my average load as possible and just let the grid handle the spikes.
yep silly cheap about $70 a 550w bifacial atm and thats without any...
It's a big part of why customers love them and external manufacturers hate them, their attention to detail is most definitely the highest in the world. Even if a product is produced outside Japan, the factory will have a Japanese QC department which will only allow the highest of tolerances.

We have replaced our ftth cable more times than I can count due to squirrels I feel for you op.
But for future reference even if the cable is direct burial, conduit is always best as you only need to dig once and then if any issues appear you can replace cable as needed without having to dig again.
Yes you will obviously get better conductivity compared to dry earth the resistance on our house will increase a fair bit during the end of summer until the rains come in spring.
That's not a bad idea tbf why did I never think of it
If the input has a load other than the inverter I should have something to measure, the back feed will try to feed those loads and give my CT something to measure
Edit late now my brain is mush
My epever and others on the forum have had it drop into pwm mode when voltage is below 20-21v but I've never attempted the high end of voc nor have I seen any reports of it, not to say it isn't happening. You could try taking one panel out of the series and check if the remaining two are...
Yes kinda esphome is more the information broker and coding companion similar to Arduino ide this allows you to program the plc/sbc which then talks to home assistant and stores the data.
No expert here but personally especially getting started and the fact you will likely want to charge ev,s, pools, ponds and so on at a later date I would look at the 10kw(41amp) range to begin with, the idea you could add more in parallel working as slaves and anything above 10k starts to get...
The barrel type regency stoves were in many of the modern barn conversions I worked at, had really nice aesthetics. Though esse stoves were bulletproof especially the older ones. For the eco type it was burley with their catalytic converters and the mega rich always had AgA
