Sorry offtopic rambling after pointing out our 8 year old AC units can select a percentage of power draw. Just looked now at lowest speed I get a pf of 0.97 at highest it's 1

Most minor offences are about $12 in my area

Good trick but the reason it turned into puddles is I didn't clean off the oxide first this was a long time ago and when I was far more arrogant than I am today. I always thought Its better to learn doing something which I I know now is only partially true, you need to understand the underlying...

I'm thinking they just changed the branding as it was synonyms with cheap one use tools

I'm a glutton for punishment I used to buy electronics from BANGgood

Wonder why that is? I've never had any issues using UART devices though all my ssc's and aio's use recommended standard either 232 or 485 I use alot of pzem voltage meters with CT clamps all work fairly well but the more you add to the UART bus the slower the polling rate has to be set. I went...

I'm guessing it's srne as they produce them for alot of the other Chinese brands but when I purchased my cheap Powmr HF AiO I noticed a few LF AiO for sale also, I'm a idiot and have no idea of the difference but thought considering the content of this thread it might be relevant.

I started with pfsense then moved to opnsense you would think that two systems built on freebsd by exactly the same initial developers would be practically the same but opnsense had a different way of building firewall rules, took me ages to get used to it. Now days I only log into it for...

Esphome has a provision for ble proxies lots of videos on YouTube but as a standalone system maybe something like this could work. https://docs.espressif.com/projects/esp-idf/en/stable/esp32/api-guides/esp-ble-mesh/ble-mesh-index.html

I do enjoy watching contractors trying to fix fibre optic lines with hopes, dreams and tape

Features and real life numbers can be very different I'll take a look on my ac units tonight and see how much the supposed percentage actually affects power draw.

yes electricity does take the shortest route but in resistive terms. Its not going to go directly down, through concrete when theres a grounded steel frame above you. I am indeed suggesting that that hollow steel beam is welded to the rebar in the concrete pillars that supports the whole house...

unsure of what solar charge controller you have or what your panel specs are but if you connect panels in series you need to stay below the controllers maximum voltage/power(watts), if they are in parallel like your are then you need to stay below maximum current(amps)/power(watts) of the solar...

$110 per cell? How do I say this without you feeling sick? Give a bigger number? ¢3000 per cell including delivery. I looked at the 280ah cells ¢5000 per cell but those are in aluminium housing and your earlier post suggested against this. I've also looked at the sinopoly cells they are...

I'm pretty sure this is the rare case, there is no settings , Maybe a default cutout for low battery voltage but the fact as I stated earlier there is certainly no charging cutoff for over voltage by default

The pi would need some form of powered external drive, SD cards tend to die doing any form of data logging and usb powered drives tend to corrupt after a few months because the pi can't produce stable power. Some form of drive dock with its own dedicated wall warts works best.

So something has caught my eye I know they're 15s and from my initial research seem like I could have issues with BMS communication but at the same time they're pretty much the same price as 15 DIY cells plus I would have a nice case. If the BMS issue is really an issue I'll just rip out the...

Hopefully not breaking any rules here but the video below has an interesting concept using home assistant. skip to 21:30 to hear him explain the software side of things if your not interested in the Tesla installation. He's buying electricity at £0.15 a kWh and selling it back for £4

Taken directly from their Facebook page Note the flashlight branding

As mike posted above the wiring of the batteries in parallel is one important thing. Personally when wiring any batteries in parallel i first put each individual battery on a smart charger and set that to storage mode, this on lithium batteries brings it down to around 50% charge and gives you...

Sorry you are indeed correct I hadn't accounted for grid charging in my efficiency entity.

Sorry no idea how to explain it mathematically I'm more hands on I'd likely just take my measurements cut a stick to length at what the gas strut should be compressed and treat it like a puzzle physically moving it till I got the right angles and mount points.

Tbf I do use chat gpt alot of Thai law and it was instrumental when I decided to tell the British tax man to F off, but stuff I actually want to learn and am interested in I tend to do the research myself I'm less likely to forget it then.

https://www.san-eee.com/en/ seem to be a riello stockist I can't see the heavy oil burners in their stock but from what I've made out they claim to have them. Riello was Italian brand, but are now made in Ireland I think, but some parts are imported from Japan (maybe control module)

Blue cable on the shunt goes to battery side, yellow cable goes to load side.

This just popped up on my news feed. https://www.reuters.com/business/energy/us-lawmakers-seek-block-chinese-firms-solar-manufacturing-subsidy-2024-07-31/

Just noticed this thred and thought I would chime in some, OP is working on their own install thats totally fine in the Uk and doesn't go against any regs or part-p as far as I'm aware but for insurance purposes you need a qualified electrician with inspection and testing licence(not sure if...

They may do in the future but Thailand is the wild west and we still use dial meters here, everyone has awful power factors because of the massive amount of poor quality motors being used to power everything from pumps to processing equipment the backfeed is likely low on their priorities.

If there that concerned about not paying a living wage why not move to the other country, that's what I did. Typically I pay a guy to cut our hay fields 10% of my hourly rate for a whole days work and that's still double minimum wage.

Sadly they don't work here, the humidity is that great they just can't keep up even our oversized mini-split's will struggle to keep up in the next few months as the rains continue but the heat rises.

Stakeless testing. https://www.coleparmer.com/tech-article/ground-testing

I'm using dielectric on all my current connections(humidity here is insane this time of year) but I don't have any busbars or complicated wiring on my current system. It's more for the next project which is still a good few months away but I've learnt to look out for these seemingly...

Yes sadly this is the issue with recording soc via voltage and is normal for these epever ssc's, the battery does actually absorb the voltage quickly which as v_green explained normal behaviour for this SSC. But at least we know the panel is in fact working correctly. You might be able to alter...

Just looked them up, surprisingly the full kraftform set doesn't look that expensive there it's comparable to the wiha if your ok with the interchangeable blades. https://www.amazon.com/KRAFTFORM-KOMPAKT-VDE-PACK-26PCS/dp/B0CX1V1NLV

That's the thing ATM they are all pretty much the same price $68 be it 375w mono or 550w bifacial or 600w mono that's why I don't know what to get. Yep I lugged two 45lbs panels up a ladder onto my roof on my own but the larger panels I'm looking at now are closer to 60lbs each and I'm most...

I would think you can walk in any panel if the back is suitably reinforced, it's obviously going to put tread wear in the surface but I'd think that using something like spray pu foam on the back of a panel to fill the void and placing it in a flat surface would be fine. if you can source cheap...

I'm just using single CPU 4 core 1u poweredges (cheapo) either ha plays better with them or my ha is sluggish and I don't know the difference but I've never noticed any slowness.

There's alot of shine in that box first think I would do is tidy that up cut down any excess conductor or double it over, the main neutral would be better fitted into the other side of the connector allowing better access to the low voltage fuses. Skipping at AC unit entirely I'd recommend a...

Or if you fancy a trip in the camper to Tipperary (it's a long way) there's Li-Gen batteries there no idea how good they are or if their pricing is competitive but it's an option.

The max will require a gnd from the BMS you can't connect to the esp gnd (I've learnt the hard way and cooked a few max chips in the past) also make sure the Rx from the Max goes to tx on the esp and vise versa for the other wire. Set up UART debug in your code verbose logging and check what...

So would this trip if a live/earth bond happened? Edit: thinking about it even if it did trip the live would still be bonded to earth

Lol after seeing another post on the forum of someone buying from Jenny wu I had to take a look, so the wording is funny on the listing. There's nothing about the batteries being new which they obviously can't be but it does state the qr codes are new even though technically they aren't qr...

All around $70

Bit it's spherical unless they didn't have a bolt and used some form of threaded ball joint.

From looking at the documentation it seems connecting the grid tie to the gen port only really applies if you wish it to also charge batteries but then the gen input will open if your batteries are full otherwise on the AC input side it will stay on constantly. I know you have a fair bit of...

so galvanic, i wonder what reacted, I'm guessing the mc4 conductors are tinned what about the cable? was that tinned? in theory tinned copper shouldn't corrode but just the act of crimping will break the conductors coating and make it more porous (susceptible to corrosion). good info though...

Should have sold the grid tie and bought another Deye yesterday in the sales when they were under $1000.

its a real gray area with UK regs anything existing can be out of regs anything newly fitted must be within regs I'm unsure how this applys to home owners but wood is a fire risk and as a home owner you should treat regs as the bare minimum(crap job) and aim to do better.

That's what I would think.

Id say @wattmatters is spot on with discharge current/power otherwise you would need some form of template/helper with soc used over time to use as a trigger.
