The rubbery varnish will be conformal coating maybe the BMS has been repaired and wasn't finished properly IE flux not removed and conformal coating wasn't reapplied.

I grew up in the Welsh valleys where many houses were built of Beaufort bricks which were known to be one of the hardest in the world, the US shipped something like 40,000 of them from wales to NYC for the foundations of the Empire State building. Tradesmen hated them as trying to fix anything...

It's there but considering it has the 3rd highest likes(wills other comment is second)it's not in the top comments you have to filter by newest first to find will's essay.

Just ran into this short about insulated cpc's being "great" my thoughts are it's great from an installers perspective but from a safety standpoint surely it defeats the point of a CPC in Twin and earth.

Because I doubt any off shelf shunt I buy can configure to my smart home without alot of messing about. I can buy a pzem module and esp32 for less than $10 put it together in 10mins and program it in 2mins but I'm just unsure if I'm supposed to use voltage as my parameter for soc or there's a...

You won't find these in a telephone interface box there over 1ft long and some have almost a 2inch wide head. For scale that's a piece of 2 inch wide L bracket for holding up an AC unit

The sensor actually tells you how strong the rainfall is, so I'm unsure how that would affect it.

So even with easily accessible graphs and figures it's almost taken me a week to notice but my production has tanked. My vmp is at or below rated vmp nowhere near voc so I'm unsure if it's the panels or the inverter. I have a load greater than production so its not normal clipping I had a quick...

Maybe I'm wrong in thinking it but giving yourself a public DNS entry or a static IP means you have a fixed address for someone to constantly probe? As far as zerotier credentials I see your point it's a bit warden password in my case but I should change it more often. Though if I wanted to make...

@Daddy Tanuki Did you have any luck speaking to riello in the end?

I'd be more inclined to trust a battery manufacturer rather than a company essentially making a large lunchbox. I asked this question to @battery_professional but I did a fair bit of materials science and I'm thinking it has something to do with the way the cells plates are layered but no idea why.

Most definitely

Sorry let me see if I can help, from what I understand you would want a off-grid/hybrid this shouldn't back feed and has a built in ATS so it would only pull from the grid when solar doesn't produce enough to satisfy your demands

Sorry out of the country ATM so haven't been so active . They're pretty monstrous 50% heavier than a typical 400w I'm pretty sure china just use SEAsia as a testing grounds there's very little difference in price to the smaller panels so your obviously just gonna buy big rather than try look...

Have pretty big selection of torque wrenches and screwdrivers Available here Good shout but likely available here Have plenty but I will likely grab some known quality ones when I'm in the UK I'll be making my own busbars so I can select bolt sizes based on lugs Think it's made in china I...

Mineral oil should be fine with an aluminium coil the only thing I would worry about is any plastic or seals they tend to swell when in contact with it.

What's the voltage of the bank? Are you connecting batteries in series to increase the voltage? If so I think it's recommended to add a battery equaliser to dumb Lifepo4 but other smarter minds can comment.

Don't start adding unknown Chinese resistors to an Asian grid supply your likely to get yourself or someone else killed. I've had voltage spikes of 900v plus when something has happened to the grid here, either find a ground on the building or add your own( ask landlord permission to place...

I noticed them both also I thought they saw some other new members asking about big builds and smelt blood in the water. I gave this one the benefit of the doubt and advised him to change his profile photo(advertisement) and to read the forum rules but he never messaged back and went on to play...

This will be news to many many members here

Since this a forum designed to help others, why not share your better way instead of just telling other people their wrong like you've done on multiple other threads.

I'll take a look not 100% on if the pzem DC meter can interpret direction of current flow but you've atleast given me something I can look at tyvm Edit: yes the pzem DC does record current flow direction

I'll do some more checking/praying someone can give an answer. It's becoming harder to find lower Imp panels here without spending alot more per W these at 13.42A are the closest to sweet spot I could find anything lower and I'm paying the same price for a 370W as I would for a 550W. I know...

I honestly don't know where you could buy a single PV cell for as much as he's quoting maybe he mistyped 5,000 PHP as 50,000 a 600w longi is about 5000.

Might be possible to emulate a pi on a x86 machine and try to install SA on that but the chances are pretty slim.

Wera ones are pretty expensive here they don't seem to have a decent trade agreement and they aren't available individually so I would have to buy a full set at twice or more the price. Delivery for most products I buy domestically or from china is either free or $1

I fitted my solar just in time for monsoon season haven't seen a decent day yet and they say it might last till the end of august...

Used M18 for almost 20 years I guess the first combi drill I bought was brushed think I replaced the brushes a good few times and the gearbox eventually packed in about 10 years ago next drill packed in a week out of warranty newer stuff wasn't built like that but it's still not bad. Moved to...

It's really not that bad with a reciprocating saw drill a hole in the wall slide the saw in and have at it probably takes a minute to cut each one. I've made a fair amount of flower pots with them but never built a road.

Yes there's a ton of multiplying filters if I remember correctly just had a quick look at the code for voltage and it's somehow offset by current input but not clever enough to work out how. lambda: |- if (!id(grid_active).state) { return 0.0; } return swapBytes(x)...

So I've solved it but it was weird, somehow the AiO had managed to set itself to utility first no idea why that limits it's solar production. I'll be rewriting my firmware for my monitoring and removing all the modbus writes to be safe. Yep it was certainly worrying me. This unit actually...

So B- to battery negative, P- to charger negative, your individual cell wires can be seen below:

In theory he should be able to move the living room sockets MCB to the protected side but there maybe faults or issues that prevented them doing so in the first place

Btw the maths seems wrong voltage drop on 4awg at 12v and 2ft is 1.33% so 0.1596v at AWG4/0 it's 0.28% or 0.0336 I'm getting closer to 5w lost on the 4/0 no idea how to calculate the twin awg4

TIL Thanks this was where I was confused I was thinking it was for motor switching. That's what I was thinking and by using each side a common dry contact relay used on many esp projects(NC/NO) you have in theory taken care of the safety aspect rather than having individual outputs control each...

Earthworms likely drown here, high water table and high likelihood of flooding that's why I was thinking about the coils in my earlier post. It's mainly tobacco and paddy fields here. If you dig a hole here it will likely be a pond, though ATM with the rainfall you don't even need to dig a hole...

Yep ran this code also and got

If your having trouble with bus bar sizing flexible options are available shown below.

Only now during summer though as we head to winter the sun will drastically drop to the south and in theory we should get better producing days in winter as there's less cloud cover and no rain.

Not sure if this is the correct section but I'm trying to find an alternative to no-ox I could try pick some up next time I go back to old blighty but finding something here in Thailand would be preferable. I've seen some carbon conductive greases available from specialists here but anything...

Nakita,JA,Trina,Sunpow,Longi,Jinko,Eve there all around the same price here.

No doubt I'll sleuth the Youtuber tomorrow see what shade I can find on him😉

Would explain alot if the connector wasn't fully seated and makes sense looking at the way the connector is in the first photo posted by op there's a distinct ring of carbon rather than just melting, suggesting there was an air gap inside.

I'm pretty sure it's actually the release of pressure and a massive steam buildup that causes them to go pop but as you said as long as the fitter has his certs and does his due diligence then there shouldn't be any issues.

Here we have both on-grid/hybrid and off-grid hybrid on grid being grid tied but has a battery, off-grid/hybrid being one that's off-grid but can import grid power not export it. From my pov and the terminology used in Thailand/China and off-grid hybrid perfectly suits his needs I use one as a...

Doesn't seem to be any gas accounted for on this graph are they hiding it or have they shut down all the lng facilities also?

Think I'd prefer to store it for a week live normally and review the data when I have time rather than spend every waking hour watching a screen like a modern day teen.

Likely anywhere from 100-300ft I'm still undecided on where I'm building the room one position has good shading and lays directly beneath our incoming grid power the other spot is closer to the fields but requires a fair bit of alterations to the farms main lines.

Arc extinguishing maybe different when comparing AC to DC I'm not sure As far as old block items I bought a large consignment of west German drill bits some time in the 90s probably have a few kicking around now damn they were good.

Just to put an end to this thread and quell any disinformation, the numbers were all booked by my poor understanding. The AIO efficiency is 100% minus 20w for actually running the inverter (not solar efficiency), within the code I'd written for efficiency I'd forgotten to take into account AC...
