Not if it's a Ferrari

Does that Seplos BMS get hot? If so, when will you be fitting the fan?

Sounds like a good idea. How do I locate one of those? I'm in Buriram and will be needing a new passport by the end of this year.

10 Minutes if you're lucky

No problem with the battery in mine. The sucksion pud drops off when it gets too hot and the camera drops into the shade by the gear shift.

Is that a pun?

???? My "system" is an antique with Gel batteries and is completely and totally dumb. Maybe each unit sits there talking to itself but whatever, there's less things to go wrong and no bytes to worry about and believe me, at my time of life that's a plus.

If I remember rightly, you got a good deal with Sofar so you are probably still ahead. Will the flying cap balancer work with the Seplos connected (just coms) or does the coms need a fully functioning Seplos balancer to be able to communicate. I am thinking that unless there is separate monitor wiring that may be an issue.

I had a look at your Seplos balancer and this is what I found https://www.seplos.com/sale-13671689-24-48v-8-16s-50a-smart-solar-lifepo4-bms-monitoring-system-lithium-ion-battery-management-system.html Current Balance Passive balance 150mA(Max) Am I looking at the right thing? If I am then it is small wonder the charge controller needs to be attenuated for the balance to do its job. 150mA is really not enough and passive? Ouch!

Agreed but all these snippets of information are dealt with locally and alarms sounded. There is no reason to share any of this between other units. For example. If the inverter starts to overheat it will control it's own problems and could shut itself down. The charge controller doesn't care about that and neither does the BMS. Likewise any problem with over current from/to, state of charge of individual cells and over/under voltage of the batteries is controlled by the BMS. The inverter and the charge controller don't need to know. The inverter is only interested in whether there is enough voltage to run it's output. Similarly the charge controller is only interested in filling the batteries. It doesn't need to know if one cell, for example, is not performing so well. That is the job of the BMS. Communication between all functions might be a nice to have but it is really unnecessary.

Yes this seems to be a possibility. Squatting in Thailand was traditionally permissible under customary law and adverse possession can occur after ten years of continuous occupation From Wikipedia look up Adverse possession. The question of direct family might become a bit tricky. Why are the two women not talking?

Personally I see three separate, independent units which have no need to complicate things by communicating with each other. The charge controller who's sole purpose is to try to put power into the batteries at a rate determined by the battery type. The inverter which simply converts incoming dc to the required ac voltage. The BMS which is there to give electronic protection to the batteries, balance them and report on individual cell state. Each of these units can have the capability of letting you know if there is a failure. They don't need to control each other.

Scary

What information about your battery pack are you getting now?

I had a problem with rats nibbling through some temperature sensor wiring on the roof of my well shed. After the repair I ran the wire through a flexible plastic conduit. End of problem. It seems the rats have no liking for this type of pvc.

Might have difficulty getting them back in his mouth after.

That'l be fixed come the revolution.........????

"Among such products are corrugated, craft and printing paper, bicycle and car tires, motorcycles and trucks, water pumps, fertiliser, chicken, chicken eggs durian, powdered milk and milk products, wheat flour, pork, canned food, student uniforms, vegetable oil, medicines, cement, steel rods, iron sheets and structural steel, shampoo, sanitary paper, sanitary napkins, detergent, dish washing products, diapers, soap, farm trucks, pesticides, harvest machinery, animal feeds and more." If these prices are to be frozen for another year, the implication is they are already frozen. That being the case, how come fertiliser prices, for example, have more than doubled?

Try not to worry too much. It'll all change again soon

Looking around CANbus things I notice Arduino have some suitable modules. Maybe there is a way to translate from CANbus to 485. Not much good though unless the origin source code is known.

I thought CANbus was for mobile applications like automobiles and aircraft

Curiosity, being what it is, has me wondering why you want to change your BMS. Was the other one not working correctly?

My wife and I have looked at the picture you posted but unfortunately there is not enough information to see what type of land document it is. If you could post a bigger view showing more writing below that would confirm the type of land being offered. Also knowing the colour of the bird picture at the top of the document would help. It will be red, blue or white.

I also have notice that the Aliexpress prices are more in line with retail prices for goods in Thailand which seems to be double what they are on Alibaba and Made-in-China. Buying direct from the manufacturer is generally possible but the "sample" price is somewhat higher than the 100 off price.

I agree with that entirely. When you are making your own power you are always far more conscious of the supply limitations and therefore inclined to think on the frugal side. Mind you, that's not a bad thing anyway if you are at all sympathetic towards climate change.
