Bros wood will burn without oxygen.
I dont know him but i will make research if someone told me that 2+1 is 4.

Thanks for the input. Not to appear gropping at semantics, the keyword there is "burn" which is quite different from boil or "heat" which was used in the snapshot, the latter two being able to take place as incomplete process in the absence of oxygen. Pressure cookers expel most of the air yet the substance still cooks, but not aflame. Only a few substances are effectively incendiary enough in the absence of oxygen and I don't think wood is one of them. That is why wood fire as a class two cat can be extinguished by a fire extinguisher because it suffocates the wood of air whereas a Lithium ion (LiNiCd) fire ńa werey fire classified as class four, not easily countered by your common extinguisher.

Heating in the absence of air I believe deprives the end product of Oxygen species as part of the compound which in turn makes it highly reactive (i.e hungry for an element to combine with to stabilise itself). This of course stands to reason because the "activated charcoal" end product is used in various applications the one I'm well used to, as a medical personell, being to detoxify the stomach contents when poisoning is suspected. The charcoal hungrily binds to any elements or chemicals it meets in the stomach in such instance. On the other hand, if ithe wood were aflame - a process clearly requiring air - then the end product will be quite different from that of heating it in a vaccum.

Again this is me just pulling it out of my basic knowledge residue (yet to sit down and research it), therefore I may still be incorrect, but I think my basic knowledge says otherwise.

Thank so much

Some Chinese sellers already trying to cash in on the great reputation of BYD blade battery .

For all you care, it may just be one yèyẹ́ factory that made it into the form factor BYD's battery are noted for.

Or it could be "grade F" BYD blade batteries.

Excellent. There is no "burning" without oxygen. The technical term for burning is "Combustion", while what the gentleman was talking about is called "Pyrolysis". However, your explanation about production and mechanism of action of activated charcoal is not correct. Please check it up. Activated charcoal acts by trapping poison, not by reacting with it. It is a physical process, not chemical.

He is saying things in a lay man terms.
If u were asked to touch ur throat u will touch ur neck and ur neck, neck.

Definitely, not actual burning ( with an obvious flame) without oxygen but u which term will u use when u see smoke out of a "body"?

Those who are into charcoal production will not burn wood to see actual flame. Na ash be dat na.

For water to boil out of wood shows a temperature close to 100 degrees.

*****There is no smoke without fire****

You get my point?

Probably I was supposed to quote the burn.
Correction accepted.

Yeah that's true, adsorption I think is the right word. Thanks.

Overall I think the OP should try to be very clear, simple and explanatory with his depositions rather than the confusions he fills his arguments with, saying it authoritatively as if his is the holy grail and all other things in the past 1170 pages have been false junks. He stops by occasionally and drops one or two grenades , newbies dey here ó, make una no confuse us.

Shey because someone mentioned resonant inverters now, as newbie, I will start looking around for "resonant" inverters, I'll be like kiekie, adrusa ó, justcallmenuel ó, abeg I need "pure Sine Wave resonant inverter", do you have?

And if as a newbie I now see good supplies of 18650s over FLA, I will turn it down because someone says Li-ion is not good, Haba!

Yea bro

hello everyone,

I am stil trying to get my feet on this solar thing.. today i used a pv meter to check on a panel (africell rated as 300w) . I got a shocking 110w 22v, 4.89 amps.. I have four panel that was first connected by a friend and according to him it was done in parallel. I am using an epever mppt controller 100v 30a.. before now i couldnt generate more dan 280w from this four set of panels my setup is a 4.8kwh litium battery with a 24v 1.5kva scheinder (homaya) hybrid inverter.

Today i decided to connect 2 panel in series and parallel both strings together...

I was able to get 44 to 50v of peak hours with current raning from 5 to 9amps today...

My question is why the low output from this panels....

That's how some people claim ITK everywhere. I saw an approximately 4m setup someone with conscience installed for my boss and I weep.
The offs in the setup:
1) west and east facing panels (16 in all) combined into one CC. The CC is a mediocre type.
2) tiny wires from CC to battery
3) no breaker or protective device between solar and CC
4) no breaker or protective device between CC and battery
5) no SPD
6) wire from battery to a 5KVA inverter 6mm2 wire
7) no breaker or disconnect between inverter and battery
the inverter is the type with huge self consumption.

If someone mistakenly, plug a high power device, the cable from inverter to battery will just melt.

What I don't know is if it's a case of lack of knowledge or greed on the part of the installer. If it's the later, then we have a long way to go in our society. If it's the former, why would someone take up a job he's not qualified to do?

You spend so much money and what you get is a time bomb.

there are very few installers that actually know their onions. if u go to Facebook solar groups, u will weep for their customers and the potential ones. over 90% quack installers!

Test these panels on the ground. Adjust accordingly with a wedge or call som1 to assist u in adjusting to different angles. The result will be different.

Mine is on the ground resting on a 6 inch type building brick. One pv rated 190w used producing 130w. The highest amp I v seen was 10.9A. Cc Powmr. But usually 8a or 9a.

Probably my pv was just a "luck". Bc me sef no understand.

I dey find panels to buy oo even if na cracked.

if ur pv rated @ 190w de produce 130w .. its fair to me.. not my own rate 300w de produce 110... like u said na to bring am come down... but my guy u know how all this 300w panel de heavy to carry....

If it wasnt like this when it was new, its possible a diode in the junction box is open.

Ps I have a DIY installation & would like to add fuses and circuit breakers to it

I'm confused at the sizing

- 2 350W ground mounted solar panels connected in series with 9 meters of 10mm DC wire from panels to inverter

- 3kv 24V axpert inverter with 100VoC, 1000W rated power and 30 - 80vdc operating voltage

- 24v 100AH LiFePo4 battery pack (also conected with 10mm wire to the inverter)


I haven't connected AC charging yet as I don't want nepa to damage my property with their random voltage.


Please what do I need to buy to protect my setup? Been browsing and very confused.

so i nor go fit see panel wen dem rate @300w still output at least 220w. somebody de say make i buy Canadian solaror victron solar panel.

i just need rest of mind. Person go calculate add losses still add jara for the losses . panel go com de Bleep up

Thank you!'
Experience always helps

1. I'd change the wire from the batteries to 16mm ASAP
2. I'd get a 10A 230Vac breaker and put that before connecting the AC supply to the inverter
3. I believe the 16A DC breaker is between the panels and the inverter while the 63A is between the batteries and the inverter?
