Post 02 2021 (Why solar will never work in South Africa)

[tec0]

Hi again, for me it is about functioning. Supper capacitors isn't new, Fact is since the the second world war but was officially re-purposed in 1982 round about. But it has been around since the idea of high energy weapons. More to the point China and Germany did a lot to push this tech forward but sadly a lot got lots.

Case and point.

Will it work? Yes.
Is it expensive "for now yes"
Is it better then batteries "No discharge is still a problem however it is getting really good"

My source: BU-209: How does a Supercapacitor Work?

That said i am sure this tech will revolutionize power storage.

But right now for me this does not mean a whole lot.

Currently i have access to:
Generators
Solar inverter and batteries.
Gas.

So this is what i have to work with.

Why i go with gel batteries? no maintenance cost 200amps per battery is good. Are they expensive? YES are they long lasting? YES. Can they get damaged? YES

But the same is true for a Lithium battery. Yes at round about R7k to R14k they are cost effective. Are they long lasting? YES. Can they get damaged? YES. So why don't i go for it?

As i understand it, they need "special chargers" and my current system is simply not configured to handle them. That means on top of the cost of the battery i need to upgrade my system.

However when my business goes in gear again later this year. I am planning on a massive solar upgrade. Along side it i want to install a 25KVA Diesel generator. Along side that I want to upgrade my home's security.

We will see what 2021 holds. Best of luck for all of us this year.

I think R&D made promises its behind can't cash at the moment. It works I saw the introduction a while back BUT the manufacturing process isn't easy. So i will give it another year maybe two before we will walk into our local solar store and they will try to sell us these batteries at a mark-up at first until circulation is stable then prices will drop a tiny bit. But for now i am sticking with gel batteries. I got to trust them and like how they work. It is not a good tech but it is a functional solution for my use case and that to me is the important bit.

Whatever happened to the super battery Eon Musk developed and was going to sell to every household?

Hi Teco,

Have a look at this new LEAD CARBON Battery
I believe they do charge faster, and have more discharge cycles.

Teco - with a very limited knowledge of lithium batteires and charging ... it seems that most inverters have the abiltiy to adjust the charge profile to suit the type of battery.

Honestly both the Lithium and the lead carbon battery looks like good options at the moment. My one family member has a massive system and it might be time for me to go have a look at what he is been doing as well.

Old model inverters do not have this option.
In fact when purchasing an inverter, the question should be asked whether the inverter can accommodate Lithium batteries or not.

100% agree, older models like mine do not support the charging and i was advised against using my system and my stand alone charger for these batteries. However the new charges isn't that expensive.
