Taking lights and internet off the Grid (mostly)

Interesting side note for those interested in the Tesla batteries. Was speaking to my brother in law who is an engineer in this field, and the price of the 3kva 1hr batteries have dropped to around 16k (were over 35k).

You are right , for those who do not know the basics of electricity , batteries can explode and injure people if over charged or shorted ,there are many hazards .
Do not play with high amperage electricity if you do not know what you are doing .

Jaws677, or is it greg-SA?, should wait until s/he's done Grade 9 Science. Basic electricity knowledge seems to be absent.

didn't they run out of stock or something ... so unlikely they would drop prices with such high demand.
any link you can refer to for those interested?

I will try get that out of him. Will reply here when I get a response.
 
Isn't the real question is how do I make my spinning disk elec meter turn backwards after my batteries are charged?

Old Post, but rather read properly before you dis someone...

So the two 12 V batteries in parallel will give me 24 V ?

Thanks for the sound advice.

Dude, you obviously didn't follow the posts properly... I said that my Axpert 1kVA inverter is a 12V system, and I use 2 12V batteries in parallel.
 
I'm running lounge at around 300 watts average on my 2x105aH batteries for 3 hours. Longest i had loadshedding last year and batteries hardly battered an eyelid.
If you find your batteries are not coping either cut down on usage or buy another 4 and rewire everything in parallel series to achieve your 48 volts @ 360Ah

So what I’m getting from this is that the kit should be fine for my use case....

Wanna get lights on Solar soon after as well

Lights and lounge possibly. Maths for lights came to 0.7ish kWh for 5 hours.
Lounge plug around 1.5 kWh for the whole day as an average.

Do you leave all your light on, always? Or only a few, for the time that you're awake, if at night :)

Geez, that sounds is pretty heavy!
I have a 800W inverter, for my lights (all LED) and lounge (TV, media player, Wifi, Fibre, network, alarm, etc). Typically I draw way less than 400W. Last time during load shedding, while streaming to a TV and with kitchen liunge lights on, I was at 200W.
