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 rite , 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?

Hehe. Only if you got it at the Checkers check-out. Must've been greg_SA then. I missed your wink. Mybad.
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
