Need Advice for either inverter or power station

[Hero Steel]

Hi fellow Carb users, I need some advice.


With all the load shedding these days and my town having two stages after I come home, I want to get myself a power station or inverter just so can do something else than sleep or sit in the dark.


I am getting a GizzuS UPS for my fibre and router.

So my power consumption will be as follow.

My desktop pc has a 450W power supply, a 144hz monitor and a speaker which I have no idea how much power it uses.
It would be less than 600W if it's running at max which shouldn't happen realistically right?

I saw the following on TAKELOT and I want to know if it would be a good buy or if is there something better I can get at a reasonable price.

Ideally, I want to spend less than R12500 to survive 2 stages of load shedding while also having a decent usage lifetime without issues coming up. I heard that getting lead acid and gel batteries is just asking for kak in that regard.

I also want to know if someone that is knowledgeable about inverters can tell me for how long the above-mentioned inverter will last me in terms of hours depending on if I am gaming or just watching youtube.

We ended up getting one of these batteries, which looked like a good middle ground, for cost / life.

The problem with these type of units is that when they go pop, you can’t really do much with it.

they are convenient but no point having something conveniently dead.

I rather get a separate battery and an inverter. Then if the inverter dies, you still have the battery that can be used with another inverter.

First 5 clients to order off Takealot and leaves a review on the purchase, will get R1000 cash back from me. Please send me your Takealot order number from Takealot to verify and I'll pay you. Nice and simple

Here’s a battery for R7500 if you leave the feedback. Maybe @Tsakie can help with a small 1kw inverter too on a trolley.

Also depends where in the country you are.

Regarding the time, if you pull 500w from a 1000wh system, it will last 2 hours but in reality it will be a bit less than that as there probably only allow 80% discharge.

Thanks,
Did you build the system or did you get it preassembled?
What kind of battery is that? Why does it say it needs to be topped of with distilled water?

From the spec sheet
Tubular Plate Design And Lead Acid Storage

Some maths.
80% of 180ah ~ 144ah x 12v ~ 1728wh.
1250 cycles means 2.1 MWh from the battery.
@R5749 means R2737 per MWh

The lithium battery I linked can do
100ah x 12v x 80% assumed 960wh
5000 cycles means 4.8MWh from the battery.
@6500 with the cash back means R1354 per MWh

When lead acids reach the end of their life, they are useless.

When lithiums tech end of life, they still have capacity left, normally 50-60%.

There’s a lot more to it than this like peak power draw where the lead acid would be better but if designed properly, lithium works out much cheaper in the long run.

You decide which is better based on you current affordability.

Thanks, I'll take into account what you have said and decided what to do forward.
