Inverter and batteries

[dunkyd]

just a quick question, if i had to get a pure sine wave inverter and a 100ah AGM battery, does the inverter charge the battery aswell or do i need some sort of charger, im a little confused in regards to how it works

for example something like this, maybe not this extreme, but https://www.takealot.com/inverter-pure-sine-sine-wave-2000w-12v/PLID68909188

any input will be appreciated.

No. Rather buy Mecer from Geewiz with a built in charger.

that one doesnt look like it has a built-in charger, so you will need a charger.

okay, do you know where i can find one or perhaps have an example or link to show me

I have the 600w 12v version, which is pure sine inverter + charger + automatic switchover and I am running it on a 100w battery.
The 2000w 12v version should be what you want, except they are sold out.

The wording I see, is UPS type inverter.

GeeWiz.
Most good pure sine wave inverters are 24v or 48v, so you'll need 2 or 4 batteries minimum.
The lower end Mecer units are not pure sine wave.

What are you wanting to run, for how long, and what's your budget?

just basic stuff like alarm, fibre router and ONT, TV - but ive heard some bad reviews when it comes to modified sine wave and modern tvs etc hence why im looking for pure sine wave + a family member wants to use ebucks that they have saved up which can only be used at places like takealot and makro

Still does not look like it has a charger, can't see that anywhere in the specs.

Perhaps look at this, it should state explicitly that it has a built in charger. https://www.communica.co.za/products/synapse-3-0v

Why are inverter prices not going down. I remember mercer inverter 720w was selling for 1300 before the whole loadshedding drama started then it jumped to 2300.
I was hoping that the prices would be back to normal but it hasn't.

They arent going down because of the warnings that loadshedding will be back soon. I expect them to go up when it starts again.
It basically becomes an exponential increase because its increases on increases.

Far to expensive for just 500W.

You need to clean your terminals and smear them with Vaseline. A nice thick layer.
