Yet another inverter thread.

[Rickster]

Currently want to get an inverter for stage 4/5.

IVR-1200LBKS MECER 1200VA 720W with 2x 100AH 12V Deep Cycle AGM Batteries.

Just to power a TV, router, LED lamp, charge phones, DSTV decoder and an android box.

Would like to get 1 Hubble S-120 but stock is an issue.

Also how much electricity would it take to charge these batteries from 50% to 100 in kilowatt hours.

Cheers

At 50% DoD the battery is 60Ah, if your charger is 10A then it would take 6hrs to charge the battery back to 100%. 10A at 12V is 120W, 120W for 6hrs is 720Wh, that is 0.72kWh.

The 720W is 12V so you don't need 2 batteries, unless it's just for extra capacity. I would advice you against lead acid batteries but if you don't have options on a lithium battery then a solar panel works very well to keep the batteries charged, I have a 200Ah 12V setup with 200W solar, I can survive any loadshedding period with it as long as there sun is out.

Read through the first couple of posts:

Mecer 2400VA Inverter (Community Support)

This Thread is for the Mecer Inverter only. My personal opinion on the unit: Seeing that there are lots of question and in lots if threads, here is my review/input on the Mecer Inverter. Instead of reposting I'll just reference here. I'll add more info soon. This should give you an idea what...

Any other questions related to the inverter ask there.

Stock is a major issue for batteries.

lead acids won't survive stage4+ blackouts. Wait for lithium or if you can't wait then get LA and be prepared to replace them in 6 months.

LFP's are about 95% efficient in charging where LA are about 75%.

I agree.

But if you need something now now, lead acids are your best bet.

If you know that you will be keeping your lead acids at 70%ish after every cycle of loadshedding then its viable for long term

If they never get to 100% then it's a problem. Having 2 in parallel will help with DOD so will have better chance recharging at 20A between blackout slots.

but like @TheChamp suggested, adding solar will help keep DOD low helping improve life of the LA batteries.

Yes, I was wondering if i can put 2 in parallel and charge at 20A, that's fine right?

Yes, and having 2 in parallel will halve the load on each (less amps on each), extending their capacity also, as you can see the capacity reduces according to load.
