4 Ever on, What do you guys make of this?

[Dan C]

R8k is expensive. I have the same spec'ed one and it set me back R4700.

That's why I opted for a 12V system, so rather have my 2 batteries in parallel giving me a comfortable run-time of 4 hours without even getting close to 50% DOD. The batteries life-span will be 2-3 times longer than the way this system is connected.

Please explain logic.

The diagram is hysterical...Im really glad someone drew me a picture of
what happens with loadshedding, I never really understood that my lights go off, with pictures now I do!

It's quite simple really.
Load shedding + no Power-in-a-Box = Everything in greyscale

Almost all Intelligent chargers are in that region.
Only an Intelligent charger can charge a Silver Calcium battery correctly as it requires a 14.8 volt charge as against a Lead Acid battery which requires a 14.4 volt charge.
It also offers a Maintenance charge of 16 volts to recycle the battery once a year or so.
Lead acid batteries only last about 3 years, where if properly charged as Silver Calcium can last up to 10 to 15 years.
I have a 65 ah Silver Calcium here which I use to start my Generator and its in it's 13th year now
You use an elcheapo lead acid charger on one of these batteries and it will die within 3 years, been there

My 2000W PSW Inverter has a built-in charger that chargers my 24v system batteries to 27.5v and then floats. It also depends on the type of batteries you have which make a big difference.

Thanks for some clarity.

The frikkin government should be backing some BEE company, and subsidizing 'sabs' approved units for the consumer, considering they created this monumental mess in the first place, rather than spending billions on diesel.

Last thing I want is to burn my house down.

When stage 3 comes into effect more regularly most of these inverter setups are going to end up being a waste of time. (first shedding, no problem, 2n'd shedding, batteries not fully charged, 3'rd shedding, batteries run flat).

 

[MrGray]

What do I make of this? I make of it that it is an inverter with a battery. One of many solutions. Do some homework to work out if it is a reasonable offer - there is a lot of marketing BS.

Then you can just add a solar charger and panels or more batteries or both.

Been saying the exact same thing for a very, very long time already...

So now you're going to be mixing old and new batteries together as well?

Ok...

Yip can you explain why thats a bad idea if you use low voltage disconnects?

Or just start my generator 3 times a day

What does a "low voltage disconnect" have to do with anything?

It's batteries 101... Without getting too technical, the batteries won't drain & charge at the same rate. If you look at TV Remotes, Flash Lights, even your good old alarm clock - they all (should) state not to mix old and new batteries together.

It's a VERY bad idea and it will reduce your batteries' life span dramatically due to incorrect charging / discharging. But... if you want to destroy and not look after a R2500 (odd) battery to get the maximum possible lifespan out of it, that's your prerogative I guess...

The point is there are ways to protect the batteries from over charging / over discharging not everyone just replaces all the batteries every time. Yes its a good rule of thumb but like almost everything in life there are ways to make exceptions to the rule.

Ok... The entire world is wrong / doing it incorrectly, you're correct

/moves on...

Where did you have this made Dan?

MEH I couldn't be bothered but if you think the large battery banks around the world only buy the same batteries at the same time and never replace\increase them then I dont know.

 

[Dan C]

The inverter/charger (MECER 2400 VA, 1440w) was R1700. Batteries were R1500 each. I put them into an old cabinet I had already. Only other thing I added recently was a battery monitor : http://www.outdoorwarehouse.co.za/national-luna-battery-monitor-double.html

The inverter does not really give you a good indication of the state of the batteries. But now I think I'm sorted

Large battery banks around the world most likely use 2v/3.2v cells
