Battery solution - Nian Electronics - 4x102AH - 6000W Power - anyone use it?

[MagicDude4Eva]

Stumbled across this the other day. Have sent them an email to request more info (their website does not work). TBH, I have not spend much time on alternative power solutions but judging from how much money some people have spent on generators, their solutions sound to overpromise - or? I mean a geyser is and refrigerator chow throw power like crazy (and if you double up, you can literally support stove/oven/waterpump) - any feedback:

Update: Got some more info, just had no time to post it yet - here we go:

Wow that is massively overpriced, and won't deliver anything near to what is promised.

+1, can build a similar system and have it installed for far cheaper than that.

They claim 5-7 hours running tv, fridge,geyser,10 lights etc. on only 2x 102 ah batteries .. :wtf:

indeed..
Some pricing from SAEG http://www.saeg.co.za/

I am not even mad, that's amazing.

Errr... forget the backup claims , but how is it massively overpriced and how can you build a similar system cheaper ? please enlighten me ...

Well it's all speculation of course without knowing the exact inverter and batteries, but a few assumptions can be made given the other ridiculous claims, encouraging people to run an oven and geyser off it etc. etc. and the fact that their web page doesn't even work and so on, and just from looking at the picture (of an inverter that looks like its probably meant for a car)

Assumption 1) The batteries are going to be badly selected cheap ones.
Assumption 2) So is the inverter.

Cheap '3000W' PSW inverters can be had for ~R7000 - less if they are actually using a R1500W inverter with R3000 peak or a MSW... Which giving the other ridiculous claims both wouldn't suprise me.
105AH Deep cycle energizers can be had for R1400, and that is not even the cheapest nastiest ones, who says they are even using deep cycle.
Another R1500 or so for a small charge controller - again they could go even cheaper here.

So even if we are generous on the costs of wiring, switches and labour you are looking at about R12000 for an equivalent system, so that is a R10k markup, possibly far more.
Which isn't to say you should go ahead and do that either



Now of course I could be wrong and they could be using high quality parts for everything, however unless someone can give me a reason to think that I'm going with 'massive ripoff that will probably burn your house down if you try use it how described.

Thanks for the detailed explanations. I spoke to the sales guys and they have said that they will email me more specifics (including specs of parts used). I will post once I have the details. BTW - the guy apologised about the website not functioning - some IT issue.

Yes overpriced, I have 4 x 100Ah batteries with a 1500va PSS inverter with build-in charger. Paid about R12000 for everything.

I can run 2 lights, 1 LED tv, PC and HP microserver for about 4-5 hours.

Edit: No way you can run a geyser as well.

 

[savage]

The run time quoted leaves much to be desired :wtf: but 3kW/205Ah at R22K and 6kW/408Ah at R35K sounds reasonable for a PSW.

I'd guess on both models, you will be looking at +- 70% (max) load in order to get through a 2 / 2.5 hour period of load shedding.

Baring the obvious lies about the run time offered, it's pretty much similar to what I charge to supply & install Axpert (PWS) units.

Well, 1500VA is FAR off from 3kW, nevermind 6kW... So you're not exactly comparing apples with apples now, are you?

 

[TheMightyQuinn]

But it is quite impossible to run all that stuff for 5 -7 hours off of 2 x 102 Ah batteries!! I do not understand why this is even discussed and how the salesman can "explain" this?

 

[Grasmuis]

Well, 1500VA is FAR off from 3kW, nevermind 6kW... So you're not exactly comparing apples with apples now, are you?

Ok, for about R3000 extra you can buy the 4000Va unit. I'm not sure why you would buy a 6kW inverter with only 4 x 100Ah batteries, you can only run for about 15-30 min if you draw 6Kw from the inverter.

Edit : Sorry its R5000 extra for the 4000VA.

I doubt the batteries can even discharge fast enough to support that even if you tried.

 

[Grasmuis]

4000VA/3200W inverter = R9160
Battery Cabinet + Cables = R760
100 Ah batteries = 2 x R1700
Total = R13320

Still R8679 cheaper.

 

[savage]

GeForce G210 nVidia Graphics Card - R427
NVIDIA GTX 980TI G1 Gaming 6144MB Grapics Card - R12,700

They are both graphic cards, and they both allow you to see what you are doing on a PC screen. Is it the same thing? Hell no

Again, there are PLENTY of ways to do a lot of different things. Requirements are different, budgets are different, loads are different.

Hook up a geyser to that and see how close you get to "5 - 7hours"..............................................

Amazing that you will actually try defend these people. You seem to leap to the defence of anyone to do with alternative energy or electricity without any thought? Is it just because they are in the same sector as you, some big all electricians stick together thing? If so no wonder electricians have such a bad reputation, you should out people doing bad things not try protect them otherwise your field deserves a terrible reputation.

FWIW The picture looks pretty much like a DEVEL 3000W that they have stuck their own sticker on, available from SAEG for R7000 even less if you import it yourself or shop around.

Why you are disingenuously trying to compare this to a fully wired in Axpert in an attempt to defend these people is beyond me.

Is there a 1% chance that they are actually selling something worth that much money, like a properly wired in Axpert, sure. However given the hilariously undersized batteries and various other things (geyser, seriously?) it is infinitely more probable that its a R7000 Devel with 2xR1000 batteries being sold by someone who wants to make easy money.
