Oga KieKie,

Please are these pictures of one single location or two different places? I see what appears to be your trusty CyberPower 3.5kva inverter in one picture but in the other picture with the battery monitors, I see something that looks Victronish and from the size dimensions looks more like an inverter than a a CC - I could be off though because all the pics are rather darkened.

Do you get any assist from the Grid or Gen overnight? It appears with your AC on overnight, you are running roughly 1.1kw on 6pcs of 12v 200Ah batteries (14.4kwh of storage) so you would both be exceeding the C20 discharge rate and most likely going below 50% DoD as well if you get no Grid or Gen assist.

If you are getting no grid assist, what does your battery voltage look like in the mornings after you have run your AC overnight?

Second snapshot shows refrigerator timer switch deactivated by 10:30pm, room split AC been running for 45min approximately. AC runs mostly within 25-28° overnight depending on weather, yet batteries don't go below 24v .. PHCH or not, no worries as I get within 55-65a mppt cc daily to float batteries back before dusk!

It has been green efficient energy all year round

Yes that's a Victron 70a mppt beside the monitors and a 24hrs USA online smart inverter which triggers the refrigerator programmed timers on 24hrs basis and hasn't gone off for about 4 years counting. I am partially offgrid as our grid supply is highly epileptic! I mentioned a while ago, my die-hard cyberpower only comes on basically for opportunistic high wattage loads, I treat it like a baby because the service parts is very rare .. Yes you saw that high kw load rating because all those loads listed was ON and AC only came on when Fridge went OFF. Flood led and AC overnight reads 800-830w , only when AC compressor kicks in since am on 25-28° temp settings. When AC compressor cuts, I get roughly +/-70watts max on system display! Worst battery volt i have seen overnight is 23 / 23.5v mainly during dull weather which doest bother my bank at all, my inverters set depth of discharge is 21.5v min but I have never experienced low battery alarm nor shut down because i and my household are very practical about load management ...
Note:refrigerator compulsorily works 12-6am overnight , and intermittently comes on for an hour or 2 by late evening on timer settings. Cheer's

Thanks Oga KieKie,

Please tell us more about the inverter bolded below.

...24hrs USA online smart inverter which triggers the refrigerator programmed timers on 24hrs basis...

Also, are the timers integrated into the inverter or they are normal external devices?

I would assume this inverter is low wattage or at least smaller than your CyberPower since you still prefer to use the CyberPower for your larger loads.

Finally how are you able to get a split 1.5hp AC (non inverter type) to consume 800 to 830watts? Or is it a different AC in use now?

Kilode! How can you say it's similar to this? Depending on the usage conditions and your ability to test, used batteries could be a good bargain.If you know the seller, the ultimate test is to run it for a day(24hrs)then pay

Oshomo12:
Buying used batteries is similar to you crossing an eight lane high way blind folded(99% chances of it not ending well).

Exaggerated performance....If you know you know

Seconded!

The one sure way to test a battery is by a sustained load test. Under a suitably calibrated load, a battery's true capacity or lack thereof will quickly show

Oga Pharyn,

Well done and more power to your elbow! My only request is that you teach me (in private) how to land clients like these

One such job on a monthly basis should do me very well indeed!

More power and more grace Sir.

He can get away with it on the other groups that are less informed but certainly not on this group as the gurus here can easily see through any exaggerated claims

I am sure you he will not respond again after you caught him out. On delivery supplies indeed

Most of the good options (value & premium inverters and CCs) are within the 12v to 48v range.

Given that your batteries are 12v units you will find best battery balance at 12v but your maximum efficiency at 48v.

Borrowing from how 12v batteries in parallel stay better in sync with each other, one may contrive a similar arrangement with multiple parallel bank 24v or 48v battery setups by creating additional parallel links between each position in each bank. I will post a diagram in a bit.

This solution is not a cure all though, it solves a part of the problem but still leaves something unsolved. It has worked well for me so far vs. doing the conventional approach though.

olaade21:
You have 16 units of 12 volt 200 AH batteries. Simple Math. 16 x 12 volts x 200 AH = 38,400 watt hours period. You can arrange them as:

12 Volts: putting all 16 batteries in parallel strings which gives you 12 volts @ 3200 AH or 12 volts x 3200 AH = 38.400 Watt Hours

24 Volts: 2 in series and 8 parallel Strings which gives you 24 volts @ 1600 AH or 24 volts x 1600 AH = 38,400 Watt Hours

48 Volts: 4 in series and 4 parallel strings which gives you 48 volts @ 800 AH or 48 volts x 800 AH = 38,400 Watt Hours

96 Volts: 8 in series and 2 parallel strings which gives you 96 volts @ 400 AH or 96 Volts x 400 AH = 38,400 Watt Hours

192 Volts: All 16 in series which gives you 192 volts @ 200 AH or 196 volts x 200 AH = 38.400 Watt Hours.

See anything in common?

Series Voltage Adds
Parallel Current Adds
Power always adds. Every battery is 12 volts x 200 AH = 2400 watt hours. You have 16 of them or 16 x 2400 watt hours = 38,400 watt hours

Here is the bad news. The only good configuration is 196 volts. You really screwed up using parallel batteries. In about a year or less you will learn this lesson the good ole fashion way loosing lots of money when you have to replace the batteries. Don't make that mistake twice.



Saw this on an online forum and throwing it up to the Ogas in the house. Which do you believe is the best setup.

good evening all, compliments of the season!!

I want to make a suggestion. I propose that the markerters who spam this thread with a long list of products should create a new thread & list all products/prices & update when necessary.

Then they should drop the link to that thread here. "contact us for your Solar need, for avaliable products/updated prices visit http:/......"

CAROLYN19 doesn't spam, he/she leaves a short message & that's it with occasional repost.

Its insulting that despite the outcry of contributors here, folks are still bent flooding the pages with adverts

olaade21:

Beautiful. I like your explanation. What do you propose as the best home solution. 24v/48v, Series/Parallel for a 12v 200Ah battery setup.

If you're starting fresh, 48V is really good. It's the lowest current option for the typical home system. High current is the bane of electricity transmission because cable resistance is fairly constant. That leaves you with voltage to mess around with thus lowering your current. In addition, 48V will always require fewer strings if you use the same batteries (as opposed to 12v and 24V).

Think about your needs. If a 48V system will work for you (including consideration for DC devices or not), please go ahead with it.

Often true but ... I have on occasion seen one bad cell in a single battery promptly spawn bad cells in parallel batteries. Case in question had a bank of 4 batteries in parallel. Things were good for a long while so I went to sleep. I didn't notice until 2 of them had irrecoverably bad cells. I went on to separate into 2 banks of 12v x 2 in dual parallel config. I believe I made a post about it on this forum.

From that experience, it became pretty apparent that 12V batteries are cool but they're just 2V x 6 batteries hard-wired together in a single string The moment you run them in parallel, you experience the same issues as 2V x6/4v x 3/6V x 2 batteries in parallel without the benefit of isolating the bad cell without removing the entire battery. If you believe in God, you might need to pray your bank doesn't develop rogue cells.

The best config then is 2v(a cell) in series to form a battery. Thereafter continue with parallel and not exceeded 3strings.
