Abdomox:
I have a 1.5Kva 24V inverter (Treshold). Pure Sine Wave HUPS was written on it. See picture below.

The batteries (Luminous) were bought new same time, 10 months ago from Simba in Surulere, Lagos.

Abdomox:
Please help on this situation.

I have two 200AH battery, and I observed that when it shows low battery, one battery will be reading 10.5V and another 12.2V. They were both charged fully.

My concern is why is the inverter not drawing consumption evenly from both batteries. Thank you.

ojeysky:
When you parallel a 12v 100AH with another 12v you get 12v 200AH

ojeysky:
So if the battery is 100AH, then it means he has a 200AH 12v connected in series to a 100AH 12v. In that case, the fire he is playing is the one that will turn all his investment on the battery into a waste in near future.

acunon:
Like how much sir?

odimbannamdi:
Interesting expose.

The ones you bought for 72k, how did you manage it? Did you abide by the golden rule of not draining the batteries below 50% at any one time?

NiyiOmoIyunade:
I second Eleojo23 and Essegis here - as you say you only use this system occasionally to power one single load (freezer) - I reckon the freezer will take worst case 200w per hour when it runs off the batteries or solar - 640w of solar panels should easily power a 200w load, also the C20 discharge rate for 3 units of Ritar 12v 105Ah is about 190w watts per hour so both your PV array and battery bank are already adequate.

As you stated, you only use the system occasionally to power just one freezer so any deficits e.g insufficient solar charging would be easily remedied on subsequent days when the batteries are not being drained by the freezer.

Your system as it stands appears sufficient to meet your needs - doubling PV capacity and adding new batteries is just a waste of resources except there is some info missing e.g there are other loads or the freezer is a power guzzling demon (I once went to a client whose shop had a freezer for keeping icecream fresh and I measured the thing consuming over 1,000watts range for a straight 12 hours This was not a huge freezer mind you, just power hungry. The customer wanted an overnight backup system for the freezer for a total of 400k spend - I jejely ran away as the woman refused to understand all my explanation and preaching.

NiyiOmoIyunade:
'...Then Jesus answered and said - Blessed art thou Simon son of Jonah, for flesh and blood hath not revealed this to you, but my Father in heaven!....'

This your bolded words should be engraved in gold lettering on a marble plaque and placed in a prominent place in the heart and mind of any and everyone who does anything with batteries, inverters, solar and renewable energy in general.

alstacs:
I am sorry house. I noticed that over the past years there has been a wide variability in the prices of deep cycle batteries unlike in the past when the prices were somewhat close.
For instance I see 12V, 200mAH batteries go for between 80k to as high as 180k each. What then guides people's informed choices on these batteries?
Why are some so cheap and others over 100% above the cost of others?

ceaser:
Thanks.

Well, yours is fangpusun. But this is PowMr. And shit just prove to me why it's not in the league of Fangpusun.

I connected the three in series. Shit can't even take in 120v Voc. It momentarily shows 117v Voc and then the charging indicator refuses to show "solar input" sign. Knowing what that could mean, I immediately shut off the DCB to prevent damage to the CC.

I then connected two panels in series and this yèyé controller picked up working. PV input at that point was 65v. To determine it wasn't just an off thing, I repeated 3s again and same scenario was replicated. Now I have put it back in 2s and one panel is redundant. I now get 450 watts, 200 watts short of the 650 watts I record on the 50 amps PWM that it replaced. Of course the PWM was on 3p.

The system is 24v.

Apparently in order to prevent damage to itself from over-Voc, shit first senses the Voc which was the 117v momentarily recorded and then it determines it it should allow solar input. That may be a desirable feature but this performance is really short of the 150v Voc specified for it.

Another reason I may still forgive this CC is if it will not replicate this nonsense in a 48v system. Perhaps if it senses the battery voltage as 48, then it can allow that 150v Voc to go thru.

In the meantime, I am sorely vexed with this thing considering the fact that I have two of it running a 24v system and this new install was actually one of two units I purchased which was delivered few days ago.

In the connection process, I also lost a solar input monitoring meter that I forgot was maxed out at 60v input spec. I just placed the 117v on it and thing smoked right away.

I may now try considering trying out the 60A version of its rival MakeSkyBlue that I have to see the performance. If it meets expectation then goodbye to PowMr and I will seriously shout out this information on the seller's store review.



By the way, your fangpusun is 12v/24v spec, right?

Hello Sir,

Let me buy and ship for you next time. Cheaper and reasonable delivery time guaranteed! You can chat me up people for quotations on your china purchase and deliveries!Thanks

it is a tank! One of the most reliable SUVs built by Toyota. Personally I prefer the models with V6 Engines, engines are super reliable if the right maintenance sequence is followed, it also tolerates abuse a lot

Please i need help to understand this as a layman.

What make a charge Controller function as a 12V or 24V spec

Is it when you have a battery bank of 12V then it function at that level or 24V and function as same?

Or is it that, same way u connect battery in series to achieve 24V you can also connect panels in Series to make the Charge controller function as a 24V

Max. PV voltage: 50V

But can take 750w for 12V
And 1500w for 24V

This confuses me

Won't the Max PV voltage exceed 50V on 1500w panel arrays

With the 1500w 24V setup panels and charge controller can u connect a single 12v battery without any issue.

Make una help me explain abeg in laymans terms

so, am planning ahead about building my house, am considering where best to locate the power room cum study in a duplex.
i am thinking of having an extra room in the duplex dedicated solely to power/inverter battery installations etc. and the space will also serve as my study. since am not sure yet of the type of battery i would be using, but likely 12 to 16 pieces or equivalent of 12v 200ah fla batteries, wi would think such weight would be better suited on the ground floor, and not subject the decking to the stress of carrying such a dead weight, however,..i would prefer my study to be upstairs, hence my dilenma. so hoping the house can throw useful suggestions on what they think is the best location with reasons.

thanks

The TCL that consumes 135w at full blast may be okay on only one condition: if it has "energy saving" option. With that option, once activated, the consumption may drop to as low as 25 watts depending on the size of the TV. 55 inch Hisense smart that is 125 watts at max consumption drops to around 25 watts at highest power saver. I use 60% power saver and that consumes around 30 watts. The remaining 100 watts can better be channelled to powering other vital appliances instead of just wasting it on TV alone.

PLEASE DO NOT PURCHASE THAT TV (ANY TV FOR THAT MATTER) WITHOUT BEING SURE OF THE POWER SAVER OPTION.

I know most large screen LG, Samsung and Hisense have that option. But I can't tell for TCL since it is a new brand trying to penetrate the Nigerian market.

Pls what do you know about Luminous Eco volt inverters. Someone wants to sell a used one and I’m interested. 3.5kva for 60k.

What's the capacity of the Scanfrost freezer and what's the energy consumption?

earthrealm:
Anybody using a samsung inverter fridge?
thinking of going against my better judgement, and going for a samsung frost free inverter fridge, seems all manufacturers except haier thermoccol have gone the route of frost free.

nigeria with epileptic power supply isnt so ideal for frost free fridges, however with the 30w consumption of an LG inverter by JUO, i think my modest setup can handle the fridge running 24/7.

LG burnt me badly in the freezer i bought 2 years ago, very poor chilling and doesnt retain cold, 4 to 6hrs after power off, freezer chamber is almost lukewarm!
thus i decided not to go near any LG fridge or freezer again

theoilguy:
Useless panels.. Degrades significantly after one year of production.. Not worth the time and effort...

Stick to tier 1 panels like Canadian solar if money is no object.

Las las, u ll be glad you did.

Good evening Boss
Kindly help with this .

Ever since I bought my corolla 2004 more than 5yrs ago, Anytime I just full my tank in the filling station, I will turn the key to start it, it will appear to start, but the engine goes off, then I start it again, it will ,I will then fire, later it stops after like 20secs, until around 4th time of starting it..
When i fuel with little quantity it has a less severe issue.
Initially I overlooked it but for the embarashment
All other times, the engine starts on one kick only when i fuel it.

Someone said it's fuel filter, I have changed it yet no improvement.
Someone said it's fuel tank, I got a new one also because the former was leaking.

What do I do Sir
