Dam5reey:


So Please go and Remove that claim for 1w idle consumption from your post.. it was a conclusion based on assumptions and not a correct way of testing...

It's misleading..

It's should be 6w to 15w based on few I have tested

As cheap as souer 1000w is it can never take 6w.
Hope I can use this to checkmate power
P=IV
P= 0.15A(or less)× 12v
= 1.8w

Don't mind me, I'm just passing by.

Like someone said above, the battery brand you bought is very suspect and more likely where your problem is coming from.

Do the load tests people have advised you to do with the bulbs and other heavy loads. Also with your setup, you shouldn't really be discharging more than 8-10 amps (96- 120 watts) an hour when not charging as that is the poverty attached to lead acid batteries (c20 rule for 200AH, thats if the battery is even rated up to C20!).

Anyone buying batteries should always have at least an independent multimeter (1k5) to be able to check voltage for yourself especially when brand new. So if you follow the above and pull 50 amps in 5hours and your setup reads less than 12v, then your battery capacity has been misrepresented. Though it would probably be best for you to separate the batteries and test individually; thus pulling 25AH in 5 hours from each battery.

To be honest, I think you should return the battery if you can still get your money back. Go for tried and trusted brands people have used on this forum.

Kindly suggest what trusted solar battery brands

Bros u too dey authoritative
Not good.
We are not writing exam with it.

I don't understand what you mean.. So I should I agree with False information even when you have stated how you arrived at 1.1 which is totally Wrong..

Accept you are wrong and take the 1.1w information OFF..

ewizard1:

Because it's on directly on the battery's path before the switching starts. The button/switch to open the gate to the inverter is inside the inverter.

The consumption exist just for the charge up. When its filled, that's all.

That's why after the first spark, if you remove the battery for like 3 seconds on reconnect, it doesn't spark. Because the capacity is still charged.

Assumptions, Get a DC meter and Revert..

lolz, wahala no de finish. @dollarnaira, @ dam5reey is correct, there is no way, that inverter will consume just 1.1w. u need to a DC meter with shunt, to accurately measure the idle current and the efficiency on load.

PLEASE HELP!
3.5kva 48v Felicity Inverter, 60A TriStar Mppt and 4pcs of 230Ah Genus tubular batteries with balancer installed.
Since the batteries has been on ground for months, I knew the batteries will be suffering from sulphation. So i decided to set 15.7v for equalisation and 15.1v, 14.9v, 14.5v and 14.7v were shown on Voltmeter.
After 3hrs, the readings returned to 14.4v, 14.1v, 13.8v and 14.1v.
This readings maintained till 5pm due to dull weather.
I went out by 5pm and returned by 6pm to see the readings 12.3v, 12.4v, 11.9v and 12.3v.
I've Not placed any load on the system since morning.
Though I don't know the idle power consumption of this inverter but I'm worried about the sudden drop in voltage.
Is it because the battery wasn't floating?

Could battery deviation has a role in voltage sudden dropping?

Since I've equalised it today, do I still need to equalise it again tomorrow?

odimbannamdi:


As you progress on this journey, you will realize that peace of mind is GOLDEN. Even when you want to troubleshoot, you need to have a "base", which is a confirmation that you are sure of certain aspects in your system, and a PSW inverter will give you that confirmation/base to a a large extent.

Also, it is not out of place for you to have more than one inverter. It is a good idea to have an extra one for contingency. So close eye pass PSW inverter.

Confirm.
But na the money to buy PSW be the koko.

This is the system.

Bro I once made the same mistake you made, using my AC wattmeter to give me the idle consumption of my inverter, which came out negligible before it now dawned on me that there was no way an ac meter plugged into the inverter would be able to measure the dc amps that the same inverter was pulling from my battery.

I ended up getting a DC meter & shunt and voila I found out my old school inverter was pulling 20-28 wats on my battery for simply being on!! Thats 2amps down the drain and like Dam5reey pointed out its probably gets higher depending on how high the load it is benchpressing becomes.

Nowadays, my dc meter is used to determine all load, I hardly use the ac for anything.

Its clear that you were just honestly asking and he (for some reason) just couldn't seem to decipher that you were being honest in understanding your mistake.

Let it be and take the claim off.

@Dam5reey, pls look at the tone of people when you reply, he was being sincere and this could have been cleared up in just one post really, if you had noticed the sincerity. Be calming down.

Well both Amaron and Fullriver don't really have fakes in the market and are dependable and less costly, so I would suggest them.

Ritar is also a good brand and very available, but the fakes are all over the market.

Stay away from anything sold by Simba for now (Luminous, Genus etc.)

Also if you see any good deals, just post on the forum beforehand and people will be happy to give you there experiences with the battery brands (which to be honest is priceless advice).

Someone spotted an error in a public post you shared on an informative forum, called your attention to it. You also checked and found same to be false. But you can't honourably accept to change it but instead claim he's arrogant? You don't see how you're being arrogant yourself? Perhaps the only one being arrogant wih a wrong post?

You're even asking him to go tell posters of very old posts to also make changes.

Na wa o. It's not all that serious stuff here. Not as though we'd forget how helpful you have been on the thread if you accept to change it. It's no big deal.

Good brand , American made if I am correct.

Should also be more pricey than all the other brands I mentioned to you earlier.

With the kind of interest you are showing you may have to spend quality time reading this thread from page one!

It has to do with your battery's behaviour under load and off-load (rest voltage) reflecting it state of charge (SOC).

To simplify, this chart will give you an idea, however you will notice that both readings (or SOC/DOD) you got still corresponds to about 50% capacity drained off your battery.

Wàhálà no dey finish.

You may both be right, but it's permissible that a superior argument carries the day. And I think his was an honest error which he will be willing to correct going forward. The rush to determine consumption as a golden basis of solar usage can sometimes bring out that mistake. But at some point, you get to know that the wattmeter function starts at the AC output of the inverter.

1. Did we learn everything you know about solar in one day?

2. Can anyone and especially to those we see as experts here swear never to have asked or sought clarification here on particular challenges in the solar journey, even while donning their level of mastery?

3. Do we believe that we've known it all and can NEVER need clarifications from anyone here again?

4. Were we dressed down by any respondents here when No. 2 happened?

5. Would we like to be dressed down when the opposite of no 3 happens?

6. Do we even believe that it can be proven that 2+2 does not equal 4, either now or in the future when an overriding superior theorem is proposed?

Four centuries ago, it was an error, nay, a crime deserving death to say the earth was round because the "fact" then was that it was "flat". And the person that proposed it then "based on his findings" was silenced.

Few months ago, my ward came home to say according to her teacher, we have nine planets (these were the "facts" we were taught almost three decades ago). But I corrected her that one has been removed is no longer fully qualified to be termed a planet, hence the current eight. I carefully added that when she gets to school the following week, she should tell her teacher, not emphatically but suggestively, that "she thinks" we have eight because my daddy "thinks" so too.

Now that was a less condescending way to pass across the currently presiding fact and I'm pretty sure that teacher will not feel slighted and will at her leisure verify that "suggested" contradiction to what she believe held true. Everyone goes home happy at the end of the day.

I (and most likely majority of us here) was exposed to the Nigerian system of education which takes everything "as a fact" and does not encourage research nor admit possible contrary opinion. It became worse while being trained as a physician in the tertiary level because then you were expected to see your teachers as a demi-God that can make you if you kowtow or mar your future if you try to prove smart. An adventurous intellectual will be significantly limited and restricted under such conditions.

Exposure to the west gave an entirely different scenario. There, if a professor asks what 2 plus 2 is and a student responds 3, he (the teacher) will likely say to the student, "that was a nice try, but just a little off the target. How about we try 4, cos that's what I know it to be".

If by any chance of luck, 2 plus 2 has recently been accepted as 3 without the professor knowing and the student insist on his answer, he will simply respond that he would love to learn from that student why the answer has to be 3 instead of 4 that he knows.

I came back with this mentality and it has greatly and joyfully positively impacted my interactions both with everyday acquaintances and with specific meets.

@dollarnaira. Now that the error about the watt meter usage has been known, I think its only fair to put the more correct ratings especially for the sake of newbies who wants to purchase from you.

Forgive my diatribe everyone, I just can't help passing thru without chipping something in.

Please, I really need your help

Nice install.

I don't know or is it just me, but I like to make sure my Inverter is as close to the battery as much as possible so that the shortest possible cable connection is needed.

I believe the battery could have better been placed below that busbar which will ensure a shorter distance rather than another 2 meters from the busbar. Also it would ensure better aeration and noxious gas dissipation at that position rather than the current position where it is almost going into an enclosed space.

Except maybe to avoid corrosion of the other components from gasses being produced from that kind of batteries. That may justify that extra distance. Perhaps the installer had that in mind.

If you have a 12v charger, consider paralleling all the 4 batteries and charging it overnight. It once solved an issue a friend had with his four 200ah lead acid batteries.

But if after this you still continued having different voltages, you may consider running a battery test as one or two of the batteries may be failing.

A crude way to run a battery test that I've seen work several times is to fully charge the batteries, put a load of about 500w on the inverter and wait for the inverter to indicate battery low, quickly measure the battery terminal voltage. If any of the battery dropped to below 10.5v, you may consider such battery bad.
