saint2ace:
I have a prag 2.5kva inverter and 2 150ah Ritar batteries connected in series, but I've noticed a large gap in voltage on both batteries. When fully charged but with grid power on, one reads 14.22v while the other reads 13.45v.

When load is put on it there's almost a 3v difference as I've noticed one go below 10v while the other is still on 12.45v.

I have a 24v balancer hooked up to the system and both batteries are brand new, same batch and production dates.

What could be responsible, cos I've never since this before, but when separated each battery charges to 14.5v and maintains a relatively good voltage but when put together the wahala starts......
What is the function of the 24V balancer? Is there a 48v balancer for a 48v system? How much are balances?

NiyiOmoIyunade:
Have you already purchased all this BOM?

I see issues with a 180v inverter, a 180v CC and stringing 15 units of 12v batteries in series.

Best go for 48v inverter suitably sized as well as a good quality CC made for 12v/24v/48v on the battery side. There is a very good reason why most value and premium RE equipment peak out max 48vDC nominal voltage on the battery side.

Where I see issues;
1) Battery pack balancing with 15 pieces of 12v batteries in series. That is 15 potential points of failure on the batteries alone and the difficulty of finding a purpose built balancer or replacing a bad battery without changing the whole battery bank. This is especially true for 12v batteries but as you say you have tubular batteries there is hope.

2) 180v CC may be PWM and not MPPT as advertised. I expect a much higher operating voltage range with a CC designed to charge a 180v nominal battery bank - your mileage may vary.

3) 180v inverters tend to be those India origin inverters. I see them as little more than glorified UPS with generally subpar charging algorithms and poor surge handling capabilities.

If your purchases are not already locked perhaps the house can give better suggestions especially if you supply intended load, run hours and other parameters.
Thanks a lot for your prompt response. You have given me a lot of insight.
For your response:
1. How can i get a battery bank balancer that will suit my design.
2. My technician said same - that it is likely a pwm but another tech said YOHAKO brand has it. Are u suggesting i go for 192v cc
3. You are right, the inverter is indian but i am scared of the chinese ones that seem to fry at heavy load.

Only the inverter has been locked. Load is for a duplex, 1 freezer, 2 fridges, 2 AC (1.5hp), 4 standing fans,20 light points(15 Watts each), 16 cctv cameras, 1 pumping machine.
Can i use tubular batteries offgrid? Someone said i can't as it will give issues.

You did not indicate the wattage of the bulbs which will better inform on whether 4800WH will be sufficient backup.
That said I don't think there is need for the bold, get the felicity 48v 5kva instead and run 3s4p instead, if the 48v 3kva felicity can do 3s4p then that will be cheaper option.
Oga and the rest of the house, i am a newbie on solar matters but trying to do some investment in solar power (off grid).
30 x 380w tier 1 solar panels (mono)
10kva 180V inverter (sukam)
180 V MPPT Charge controller 80A (but I am still searching for 100A but its scarce unlessi order on alibaba but time is not my friend here)
15 batteries of 200ah each and 12v (tubular)
How best can I set up the panels in parallel and in series to harness maximum a available energy from the panels as I have observed that you guys are particular about how the panels are connected. What is the best way of monitoring my the performance of my set-up, any recommended monitoring device? 3S10P?
Note we plan use 4mm cable from the panel to the CC but i am skeptical about this but the technician says it is adequate since it is DC.
HealthRe: Tunde Salako: Doctors Should Examine Patients Before Suggesting COVID-19 Tests by danowena: 6:41am On Apr 06, 2020
hermesprogidy:
In an ideal situation, you would be correct. But do you know how much those PCR test kits for covid 19 cost? Do you know that despite all the noise about the FG releasing money to organizations like NIMR to fight Covid 19, not a single naira has come to them? The tests they are managing to provide pro bono is being supported by private foundations and not government, hence their testing capacity is very limited.
He spoke as an administrator living the reality of a resource poor setting. There's a lot going on under the table.
What he should say and call for is for support. New York have serious shortages, did they say people should not be coming for tests? Don't you see the governor of New York shouting for assistance and aids everyday. They need more doctors, nurses, test kits and ventilators and are letting the public know this. So,the prof ought to call for support and state it clearly that they lack testing facilities,PPE and capabilities to meet up with demand not what he said. We should all use our heads.

Fa44me:
Ahah, it's too early Mr/mrs. The prof. Said before people are sent for Covid19 test, they should be examined. There are other tests doctors can run on patients apart from CVID19 test. To me, the prof. had made a good point.
If the covid was a normal ailment, perhaps. But with a contagious disease? No, you first eliminate the possibility of it being that contagious disease before addressing any other suspicion otherwise the consequences are exponential. COVID-19 is not malaria or typhoid.
HealthRe: Tunde Salako: Doctors Should Examine Patients Before Suggesting COVID-19 Tests by danowena:
seunfly:
Are u a doctor or health practitioner?
I guess u are not and that is why u are talking like that.
In medical diagnosis u ruled out suspicion by doing examination you could do before going extreem especially if confirmatiin of extreme could take longer time to get.

Imagine somebody suffering from simple but emmergency issue and you refused to assess that person u just refered him straigh for convid 19 test which may take days to get the test done and another days to get the result in Nigeria, the patient would have died before result is out and any well trained doctor would have avoided that by properly examining the pateint.
This is where you are showing your ignorance and bringing the validity of your certificate to question (If indeed you are a medical professional, your competence is highly questionable). This is why some doctors in Nigeria do guess work instead of dotting the "i's" and crossing the "t's" by doing proper medical diagnosis and tests rather than guessing. I repeat and read it very well so that it sinks in : Tests are part of the diagnosis process to either confirm or refute what is suspected. I don't know how silly people can be. You need not go to medical school to know that it is better to confirm or eliminate a suspicion. By so doing, you know you next line of action with assurance.

Now to your emergency issue, which shows you know nothing about medicine. What you do is stabilise the person and treat for whatever you suspect but you do not prevent the person from going for the relevant test. Like I said, you are not in the field so let me give you a simple example to drive it into your head. A man is rushed to the hospital with high temperature (recurrent fever on a daily basis), vomiting, stomach pain and complaint of dizziness. This man even tells you that he slept in a mosquito infested area a week ago where he was bitten by mosquitoes. Now in this case, there are number of suspicions:
1. he has malaria
2. he has food poisoning (stomache pain)
3. he has ulcer (stomach pain)
4. he could even have appendicitis
5. Any other thing.

So what do we do, we ask him to go for tests without administering anything? No.
You take his vitals and proceed from there.
What can address temperature? a brand of paracetamol.
The stomach ache can be by a drug used to stabilise the PH level in the tummy (don't want to go into drug names so people don't go self medicating).
The dizziness can be addressed by passing an appropriate fluid to his system (drip).
You don't just treat him for malaria because you think it is most likely malaria.

You send his blood sample for test for malaria, ulcer,appendicitis and any other suspicion. When the test result is out is when you now commence proper and direct treatment to address whatever the test says is wrong.
If truly, you are a medical professional, you need to go back to your basics. I am sure you are not in the medical field or you are a pure charlatan.
HealthRe: Tunde Salako: Doctors Should Examine Patients Before Suggesting COVID-19 Tests by danowena:
See this man that called himself a professor speaking like a layman. So doctors should examine patients critically before refering them for malaria tests as well? Professor, just incase you have forgotten, the tests are meant to either confirm or negate suspicion of an ailmemt. It is a vital part of the diagnosis process.
Despite the number of negative results in the US and Uk (as examples) did you hear them advise doctors to stop referring people for tests? I am glad you mentioned that some were postive. What if the doctors of those positive ones allowed them to roam about? Professor, take your time o o. This is not the time to say rubbish if you have nothing tangible to say. Don't risk the lives of people because you want media attention.
Your statement is grossly stupid and very irresponsible.

I am a member of mfm . I don't place emphasis on celebrating Christmas neither am I against people who do celebrate.but we live in dangerous times and precaution need to be taken.A neighbor of mine threw a big party on Xmas and shared food to everyone.in no distance time anoda of my neighbor called me if I hadn't collected any food gifted by the neighbor celebrating and I said no coz I just packed in newly.he later narrated to me that he is a strong confraternity member and does so everyyear to syphon pipu blessing for the new year.this said neighbor is still owing a year's rent.so tell me why is celebrating Xmas so important instead of paying his rent?food for tot guys.
If he is syphoning blessings truely, how come the blessings he syphoned are not enuff to pay his rent? Or are u implying that all the people that have eaten his rice aren't adequately blessed? Please stop listening to people's opinion and seek God's face about matters. That man may just be using his last cash to cook rice for neighbours in the spirit of the season yet some ingrates will quickly attribute to a diabolic ritual for blessing syphoning. angry
Where is ur empowerment as a Christian to pray and sanctify food even those sacrifuced to idols? huh

RomanceRe: Six Tips How To Approach & Date Single Military Women by danowena:
Nice write-up. Just a few comments having dated military ladies in the past.
1. Forget the uniforms, treat them the way you will treat a normal lady (with respect)
2. Present a good appearance in dressing and communication.
3.Praise the efforts of women in military. Identify their challengea and think of solutions.
4.Demonstrate that you can meet and cater for their needs both financially, emotionally and sexually. They are just women in uniforms and sometimes are lonelier than their civilian counter parts. They have needs like every other women just the way they bleed monthly like every other woman.
5. Respect their schedules and align your dates to their convenience.Let them be the ones to invite you to their barracks or homes. If you are good enough, they will want to show you off.
