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......

I hope this helps.

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.

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.

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.

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.

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.

Please, if you are Corps or prospective corps member, verify the distances of these places this op has mentioned.
That Itele, Ayobo that you're looking up there is a place where you would feel you're in real hell. That place is far like mad and the last time I was there, that area has not been electrified (NEPA has not run wire to that area, no electric pole, no nothing).
Again, don't just think, oh the rent is cheap and jump to rent it.

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.

The Redeemed Christian Church of God CRA Nottingham was blessed by Ian Fisher, the M.D. of Bonningtons (

with a Telsa Model X donation as a lead car to welcome the General Overseer, Pastor Enoch Adegboye’s first visit to Nottingham.
