Thank you for your response. It's actually 2 transformer according to my supplier. Here is my observation. I charged(displayed) charging for 12 hours with 3.5kva maxi generator for 5kva inverter 48v, 200ah, 4 tubular batteries, and after loading it, it only lasted for less than 2hours. Meanwhile, when am using only solar panels it last for about 5hours for same loads. See the attached images(note from the images,I was using ups inverter before, then I changed it to kartel. Still same batteries) just to clarify that. Thanks

If its a hybrid, most likely.
If its a transformer based and in good health, most likely as well. However if your inverter has adjustable charging current setting, you can lower it til the gen can carry it.

For example, my old 4ka 48v mustpower transformer inverter, my 8kva gen charges it ok at max batt charginf current of 31amps, but when i use my 2.8kva gen, i have to reduce the charging current to 7amps ,if not the gen will cough and die

Hello house, I have a question. Can 3.5kva generator charge 5.0kva inverter(48v,200ah, 4 tubular batteries)? Or what's average generator I can use? Thank you all in advance

You need minimum of 6.5kva to power a 5.0kva inverter efficiently.

Thank you for your feedback.

Your gen output may not be clean, steady or above 220v or correct frequency.
All these 4 factors must be ok, b4 a gen can charge an inverter.

I have a friend who has similar complaint, when i went to investigate,. Gen output voltage was 190v and unsteady.
From experience, once gen output isnt upto 210v, the frequency will be below 50hz. And most inverters dont work optimally when frequency is below 50hz

My inverter behaves same, gen, nepa, solar charging

2ndly. Since your inverter is transformer based, then only hope of your gen being able to charge it a bit better is if you are able to reduce the inverter charging current.

I think GBM and Sunfit make 75ah deep cycle batteries.

At 50% DOD, he shouldn't expect anything more than 6hrs max.

cc: Lovelynife

hello house, please what can I do to my 2pcs 100ah GBM deep cycle batteries connected in parallel with 1kva ipowerplus inverter of 6month use that has drastically reduce run time to about 1.5hours on about 80watts load?

Is it the batteries that are 6 months old?
If yes, then something is wrong. Were they bought new or fairly used?
How do you charge the batteries and what is your charging current?

Note: GBM is a cheap brand so this is bound to happen even if you do everything right.

I have dedicated the GBM battery I have to handle only lighting because I noticed the voltage drops drastically under big load. The battery is 15months old and the resting voltage is now roughly 12.4 as against 12.7 at the time of purchase.

What was the voltage after the 12hrs but before you switched off charging source? If it was 50v as indicated on the picture then the batteries did not charge at all.

Na all this kind thing Ojeysky no dey like see. An under utilized battery.

Ever since I installed my hybrid bought from Futurenix and interchange the battery banks on a daily all of them just dey enjoy life like Airtel *444# advert. On their off days the CC don't even work at all. Looks like it's time to go off grid fully, or what do you all think.

New to this thread. Kindly show me some love.

What will the cost estimate of a complete solar system.
2kw ....2 battery system.. solar panels etc.

Very efficient, I have seen for a 70inch LG drop from 130W to 105W to 90W using just eco mode and drop to 70-60W on further reduction of brightness.

Even a conventional TV can reduce consumption by playing around with its brightness and all that.
Sound power consumption is a little negligible

Mine can do 70w,50, and 30w depending on the level of eco mode chosen. Brand is Samsung.

Hello sir, see the attached of the voltage after switched off of the generator(12hours)..before loading

That's impressive, is it a smart TV?

Na me oo. That thing is working wonders. I especially love the times it shows full bypass from solar to feed the house straight.

Only downside na the WiFi monitoring head no correct. As Chinco e just dey do as e like.

Harbeybancity22:

Okay I see it's 55v from the CC (the 52 on the inverter is freq) and what did the voltage drop to when charging was stopped? Can you also toggle the inverter screen to see your typical load(in watts) on the inverter

Thanks.
Which battery do you recommend?

We use Shoto brand.

This is to say many thanks to those handling this thread, you've made solar energy easy to understand. Also permit me to appreciate a nairalander I met on this thread.

We discussed and he earned my trust with his high level of professionalism. Very hardworking and trustworthy.

His handle is @olopan

Once again, God bless you all for keeping the knowledge sharing alive!!!

pls help me choose btw these options.

1. 4 units 12v 200ah quanta /thundervolt smf batts .about 600k
2. 48v 200ah felicity lifepo4 bank, abt 700k

3.4units 12v flooded tubular batts, i see so many makes with slight diff in prices, is anyone better than the others?. genus, mecury, luminous etc about 500k

Good day to you all. For those in need of electric fence-wire or razor wire(barb wire) in their home, kindly check my signature for thread or contact details, you will be glad you do so.

4 12v quanta/flooded is not equal to real 48v 200AH Lifepo4. The question will be whether the felicity is truly 200AH 48v if it is then I will suggest you go for it but I know some people have found it to be 120AH.

ojeysky:
I have got 2 brand new BMV 712 with temp sensor for grabs. 125k each

Q/A
Is this the victron BMV 712 with Bluetooth features?
Yes
Is the price negotiable?
No price is firm Sir/Ma
Does the price include shipping?
No it doesn't, but I can waybill to any part of the country at buyer's cost.

Still available

ojeysky:


So the Sonoff CH4 8.8kw capacity with remote controls has arrived and in its original packaging.
Application scenarios:
1. CH1 control you lightens
2. CH2 your pumping machine
3. CH3 Security lights
4. CH4 freezer/fridge
Each of the CH has a 2.2kw load capacity.

Reach me if interested.

Still available

Appreciate the mention, Glad I could be of great service to you.
Welcome to the family.

Based on cultured experiments done by members of this forum on felicity, I'd say that go for it, assuming you are running it with an intelligent inverter.

Said the above due to it Lithium makeup.
So more years out of it over the L.A Variant

My own professional opinion though

Good evening, Do you have variants of these batteries available? The price you called for 2000Ah is pretty juicy, I'd like to know more

earthrealm:


24 x 130k is 3.1m for a 48v 2000ah bank.
Incountry price of 48v 600ah lifepo4 bank is Abt 3m.
40 x 12v 200ah quanta = 48v 2000ah is abt 6m
I would take a 48v 2000ah lead acid bank over 48v 600ah lithuims.

Wish the batts came in 6v 2000ah, would be a lot easier and affordable for a 48v bank owner.
I wonder the price of 2v 1000ah

i dont have an intelligent invertee, my inverter is YIY 48v 5kva with batt type selector, but no lithium profile listed.
is there a way, i could use it for the lifepo4 battery?

also if i have more funds when is the latest time, i could buy a 2nd 48v 200ah felicity bank to add to the first bank. do i need to use a bms to parallel them?.

@ojeysky, so members here got 120ah from the felicity, thats pretty poor. has anybody opened it, what kind of cells are inside? name and capacity

Yiy has option to set float/bulk so it should be able to charge lithium batteries though may not be as optimal, the cells are prismatic. I think @adausa may have more experience to share
