Lets be very practical and go back to basics.

From physics, the relevant formula to this matter is
Power (P) = Current (I) x Volt (V)
P=IV

The man has 2 x 100AH = 200AH on a 24V inverter connected in series.

Remember that connection in series, voltage increases nd current remains same.

Power =24V x 100AH = 2400Wh

This battery has the capacity to store 2.4kWh of energy. A charger must be able to produce this energy for the battery to store.

So what charger does he have? He has a 20A charger. This means the charger will be able to provide

P = 24 x 20 = 480w

It means that what ever his source is, whether NEPA or generator the charger will be drawing not more than 480watts per second and depositing in the battery.

The math continues
2400Whr /480W = 5hrs

The battery will be full in 5hrs.

It means that any source of AC supply, the charger gets to draw 480W.

In your case, you didnt mention the current for the luminous but i assume its 20A.

Power will be 24 x 20= 480w same as above. Your generator which is actually a 2000w generator (generators of 2500-2900va are 2kw while 3000-3700va are 2.1-2.3kw) will carry this load with ease. Like i noted in my last post, this will depend on other loads on the generator and additionally the state of your generator. Also, this power 480w is 24% of the capacity of the generator.

For the Mustpower which you said 48v x 30A=1440w. This is 72% of the capacity your generator, that is excluding any other load you might have connected to the home. This is not even taking into consideration the serviceability state of your generator to carry such a heavy load.

With this, i dont expect your 2.5kva generator to struggle to power that mustpower inverter especially if connected through your home with other loads and losses.

Wise speaking Mate,
I was about to explain same thing too,
But you took the letters right of my keypad, grin

I support all that you have said completely you said my mind,

Just to top it up a little if you don't mind, cheesy

Oga @earthrealm,
You have also spoken very well,
I actually like your view for being more practical,
But our calculations also are based on real life too.

Point to note,
When converting from kva to kw, a 0.8 power factor is noted,
And also when dealing with current we also work with efficiency due to heat/loss and length of cable which is varies to from 0.6 to 0.9

For your small Gen,
Of 2500va can actually produce,
2500 x 0.8 = 2000watt of power,
And let assume actually efficiency of the gen is 95% or 0.95
Which brings us to 2000 x 0.95 = 1900watts,

For your 4kva 48v mustpower inverter with 4 x 200ah batts.

Noting also, charging voltage is 14v x 2 =56v
And current is 30a
Would give a sum of 56v x 30a = 1680watts

Do note that dc-ac or ac-dc there is always energy/heat loss and not always 100% efficient because the internal component like the transformer and it's cohort sef go receive share for the power,
Thank you for correcting me on this part!

Thereby noting that your efficiency is atleast at 90% or 0.90
Would bring us to 1680w ÷ 0.9 = 1867w
The extra watt to this is known as payment for energy conversation or owo ile. grin

Now for your generator to last you without stressing it,
You need your load to be at 80% load
1900w x 0.8 = 1520w

Meaning that your Generator can carry 1520w load without going into overloading.

Now your inverter requires a starting power of 1867w and your generator can effectively provide 1520w of power without tripping off,

Now you see why your generator is coughing!

For your 24v 1500kva luminous inverter with 2 x 200ah batts.
Divide your bigger inverter load by 2 = 933.5w

Oga architectdre,
Thanks to earthrealm and adanny01,
A conclusion has been reached that small generator can't power your inverter ~~effectively~~ at all at all.

I was wrong for neglecting power factor and efficiency!

Kudos to earthrealm for practical insight!

army arena was the same place i bougt it,it worked perfectly while it did.Have an idea of the rough estimate of repair cost?

I don't really know bro,
But have you checked it for blown fuse?
There's quite a number of people here with blown sueor charger,
Hopefully they come out soon to tell us how they fixed theirs.

adanny01:
I will just add that he should note that this is just power needed to charge batteries exluding power need by any appliance connected to the inverter especially if the load will be on inverter mains bypass.

It means, that a tv, home theatre, lights or fan load during charging goes directly to the generator by mains bypass design.

Say LED tv 60w, home theatre 30w, lights 3 x 20w, fan 60w, laptop 60w in total 270w. Whether these loads are on the inverter or the entire house mains, they fall back as load to the gen if the gen powers the entire house.

Generator required must be above 560w + 270w =830w. This will be beyond "i pass my neighbor" generator. I would suggest 1500w as minimum.

True,
You are right,
1500w is cool,
My suggestion goes mainly if he already has a small generator,
But if he intends to buy any, he should good for generator with a minimum of 1500w power not peak power rating oo! grin

As for the load,
I already stated it in my post, thank you very much for further clarification!

_{^{Which is quite fair, so long you only use the generator with just lighting bulb and no much load during the period of charging the battery.

Just to be safe,
Anything abit bigger than a small tiger generator should be fine.}}

Cheers Mate!

I have a 2.4kva mercury inverter with 2 200amps batteries that ive been using for about a year now...im thinking of buying a generator to charge the batteries as the power supply is now worse. pls what size of generator will charge the batteries efficiently without damage?

Just think about it,
You have 200ah battery connected in series would give you 24v x 200ah = 4800Wh

But note that most inverter recommended charge settings shouldn't exceed 10% to 13% of the battery capacity meaning your 200ah would need at most 20a draw during charging,

So maximum charging current would be:
24v x 20a =480W

Meaning your inverter requires 480W of power to charge it batteries,

Smallest tiger generator is 800W

Meaning you would be using 480/800 x100 = 60% gen power

Which is quite fair, so long you only use the generator with just lighting bulb and no much load during the period of charging the battery.

Just to be safe,
Anything abit bigger than a small tiger generator should be fine.

Cheers!

Edit:
I just remembered that charging voltage is always higher than 12v, around a maximum of 14v x 2 = 28v
So considering maximum factor of 28v during charging would be 28v x 20a = 560W

I would leave you to do the remaining maths! grin

Use any gen you have and increase to a steady volt of 220-230

Bros is your smart charger suoer? - No it's not
If so, how long have you been using it? - Over 5months
And what's your load(probably In watts)? - Over 250watts
And how many hours does it last you when fully charged, - Over 10hrs
Was the battery brand new? - No. A 'grade A' battery
And also how long have you been using the battery? 5months Plus.
And again how do you maintain the battery? I charge it and that's all.
Do you top it up with water? - Water ke? Na radiator?
Thanks

Thank you very much kind sir for your amazing response!
This is exactly what I needed!

That water part I hear say dem dey top am up with water small small, grin

I have actually recovered a ups battery by using the **water method**

Calebeslove4u:
please house, is it safe to place my battery and ups ontop of the fridge? because that's the only place/height the hands of my kids cant get to. for fear of the battery shocking them

cc: ceejay

Well just placing it on the ground while kids are around could be very dangerous,
They might spill something on it or short the terminals of the battery somewhere an cause an explosion!

I advice you get it to a corner and barricade it by constructing a demarcation/housing where you have to lock it.

Because even on top a tall refrigerator,
Kids can be very curious/adventurous and still find a way to get to it.

I need help... I bought a 150ah Rita battery Nov 2016 then i could use TV, 2 ceiling fan and 2 bulb from 7pm to 10pm then 1 ceiling and 1 bulb from 10pm to 6am and over bar left on the inverter, but recently I can barely use 1 bulb and 1ceiling fan from 7pm to 11pm.
I read online Rita battery y life span is 10 years
can someone tell what is going or reason why this is happening

Probably it is discharged too deeply,
Or overchaged!

I have someone experiencing same issue,
The battery don fat for here.

The Bosses would brief you more in the morning

Cheers!
