See ur ekuke drawing
I get it

ewizard1:

Better. So be aware that these heavy inverters has charger inbuilt. Your kind of inverter has models with in-built chargers too.

Timileyin1234:

Which heaviness u dey talk? How many kva e be

Timileyin1234:
Moreso, is that battery u use safe

There are no disadvantage really. But normally a 2.3 or 2.5kva should use two 200ah 24v battery. Some people still use two 100 ah battery but it won't last long as much as a two 200ah.

For me I use four 200ah batteries. The inverter installer interlooped the first two batteries ontop in series, then the second two batteries below in series then paralleled them altogether. That means it charges them two by two. I now still connected it to a super charger ( though it is not really necessary). But I always supercharge it once in a while to maintain the battery from ever going low.

I hope you understand or this make sense to you. Mine last for minimum 10-14 days without NEPA. Cause I don't use it for fridge or Ac or pumping machine. My total load is not even up to 400w or 500w ( few bulbs, laptop, TV, game, air coolant (once a while),phone charger ) that is all.
And most time all my appliances are not on at the same time.

My next plan is to get DC appliances, I heard that is the next way to enjoy electricity if one wants to live an OFFGRID life in Naija.

ojeysky:


Interesting, even if you are discharging at 10A which is about 160w your 400A @24v battery bank won't last 48hrs(which is 2 days) and this assumes 80% DOD which is not even healthy for lead acid. Can you clarify how many hours you run daily before folks start getting motivated on 400a setup that lasts half a month.

Fisher007:


Oga na 800ah battery on a 2.3kva microtek before was 2.5kva mercury and trust me mine last for almost a week to two weeks without light.

Or may because I run it overnight and am out next morning. But there was a time when there was no light for a week or more. I never still had issues

If your batteries doesn't last more that 24-48 hours then you have a bad battery or your inverter dey drain light .

I don't carry much like I specified earlier. Mainly lighting port and socket . My air coolant is not on all the time and my TV nor laptop too.

So you have 8 200Ah batteries ran in 2s4p since your inverter is 24v? Or are you using a 12v inverter? In both scenario unless your load is 50w it won't last (24hrs X 7 days). I think the times you are away (assuming you are not using your inverter during that period) should not be counted. Enjoy!

ewizard1:

4 x 200ah batteries could be 800ah @ 12v , 400ah @ 24v or 200ah @ 48v.

By your 2.5kva inverter, it should be a 24v 400ah. it still not adding up to your stated time.

Fisher007:


Ok I guess the time am away. But still, I run it overnight from 7pm to 7:30 am during the power shortage that lasted for almost a week and had no problem.

Well it works well for me. I still can't believe that an inverter can't last more than 48hrs or 72hrs if well charged .

Fisher007:


Ok mine works fine for me. You should probably charge yours well or change the batteries. Or use a super charger to boost or charge your batteries.

ojeysky:


It's not the inverter but your load. My average load is about 170w from 6pm to 7am and that cost me about 120A of battery bank storage.

Fisher007:


How many batteries and what inverter if I may ask?

JaySterling:
1. Which brand of batteries are you using?

2. Since your inverter has an inbuilt charger, what is the need of connecting an external charger again ?

ojeysky:


200AH Lifepo4 with felicity or MPP GK inverter

Fisher007:


Ok no probs. Ask them if they can supercharge the batteries? You never can tell . Safe

Fisher007:


Brand of batteries - I use four 200ah Genos batteries.

Yes it is true inverters have inbuilt charger, but in most cases, they never charge it well. Most times your batteries go low and to bring it back up with normal inbuilt charger is not attainable.

Haven't you heard of cases where the inverter batteries seller will tell you they need to supercharge your batteries so that it can attain back it optimal use ?

Although most of them will just tell you, your batteries are dead or bad. Lol They probably supercharge it or resell it sha.

And by the way, the supercharger is connected with the inverter and the batteries directly. It is not separate.

How long have you been using your batteries with the "super charge" set-up?

saint2ace:


Can we see a pics of Ur setup especially Ur charger. Thanks

Fisher007:


Ok here it is. Una wan give me work for this convid19 lockdown. It is dusty though. Here is the pic of the super charger, battery and setup. I had to remove the cover and the super charger from the electric port.
If it makes sense to you. I am not the installer though.

Before person go Qoute me as liar LMAO

Fisher007:


Almost 2yrs. It is even dusty. Lol

Okay plan for a replacement in near future unless you've but be discharging below 50%

saint2ace:


Lolz, not to worry I understand the connection. Unfortunately the name of the charger is in Chinese. Thanks for the effort bro, much appreciated

Modified: Ran a quick check on AliExpress using the picture u sent and what I found is a 10A 12v/24v mini charger. Is this what charges Ur battery? And if so how long does it take to charge? Sorry for the plenty questions

Timileyin1234:

ewizard1. U see say this guy too dey use external charger. Abi ur own na UPS ni
