so on luminous india site, they stated that the 220ah 12v flooded batt will last about 4hrs on 500w load , and 29hrs on 100watt load.
am a lil confused, assume I connect the following, which will last longer?

A. 2x 12v 220ah batt to a 1.5kva 24v inverter to power a 500w load

B. 1 X 12v 220ah batt to a 1.5kva 24v inverter to power a 500w load.


Can you correct B above ( 1 x12 V ) cannot be connected to 24 V inverter .

In general any Lead Acid battery ( wet , AGM, GEl) likes to be used on C10 or C5 rate based on design . Any higher current drawn above C10 will result in reducing teh overall AH ( energy delivery) of the battery .

So a 220 Ah battery will be able to deliver 220 AH ( 220*12V-2640 watt) if the load is 22 Amps ( 12 V x 22 amps- 264 Watts) for 10 Hours
Same battery at Higher load will likely drop to 170 AH

Also Keep in Mind the battery should be used only upto 50 % DOD in Home solar applications which means a 12 V 220Ah battery system should be considered In design to support a load of 264 watts only for 5 hours

So technically it better to discharge 50% than 30% of battery capacity

@30% I will only get 165,000AH from my battery.. whereas
@50% I will get 175,000AH.

Abeg what's​ the logic here?

No! Technically it's better @30% you get longer battery life than @50%

The logic is that @ 30% you can charge and discharge it 2750 times while @ 50% you can charge and discharge it 1750 times.

That means that while discharging it to 30% the battery lasts longer than when you discharge it to 50%.

Thank you. More power less life span, less power taken out of the batteries more life span. Hope this is logical?

What he meant is overall at 50%, you draw out more returns on investment that at 30%. He is a very good economist however sometimes availability outweighs cost! For instance d 30% discharge plan gives more longevity before replenishment as opposed to more 'harvest' from d system.

Batteries are the most expensive part of the system.
I need a battery @90% DoD and 15000 cycles! grin

I'll admit he does his homework quite well. When in doubt, he'll call people with real life application and experience to hear their views and inferences. He's good at what he does. And that's how things should be.

That's why RE is no joke. Takes lots of planning and serious consideration. Money doesn't always come easy but time is about the most expensive currency we humans deal in. You have to do a delicate balancing act between your needs and desires. My own recommendation: if you want more time out of your batteries, size them appropriately or get the right chemistry type.

I learnt a few years ago to always copy my replies before posting them. Nasty surprises occur more frequently than one would expect (my first post today required 4 attempts to get it through). And it seems the site has a grudge with the Glo network.

Re: Solar Energy, A Complement To FTA by BasedOnB: 1:34pm On Jun 21
Hello everyone, i need some quick advice here please.

I have a 800 VA sukam inverter, a 250 W panel, and a 30 amps PWM controller. My current 150 AH battery is long due for replacement, so i am thinking of replacing it with a new 200 AH. My concern is that the panel may take too long to charge the battery full, even though i don't intend to discharge it to more than 50%. Am i just better off with a smaller battery, say a 150 AH or 100 AH?

I also need recommendations on reliable battery brands to buy (preferably from experience), i kinda believe the so called 'telecom' batteries are solid, even if they are more expensive.

Explained nicely here - http://bobby.com.ng/2017/06/21/battery-discharging-less-can-be-more/

In general 24 V system will be more efficient and run longer

From experience panel array only produce 3 to 4 times it's capacity..

So your 250W will provide about 800Wh.. thats about 60AH of charge.. if you upgrade by 50AH how do you charge it?

If your 150AH is serving well with the panel.. then stick with it.. since 30A PWM cannot accept a perfect additional​ panel..

Thanks. Load is about 120 W max, most times it's just about 80 W.

The 150 AH battery is virtually dead, i have to change it. So the 30 amps controller can't charge a 200 AH battery? Thanks for the input.

It can, simply​ add another panel..

I mean you should buy another 150AH battery if your panel charges it effectively..
