Reduce the utility charging mode to 20a or 25a, leave the solar charging current as it is as that will be determined by the number of solar panels you connected to it

Mercury batteries are good, all the attached jobs were done 2021/2022 and to my surprise, they are still working

feflo:
Adequately enough sir

As someone that has used, supplied and worked on almost all battery chemistries, I will advise that you look into going for LITHIUM, if of course money is not an issue.

Now back to your question, I will assume it's a solar system because the inverter is hybrid and that it's a 2.5kva 24v inverter.
24vdc 220ah flooded Vs. 24v 300ah SMF

The flooded has a total of 5.2kwh storage with 2.6kwh usable (50% DOD) while the SMF has a total of 7 2kwh with 3.6kwh usable.
Flooded is more durable and can take or withstand large charging amps while large charging amps can damage SMF chemistry.

4pcs 150ah batteries requires more installation cables and increased point of failure than 2pcs 220ah batteries, it's also easier to upgrade to 48v system by adding to more batteries and get more watthrs than converting the 4pcs 150ah to 48v and get less watthrs or be forced to add four more batteries - more expenslve.

Flooded requires periodic maintenance, the electrolyte is acidic and can damage stuffs if it spills, it's also not advised to be used in a room with little or no ventilation, outdoor use is best while SMF requires no maintenance and can be used indoors.

Personally, if those are your options, I will advise 2pcs 220ah batteries

Thanks.

NB: If cost is your only consideration when buying batteries, I'm afraid you will not get premium battery and might spend more on the long run

Dam5reey1:
Yes it does,
The 1.5KW 12V Hybrid. 343k.. version

Dam5reey1:
They are not that expensive.. if you check the life span.. but come with some careful practice too..

You can get 2.5KWH (12V 200AH or 24V 100AH ) for ~ 600K..
90% usable capacity..
But you must get an inverter with editable battery profile, where you can set Battery cutoff and Bulk voltage. Ranges from 400k.. for Mercury hybrid

fashrola:
Do you have the model name?

mctfopt:
Do 24v

Obnoxious2001:
24v is your guy then

dollarnaira:
The advice had been given before. Go for LifePO4 bro as you don't need pampering.
Lead acid should not be granted such amount of money. Spend wisely.

Dam5reey1:
Get 12V 1.5kva..
Parallel your 12V Lead acid batteries.
Better Idle Consumption..
Your continuous loads are under 300w

24V will force you to series and will eventually cause some issues in long run..
You will loss power to self consumption..

Your Next Future upgrade should be 48V or 24V.. 3.5kw and LFP batteries..

fashrola:
I need 12V 1500watts Pure Sine Wave Hybrid Inverter with 80A Inbuilt MPPT Charger

I've only seen PowMr brand with this spec, but any recommendation for a good and more affordable brand that is compatible for Lithium or LA Batteries is highly needed

If you are a vendor, Kindly quote with your price.........

dollarnaira:
I keep shaking my head upon your decision.
580k bros as in 580k for this period ooo.

Obnoxious2001:
In actual sense, the 150ah is a better option considering that battery life span will be higher.
however, there is an overhead cost in getting solar panels/means to charge them effectively.

isangjohnson:
Your analysis may be wrong. 2 pcs of 220ah will give you 2.64kwh dod and 4 pcs will give you 3.6kwh dod.
Choosing between 24v system and 48v system will depend on your loads and your budget.

Obnoxious2001:
Both

dollarnaira:
Biko how much is the tubular?
I really wish you research to confirm the continuous power of the inverter if it is truly 750w. Mind you, your freezer will do btw 600 and 960w surge.

Obnoxious2001:
Do you have the picture?
