Mecer 720watt can do 10a and 20a charging.Is the 10A recommendation for 2 batteries or for 1?
What amp does the 700W Mecer charge 1 battery at I wonder

now that you only have one battery, you should double it's size to compensate because you're coming from 2 batteries to make 24V.But if im correct due to 12v now and not 24v, the equation shows that less hours are gained on the battery?
Example: side note, i suck at math
12x180ah(one 12v batt)/wattage 650/2 x0.85=1.412
24x180/650/2x0.85=2.824
for 1 battery i think.Is the 10A recommendation for 2 batteries or for 1?

because of 2 batteries vs 1 battery.Yes, you have more energy on the 24V system than the 12V.
all i'm saying is lead acid likes low and slow charging. i guess if you have 4 batteries hooked up then 20A is fine.Mecer 720watt can do 10a and 20a charging.
20A is way less than what 2 x 105ah can handle. Go for it. Why suffer needlessly.Yeah its mainly as in PE we have 12 hours on average for stage 3 and then there is not enough time between to charge, so ill give 20A a try, maybe only if its stage 3
Edit: just to clarify I have 2x 105 Ah batteries
I assume you are looking at 12V batteries.But if im correct due to 12v now and not 24v, the equation shows that less hours are gained on the battery?
Example: side note, i suck at math

24x180/650/2x0.85=2.824
I've posted this before, but use this to do your own calculationsSo my new updated question is
What are my battery needs on a 12v inverter to run 2-3hours at 650watt
If he uses two batteries in the 12V system.I assume you are looking at 12V batteries.
So for a 24V system you need 2 x 12V batteries
In series the voltage is doubled, the capacity stays the same so 2x12V180Ah =2x12Vx180Ah/2x.85/650 = 2.8Hr
In parallel the voltage stays the same and the capacity doubles so 2x12V180AH = 12Vx2x180Ah/2x.85/650 = 2.8Hr
you have this completely wrongnow that you only have one battery, you should double it's size to compensate because you're coming from 2 batteries to make 24V.
you were getting 2 x 150ah, now only 1 x 180ah, you should be getting 1 x 300ah battery to get the same use out of 12v.
24V x 150ah (2x12V150ah)=3600 watt hours (remember, parallel batteries, voltage doubles, current stays the same)
12V x 150ah (1x12V150ah)=1800 watt hours (here you would do series (if you can't find a big enough battery) and add batteries which keeps the volts the same but doubles current)
one thing to note going 12V is more current where:
700W @ 24V = 700 divide 24 = 29.16666666666667 amps from your battery.
now 700W @ 12V = 700 divide 12 = 58.33333333333333 amps from your battery.
so you can see there is more load on the battery which will shorten the amp hour rating:
"A 1C rate means that the discharge current will discharge the entire battery in 1 hour. For a battery with a capacity of 100 Amp-hrs, this equates to a discharge current of 100 Amps. A 5C rate for this battery would be 500 Amps, and a C/2 rate would be 50 Amps. Similarly, an E-rate describes the discharge power. "
Think you'll need at least a 300ah battery @ 12V and thicker battery cables and bigger fuse.
Its on back order, so not worth it anyway. All the stock comes from mustek, but seems pclinkshop is getting first dibs on the stock.Is this site legit?

If he wants to get through load shedding using 600W/Hr he will need 2 150AH 12V batteries on both a 12V and 24V system.If he uses two batteries in the 12V system.
Nifty little excel. ThanksI've posted this before, but use this to do your own calculations
Is it safe for work?I've posted this before, but use this to do your own calculations
Either way it seems yea, or one big ass battery like a 300ahIf he wants to get through load shedding using 600W/Hr he will need 2 150AH 12V batteries on both a 12V and 24V system.
Don't put all you eggs in one basket.Either way it seems yea, or one big ass battery like a 300ah
good point,Don't put all you eggs in one basket.
