Battery Charging Time Computation

[Ferdinand Perillo]

Good Day,

I am having trouble to compute the charging time of my battery with this kind of set-up:

(2) 300W 36V PV Panel
(1) 500W 24V Wind Turbine
(1) Hybrid Charge Controller
(6) 12V 200Ah Batteries @ 24V Configuration

The batteries are connected to series-parallel connection that will give 24V 600Ah output.


How long is the charging time of my battery?

Thanks in advance!

1. find the charge current in amps.

2. Divide 600 by the number found in (1).

3. Multiply the number from (2) by 1.5.

the number you have is the charge time from dead flat in hours.

if you need to know what it is from x% charge, multiply it by (100-x)/100.

Hi,
can I ask where did you get the 1.5?


thanks

you need to put more energy back into a battery to charge it than you got while discharging it. 1.5 is just a rough estimate.
