Battery Capacity (AH) setting for TRIRON 3210N

[Lupin500]

Please excuse me if this a really stupid question but I am a bit confused about the Battery Capacity setting for my TRIRON 3210. Should I input the rated Ah of a single battery (220Ah in my case) or should I add each one them (I have 6 of them, each at 6V connected in series to get 12V). If it's the combined amount, is it 220Ah x 6 = 1320?

Thank you for the help!

Not stupid. Common mistake. Have to learn:

Series = add voltage, capacity stays the same, current flow for a given power decreases (24V requires 1/2 the current as 12V for a given power)
Parallel = add capacity, voltage stays the same, current flow is the same, but it's divided amongst the series batteries.

You have both.

The assembly of your cells/batteries is your battery bank. It behaves as one giant battery. You should input the total bank capacity for that voltage.

You appear to have a 2S3P configuration, so the series don't add, but the parallel do.

You have a 660Ah 12V battery.

Another way is to convert to kWh:

6 * 6V * 220Ah = 7920Wh

Then you divide that number by the voltage:

7920Wh/12V = 660Ah

for your Ah capacity.

Thank you so much for the detailed answer snoobler, this really helped me understanding.

That should be parallel.
