JeroenH;

I have been looking in on your diary lately and I am curious how you are figuring SOC? From voltage, specific gravity or what?

Thanks.

Hi!

Thank you for your interest. As you can see here:

I have a very nice charge controller which displays the SoC in a percentage value. As I have gel batteries there is no way I can measure the acid density. I don't know yet how to judge SoC from the battery voltage, as it seems to fluctuate depending on the load that is connected to the batteries.
