Got my solar project finished.

I guess I don't understand what the controller is saying. Voltage is obvious, amp hours is probably for the day or maybe total since reset, but I don't know what total amps could be as amps are an instantaneous reading, not a total of anything. Are you sure you don't have total amp hours and daily amp hours? Or maybe amps to go with the volts?

I probably am confusing my terms - it's been avery long day.

This is the controller I have - http://zampsolar.com/newsite/wp-cont...web-upload.pdf


It gives voltage, charging current and charging capacity (ah). The current was reading 14.5. The capacity had a pretty high value as it was around mid-day, but I don't recall what it said.

But looking for the link above, I see they now have a lithium specific charger, so I'm probably going to go ahead and order that.
