I've got a 24/3000/70. My charger is set to draw 15amps from the wall outlet. It's a 20amp circuit. I swear I used to see over 1000watts coming in on "AC IN 1" but now I'm only seeing about 600. It goes up and down if I increase or decrease the charge current, but shouldn't I be getting more wattage from 15amps while charging??
I am using Lithium batteries, I disabled "weak ac input"
EDIT: The charge rate only increases when the load increases. What's up with that?
