I have a 310W household solar panel. I don’t have the exact specs or data sheet for the panel. Assume it’s around 36v and max output of 9A. I have this panel connected to a Renogy 20A MPPT charge controller charging a 12v 280AH AGM battery.
In full sunlight during the middle of the day the max output of the charge controller is 20A.
The battery is often drawn down to 12.1v so I seem to use most of the available capacity. Now I assume that if I had a larger capacity solar charge controller I assume that the panel would be able to output more than the 20A that I currently get.
Just wanted to confirm here how much power I’m probably missing out on here. I assume that I’m probably missing out on the 5-7A for 1-2 hours around midday. Is that about right?
