What is your battery Voltage?
If 12V then you are getting 200W maximum from your panels.
If 24V then you are getting 400W maximum from your panels.
In each case you will not be getting near the 790W that your panels could make.

For 12V battery you would need a 60A charge controller.
For 24V battery you could use a 30A charge controller.

Panels are probably over the limit for winter, unless wired in parallel.
