Go MPPT..
Get a renogy rover... good for 100 volts solar.

Are you panels all the same?
If so youll have up to 68 volts to controller. volts above 14,7 get converted to amps.
You will start charging way earlier in the morning because you have higher voltage. 4 panels at crack of dawn will be well over 14 volts. Enough to start charging..
No need to upgrade wiring..
Its the best and cheapest option out there IMO. 160 bucks gets you temp sensor and computer interface to change voltages to your batterys charging specs..
I have one 280 watt panel @ 38 volts with a ecoworthy 20 amp mppt and I get close to 20 amps all day..
5pm today late sun I was getting 12 amps. PWM calc I would of only been getting 8 amps. 53% more efficient with mppt.....
