The MPPT charge controller matches the changing voltages caused by the state of charge of the battery and can result in 30% more efficient transfer of powerReduce the number of solar panels needed by up to 30% - a tremendous benefit and leverage the rest of your system to better performanceFull power output in ambient temperature up to 45 DegreeC, nature convection cooling, temperature compensation4-Stage charge with PWM output, quick tracking speed. Can be used for sealed, gel, and flooded batteryNegative grounding, peak conversion efficiency of 97%, and high Tracking efficiency of 99%

I am also a solar panel noob but i just managed to set up a system in my bus. I went with 4 renogy panels, they're cheap, good, and seem to have a good customer service.

We have 3 of them for 2 people. You will need a charge controller to regulate the energy going to the battery. If you opt for a nicer MPPT controller, you will have 30% more nergy coming to the battery. That's what we did.

For more of an idea on what to do for the electrical system, i used a video by a guy named campervan cory.

If you have any more questions, feel free to ask.
Hmm...so basically overcharging it a little helps a lot? Though the best method would be to just keep it fully charged all the time. I've seen it hit >28v before on the batteries so I think I should be good with equalising.
They are indeed 60 cell and have a Voc of 39.6v@25C at it's rated power. They're connected in series. This is mainly to minimise voltage drop and lower the amperage along the wires.
I do.

As well as the inverter that I'm planning to upgrade to: http://www.magnum-dimensions.com/product-inverter/4000w-24vdc-pure-sine-hybrid-inverter-charger-msh-series
And the panels: https://www.solarworld-usa.com/~/media/www/files/datasheets/archive/sunmodule-bisun-duo-solar-panel-datasheet.pdf
here is what i have going on.
2 100 watt mono solar panels connected parallel via mc4 connectors.
they connect to the tracer 20amp charge controller, think its 8awg wire here.
then i need to connect the charge controller to the battery. the battery is a 12v deep cycle interstate 94 aH. i wanted more juice, so i parallel connected a 12v 34aH golf cart battery to it.
my question is what gauge wire and what fuse i need on the + wire from the charge controller to the battery?
the panels wil grab not more than 15aH.
