Some things to remember: MPPT is the most efficient way to control youir solar gathering, and will allow
use of less wattage in panels because of its efficiency, which is why my 80w set up works so well.
(quoted from another van nutz post when I was inquiring)
The big difference is this -
Simple on/off controller is roughly 40% efficient
Pulse width might get you 50%
A decent MPPT can get you 90 to 97%
MPPTs do a magic thing - their power in is almost equal to power out but the
volts and amps are fiddled with. So 18 volts (roughly where solar panels are
most efficient) at 12 amps input can be converted to almost 18 amps at 12 volts
charge current (where the battery might want a charge right now). And they
adapt to power delivered and charge needed second by second.
An MPPT at $250 is roughly equal to about the cost of a good 90 or 120 watt
panel and can save you that much or a lot more in solar panel money spent.
I currently use a Solar Boost 2000e which will handle 25 amps and is 94 to 97%
efficient for my system. It also will equalize the battery system, has
temperature compensation and can be set for optimum base battery voltage.
And on amps, make sure when you size an MPPT controller you pay attention to
whether it's X amps in or X amps out. I bought a cheap one ($100) for my 180
watts of panels and neglected to pay attention to that. It was 10 amps in but
ended up almost 15 out which burned up the 10 amp out MPPT controller.
I can't say too many good things about Solar Boost products. They are great.
