PWM is a waste of money. It's very inefficient. Save your money and get a mppt instead.
You can find 100w panels on Amazon around $65-$70 all day long so this not a good deal.
$40ish for a MPPT is cheap. It's a clone of the BougeRv that a lot people use.
It's actually made by Helios and everyone just put their name on it.

I have a SRNE 20a and a HQST(Helios clone) 40a and they have been rock solid. I bought the 20a a while ago for $55 and the 40a can be had for $110 all the time.

When people say the PWM is only $20, to me that's just $20 wasted. Put that $20 toward a MPPT.
A 20a mppt is good for 3 100w panels in 12v but good for 6 100w panels in 24v.
If you want to future proof your system go for a 40a mppt and go 24v from the start.

It doesn't have to be cheap, I just want to use it
As a research model for reference on what's good and what's not

You will need branch connectors to connect the two panels in parallel:

As the EB3A is current limited to 8.5A it may top out at 150W or so depending on the operating voltage of the panels which is likely a bit less than 20V. It may be a wash anyway as the panels only output 80% or so of their stated wattage.
You don't need the PWM Charge controller as the EB3A already has an MPPT.
Also note that the cheaper smaller solar controllers may not handle the voltage or current of the larger panels, you need to match the panels to whatever you are plugging them into.
