Greetings again,

Opinions on choice of MPPT products is solicited. The prices of controllers is down from past years. Are there any opinions or comments about this one: <https://www.amazon.com/gp/product/B071X ... AJEM&psc=1> ? Seems fairly capable for a middle cost one. Other suggestions?

I consider replacing a bad PWM controller with it. I'm initially charging two Vmaxtanks AGM 125 AH batteries with two 100 watt 12 volt panels. There seems to be room to add two more panels in the future,

Thanks friends, Roly

Roly,
My choice for a 200W plus system:
Morningstar PS-MPPT-25 ProStar MPPT 25A Solar Charge Controller

With 4 panels, it will be 400W, and it will probably need a 40A controller. Does the Morningstar have a similar controller that can handle 40A?

Yes. With or without a display:
