What a concept, a simple controller to integrate with his proven Trimetric and make a great argument that 95 percent of people buy MTTP because they are told to or think they need it? After all, why would anybody in their right mind design such a system and not include MTTP? ;)
Without any details about that concept it's difficult to comment.
One thing I know is that any controller can be used with a battery monitor. Not to say that every system needs a battery monitor.
As to why they didn't make this device an MPPT, there can be one good reason - cost.
I can believe that many people decide on a controller type and brand without fully understanding these things. Though in systems over 30A - and there is more and more of them lately - an MPPT is usually the only way, or the most efficient way. Which is not really relevant to this 30A PWM. Or to the OP topic - I sense RJ picking up stones already. Though I'm myself not quire sure what this topic was about, from the beginning :)
