Give me your opinion - CTEK D250S vs MPP Solar PCM-3012 (1 Viewer)

[Sidney]

I'm at sixes and sevens.

On the roof lets say I have 300w of solar (2x150w)

I could feed the solar into the Ctek D250s Dual and benefit from the box doing all the work.

• Charging the leisure batteries
  
• Pulse charging the starter battery
• making the most of the 20 amp MPPT facility built into the dual

Because there is no display on the Ctek unit I would also use a sophisticated battery meter with shunt so I'd know what was going on charge/discharge etc

Or

Still use the Ctek dual for DC-to-DC and simply wire the solar into the 25 amp MPP Solar unit and get a better idea of what is happening with solar panels and either put in a switch to enable me to switch over to the starter battery manually or buy a sterling battery maintainer to do the job automatically.

I think I know the answer. In which case I may have a unused and boxed MPP Solar PCM-3012 controller for sale

LOL You asked and answered your own question. Throw a dice......or two.

I guess the unknown element (for me) is how good the MPPT facility is on the CTEK unit. I can't find any teardown or proper reviews on a workbench - just Aussie's saying how "its just rippa".

Perhaps for the benefit of other Funsters I'll set up some tests with both units.
