Pairing up the Eco-worthy 20a MPPT controller
Thanks to BFL confirming that the Eco-Worthy controller plays well when run with another controller, I felt pretty good about combining my two matched controllers. Each had one of the Bosch 245w mono ...

Why do ya need a DC to DC if no MPPT?
For those that use nominal 24-volt panels it is imperative unless you want to lose half the power.
I thought MPPT fooled the panel to put out more power than the battery load voltage so that if MPPT is off, the panel would only put out battery voltage (walk the power curve as batt volts rise).
No. It decouples the panel voltage from battery voltage so the panel can operate at the voltage that produces the most power. No trickery required.
If MPPT is off is there other logic to fool the panel to put out more volts (power) than battery volts?
