D-Sun Power supply max involt voltage

Inquiring minds have asked, "What's the maximum input voltage on the D-Sun converter?
My solar array charges at 14.7vdc. I'm sure that's within limits, but I really don't know."
This is the power supply that is used on the Hive Interface board versions 0.1 - 0.3.

Supposedly, input voltage is 28 volts max. Also note that 3A out is a maximum and not a continuous rating.

Specs from a vendor on eBay:

Input voltage: 4.5-28V
Output Voltage: 0.8-20V (adjustable)
Output current: rated current 3A(MAX).
Switching Frequency: 1MHz
Output Ripple:less than 30mV
Operating temperature: Industrial grade (-40 C to +85 C)
Module Properties: Non-isolated step-down module (buck)
