I am planing on powering my HL2 from a solar panel and battery.  It occurs to me that there are failure modes that could have the HL2 seeing the full open circuit voltage of the panel (around 22 volts).  How high a voltage, for how much time, can the HL2 handle without damage?

thanks,

Hi Steve,

The HL2 is rated for max input voltage of 18V. This is based on the datasheet for the switching regulators:
