That’s terrible efficiency! Thank you for posting.
85% is typical for converters and chargers so not "terrible" at all.
Plus the "efficiency" of a solar controller varies with how much buck or boost it is doing, so I am guessing it is the same with the DC-DC units of whatever brand. Although solar controllers are in the 90s % not the 80s like converters.
