The Question by a customer “can this be used with a solar charger” was not given a good answer. The answer is “YES” it can be used for that purpose...PROVIDED the AN2552/MS3506 is directly connected to the battery and not thru a relay. (See your aircraft wiring schematic. An example is the Cessna 170B Illustrated Parts Catalog, in which the AN2552/MS3506 is directly connected to the battery-side of the master switch relay at the battery box. ) This is how mine is installed and I keep it continuously served by a battery maintainer this way. Hope this helps.
