Our high school team entered a solar powered boat in the Sacramento Municipal Utility District's (SMUD) Solar Regatta Friday, May 3rd. Two 230W solar panels powered a 24V brushed DC motor to drive the 15 foot piloted, wooden boat. We used an EP Ever 30A solar charge controller. After a few minutes on full power the solar charge controller shut the motor down and displayed an "overload, Load short circuit" error. The EP Ever manual said it would go out if the load current exceeded 100%. The manual also said the power would be restored. The time to restoration was based on the size of the overload.
How does the solar charge controller know the rated amperage of the motor? Is it based on the battery data we input into the solar charge controller? We used two 12V, 7A batteries. Contest rules limited the battery pack to 180W. Would the overload error go away if I set the amps to the amp rating of the motor (350W/24V=15.5A)?
Thanks in advance for any clues to our problem.
