Fault Indication
Fault 1 – Low battery voltage.
The SunExplorer III display has advanced to the battery
voltage location and blinks both LED and display reading. This occurs when the battery voltage
has dropped to 11.8VDC, a level that could start to damage your batteries. This generally occurs
at night when the SunExplorer III cannot charge the batteries. Recommend turning off all loads,
plug into shore power or use a generator to charge the batteries.
Fault 2 – Battery high temperature.
The SunExplorer III display advances to battery
temperature location and blinks both LED and battery temperature and the SunExplorer III backs
off the charging current to prevent further heating of the batteries. Once the battery temperature
drops below 125 degrees F, the SunExplorer III will regulate the charge to keep the battery(s)
temperature from increasing. Once the temperature has dropped enough to resume normal
PWM charge rate the display will stop flashing.
Cleaning Tips & Warnings
Do not spray water or cleaning solution directly on the face plate or LCD of the SunExplorer III-35.
The liquid could run between the face plate and the LCD on to the circuitry of the SunExplorer III-
35 circuit board causing damage to the electronics and WILL VOID THE WARRANTY!
Recommendation for cleaning SunExplorer III: Apply water or cleaning solution to a soft cloth and
spot clean the face plate as needed.
