Tips: Maintenance and clean of ATO MPPT solar charge controller

1. Replacing the fuse

Due to the high temperature or other failures resulting in the broken fuse, it needs to correctly replace the fuse of the solar charge controller. It should first remove the broken fuse from the terminal box, and install a new fuse. Then check whether the connection is correct or not. Finally install the equipment. (The fuse is near the terminal box.)

2. Clean the vent heat sink

Regularly clean the fan vents and internal heat sinks, and wipe with dry or damp cloth.
Note: Do not use detergent or corrosive solvent to clean. No liquids flowing into the machine. Please ensure that the ventilation holes of the charge controller are not blocked.
