Troubleshooting
If the LED indicator does not light with a battery connected, or blinks the over-battery-
voltage error, or the controller does not charge, the fuse may be blown. The GVB-WP fuse
is located in a black waterproof in-line fuse holder in the positive battery line. If the fuse is
blown, replace it with a 10A fast-acting ATO or ATC fuse rated for at least 58V. Automotive
fuses are typically rated to 32V, and are not acceptable. We recommend Littelfuse part
number 142.6185.5102, rated to 58V.
The most common causes of blown fuses are:
• Connecting the GVB-WP to the battery backwards
• Shorting the solar panel input while the GVB-WP
is charging. In this case, there may be other internal
damage to the controller.
