Troubleshooting
If the LED Indicator will not light, or displays an indication not listed in this manual:
•
Verify correct battery polarity.
•
Check that there is a solid electrical connection to the battery.
•
Check that battery voltage appears on the GV-10 battery terminal screw.
•
Check the GV-10 terminal area for water or mechanical damage.
The GV-10 will not operate without a battery. If the system appears to be overcharging or the GV-10 will not begin charging, ensure that the solar panel is wired only
to the GV-10. If the GV-10 does not appear to be charging, note that the GV-10 waits up to one minute before trying to restart if is has shut down due to lack of power
from the solar panel. If the LED indicator will not light with a battery connected, or blinks the over-battery-voltage error, or the controller does not charge, the internal
fuse may be blown. Check the fuse inside the GV-10 by removing the four screws on the bottom of the enclosure. If the fuse is blown, replace it with a 20A fast-acting
ATO or ATC fuse rated 32V or higher. For more in-depth system troubleshooting, please visit the support area of our website: https://sunforgellc.com/learning-center/

(2) Panel Isc. Max input power and maximum input voltage requirements must also be respected.
(3) Max current that the controller could draw from an unlimited source. This specification is not intended for determining PV input.
(4) Max ambient temperature for full operating current.
Note:
The most common causes of blown fuses are:
• Connecting the GV-10 to the battery backwards;
• Shorting the solar panel input while the GV-10 is charging;
• Disconnecting the vehicle's battery while an alternator is running;
• Connecting the GV-10 battery terminals to a 24V battery.
In the latter three cases, there may be other internal damage to the controller.
