MPPT Solar Charger Error Codes
Solar Chargers indicate an error with their LEDs. See the Toolkit App for the LED codes.
Detailed error codes can be read with a remote panel, such as the Color Control GX or the MPPT
Control.

Error Codes

Err 2 - Battery voltage too high
This error will auto-reset after the battery voltage has dropped. This error can be due to other
charging equipment connected to the battery or a fault in the charge controller. This error can also
occur if the battery voltage (12, 24 48V) is set to a lower voltage than the connected battery.
Err 3, Err 4 - Remote temperature sensor failure
Check if the T-sense connector is properly connected to a remote temperature sensor. Most likely
cause: the remote T-sense connector is connected to the BAT+ or BAT- terminal. This error will auto-
reset after proper connection.
Err 5 - Remote temperature sensor failure (connection lost)
Check if the T-sense connector is properly connected to a remote temperature sensor. This error will
not auto-reset.
Err 6, Err 7 - Remote battery voltage sense failure
Check if the V-sense connector is properly connected to the battery terminals. Most likely cause: the
remote V-sense connector is connected in reverse polarity to the BAT+ or BAT- terminals.
Err 8 - Remote battery voltage sense failure (connection lost)
Check if the V-sense connector is properly connected to the battery terminals.
Err 17 - Controller overheated despite reduced output current
This error will auto-reset after charger has cooled down. Check the ambient temperature and check
for obstructions near the heatsink.
