Error Codes
If the Rover is not functioning correctly, it may be undergoing an
internal electronic protection and sharing an error message.
The error messages stop normal operation and clear when
resolved. This is not indicative of a defective controller but may
require some troubleshooting to resume normal operation.
System behaving normally, no action
needed. You will not see this error code.
Use a multi-meter to get a reading of the
battery voltage in volts DC to validate
error code. Battery is very low.
Disconnect any loads to the battery and
let the solar system charge the battery
backup. If the battery voltage is low it
may be in open battery protection mode,
which is a Wanderer Protection.
Use a multi-meter to get a reading of the
battery voltage in volts DC to validate
error code. Battery is charging very high
and approached 16VDC. Disconnect any
external chargers and isolate which
charger is overcharging battery. Eliminate
from system.
The load terminals have made contact or
there is an internal short affecting the
circuitry. Disconnect any loads and use a
multi-meter to measure the voltage to at
the load terminal to make sure it matches
the battery voltage. Double check the
load mode. Disconnect the controller from
the battery and restart.
