The panels are connected to the controller but not
charging or not detected.
1.Use a multi-meter to verify a PV voltage as well as
the voltage being within 15 – 40VDC
2.Use a multi-meter to verify the correct positive and
negative polarity matches the polarity seen on the
OUTPUT port.

In non-lithium setups or setups where the Lithium
battery is fine, the Rover Boost’s rated PV watts have
been exceeded and it is therefore current limiting.
1.Double Flashing will continue until the Controller
has exited MPPT/Bulk stage. Afterwards, it will
continue through the normal charge state LEDs.
There is no issue, and this is a protected function of
the Rover Boost if the PV watts stay within the
designated values:
Exceeding the Protection Mode Limits may
result in irreversible damage and not
covered by warranty.

OFF
The panels voltage is higher than the controller’s
maximum input.
1.Use a multi-meter to verify a PV voltage as well as
the voltage being within 15 – 40 VDC.
2.Check your solar panel input against your battery
system voltage. Use a multi-meter to check that the
incoming voltage is within 15 ~ 40VDC for 48V
systems. If this is a 36V system, the PV voltage
should not exceed 15 ~ 25VDC.

If you are using a Lithium battery, it may have
undergone over-discharged protection and the Rover
Boost is attempting to wake-up the battery. Refer to
Lithium Activation in the MPPT Technology Section
for more information.
1.
Use a multi-meter to measure your battery voltage
and determine whether it has undergone a protection
mode. Disconnect any loads and let the Rover Boost
charge and wake the Lithium battery.
