PV will not display
or charge
PV Reverse Polarity
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.
PV Over-Voltage
The panel’s 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.
Charging current is
lower than
expected; PV
current may also
be low
Float mode
The controller is normally operating in a Float mode,
where the current is reduced to control and maintain
the battery.
Shaded Panels
Inspect the solar panels for any dust or debris on the
surface. Clear anything creating shade to resume
normal operation
Low Insolation
Atmospheric conditions such as low clouds, haze, sun
setting will reduce the panel output as the insolation
conditions also drop attributing the lower power
output. Clearer conditions will increase performance.
High Temperature
While not outside of operating conditions, higher
temperature reduce the efficiency of the solar panels
with excess heat, where the maximum power voltage is
not much higher than the battery voltage, leaving little
to Boost.
Improper Wiring
The panels are experiencing higher voltage drop due to
undersized wiring, poor connections, or perhaps higher
environmental conditions. Double check and secure all
connections and verify correct gauges.
Rover Boost was
Charging but then
stopped
High ambient temperature
High temperature or residual temperature may prevent
the controller from resuming charge. Ventilate the
charge controller location or reduce PV power to lower
heat.
Rover Boost not
charging properly
Incorrect Battery Type
If you have a 48V Battery, make sure to press the SET
button to toggle the controller to a 48V battery system.
