Before installation, check to make sure the power is working
properly. Resolve any issues before installation of monitoring
screen and cable.
The following are recommendations for installation. There will be
multiple mounting methods depending on users’ applications.
Please choose a clean, dry, protected and easily accessible
indoor location to install the monitoring screen. It is
recommended to mount the monitoring screen at eye level for
easy access to the battery information and operation buttons.
The RJ45 Communication Port on the monitoring screen is
accessible from the back of the unit. Clearance of at least 2
inches (50 mm) behind the unit is recommended to allow for the
bending radius of the RJ45 Communication Cable that connects
to the monitoring screen.
The RMS-RVRE requires a flush mount installation. The
RMS-RVRE’s faceplate will be flush with the mounting surface
and the body of the meter.
Before the installation of the monitoring screen, it is recommended
to have the following tools available:
CAUTION
Installation
BEFORE drilling, make sure there are no electrical component
or other obstacles that may interfere with installation on the
other side of the mounting surface.

Lithium Battery Activation
Manual programming of 12V or 24V batteries
is only available for Li batteries. For other
battery types, the RMS-RVRE will recognize the
Rover’s Elite’s auto recognition system voltage
and adjust accordingly.
The Rover Elite MPPT charge controller has a reactivation
feature to awaken a sleeping lithium battery. The protection
circuit of lithium battery will typically turn the battery off and
make it unusable if over-discharged. This can happen when
storing a lithium battery pack in a discharged state for any
length of time as self-discharge would gradually deplete the
remaining charge. Without the wake-up feature to reactivate
and recharge batteries, these batteries would become
unserviceable and the packs would be discarded. The Rover
Elite will apply a small charge current to activate the protection
circuit and if a correct cell voltage can be reached, it starts a
normal charge. Lithium Battery Activation.
NOTE
Set Li Boost Voltage:
By default, the boost voltage will be 14.4V for Li. Once in the
Boost Voltage screen, you can navigate in increments of 0.2V
to set your appropriate boost voltage. Press the UP/DOWN
arrows to change the boost voltage. You may select values
between 12.6V ~ 16.0V.
To confirm your selection, Press and Hold the right key to

Troubleshooting
If the Rover Elite is not functioning properly, it will display an
error code not normally seen in the interface display.
Depending on the code, you may attempt to troubleshoot the
error to commence normal system operation.
Error Codes / Troubleshooting
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 Rover Elite Protection.
Make sure controller is in ventilated area
and that the appropriate wire sizes are
used to connect to and from the
controller. This may be creating heating
issues inside the controller. The
controller will resume normal operation
upon cooling down.
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.

Record the ambient temperature found in
the controller screen. Make sure the
controller is not placed in direct line of
heating sources or that it is over-heating
due to over-sun exposure. The controller
will resume normal operation upon
cooling down.
The controller has a maximum dc voltage
input of 100DC. If connecting your panels
in series, make sure the reading does not
go over this limit. Check with a multi-meter
before connecting to the controller to
ensure you’re within this specification. This
might require using less panels.
The battery cables are reversed. Use a
multi-meter to make sure your voltage
reading has the correct polarity (Red to
positive and Black to negative) with a
positive number in volts DC. If the number
is negative, switch the positive and
negative battery cables in the battery
terminal of the Rover Elite.
The solar panel wires are connected in
reverse polarity. Verify using a
multi-meter to make sure your voltage
reading has the correct polarity with a
positive number in volts DC.

Protection Behaviors / Fixes
If the Rover Elite is not functioning properly and is not displaying
an error code, it may be undergoing an automatic protection
function. This does not mean your Rover Elite is defective, but it
requires some troubleshooting to commence normal system
operation.
21
Behavior Protective Function / Fixes
Reverse Battery Polarity Protection
The Rover Elite needs a correct battery
connection to startup. This might mean that
the battery cables are reversed. Use a
multi-meter to make sure your voltage reading
has the correct polarity (Red to positive and
Black to negative) with a positive number in
volts DC. If the number is negative, switch the
positive and negative battery cables in the
battery terminal of the Rover Elite.
The solar panel wires are connected in
reverse polarity. Verify using a multi-meter to
make sure your voltage reading has the
correct polarity with a positive number in volts
DC. In some cases, with the battery and solar
panels both connected in reverse polarity, the
controller will not turn on, but the controller is
not damaged. Simply correct the reverse
polarity to continue normal operation.
The controller has a maximum dc voltage
input of 100DC. If connecting your panels in
series, make sure the reading does not go
over this limit. Check with a multi-meter before
connecting to the controller to ensure you’re
within this specification. This might require
using less panels to make sure you are within
the Rover Elite specified input.

If the battery was charging fine and stopped,
it could be because it was being overcharged
by the solar source if not an external source.
You might see an E02 display or perhaps an
empty screen. Make sure your charging
sources are not charging at 16VDC or check
to see if your batteries are being equalized,
an intentional over-charging, that might be
triggering this error.
The max amp charging from the Rover Elite
will be the respective amp rating. The Rover
Elite will current limit any excess amperage
than the rating of the controller, however, be
cautious as this might create excess heat and
put the controller in an internal/external
temperature protection mode which will halt
the controller performance until it can cool
down and function normally again.
Whether connecting the system for the first
time or operating it for a while, you may
experience an E01 error if the controller does
not actually detect a battery and assumes it to
be under-discharged. This can happen in an
accidental line break or failure to connect it
correctly the first time. This will not damage
the controller, but you will need to make sure
the battery voltage is the same as the battery
terminal voltage or check for continuity. Once
fixed, normal operation should continue.

For best controller performance, it is recommended that these
tasks be performed from time to time.
1.Check wiring going into the charge controller and make sure
there is no wire damage or wear.
2.Tighten all terminals and inspect any loose, broken, or burnt up
connections.
3.Occasionally clean the case using a damp cloth.
