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.

2. Use the monitoring screen as a template to mark the screw holes
and trace the cut-out area on the mounting surface with a pencil.
1. Remove the snap-fit Front Cover Plate from the monitoring
screen.
3. Cut out a rectangle area for the monitoring screen on the
mounting surface with a jigsaw. You may also use the cut out
dimension specified after Step 2.
5. Put the monitoring screen into the cut-out area and align the
mounting holes on the monitoring screen with the pre-drilled
screw holes.
6. Fix the monitoring screen on the mounting surface with the
included four self-tapping screws.

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.
