WARNING

03
CAUTION
Your Renogy monitoring screen is designed for
indoor/compartment installation. DO NOT expose it to direct
sunlight, rain, snow, moisture, or liquids of any type.
DO NOT puncture, drop, crush, burn, penetrate, or strike the
monitoring screen.
The Renogy monitoring screen is only compatible with
Renogy Smart Lithium Iron Phosphate Batteries. DO NOT
attempt to connect the monitoring screen to other batteries or
systems.

General Information
Comprehensive Protection
Easy Operation
The Renogy Monitoring Screen for Smart Lithium Battery
Series is a high precision meter designed for Smart Lithium
Iron Phosphate Batteries in off-grid energy storage systems.
Instead of measuring the current flowing in/out of the battery
bank, it can communicate directly with the battery management
system (BMS) and obtain more accurate state of charge (SoC)
readings compared to traditional battery monitors. Other
battery bank information including voltage, current, capacity,
remaining time, error code, and number of paralleled batteries
are also available on the monitoring screen to help users avoid
abnormal conditions and extend the lifetime of battery bank.
Plug and Play
Simply connect the monitoring screen to the battery bank
using an RJ45 communication cable for real-time
monitoring.
Accurate Readings
Obtains battery bank status directly from the battery
management system for precise tracking and prediction.
Shows detailed battery bank information at the push of a
button without the need of system configuration and
calibration.
Displays straightforward error codes for the quick
recognition of potential abnormal conditions and improper
operation.

Additional Components
RJ45 Communication Cable
The RJ45 Communication
Cable (5m/16.4ft) is used to
connect the monitoring
screen to the battery bank
for power supply and data
transmission.
Self-tapping Screws (4)
The Self-tapping Screws
(M2.9x13) are used to fix
the monitoring screen on
the mounting surface.

3. Cut out a rectangular area for the monitoring screen on the
mounting surface with a jigsaw.
5. Place the monitoring screen into the cut-out area and align the
mounting holes on the monitoring screen with the pre-drilled
screw holes.
6. Affix the monitoring screen on the mounting surface with the
included four self-tapping screws.
7. Re-attach the snap-fit Front Cover Plate to the monitoring screen.
4. Pre-drill four screw holes on the mounting surface with a drill.
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 of
operational controls and battery information. The RJ45
Communication Port on the monitoring screen is accessible from
the back of the unit. Clearance of at least 2 inch (50 mm) behind the
unit is recommended to allow for the bending radius of the RJ45
Communication Cable that connects to the monitoring screen.
Before installing the monitoring screen, it is recommended to have
the following tools available:

Please connect the monitoring screen to the UP Communication
Port of the battery using the included RJ45 Communication
Cable to obtain detailed battery information from the battery
management system.

If you are using the monitoring screen with a parallel battery
bank, the battery management systems of paralleled batteries
must be connected to enable proper communication with the
battery bank. Please connect the LINK Communication Ports of
the former batteries to the UP Communication Ports of the latter
ones using CAT5 (or above) Ethernet cables (not included).

DO NOT string the batteries in series. Doing so may cause
catastrophic failure.
DO NOT string different types of batteries, batteries with
different rated capacities, or batteries from different
manufacturers in parallel.
Please avoid too high a voltage difference between
paralleled batteries, despite the auto-balancing function, to
avoid triggering the over-current protection.
In parallel battery banks, the cables between each battery
should be of equal length to ensure that all the batteries in
the system can work together equally.
It is not recommended to connect more than 4 batteries in
parallel if taking advantages of the auto-balancing function.
Please leave the battery or battery bank in shelf mode during
installation. Take care to activate the battery or the battery
bank using the monitoring screen ONLY after making sure all
the connections are correct and secure.
Ethernet crossover cables are not compatible with Renogy
systems. Connecting batteries using Ethernet crossover
cables may result in damage to the battery management
system.
Please make sure that the battery or the battery bank has
been activated using the monitoring screen or the Activation
Switch that comes with the battery. Otherwise, no
information will be displayed.

The present voltage indicates the real-time terminal voltage of
the battery. If the monitoring screen is connected to a battery
bank, the present voltage will be the average terminal voltage of
the batteries in the battery bank.
The present current indicates the real-time current flowing
through the battery or the battery bank. Positive values indicate
that the charge current is higher than the discharge current,
while negative values indicate that the discharge current is
higher than the charge current.

The capacity indicates the maximum capacity the battery or
battery bank can deliver under standard discharge conditions
when fully charged. The capacity will diminish gradually with the
cycling of the battery or the battery bank.
Capacity (Ah)
The state of charge indicates the real-time charge level of the
battery relative to its capacity. If the monitoring screen is
connected to a battery bank, the state of charge will be the
average state of charge of the batteries in the battery bank.
The number of paralleled batteries indicates the number of
batteries connected in parallel in the battery bank. If a battery is
used individually, then the number of paralleled batteries will be 1.

The remaining time indicates the time remaining before the battery,
or the battery bank, will require a recharge based on current usage
rate. If the battery is being charged, the remaining time will not
display. If the low voltage warning is triggered during discharge, the
remaining time will be 0.0H.
The battery level indicates the charge level of the battery relative to
its capacity using five segments. If the present current is positive,
the battery segments will blink to indicate the current charge status.
Once the battery is fully charged, all battery segments will remain
solid. If the monitoring screen is connected to a battery bank, the
battery level will indicate the average battery level of the batteries
in the battery bank.
The error code indicates potentially abnormal conditions of the
battery or battery bank. If the battery or the battery bank operates
normally, the error code will not display. If the battery or the battery
bank is involved with multiple potential abnormal conditions, the
monitoring screen will scroll display multiple error codes.

Paralleled batteries MUST be connected properly using CAT5 (or
above) Ethernet cables before connecting to the monitoring
screen to reflect an accurate status of the battery bank.
If the number of paralleled batteries increases after the
monitoring screen has been connected to the battery or the
battery bank, please long press the Page Up Button and the
Page Down Button at the same time for 3 seconds to reset the
monitoring screen and update the battery bank information.
The monitoring screen is ONLY able to obtain the information
of battery banks with no more than 9 paralleled batteries.
After connecting the monitoring screen to the battery or battery
bank, please press the Power Button on the monitoring screen
first to activate the battery or battery bank. The backlight will
then be lit and the LCD Display will show the present voltage. If
no operations are made within 25 seconds, the backlight will go
out and the LCD Display will scroll through the present voltage,
present current, capacity, and state of charge.
To display a specific parameter, please press the Page Up
Button or the Page Down Button repeatedly until the desired
parameter shows up. The backlight will light up once the Page
Up Button or the Page Down Button are pressed. If no
operations are made in 15 seconds, the backlight will go out and
the LCD Display will continue scrolling through the present
voltage, present current, capacity and state of charge.
Prior to long periods of storage, please long press the Power
Button on the monitoring screen for 3 seconds to put the battery
or battery bank into shelf mode.
