General Safety Information
Inverter Safety
Installation and wiring must comply with the Local and
National Electric Codes (NEC) and must be done by a
certified technician.
Read all the instructions and cautions in the manual before
beginning the installation. There are no serviceable parts for
this inverter.
Do NOT disassemble or attempt to repair the monitoring screen.
Make sure all connections going into and from the inverter
are tight. There may be sparks when making connections,
therefore, make sure there are not flammable materials or
gases near installation.
The inverters are suitable for 12V Battery Banks ONLY.
ALWAYS make sure inverter is in OFF position and
disconnect all AC and DC connections when working on any
circuit associated with the inverter.
NEVER connect the AC output of the unit directly to an
Electrical Breaker Panel/ Load Centre which is also fed from
the utility power / generator.
When connecting battery terminals, ensure the polarity of the
battery connections is correct. Incorrect polarity may cause
permanent damage to the unit.
Be careful when touching bare terminals of capacitors as
they may retain high lethal voltages even after power is
removed.

03
The 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 monitoring Screen is only compatible with Renogy PGH
Inverter Series. DO NOT attempt connecting the monitoring
screen to other inverters or systems.
The RMS-PGH will operate when the PGH Inverter is in the
ON or REM position. Only in the REM position, will the
RMS-PGH be able to manually turn the inverter ON/OFF in
addition to monitoring the inverter.
Changing the frequency (50/60Hz) or the power mode
(Normal/Eco) will need to be done physically on the inverter.
The inverter then needs to be rebooted for the changes to
take effect on the monitoring screen.
In order to read the parameters of the inverter correctly,
1. The switch must be in the ON or REM position and the
COMM port correctly connected to the RJ45 cable.
2. The REMOTE port is correctly connected to the RJ12
communication cable.
DO NOT open, dismantle, or modify the monitoring screen.

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.
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.
The RMS-PGH requires a flush mount installation. The
RMS-PGH’s faceplate will be flush with the mounting surface
and the body of the meter.
CAUTION
WARNING
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/RJ12 Communication ports on the monitoring screen
are 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/RJ12 Communication Cables that
connect to the monitoring screen.
Before installing the monitoring screen, it is recommended to
have the following tools available:
