Renogy Monitoring Screen for DC-DC MPPT Battery Charger Series

The Renogy Monitoring Screen for DC-DC MPPT Battery Charger Series Shows Both Batteries and Lets You Adjust Charging Settings

The Renogy Monitoring Screen for DC-DC MPPT Battery Charger Series, model RMS-DCDC, is a flush-mount meter with a backlit LCD and four front buttons. It plugs into the RS485 port of a compatible Renogy DC-DC MPPT charger and shows your system's status on one screen.

It is for owners of a Renogy DC-DC MPPT charger in a 2-battery system, such as a vehicle with a starter battery and a house battery. Renogy lists the DCC30S (RBC30D1S) and DCC50S (RBC50D1S) as compatible models.

Renogy Monitoring Screen for DC-DC MPPT Battery Charger Series Features

Dual Battery Monitoring

The screen shows the charging status of your house and starter batteries, with voltage, current, kilowatts, kilowatt-hours and temperature pages. Press page up or page down to move between them.

Adjustable Charging Settings

You can program charger settings, volts and amps from the screen. Choose a battery type of sealed, gel, flooded, lithium or user, and set the current limit in 10A steps. You can also clear the kilowatt-hour total and switch between °C and °F.

Error Codes on the Display

A system error icon lights up with a code when there is a fault, such as house battery over-discharge, alternator over-voltage or reversed polarity. The manual lists each code and the steps to clear it.

Plug-and-Play RJ45 Connection

Connect the included RJ45 cable between the charger's RS485 port and the back of the screen. Renogy says the screen takes care of the rest. The manual says CAT5 or higher cable may also be used.

Flush Mount With a Clean Look

The faceplate sits flush with the mounting surface. You cut a 3.44 x 2.28 in opening, drill four pilot holes and fix the screen with the four included self-tapping screws.

Real-World Applications

Vehicle cabins. Renogy designed the meter for a clean, professional look inside vehicle cabins.

Alternator and solar charging. See whether the house battery is charging from solar, the alternator or both.

Practical Comparison

Monitoring Screen Versus Charger Indicator Lights

The charger has indicator lights for status. The screen adds numbers for voltage, current, kilowatts and temperature, error codes, and settings you can change.

Buyer Guidance

12V Systems and Compatible Chargers

The manual says the DC-DC chargers are suitable for 12V battery banks only. The screen should not be connected to other DC-DC chargers or systems.

Mounting Location

Renogy recommends at least 2 in (50 mm) of clearance behind the unit for the bend of the RJ45 cable. The screen should not be exposed to direct sunlight, rain, snow, moisture or liquids. Check for wires or obstacles behind the surface before drilling.

This May Be A Good Fit If

• You use a compatible Renogy DC-DC MPPT charger
• You want to watch a house and starter battery in one place
• You want to change battery type or current limit from the screen
