Rich Solar Renogy 500A Battery Monitor with Shunt Easy Installation

RS-BM500 Battery Monitor with Remote Display

The RS-BM500 is a precision battery shunt and remote display system that gives you clear, real-time insight into battery voltage, current and remaining capacity. Designed to be installed close to the battery with a wall-mounted remote, it helps you monitor and manage battery health without guesswork.

Benefits

• Know battery status at a glance so you can avoid unexpected failures and plan charging or load use.
• Save time troubleshooting by getting accurate current and capacity readings instead of estimating usage.
• Reduce wear on batteries by monitoring charge/discharge behavior and acting before deep discharge occurs.
• Keep the display where it’s convenient—mount the remote on a wall for easy viewing without visiting the battery bank.
• Simplify installation and maintenance with included wiring components and a clear wiring layout.

Features

• High-precision shunt that measures current and integrates capacity (Ah) tracking.
• Remote, wall-mountable display connected via included shielded cable for reliable data transmission.
• B+ connection lead included to power the shunt from the battery positive.
• Designed for installation close to the battery; the B- side of the shunt must be the sole negative connection for accurate measurement.
• Supports capacity configuration so you can set the system to match your battery bank size.
• Low quiescent power draw to minimize impact on battery during long idle periods.
