Rich Solar RS-BM500BZ 500A Battery Monitor with Shunt
The Rich Solar RS-BM500BZ 500 Amp Battery Monitor with Shunt gives RV, van, marine, cabin, solar, and off-grid battery systems a clearer view of battery status. Designed for 8–120V battery systems, this monitor uses a 500A shunt and remote display to help track voltage, current, and battery capacity with ±1.0% accuracy, making it easier to understand how much usable power is available before your system runs low.
Product Overview
The RS-BM500BZ is built for customers who want more than a rough battery voltage reading. By measuring current through a shunt, the monitor can give a clearer picture of battery capacity, charge and discharge activity, voltage, and system usage.
This makes it a practical upgrade for RV battery banks, camper vans, boats, cabins, solar battery systems, inverter setups, and off-grid builds where knowing remaining battery capacity helps prevent unexpected shutdowns.
Built for Real Battery-System Visibility
Battery voltage alone does not always tell the full story, especially with lithium batteries and larger DC systems. A shunt-based monitor helps customers track the movement of power in and out of the battery bank, making it easier to manage daily energy use, charging performance, and remaining capacity.
Key Features That Matter
This description keeps the focus on what customers actually need from a battery monitor: accurate readings, a clear display, wide voltage compatibility, 500A shunt measurement, and a cleaner way to understand battery-bank status.
The remote display helps show key battery information in one place, including capacity, voltage, current, battery percentage, and usage status. This makes it easier to check your system at a glance without opening a battery compartment.
The wide 8–120V battery voltage range makes this monitor useful across many DC battery bank setups, including common RV, marine, cabin, solar, backup, and off-grid electrical systems.
The RS-BM500BZ is listed with ±1.0% capacity accuracy, ±1.0% voltage accuracy, and ±1.0% current accuracy, helping customers get more dependable battery information than a simple voltage-only meter.
This monitor is a practical add-on for customers building or upgrading battery banks for solar charging, inverter power, RV electrical systems, boat power, backup setups, or off-grid energy storage.
How the Shunt-Based Wiring Works
The shunt is installed close to the battery on the negative side of the system, while the remote display is mounted where it is easy to read. This setup lets the monitor measure battery current flow accurately while keeping the display visible in a convenient location.
Important Install Notes
- Mount the shunt as close to the battery as possible.
- The remote display is intended to be mounted on a wall or panel.
- The battery negative terminal should connect directly to the B- side of the shunt.
- For accurate readings, there should be no other connections directly to the negative battery terminal.
- The included B+ wire connects the shunt’s B+ terminal to the positive side of the battery.
- The shunt connects to the remote display using the included shielded cable.
