Renogy 500A Battery Monitor with Shunt

Renogy 500A Battery Monitor with Shunt

The Renogy 500A Battery Monitor is designed to monitor performance for most kinds of batteries. Its high-precision measurements eliminate the guesswork from battery usage and improve your battery bank’s overall performance and longevity. This universal monitor works with voltages from 10V to 120V and currents up to 500A, making it suitable for a huge range of solar, RV, marine, and off-grid systems.

1% Accuracy Shunt Measurement

The shunt-type design delivers far more accurate real-time voltage and current-draw readings than voltage-only meters, with ±1% accuracy across capacity, current, and voltage — giving you a true picture of your battery’s state of charge.

Protect Your Batteries

Programmable high and low capacity alarms guard against over-discharge. When an alarm triggers, the backlight and voltage value flash on screen to alert you before you hit the cut-off voltage — helping extend battery life.

Easy-to-Read Display

The high-definition backlit LCD displays multiple parameters at a glance — voltage, current, consumed power, battery capacity, and battery degradation rate — with adjustable brightness for any environment.

Low Power Consumption & Data Storage

The backlight automatically shuts off when charging current is below 100mA, with just 1mA standby dissipation. Built-in data storage automatically saves your last reading whenever the power is turned off.

Easy to Install

The package includes everything you need — LCD interface, 500A shunt, transparent shunt holder, 20ft shielded cable, and B+ wire. The shunt holder makes mounting simple, while the long shielded cable lets you monitor your battery status from a distance.

Important Note

Avoid prolonged exposure of the monitor to direct sunlight or high levels of ultraviolet radiation, and avoid storing or using it in extreme cold (below -10°C) or heat (above 60°C), as this can shorten the LCD’s lifespan.

Take the guesswork out of your power system with the Renogy 500A Battery Monitor with Shunt — accurate, easy-to-install monitoring that protects and extends the life of your solar, RV, marine, or off-grid battery bank.
