Renogy 500A Battery Monitor with Shunt

Precise, easy-to-read battery monitoring for RVs, boats, cabins and off-grid systems

The Renogy 500A Battery Monitor provides real-time, high-precision tracking of voltage, current and state of charge for a wide range of battery types. It pairs an LCD display with a 500A shunt and a 20 ft shielded cable so you can monitor battery health and usage from a distance and take action before batteries are damaged.

Benefits

• Know exactly how much charge you have left so you avoid unexpected power loss and downtime.
• Protect battery life by receiving alarms before voltage drops to harmful levels.
• Monitor battery performance from a convenient location without sitting next to the battery bank.
• Make better charging and usage decisions that extend battery longevity and reduce replacements.
• Compatible with many battery chemistries, so you can use one monitor across different systems.

Features

• Shunt-type monitoring for accurate real-time current and voltage measurement.
• LCD interface with adjustable green backlight and high-definition display of multiple parameters.
• Displays voltage, current, consumed power, remaining capacity and battery degradation rate.
• High and low capacity/current/voltage alarm settings with backlight and value flash on alarm.
• Data memory saves last readings when power is removed.
• Transparent shunt holder for easy mounting and a 20 ft (6 m) shielded cable for remote display placement.
• Works with a broad range of batteries: Lead Acid (AGM, GEL), Lithium Iron Phosphate, Lithium-ion, Nickel-metal hybrid.
