TC30 is a battery monitor designed specifically for RVs, integrating high-definition display, smart connectivity, and high-precision sampling into one compact device. It serves as your reliable energy management companion during travels, providing accurate battery data and power usage history through an intuitive large screen and mobile app. With TC30, RV power management becomes clearer and more controllable than ever before.

Equipped with a high-resolution IPS full-touch color screen, the TC30 delivers vivid colors and an ultra-wide viewing angle. The display shows voltage, current, power, remaining capacity, and estimated usage time based on current consumption—all at a glance. It also plots real-time power and State of Charge (SOC) curves, helping you understand energy trends and plan usage efficiently.

Built-in Bluetooth and Wi-Fi enable seamless connectivity. Using the companion mobile app, you can monitor real-time data and historical trends from inside or outside the RV—no need to stay near the device. Whether at a campsite, at home, or on the go, you can always keep track of your RV’s battery status remotely and conveniently.

An integrated ambient light sensor automatically adjusts screen brightness for optimal visibility in any lighting condition, avoiding glare. The device also features customizable alarms for high/low voltage, low capacity, and low SOC. If anomalies occur, it triggers visual icons and an audible buzzer to protect the battery from over-discharge or overcharge risks.

Equipped with a standard RS485 interface and support for customized communication protocols, it can seamlessly connect to various RV battery management systems (BMS) to display battery data collected by the BMS. The embedded installation design allows it to integrate perfectly into the RV control panel, offering simple setup, a clean and aesthetically pleasing appearance, while saving valuable space.

Battery monitors can be used in any scenario involving battery packs. They continuously track the status of the battery pack and display key parameters such as remaining charge, current voltage, current, power, and other relevant data. This allows users to monitor battery health in real time, helping to protect the battery and extend its lifespan.

It is compatible with mainstream battery types on the market, such as lead-acid batteries, lithium-ion batteries, lithium iron phosphate batteries, sodium batteries, etc.
