EPEVER Remote Monitoring Devices
Off-grid solar systems rely on solar panels and batteries to provide electricity for homes, businesses, or other applications that are not connected to the traditional power grid. In such systems, it is important to monitor various parameters, such as the PV (photovoltaic) voltage, battery current and voltage, load current, and other critical system data. This is where a remote monitoring device comes in handy.
A remote monitoring device, such as EPEVER’s MT50, MT75, MT91, or MT92, provides an easy and convenient way to monitor and control off-grid solar systems. These devices can be connected to EPEVER’s solar charge controllers or inverters to provide real-time data on system performance, including power output, charging status, and system errors. This allows users to quickly identify and resolve any issues that may arise, ensuring that their solar systems are operating at peak efficiency.
Additionally, a remote monitoring device enables users to remotely configure and program their solar systems. Remote here means a wired connection with limited distance. This is particularly useful for off-grid systems that are located in remote or difficult-to-reach locations, where regular maintenance may be challenging.
EPEVER remote monitoring devices have communication ports and real-time displays of fault alarms, making it easy to read real-time parameters. They’re designed for easy installation and operation, and feature an ON/OFF button to control the load output.
The MT50 is a remote display unit compatible with LSxB(P), VSxBN, XTRA, GoMate, TracerAN, iTracer and TracerxBN(P) controllers. It supports the latest solar controller communication protocol and voltage technology standards. The device automatically identifies and displays the type, model, and relevant parameter data of controllers. It features a large multifunction LCD screen that displays operational data and connection device working status in digital, graphic, and textual forms. The device also offers real-time data monitoring and remote load switchover of the controllers. Users can browse and modify device parameters, charge control parameters, and load control parameters using six navigation function keys that provide direct, convenient, and rapid operation. The device has RS485 communication capabilities that enable communication over longer distances.
The MT75 is similar to the MT50, but it has the added functionality of monitoring both the EPEVER solar charge controller and inverter on one screen simultaneously. The device features a 4.7-inch LCD screen that displays real-time dynamic system data and visually displays error codes, warnings, and faults. It also includes a Load ON/OFF button that enables direct control of the load output, a dry contact output, and an enable switch design. The device can remotely control the inverter ON or OFF and is compatible with various EPEVER devices. It features dual RJ45 communication ports and communicates via Modbus RTU.
The MT91 is a remote meter specifically designed for EPEVER inverters. The device displays real-time parameters of the inverter on one screen and supports parameter configuration by button operations to make it suitable for different requirements. It features a dual interface design that is friendly to connect with EPEVER inverters and other optional modules. The device has an LCD screen that displays real-time dynamic system data, error codes, warnings, and faults. It also includes a Load ON/OFF button that enables direct control of the load output. The device is easy to install and operate, and it has a friendly operation interface.
The MT92 is a remote meter that displays real-time parameters of MSC-N series controllers on one screen. The device supports parameter configuration by button operations, making it suitable for different requirements. It features a dual interface design that is friendly to connect with different EPEVER devices. The device has an LCD screen that displays real-time dynamic system data, error codes, warnings, and faults. It also includes a Load ON/OFF button that enables direct control of the load output. The device is easy to install and operate, and it has a friendly operation interface.
The MT11 is a remote meter that matches the DuoRacer series controllers. The device can monitor the controller’s running data and working status. It has an easy installation process and is easy to operate. It features a real-time display of fault alarms and locally readable real-time parameters. The device is powered by the controller directly.
