EPEVER TEP10425 solar MPPT controller 100A 12/24/48 V input 250V

EPEVER TEP10425 — High-Performance Solar Controller

For medium to large photovoltaic systems, ensuring efficient charge management and maximum utilization of solar energy is crucial. The EPEVER TEP10425 controller is designed for systems with a voltage of 12/24/48 V, offering a maximum charging current of 100 A and supporting input voltage up to 225 V at 25 °C. With a top-notch MPPT tracking efficiency of 99.5% and a maximum conversion efficiency of 98.4%, this controller optimizes the performance of solar panels. Its combination of high flexibility, battery-free mode, and compatibility with various battery types makes it an ideal choice for caravans, boats, industrial applications, and home energy systems.

Dual PV Inputs and Parallel Expandability

The controller supports two independent PV inputs, allowing flexible connection of different solar panel configurations. With the ability to connect up to 6 units in parallel via the built-in CAN port, the system can meet higher energy demands. This expandability is perfect for growing photovoltaic systems where easy scalability is required.

Battery-Free Mode and Variable Load

The unique battery-free mode enables direct power supply to the load from PV panels during sufficient sunlight. This feature is practical for applications where energy storage is unnecessary, such as powering pumps or lighting. The output voltage range of 8 V to 62 V ensures compatibility with a wide range of devices.

Advanced Control and Monitoring

Thanks to the isolated RS-485 interface, Bluetooth, Wi-Fi, TCP, or 4G communication modules can be connected for remote monitoring and system management. Additionally, the controller offers advanced features for data recording, event logging, and energy production statistics, helping users optimize performance and monitor their system's status in real time.

Mechanical Durability and Protection

The EPEVER TEP10425 controller complies with international standards EN/IEC61000-6-2, EN/IEC61000-6-4, EN/IEC62109-1, and IEC62321, ensuring reliability and safety. With IP20 protection and an operating temperature range of -25 °C to +60 °C, it is resistant to dust and operates reliably even in challenging conditions. Its low standby power consumption also makes this controller energy-efficient.
