High-performance MPPT solar charge controller with 100 A charging current for medium to large photovoltaic systems.
The EPEVER TEP10425 controller from the TEP series represents an advanced solution for charge management in solar systems with 12/24/48 V voltage. With a maximum charging current of 100 A and support for input voltage up to 225 V at 25 °C, it is ideal for caravans, boats, industrial monitoring, and small to medium photovoltaic installations. The controller achieves peak MPPT tracking efficiency of 99.5% and maximum conversion efficiency of 98.4%, ensuring optimal utilization of solar energy.
The device supports two independent PV inputs and offers flexible configuration including parallel connection of up to 6 units via the built-in CAN port. The unique battery-less mode allows direct load power supply with sufficient sunlight. The controller is compatible with various battery types including AGM, gel, flooded, and LiFePO4, while the built-in BMS communication port ensures reliable charge and discharge management of lithium batteries.
Advanced features and communication
The controller offers comprehensive real-time monitoring with data recording function, event logging, and energy production statistics. Communication is via isolated RS-485 interface with 5 V DC/200 mA power supply (RJ-45 connector). Optionally, modules for Bluetooth, WiFi, TCP, or 4G communication can be connected for remote monitoring and system management.
Protection and reliability
The device is equipped with comprehensive electronic protection and complies with international standards EN/IEC61000-6-2, EN/IEC61000-6-4, EN/IEC62109-1, and IEC62321. Operating temperature range from -25 °C to +60 °C and compartmentalized design ensure high dust resistance and reliable operation even in demanding conditions. The controller uses common negative grounding and offers low standby power consumption.
Flexible charging
Three-stage charge control with adjustable temperature compensation -3 mV/°C/2 V ensures optimal battery care. Output voltage range 8 V to 62 V covers a wide spectrum of applications. With communication disabled, consumption drops to only 48 mA/12 V, 25 mA/24 V, or 14 mA/48 V.
