The TECHFINE 40A MPPT Solar Charge Controller is designed for reliable solar power regulation in off-grid and hybrid systems. It supports automatic detection of 12V, 24V, 36V, and 48V battery systems.
Charging Technology
Utilizes Maximum Power Point Tracking (MPPT) to optimize solar panel efficiency. Supports a multi-stage charging process (bulk, absorption, float) for extended battery lifespan.
Voltage & Input Capacity
Nominal battery voltage: 12V/24V/36V/48V (auto-adaptive)
Maximum PV input voltage: 150V open circuit
Maximum PV power:
12V: 540W
24V: 1080W
36V: 1620W
48V: 2160W
Battery Compatibility
Compatible with sealed, gel, and flooded lead-acid batteries. Custom settings can be configured for lithium-based batteries.
System Monitoring
Features a high-definition backlit LCD screen for real-time system data, status, and error notifications.
Protection Functions
Provides protection against over-voltage, under-voltage, reverse polarity (solar and battery), over-current, short circuit, and over-temperature.
Communication Interface
Equipped with RS485 port for external monitoring and integration with compatible inverter systems.
Mechanical Design
Compact housing with built-in cooling fan. Dimensions: 380 × 255 × 160 mm.
