Ideal for hybrid setups, backup power stations, or upgrading existing solar systems without rewiring. - 7 Modes for Smart Energy Control Light Control: Automatic dusk-to-dawn operation (10-min delay) for streetlights Timing Mode: Program discharge schedules (up to 23h59m) for irrigation/security systems Manual Override: Force discharge with ▼ button during emergencies Test Mode: Simulate 10-minute scenarios for system diagnostics Plus charging-only, universal, and low-voltage modes for ultimate flexibility. - Safety + Real-Time Insights：LCD backlit screen displays live data: battery voltage, PV charge/discharge currents, temperature, and error codes. Triple-layer protection instantly cuts power during surges (over 32V), short circuits, or overheating (＞65℃/149℉), safeguarding batteries and connected devices. - Pro-Level Customization：Fine-tune parameters (delays, voltage thresholds) via intuitive menus and save presets. Built-in USB ports charge phones/tablets while solar prioritizes battery charging. Rugged design withstands -35℃ to +65℃ for Arctic winters to desert summers.

Product description

Model: SA-80A

[CRITICAL NOTICE: This is a Focusing MPPT, NOT a Buck/Boost Controller] This controller provides efficient MPPT current tracking (5-10% more efficient than PWM) but it CANNOT step down voltage from a high-voltage panel. Therefore, following the exact voltage matching rules is MANDATORY to prevent permanent damage and invalidate your product coverage.

(1) VOLTAGE MATCH IS ESSENTIAL: Because there is no step-down function, you MUST match the panel voltage to the battery. NEVER use a 24V, 36V, or 48V panel to charge a 12V battery. The voltage difference will destroy the controller.

(2) REQUIRED SPECS: Use 15-23V Panel for 12V Battery Use 30-46V Panel for 24V Battery Use 45-66V Panel for 36V Battery Use 60-90V Panel for 48V Battery

(3) WIRING ORDER: You MUST connect in this exact sequence:

(4) BATTERY DETECTION: The battery MUST have a minimum charge to be detected: 12V battery: above 10V 24V battery: above 20V 36V battery: above 30V 48V battery: above 42V

Solar charge controller with the most advanced MPPT control algorithm, which can quickly capture the maximum power point of the PV array in any environment to extract the maximum energy from the solar panel and significantly improve the energy utilization in the solar system.
