The product in the image is a Felicity Solar Charge Controller. These controllers come in various models, including both MPPT (Maximum Power Point Tracking) and PWM (Pulse Width Modulation) technologies, with different amperage ratings.
Specifications
- Technology: Intelligent Maximum Power Point Tracking (MPPT) technology, which increases charging efficiency by 25% to 30%.
- System Voltage: Compatible with 12V, 24V, or 48V PV systems (auto-detection for lead-acid, manual setting for lithium).
- Maximum Efficiency: Up to 98%.
- Charging Algorithm: Three-stage charging (Bulk, Absorption, Float) optimizes battery performance (two-stage for lithium batteries).
- Current Options: Available in various maximum charging currents, such as 30A, 45A, 60A, 80A, 100A, and 120A.
- Protections: Includes features like reverse polarity protection, overcharging, and over-discharging protection.
- Communication: Integrated intelligent slot compatible with MODBUS communication.
- Display: Often features an LCD screen displaying charge voltage, current, and battery status.
