It regulates the panel voltage using pulse-width modulation so that the panel operates close to its optimal operating point, where it delivers the most energy. The voltage at the integrated control pin is stabilized at 1.205 V; an externally connected resistor divider determines the actual panel voltage at which this ideal point is reached.\u003c\/p\u003e \u003cp\u003eCharging takes place in several stages. When the cell is deeply discharged, the module starts with reduced precharging. As soon as the cell voltage exceeds a defined threshold, it switches to constant-current charging. As the voltage approaches the final value of 4.2 V, the current continuously decreases until charging is complete at a low residual current. If the battery voltage later falls below a defined value, a new charging cycle starts automatically without manual intervention.\u003c\/p\u003e \u003cp\u003eFour identical JST-PH connectors are available for connection, with two on opposite sides for the solar input and battery output. Since they are internally connected in parallel, additional cables, a second panel, or other consumers can be connected directly without requiring splitters. Four solder pads on the circuit board alternatively allow direct wiring of the panel, battery, and ground. Two LEDs indicate whether charging is in progress or complete.\u003c\/p\u003e \u003cp\u003eThe module switches off automatically when the input voltage falls below the permitted range and enters a low-power standby mode when no panel voltage is present. Excessive battery voltage stops the charging process to protect the cell. The input voltage range from 4.5 to 28 V allows use with various types of panels; however, a solar panel with sufficient output is required for operation, as the module cannot use any other power source.\u003c\/p\u003e \u003ch3\u003eSafety Information\u003c\/h3\u003e \u003cp\u003eCheck the polarity when connecting the panel and battery; incorrect polarity will cause damage.
