I Product Overview
5V-24V Solar Panel, with MPPT, DC-044 Power Jack and KF128L-2P Terminal Block
Solar Energy Manager is a solar power management module, which can charge the 3.7V 18650 lithium battery through solar panel or USB port.The module features MPPT (Maximum Power Point Tracking) and protection functions of battery charging and discharging. MPPT power point tracking can automatically adjust the charging power according to the input voltage, taking advantage of solar energy more efficiently. The protection circuit of charging and discharging can monitor the battery voltage in real time, preventing the battery from overcharging and over-discharging. It can protect the battery and prolong the battery life. Due to its excellent stability and efficient management of charging and discharging, it can be used in solar power generation, low-power IoT and other environmental protection projects.

Resource Profile
Figure 4-1 Solar Energy Manager Resource Profile figure
①Solar charging connector: can be wired to the solar panel through the DC-044 power jack.
②Solar charging connector: can be wired to the solar panel through the terminal.
③USB charging connector: can use the power adapter to charge the battery through the TYPE-C data cable.
④The switch of Battery，This switch should be turned to "ON" when charging the battery and outputs 5V and 3.3V.
⑤USB output port: output 5V/2A power through the USB port.
⑥Output boost chip: CN5305 boost chip.
⑦Pin header output port: output 5V/2A and 3.3V/1A power through pin header of 2.54mm pitch.
⑧Output status indicator.
⑨3.7V lithium battery expansion connector: 3.7V lithium battery can be expanded through the PH-2PWB connector, and the expanded lithium battery can be charged and discharged.
⑩18650 lithium battery holder.
⑪The indicator of battery capacity.
⑫External battery (see ⑨in Figure 4-1) reverse connection warning indicator: lights up to issue a warning when the battery is reversely connected.
⑬The warning indicator for battery reverse connection : lights up to warn when the battery is reversely connected.
⑭Lithium battery protection circuit: lithium battery overcurrent, overdischarge, overcharge protection circuit.
⑮ CN3791 solar charging chip.
⑯ DIP switch for setting MPPT voltage : Solar charging MPPT voltage setting DIP switch, set the MPPT voltage according to the charging voltage, which can improve the charging efficiency. The MPPT setting voltage should be less than or equal to the input voltage. The solar panel input and USB TYPE-C input cannot charge the battery at the same time, only one port can be selected to charge the lithium battery at any time.
⑰Lithium battery charging indicator: Charge: the light is on when the lithium battery is charged through the solar panel or USB connector; Done: the light is on when the lithium battery is charged (Done flashes when the lithium battery is disconnected or not connected during the charging process).
⑱Warning indicator for solar panel reverse connection: When the solar panel is wired to the Solar Energy Manager, if the positive and negative poles are reversed, the warning indicator will light up to give an alarm.
⑲ Lead out the battery charging status and battery power pins (the pin header is not soldered).
