The on-chip adaptive battery can automatically adjust the charging current according to the output capacity of the input power source. Therefore, the SD05CRMA is very suitable for solar power systems or applications that need to charge lithium-ion batteries or lithium-polymer batteries. Input power with limited output capacity.
If your solar panel is 5V, then you can use it directly. Of course, the module can also be powered by a 5V DC power supply.

This MPPT solar controller features adaptive charging, adjusting current based on input capability. It's suitable for systems with limited output capacity, such as 3.7V Li-ion or lithium polymer batteries (4.2V) connected to solar panels (6V-48V). This power adapter is ideal for mobile power supplies and DC power sources.

Features a fully charged or battery failure status indicator, with a 'CR' LED that shows charge status. Compatible with Li-ion and Li-Polymer batteries (3.7V/4.2V). Input DC range: 4.4-6V.

Charging profile includes pre-charge constant current, then constant voltage mode, with phases: 4.2V termination, and battery voltage monitoring.

Adjustable current: modify resistor R1 to change output current from 0.1A (11.8K) to 1A (1.47K), suitable for a range of applications.

This MPPT solar controller module features undervoltage lockout (UVLO) protection for Li-ion/Li-Polymer batteries. It also includes automatic recharge, overcharge termination, and can handle 3.7V-4.2V battery input with 6V-48V solar panel output.
