Introduction

The DFRobot Solar Power Manager series are designed for IoT projects and renewable energy projects, providing safe and high-efficiency embedded solar power management modules for makers and application engineers.

Solar Power Manager 5V is a small power and high-efficiency solar power management module designed for 5V solar panel.
It features as MPPT (Maximum Power Point Tracking) function, maximizing the efficiency of the solar panel. The module can provide up to 900mA charging current to 3.7V Li battery with USB charger or solar panel. The ON/OFF controllable DC-DC converters with 5V 1A output satisfies the needs of various solar power projects and low-power applications. The module also employs various protection functions for battery, solar panel and output, which greatly improves the stability and safety of your solar projects.
 
Check the brief specification for all Solar Power Manager Series Products.
 
Version History
V1.0: It is highly recommended to use a 3.7V lipo battery with protection circuits to improve battery safety.
V1.1(Newest): Battery (BAT IN) overcurrent and overdischarge protection is added to improve battery safety. It can be use for 3.7 lipo battery no matter it is packed with protection circuits or not.

Surprisingly this power manager is heavier than I expected, very well crafted and has been consistent in its output since my purchase. Getting creative I have found a wide range of applications I can use it in. From a rechargeable porch light to a countertop dual (x2) 18650 battery charger.

Recomendable, perfecto para alimentar RBP o ESP32

Shipping was fast and the packaging is nice! When you usually buy this type thing from other vendors it’s usually a plain esd bag, but they put some time and effort into the presentation and was a nice surprise. Haven’t tested yet but looks great! Happy about finding out about this company!
