More info


Solar Power Manager 5 V is a compact high-power solar power management module with a 5 V output voltage. It has the MPPT (Maximum Power Point Tracking) function, which maximizes solar panel efficiency (up to 89% efficiency). The module is based on the CN3065 solar management system. The module can provide a charging current up to 900 mA for a 3.7 V battery with a USB charger or solar panel. The module can provide power supply in various projects requiring low power. The plate also includes various safety functions, such as protection against reverse connection of the battery / solar panel, protection against excessive temperature and excessive current / short circuit, which significantly improves the stability and security of the system.

The board has no protection against excessive battery discharge. In order to increase the safety of the system, use a Lipo battery with built-in protection.

The board has a number of signaling diodes that make it easier to control the system's operation. It can be used in such projects as intelligent environmental monitoring system, solar powered works, small solar street lamp or Power Bank solar charged.
