Solar System Controller Module with Solar Energy Management Module 6V ~ 24V

Description:

The solar panel controller module is designed for use with 6V to 24V panels. It can charge 3.7V Li batteries from the panel or via USB. The module provides an output voltage of 5V with a capacity of 1A.

The module has an intelligent system for the best possible selection of the panel load in order to obtain the highest possible power MPPT (Maximum Power Point Tracking).

It has multiple safety features which allows you to use solar power safely.

• MPPT (Maximum Power Point Tracking) support, ensuring maximum efficiency.
• Battery charging from panel or USB.
• 6V - 24V solar panels.
• On board MPPT switch.
• Two 5V goldpin output voltage connectors and USB.
• Includes high quality capacitors to minimise interference.
• Battery holder for type 14500 batteries and PH2.0 connector.
• LED indicators for monitoring module operation.
• Protection circuits: anti overcharge / anti over discharge / reverse connection / temperature / over current.

SAFETY NOTES

Li-ion and Li-po batteries are quite unstable. They can cause fire, personal injury or property damage if not charged or used correctly.
Do not connect the terminals in reverse when charging or discharging batteries.
Do not use an inferior charger/charging panel to charge the battery.
Do not mix old batteries with new batteries, avoid using batteries of different brands.
When buying a lithium battery, always make sure that the battery specification is compatible with the expansion card. Choose batteries from an official manufacturer and ensure that the batteries will operate stably and safely by performing an ageing test.
Lithium batteries have a limited life span and will deteriorate over time. Replace with new ones when the batteries have reached their maximum life cycle or have been in service for more than two years, whichever comes first.
