What is charging technology in  solar portable kits

The key of the solar kits quality is how to charging power quickly and safety, This is directly related to the built-in charging circuit. A low quality charging module often leads to can not charge, full of dissatisfaction, or overcharge caused battery damage or explosion, resulting in adverse effects. Here are some common ways to make an introduction to charging

1. PWM charging method, which is the mainstream of the market charging method, the use of three-phase charging, whether it is lead-acid batteries or lithium batteries can play a very good protective effect, when the battery voltage rises to the maximum charging voltage, the controller will automatically reduce Charge current to prevent the battery voltage is too high. When the battery is full, it floats to charge, ensuring the battery is fully charged. When the battery is fully charged, it will stop charging. Even if the solar panel does not pull down, it will not be damaged

2. MPPT charging method: This charging method is highly efficient, complicated in technology and high in cost. In the current market conditions of intense competition, rarely used. Used in some foreign high-end small system above.

3. Switching charging mode: This charging technology hardware is simple, mature technology, but poor reliability, the battery damage is relatively large. Switching charging principle is to use solar panels to charge the battery, when reached the highest charge voltage, stop charging, when the battery voltage drops to a certain voltage, and then reconnect the charge. Repeat this process.

Conclusion, the choice of small solar power generation system is best to choose the PWM charging method or MPPT charging method.
