How Well Do You Know Solar Charger Controllers?

Environmentally friendly energy is an issue that everyone emphasises. Solar energy is an environmentally friendly energy that has conquered all hearts, and the development of solar energy is now very good. Solar energy is especially used by various household solar devices satellites and spaceships travelling in space use all solar energy. When solar power plants convert the heat or light energy of the sun into electrical energy, the solar charger controller is very important.

What are the main features of the solar charger controller?

1. The solar charger controller uses a single chip microcomputer and a special software to realize an intelligent control;

2. The solar charger controller uses the exact discharge control of the battery discharge data line correction. The discharge voltage is the control point corrected by the discharge rate curve, which eliminates the inaccuracy of the depth charge of the simple voltage control and corresponds to the inherent characteristics of the battery, i.e. different discharge rates have different end voltages;

3. The solar charger controller has an automatic control such as overload, deep charging, electronic short circuit, overload protection and unique anti-reverse connection protection; none of the abovementioned protective measures damage any parts and do not burn by insurance;

4. The solar charger controller uses the serial PWM charging main circuit, which reduces the voltage loss of the charging circuit compared to the charging circuit with diodes by almost half, and the charging efficiency is 3%-6% higher than for non-PWM, which increases the power take-off time; The high-speed charging of the low-load production, the normal direct charging and the automatic control mode of the maintenance charge ensure a longer service life of the system; at the same time it has a high-precision temperature compensation.

What is the PWM solar charger controller?

The PWM solar charger controller is the second generation technology and currently the largest on the market. The working method is PWM control. Compared to normal solar charger controllers, it has improved considerably and can solve the problem of battery dissatisfaction. But the solar panels are not fully charged.

What is MPPT solar charger controller?

The MPPT solar charger controller is the third generation technology, the high-end solar charger controller. The MPPT solar charger controller refers to the solar charger controller with the function "Maximum PowerPoint Tracking". It is an improved product of the PWM solar charger controller. The MPPT solar charger controller can detect the voltage and current of the solar panel in real time and continuously monitor the maximum power (P=U*I), so that the system always recharges the battery with the maximum power. The MPPT tracking efficiency is 99% and the power generation efficiency of the entire system is 97%. It also has excellent battery management. It is divided into MPPT charge and constant voltage equalization and constant voltage maintenance charge. With the advancement of technology and energy saving, the trend that MPPT solar charger controllers replace traditional PWM solar charger controllers is irreversible.

With the continuous increase in environmental awareness, people's demand for solar energy applications continues to rise. The emergence of solar charging regulators can effectively improve the efficiency of our solar energy use and reduce the cost of solar production. That is why the market is huge. Shenzhen Sumry Electronics Co., Ltd. has set itself the goal of providing its customers with reliable solar charging regulators and a perfect after-sales service so that customers can simply invest, use them with confidence and not worry.
