The continuous popularization of solar photovoltaics uses solar photovoltaic power supply generation in many fields now, which is convenient, energy-saving and efficient. But no matter in which field, solar controllers are definitely needed. The solar controller protects the battery from charge and discharge, as well as automatic adjustment.
Solar panels are photovoltaic devices, the main part of which is semiconductor materials. When the solar panel is irradiated with light, a photoelectric effect generates a current. Due to the properties and limitations of materials and light, the generated current is also a volatility curve. If the generated current is charged into the battery or supplies power to the load directly, it is easy to cause damage to the battery charger and the load which reduces their life expectancy. Therefore, we must first send the electric current into the solar controller, adjust it with a series of dedicated chip circuits digitally, and add multi-stage charge and discharge protection. At the same time, adopt our unique control technology of adaptive three-stage charging mode to ensure the battery, load operation safety and service life. When the load is supplied to the load, the current of the battery is first flowed into the solar controller. After it is adjusted, the current is sent to the load. The purpose of this is not only to stabilize the discharge current but also to ensure that the battery is not over-discharged. In addition, a series of monitoring protections for the load and battery are available.
To use AC power equipment, it is also necessary to add the power inverter to AC before the load.
1.The solar control system uses a single-chip computer and special software to achieve intelligent control.
2.Accurate discharge control corrected by battery discharge rate characteristics. The discharge terminal voltage is a control point corrected by the discharge rate curve, which eliminates the inaccuracy of the simple voltage control over-discharge and conforms to the inherent characteristics of the battery. This means that different discharge rates have different end voltages.
3.The solar control system has automatic control such as overcharge, over discharge, electronic short circuit, overload protection, and unique anti-reverse protection. The above protective measures do not damage any parts and do not burn insurance.
4.The series PWM charging main circuit is adopted, so that the voltage loss of the charging circuit is reduced by nearly half compared with the charging circuit using the diode. The charging efficiency is 3%-6% higher than non-PWM, which increases the power consumption time. The normal direct charging and the floating charge automatic control mode make the system have a longer service life. At the same time, it has high precision temperature compensation.
5.The intuitive LED lighting tube indicates the current battery status, allowing the user to understand the usage status.
6.All control uses industrial grade chips, which can run freely in cold, high temperature and humid environment. At the same time, the crystal timing control is used, and the timing control is accurate.
