How to Choose the Working Mode of The Off Grid Inverter​?
In an off-grid system with utility power complementation, there are two types of energy output sides, photovoltaic power generation and utility power. The load is energy consumption, and the battery can not only absorb electricity, but also release electricity for the load. Therefore, in the off-grid system, there are three sources of electricity for the load: mains, battery priority, and photovoltaic; there are also three battery charging modes: Electric charging, photovoltaic charging, mains and photovoltaic charging. The application scenarios and requirements of photovoltaic off-grid users are very different, so different modes should be selected according to the actual needs of users to maximize photovoltaics and meet customer requirements as much as possible.
How to Choose an Off-grid Inverter?

It can carry loads such as resistance, capacitance, motor inductance, fast strain and anti-interference, strong adaptability and strong practicability. It is the first choice for power outage emergency power supply and outdoor power supply.
Solar Panel Working Principle
The working principle of solar panels is to use the photoelectric effect, also known as the photovoltaic effect. Photovoltaic effect refers to the phenomenon that an object generates electromotive force due to the absorption of photons. The photovoltaic effect occurs when sunlight or other light strikes the PN junction of a semiconductor. The photovoltaic effect causes a voltage to appear on both sides of the PN junction, which is called the photovoltaic voltage. By shorting the PN junction, a current will flow.
How Solar Panels Work for Street Lights?

Solar Panel Troubleshooting
Solar panels are made of crystalline silicon. Due to the characteristics of its own crystal structure, it is easy to crack, which constitutes the cause of cracking. Essentially, there are two types, one is mechanical stress and the other is thermal stress. , initially only some small cracks will appear in the cell, which is difficult to detect with the naked eye, but after a long time, it will develop into fragments, which are visible to the naked eye at this time.
How do Portable Solar Panels Generate Electricity?
Pulse Width Modulation (PWM), the regulator has a direct connection between the solar panel and the battery and uses a "quick switch" mechanism to regulate the charge flowing into the battery. The switch remains fully open until the battery reaches the sink voltage, at which point the switch begins to open and close hundreds of times per second to reduce the current while keeping the voltage constant.
What are the Applications of Solar Panels?
